The Shunde advantage
Why Portable Hot Water Comes Out of One District.
Shunde, in Foshan, Guangdong, is one of the densest concentrations of gas-appliance manufacturing in the world — the district that made Foshan a household name in the category.
Within the District
- Heat-exchanger copper
- Shunde / Nanhai — mill stock and coil
- Gas valves & igniters
- Local valve and ignition suppliers
- Injection & die tools
- Tool shops within the district
- Carton & print
- Local pack and litho plants
- Test labs & certification
- Third-party and in-house chambers
- Port of departure
- Nansha / Yantian for container sailings
Parts That Are Not in Anyone’s Catalogue
A specific valve seat, a mesh grade, a masterbatch colour — suppliers here will tool a run for one appliance buyer, because two hundred other makers are on the same street.
Material Provenance You Can Walk To
The copper and the gas-path valves come from named plants a short drive away — not through two trading layers. Ask where a batch of copper was drawn and the answer is a company and an address.
Capacity That Grows Next Door
A volume increase in season two is met by an adjacent line in the same district, under the same audit — not a new factory halfway through your program.

Sizing
How Much Hot Water You Actually Get
A portable heater trades flow against temperature rise — pull more water through and it comes out cooler. This is the production curve for the 6 kW platform. Size from it, not from a headline flow figure.
How a program runs
From Your Drawing to a Certified Container.
Four stages, no skipped approvals. Each one ends in something you can hold or read before the next begins — so nothing is renegotiated after tooling.
- 01
Spec and Fit Review
48 hoursSend a drawing, a reference unit or a brief. The lab reads it against the housing, the gas path, the water supply and the market you are selling into — and tells you what will not fit before anyone quotes.
You getFit notes and a sampling plan
- 02
DFM, Tooling and Costing
3–7 daysDesign-for-manufacture notes on the shell and the assembly, the cube advice that decides what fits one container, the tooling position if you want a private mold, and a transparent cost direction.
You getCost direction, cube plan, tooling quote
- 03
Sample and Spec Freeze
3–4 weeksThe unit is built to the approved line plan and you hold it. Once you approve it, that unit becomes the locked spec — colour target, gas setting, outlet temperature and pack are written onto the order, and there is no second revision to the reference afterwards.
You getA physical approval unit

Production, QC and Loading
On scheduleA pilot lot if you want to test the market first, or straight to a full run. Every batch goes through the gate checks above, and certification is pinned to the locked configuration before the container is sealed.
You getCertified, container-ready lot
Materials and engineering
A Portable Heater Is a Materials Problem.
Sun, moisture, thermal cycling and a propane flame — the unit faces all four every time it runs, then gets drained, trucked and used again. Every material below is chosen against that, not a price sheet.
Oxygen-free copper exchanger
1.03 kg, oxygen-free copper · brazed assembly
Why this oneOxygen-free copper carries heat faster and resists the embrittlement that ordinary copper develops after repeated heating and cooling — the failure mode that turns a two-season unit into a pinhole leak.
What it means in the fieldStable heat transfer across the life of the unit, and an exchanger that can be repaired rather than replaced.
Replaceable battery ignition
Field-replaceable pack · no mains wiring
Why this oneThere is no mains power at a campsite or a job site, so ignition runs entirely off the battery. Sizing the pack against the ignition current is what decides whether one charge covers a trip or an evening.
What it means in the fieldA spent pack is a battery change, not a dead unit.
Stainless anti-downdraft hood
Stainless steel flue hood, anti-downdraft baffle
Why this oneA gust across the flue is how a portable gas heater loses its flame. The hood and baffle are shaped to keep combustion stable when the unit is used in the open, which is the only place it is allowed to be used.
What it means in the fieldFewer flame-out events outdoors, and a flue that does not rust through in coastal air.
Splash-rated enclosure
IPX4 · water from any direction
Why this oneIPX4 is splash protection, not immersion — it covers the water a portable unit actually meets: rain on an open tailgate, spray off a wet bench, a rinse before the unit goes back in the van. Sealing to that standard is what keeps water away from the ignition and the connections.
What it means in the fieldThe unit can be used wet and rinsed outdoors without water reaching the parts that fail once they get damp.

The difference
A Trading Desk Looks Like a Manufacturer — Until Something Goes Wrong.
Both will send you a catalogue and a price. The difference shows up the first time a spec has to change, a certificate is questioned, or a batch arrives off-target. Compare the two below against what you have experienced.
| Aspect | Typical trading desk | Gulfstone standard | How you can check it |
|---|---|---|---|
| Factory access | A showroom and a catalogue. Production is a third party you never meet and cannot name. | You know which plant builds your unit, and you can walk the line before you commit. | Factory tour, on site, with your engineer |
| Material verification | The alloy and the copper are described in an email and taken on trust. | Incoming material is inspected against our standard on arrival, not accepted on a promise. | Incoming inspection records on request |
| Spec changes | A change means a new supplier, a new quote and a reset schedule. | The tooling and the component supply are inside our own base, so a change is a short trip. | Ask what a shell revision does to your lead time |
| Certification | Certificates are discussed, then chased after the container has sailed. | Certification attaches to one tested configuration, and the file pack travels inside the load. | Ask to see the pack that ships with the lot |
| Quality ownership | A defect is a conversation between you and a factory that does not answer to you. | One QC standard across the network, and a factory answer on a batch complaint in 24–48 hours. | Ask who answers a batch-quality claim — sales or the line |
| Landed cost | A competitive unit price, then freight and packing turn your margin upside down. | Cube advice and DFM notes up front, so you are pricing a landed number from the start. | Ask for units per container before you ask for a price |
Certification
Certified for the Market You Sell Into.
Certification attaches to one tested configuration, so it is mapped to the model and the market before the order is placed — not applied for after the container has sailed. The dossier ships inside the load.
| Market | Standard | Covers | Ships with the load |
|---|---|---|---|
| Australia / NZ | AGA · AS 2652 | Gas appliance approval for portable and outdoor units | Test report, approval certificate, declaration of conformity |
| North America | CSA · ANSI Z21.10.3 | Gas-fired water heaters, including the RV configuration | Test report, CSA certificate, DoC, install instructions |
| Europe / UK | CE · EN 26 | Gas-fired instantaneous water heaters | Test report, CE declaration, EN 26 annex, manual set |
| Where required | RoHS · REACH | Material restriction on the housing and the electrical parts | Material declarations, compliance statement |

Three Facts Are Enough to Scope Your Program.
Where the units ship, how many you need in a year, and which model or reference you are working from. Give us those and what comes back is a cost direction and a sampling plan built around your line — not a catalogue.
Manufacturing discipline
Four Gates. Every Batch.
Every batch is sampled to a named standard — most faults are caught before a buyer sees them.
- Gate 01
Incoming material
- Copper, gas valves, burners and igniters
- Housing resin checked against the locked spec
- Gate 02
Sub-assembly and dimensional
- Mounting points, cut-outs, threads
- The tolerances that decide whether it drops into your bracket
- Gate 03
Combustion and gas safety
- Premixed burn-in, dual-valve ignition, flame-out
- Run on every unit, not sampled
- Gate 04
Pack and drop
- Export carton and internal bracing
- 1 m drop on the packaged unit
On the factory floor
You’ve Seen the Difference on Paper. Come and Watch It Hold on the Line.
A trading desk and a manufacturer read the same in a proposal — the tour is where that stops being a claim. Bring your engineer, your QA lead or your agent and audit the Shunde lines the way you would audit any supplier. It is also where the certification behind every unit is earned.
Plan a factory tourWhat You Can Put Your Hands On
- The 24 automatic detection platforms, in-line, on the current run
- Combustion and gas-safety test cells on the finished units
- The heat-exchanger and burner sub-assembly lines
- Incoming-material inspection and the AQL sampling station
- The export pack and the drop-test rig
- Your own sample, on the bench, with the engineer who built it

What Changes, Model by Model
A platform SKU gives you branding and pack with no tooling. A private mold gives you the enclosure itself. Most programs start on the first and step up — you are never forced to fund a mold to get your mark on the unit.

In-house R&D lab
Outdoor Water Heater SKUs, Engineered In-House
Not a sales desk that forwards samples, but a development and compliance lab: give us your drawing or brief and the target market, and the lab engineers it into a production-ready SKU.
01Drawing & Fit Review
Send a drawing, a reference unit or a brief — the lab checks the cut-out, gas path and 12V fit against your vehicle or housing before anything is quoted.
02Prototyping & Revision Rounds
The lab builds the first sample, runs revision rounds against your feedback, and locks a pre-production sample — the version the line will copy.
03DFM, Tooling & Tolerances
The concept becomes a BOM, tooling notes and a tolerance stack — ports, cut-outs and process steps settled before the line runs.
04Cert Samples & Test Evidence
The lab supplies the certification samples and in-house test evidence the file is built on, so the unit that is certified is the unit that ships.

Customer reviews
What Buyers Say
Impartial quotes from the people who sign the PO.
“For the first time in three years, our spring catalog launched on schedule.”
One line had four suppliers across three provinces — three POs, three containers, and coordination overhead that ate the team. Gulfstone consolidated it to one partner and a single PO, then engineered the mixed-container load plan: heavy units as ballast, light SKUs on top.
On-time delivery went 64% to 97% in two seasons, freight dropped 28%, and four weekly vendor calls became one.
Sarah MitchellSupply Chain Director at a North American outdoor brand
“The reorder went back to the same partner without ever going out to bid.”
Four suppliers were each booking their own LCL — four sets of origin charges, four customs entries, four packing lists landing on different days. Gulfstone planned the four streams as one shipment and measured every carton before it left Foshan.
The saving came from the fee stack, not the ocean rate: one CFS charge, one clearance file, one arrival notice. The line has reordered on the same program without a competitive bid.

The Questions Buyers Ask Before Ordering
The six questions buyers ask most often before placing an order — answered up front.
Hot water, anywhereCamping · RV · outdoor
01What is your MOQ for a private-label program?
A platform SKU — our unit, your branding and pack — starts at a low per-SKU MOQ, so a first order does not have to fill a container. A full private mold steps up with the program. Tell us your estimated annual volume and we scope the starting point in the first reply.
02How fast can you get me a sample?
Send a drawing, a reference unit or a brief and the lab returns a sampling plan and custom list, checking fit against your vehicle or housing before anything is quoted. Physical samples follow once the line plan is approved — usually inside 3–4 weeks.
03Which markets can you certify for?
Australia / NZ (AGA), North America (CSA) and Europe / UK (CE), plus RoHS / REACH where your market requires it. Certification attaches to a specific tested configuration, so tell us the market and model and we map the marks you need.
04Can you design my own SKU from a drawing?
Yes — OEM / ODM. Send a drawing, a target market and an annual volume, and the lab develops the SKU: fit review, prototype and revision rounds, then tooling notes before the line is set. Briefed once, in English, with your own drawings.
05Do you mix products in one container?
Yes — mixed-container programs are standard. Send your SKU mix and volumes and we confirm what fits one load, and what it saves against shipping each separately.
06What is your QC standard?
One documented standard across the owned Shunde plant, with in-line checks through every run — 24 fully-automatic detection platforms to 800 pcs a shift. Third-party inspection is welcome at any stage.

RV Tankless Gas
Water Heater Manufacturer,
Built to Your Recess
Built in Shunde, Foshan and matched to the recess, the 12 V scheme and the destination gas setting your vehicle already carries — a drop-in fit, not a re-wire. Combustion is proved on every unit rather than sampled, and a spec question comes back in 48 hours.

Protection
Built to Protect the Unit, So the Shower Is the Last Thing on Your Mind.
Every protection here cuts the burner or the supply when something is wrong — except freeze protection, which runs the burner to stop a hard night splitting the exchanger.
- 01Vehicle Battery Protection12 V DC
- A fault here is the battery you are stranded on
- Sagging, spiking or reversed supply cuts the burner — it never ignites into it
- 02High-Altitude Adaptation5,000 ft · 1,524 m
- Thinner air changes the air-gas ratio
- The controller reads the fan and holds the mixture, so a burner set at sea level does not run rich up a mountain
- 03Freeze ProtectionAuto below 0 °C
- The one protection here that heats instead of cutting
- It cycles the burner to keep the exchanger from splitting — it does not wait for an owner who is not there
- 04Flue-Pressure ProtectionFan-monitored
- A gust across the flue is how an outdoor unit loses its flame
- Fan speed is monitored, and combustion stops before a disturbed draught turns into a bad burn
- 05Dry-Fire ProtectionFlow-proven
- Lighting the burner with no water cracks the exchanger within minutes
- The unit will not burn until the flow sensor has proved water
- 06Flame-Out ProtectionIgnition proven
- Ignition is proved before gas is allowed to stay on
- If the flame fails to establish or lifts off, the gas is cut rather than left flowing
Inside the unit
Five Parts, and the RV Problem Each One Solves.
A tankless heater in a vehicle has four things working against it: a pump that runs at low pressure, a tap that cycles on and off, thin air at altitude, and water drawn from a tank. These are the components that answer them.
The exchanger is on a priced spares list on your program, so a service bay can quote it without a factory email. Gas setting, thermostat and mains-powered variants are a bench change on the same platform — see OEM / ODM below.
Retrofit and cold climate
The Five Ways an RV Water Heater Fails a Buyer.
Retrofit and cold-weather failures look nothing alike on a spec sheet and identical in a warranty bay. Here is what goes wrong, and what the build does about it.
No.Failure modeWhy it happensWhat we do about it
- 01
The Cut-Out Does Not Match
A unit specced from a catalogue photo arrives a few millimetres off the recess — and fails end-of-line the day the trailer is finished.
Send the recess drawing. Unit, door assembly and trim ring are matched to your cut-out before the first run, and the tolerance is written into the QC gate.
- 02
The Gas Path Is Set for the Wrong Market
Propane and LPG behave differently. A unit set for one market then shipped to another runs weak or hot, and nobody notices until a customer does.
Gas setting and orifice are locked to the destination market and certified with the unit — a commissioning step, not an afterthought.
- 03
The 12V Scheme Does Not Match the Panel
A vehicle already carries its own pump and panel. A heater that assumes a different harness means a re-wire in the bay, which is where retrofit labour goes.
The control side runs on DC 12V, and the harness, controller position and connector are matched to the scheme your vehicle already carries.
- 04
The Compartment Is Too Shallow for the Door
A tankless unit is compact, but the door still has to swing inside the bay. Depth is the constraint a plan drawing hides.
320 mm of body depth, and the door assembly ships as part of the build rather than an accessory — so swing clearance is engineered with the unit, not around it.
- 05
It Freezes the First Hard Night
Water left in an exchanger through a cold snap splits the coil — the most common off-season failure on a trailered unit.
The exchanger is drained by a procedure that ships with the unit, so it never sits full through a hard freeze. Winterising is in the manual.
The range
Three Builds. One Platform.
The builds differ in exactly two components. Everything else is common to all three — the same heat exchanger, the same gas path, the same control side, the same dimensions.
- 01
Eco
The entry build — the platform without the tempered-water chamber.
- 02
Plus
Eco plus the tempered-water chamber, which holds the outlet temperature steady through a pressure change at the tap.
- 03
Pro Max
Plus plus a copper front connector. The two additions are the only differences across the range.

OEM / ODM
A Custom RV Water Heater Is a List of Things That Move.
Every row below is a line item you can change, priced against how it changes the build. The first column is what you get if you ask for nothing.
Eleven of these twelve move without new tooling. Only a private shell needs a mould cut, and that is the one line that changes the MOQ.
| Line item | In the platform | Custom, no tooling | Private tooling |
|---|---|---|---|
| Brand and labelRun as an RV tankless water heater OEM program under your brand, or private-label the incumbent panel you already sell. | |||
| Shell and handle mouldA private shell needs a mould cut. Colour and finish do not. | |||
| Cut-out and flangeMatched to your recess from a drawing, so it drops into the bay you already build. | |||
| Gas setting and orificeLocked to the destination market — propane or LPG — and certified with the unit. | |||
| Thermostat rangeThe 35–51 °C band is standard; a market may specify a different range or a fixed setpoint. | |||
| Electrical systemPropane on a DC 12V control side is the platform. A mains-powered or dual-fuel variant is engineered to your market spec. | |||
| ControllerWall controller as standard; position, harness and connector matched to the vehicle. | |||
| Door assembly and trim ringSupplied with the unit so the swing clearance is engineered in, not sourced around. | |||
| Packaging and cartonBarcode, hero art and carton spec to your channel — retail box or bulk export. | |||
| Manual languageAny market, shipped inside the load rather than added at the destination. | |||
| Certification targetLocked to the market you are selling into — the compliance band below maps which standard that resolves to. |
A platform SKU — our unit, your branding and pack — starts at a low per-SKU MOQ, so a first order does not have to fill a container. A private mould steps up with the program.

Compliance
The Mark Follows the Market, and It Travels With the Load.
Certification attaches to one tested configuration. Change the gas setting, opening size or control side and it is a different build — so the target is locked before the tooling, not chased after the container.
Name the market and the model, and the marks follow from it rather than being argued about afterwards.
| Market | Standard | What it covers | Ships with the load |
|---|---|---|---|
| Australia / New Zealand | AGA · AS 2652 | Gas appliance safety for a propane or LPG small water heater, at the market gas setting. | Test report and declaration inside the container. |
| North America | CSA · ANSI Z21.10.3 | Gas-fired storage and tankless water heaters, including the RV and travel-trailer configuration. | Certification file and the mark on the rating plate. |
| Europe / UK | CE · EN 26 | Gas-fired instantaneous water heaters for sanitary use, at the market gas family. | Declaration of conformity and the CE mark on the unit. |
| Where the market asks | RoHS · REACH | Restricted substances across the housing, fittings and the electrical side. | Material declarations with the shipment. |
| High altitude | Tested to 5,000 ft (1,524 m) | Combustion stability where thinner air changes the air-gas ratio — mountain campgrounds and high-desert routes. | Altitude certification with the model you lock. |
Tell us the destination market and the model and we map the marks before the tooling is cut. Third-party inspection — SGS, TÜV or your own agent — is welcome at any build stage, and a plant audit is on file.

Temperature rise
Flow · litres per minute
Inlet water at 15 °C. The curve shape holds across the range — only the rated power changes.
What this build is
Everything the Unit Is,
Before You Commit.
Where it goes, what it runs from, what it is built out of, and how it is operated.
Sized to Go Where a Fixed Line Will Not
One person carries it, and it runs wherever it is put down.
- 400 × 170 × 318 mm, 6.1 kg
- 6 kW of heat input off a single camping bottle
- Stands on the ground, sits on a tailgate, or packs into a shallow bay
Runs With No Mains and No Generator
Ignition is the only thing on the unit that draws power.
- 2500 or 4000 mAh pack, recharged off 12 V
- 80–120 minutes of run time on one charge
- Field-replaceable — a spent cell is a battery change, not a dead unit
Built to Survive Being Outside
A moulded resin shell, not a painted steel box.
- PA66+GF housing — no coating to chip or rust
- IPX4 across the enclosure, including the burner
- Rain on the unit and a wet bench are not failures
Ready to Run With No Installation
No plumbing run and no wiring to install.
- Water in and out on a hose tail with a quick-connect
- Gas through a hose-mounted regulator — propane or LPG
- Handle and bracket points are moulded into the shell
In the field
Built to Cut Out
Before It Becomes a Claim.
Overheat, tilt and dry-burn cutouts, and the control face your end customer actually touches. On a gas appliance the protection answer is what your compliance people ask first, so it is set out here rather than buried in a feature list.
Overheat Protection
The outlet is watched, and the gas is cut before the water runs past the temperature you set.
Tilt Protection
A unit knocked off a tailgate stops firing rather than running on its side.
Dry-Burn Protection
No water in the exchanger means no flame — the failure mode that kills an unfed portable heater.
And how it is operated
One-touch start
A single press lights the burner — no hold-and-purge sequence at the unit.
Display panel
The control face shows the state the unit is in rather than a bare dial.
Set-and-leave
Flow and outlet are set once at the start of a session and the unit runs to that.
OEM / ODM
Your Design.
Our Line.
Your own mark, from a drawing to a shipping container: what moves, and what stays fixed.
01Private Tooling, When the Shape Has to Be Yours
A private tool changes the part itself rather than the mark on it. It is quoted against your drawing once that drawing is locked.
- Part and handle tooling, quoted against the locked drawing
- Tolerance stack and DFM notes settled before any tooling is cut
- Your IP covered under NDA ahead of the first drawing
- The platform stays available if the shape does not need to change
02Literature Written for the Market It Lands In
A manual is a compliance document in most markets, not a leaflet — so it is written for the destination rather than translated after the fact.
- Multi-language manuals written to the receiving market
- Spec sheet supplied alongside, to the production figures
- Artwork and warnings set to the market's own requirements
- Supplied with the pack, so nothing is added after arrival
03Set to the Market, Certified With the Unit
The gas setting and the certification scope are fixed at build, against the market you are selling into — not adjusted at the destination.
- Gas setting locked at build for the destination market
- Certification scope mapped before the order, not applied for after it sails
- The certified unit is the unit that ships — no post-arrival conversion
- Approvals evidence held against the locked configuration
04Your Mark on the Unit, from the First Order
Colour, logo, carton and manual all move without tooling spend, so a first order does not have to fund a mould to carry your brand.
- Housing colour to a Pantone or RAL target
- Moulded in, not painted — the shell is resin, so the colour is in the part
- Logo on the unit and the carton, with barcode and hero art to your channel
- Retail-ready packaging built to the shelf it lands on
Evidence
Checked at the Gate,
And Handed Over as a File.
What is verified before a unit is packed, and what you receive to put in front of your own compliance people. Neither is a claim about a certificate — it is what the shipment arrives with.
01
Incoming Material
Metals and gas-path parts checked against specification before they reach a line.
02
Dimensional and Fit
Cut-outs and fittings checked to the drawing the order was built from.
03
Combustion
Burn-in run on the unit, so the flame is proven before the enclosure is closed.
04
Gas Safety
Over-ignition and flame-out checked on the assembled gas path.
05
Drain and Freeze
Residual-water check, because a trapped charge is what cracks an exchanger.
06
Export Pack
Carton and drop check against the pack the container will actually carry.
In the shipment file
- Approvals evidence for the locked configuration

Parts That Are Not in Anyone’s Catalogue
A valve seat, a mesh grade, a masterbatch colour — suppliers here tool short runs, because two hundred other makers share the street.
Material Provenance You Can Walk To
Copper and gas-path valves come from named plants a short drive away — ask where a batch was drawn and you get an address.
Capacity That Grows Next Door
A rise in season two is met by an adjacent line under the same audit — not a new factory found mid-program.

Eco
Flame-type pulse ignition
The platform at its simplest — one knob, a flame-type control and an LED that reports the state.

In the field
Built to Cut Out
Before It Becomes a Claim.
The same nine cutouts on all three builds — the control level changes what the unit does, never how it fails safe.
Tilt Protection
Knocked off a tailgate, it stops firing instead of running on its side.
Scald Protection
The gas cuts before the outlet runs past the temperature you set.
Flame-Out Protection
Ignition is proved before gas stays on; a lifted flame cuts the supply.
Short-Circuit Protection
A supply fault trips the unit, not the harness.
Overcharge Protection
Stops accepting charge at full, so a left-on charger cannot cook the pack.
Overvoltage Protection
A spike on the DC input is clamped, not carried into the controller.
Over-Discharge Protection
Cuts before the pack is drawn flat — what kills a stored cell.
Overcurrent Protection
The draw is limited at the board, so a stalled pump cannot cook the wiring.
Fault-Code Display
Faults report as a code, not a dead machine with no answer.

A Short Brief Is Enough: Which Build, Which Market, How Many a Year.
You have seen the standard and what it takes to make the line yours. Tell us the market and the volume, and the reply is a cost direction and a sampling plan — with the documents below to check it against.
Certification and quality
Certified for Your Market,
Documented for Your Buyer.
Certification attaches to one tested configuration, so it is mapped to the build and the market before the order is placed. The file ships inside the load.
The configuration
One Certification Configuration, Whichever Build You Carry
Eco, Plus and Pro Max share the exchanger, the gas path, the burner and the enclosure — so they certify as one tested configuration. A buyer taking two builds, or moving from one to another, carries one set of approvals rather than three.

Your Design.
Our Line.
Your own mark on any of the three builds, from a drawing to a shipping container: what moves, and what stays fixed.
Free to Change
Your Mark on the Unit and the Pack
No tooling. Your colour, logo and carton are quoted in the first reply.
Colour, logo, carton and manual move without tooling spend, so a first order does not have to fund a mould to carry your brand.
- Housing colour to a Pantone or RAL target
- Moulded in, not painted — the shell is resin, so colour is in the part
- Logo on the unit and the carton, with barcode and hero art to your channel
- Retail-ready packaging built to the shelf it lands on
Set to the Market, Certified With the Unit
No tooling. The unit arrives set and certified for your market.
The gas setting and the certification scope are fixed at build, against the market you are selling into — not adjusted at the destination.
- Gas setting locked at build for the destination market
- Certification scope mapped before the order, not applied for after it sails
- The certified unit is the unit that ships — no post-arrival conversion
- Approvals evidence held against the locked configuration
Engineering & Tooling
A Drawing Review Before Anyone Quotes
No tooling. The fit and DFM review comes back before anyone quotes.
Send a CAD file, a reference unit or a sketch. The engineering team reads it against the housing, the gas path and your market, and comes back with what will not fit before a price is attached to it.
- DFM notes on the shell, the handle and the assembly
- Tolerance stack and wall-thickness called out before tooling
- Fit review against the destination market’s requirements
- A sampling plan in the first reply, not after the PO
A Private Shape, When the Platform Is Not Enough
A private mould, quoted against your drawing once it is locked.
A private tool changes the part itself rather than the mark on it, quoted against your drawing once that drawing is locked.
- Part and handle tooling, quoted against the locked drawing
- Tolerance stack and DFM notes settled before any tooling is cut
- Your IP covered under NDA ahead of the first drawing
- The platform stays available if the shape does not need to change

What it is for
An Outdoor Wash Point,
Where There Is No Supply to Tap.
A fixed outdoor water heater for sites that run on a propane cylinder and no mains power. It heats on demand as the tap opens, and shuts the gas off the moment the water stops.
Fixed installation
Outdoor Wash Down
- Posts, outbuildings and workshop yards with no mains hot water
- Mounted to a wall or a stand with a weather cover over it
- Not for direct rain exposure — siting is part of the brief
No mains power
Off-Grid and Remote Sites
- Runs from a propane cylinder and two cells of DC 3 V ignition
- Continuous pulse ignition needs no pilot flame to keep lit
- Water–gas linkage valve starts the burner on flow, not a switch
Private label ready
Retail and Hire Fleets
- A single-model SKU under your own brand and carton
- Carton and manual language set for the destination market
- Spares list carried against the production BOM
What it is made of
The Parts Behind the Sheet,
Named.
Each part below is a row on the datasheet further down — opened up, so the figure and the component it describes read as one thing.
Tin-Dipped Copper Tank
A 1.0 kg copper heat exchanger, tin-dipped for corrosion resistance along the water path — the coil the flame plays across.
Water–Gas Linkage Valve
Gas is admitted only while water is flowing. Turn the tap on and the burner lights; turn it off and the gas stops — no separate gas switch.
3-Row Harmonica Burner
A three-row burner with 6 × Φ0.69 mm nozzles, sized to the 32,000 BTU/hr input for a stable flame across the flow range.
80 °C Limit Thermostat
A fixed limit that interrupts the burner before the outlet runs past 80 °C, independent of the manual knob position.
Pressure-Relief Valve
A mechanical over-pressure device on the water side, relieving before the tank sees a strain the coil cannot hold.
Powder-Coated Sheet-Metal Shell
Face and base in sprayed sheet metal — a painted steel housing rather than a moulded one, so it takes an outdoor fixing and a custom colour run.
The specification
Every Figure This Model Ships to,
And the Connections It Arrives With.
The production figures an installer works from and a buyer reads against a PO — grouped the way the unit is built, not the order the factory worksheet lists them in.
Figures are the production specification for this build. Where the source sheet leaves a value open, it is confirmed against the production sheet rather than shown as a dash.

When something goes wrong
It Cuts the Gas
Before Anything Is at Risk.
Four cut-outs on the water–gas path, and the running order that opens and closes the burner. None of them needs a person to act.
Flame-Out Protection
If the flame lifts or dies, ignition stops proving and the gas supply cuts.
Over-Pressure Protection
The pressure-relief valve discharges on the water side before the coil is over-strained.
Over-Temperature Limit
The 80 °C thermostat interrupts the burner at the set ceiling.
Water–Gas Interlock
No flow, no gas — the linkage valve closes the burner when the water stops.
Open the tap
Water flows through the linkage valve, which opens the gas path in proportion.
Ignition proves
Continuous pulse ignition fires on the 3 V supply and proves a flame before gas is held.
Heat the water
The burner plays across the copper coil and the outlet runs to the temperature the knob and flow set.
Close the tap
Flow stops, the linkage valve closes the gas, and the burner goes out — nothing runs until the next draw.
What you bring to it
The Connections, the Supply,
And the Place It Goes.
What the unit arrives expecting on site — read it against a drawing before the fixing point is set, not after.
- Gas inlet
- 5/8-18 UNF
- Propane at 27.4 mbar, from a regulator on the cylinder.
- Gas type
- G31 propane
- Set for propane; other gases need a different nozzle and gas setting, fixed at the factory.
- Water in / out
- G1/2
- A standard half-inch thread on both sides — feed in, hot out.
- Water pressure
- 0.025–0.8 MPa
- Below the floor it will not fire; above the ceiling it protects itself.
- Ignition supply
- DC 3 V
- Two cells drive ignition only — the unit takes no mains power.
- Siting
- Outdoor, fixed
- Open flue, mounted outdoors with a cover — not exposed to direct rain.
How it is made
Briefed Once, in English,
And Proven on Every Unit.
What happens between a drawing and a loaded container on this model — the brief, the test, the plant and the records that travel with the batch.
Briefed Once, in English
Drawings, carton art and the market setting go into one brief, so nothing is re-explained between the sample and the production run.
100% Gas-Tested
Every assembled unit is burned in on the gas path and flame-proved before it is packed — not sampled.
Built at the Shunde Plant
The coil, gas path, burner and shell are assembled and tested in-house in Shunde, Foshan, where the district’s suppliers sit a short drive away.
Per-Batch Records
Each batch carries its own inspection and combustion records, so a claim can be traced to the run that made the unit.
Make it yours
What Moves on This Model,
And What It Takes to Start.
A platform SKU under your own mark needs no tooling — the panel is sprayed steel, not a mould. Add a private shape only when the shell itself has to be yours.
No Tooling
Your Mark on the Unit and the Carton
Colour, logo, carton and manual move without a mould, because the housing is a sprayed sheet-metal panel rather than a moulded shell.
- Housing colour to a Pantone or RAL target
- Logo on the panel and the carton, with barcode and hero art to your channel
- Carton and manual in the destination language
- Retail-ready packing built to the shelf it lands on
No Tooling
Set to the Market, Certified With the Unit
The gas setting and the certification scope are fixed at build against the market you sell into, not adjusted at the destination.
- Gas setting and nozzle locked for the destination market’s gas
- Certification scope mapped before the order, not applied for after it sails
- The certified unit is the unit that ships
- Approvals evidence held against the locked configuration
Engineering
A Drawing Reviewed Before Anyone Quotes
Send a CAD file, a reference unit or a sketch. Engineering reads it against the panel, the gas path and your market, and comes back with what will not fit before a price is attached.
- DFM notes on the panel, the mountings and the assembly
- Fit review against the destination market’s requirements
- A sampling plan in the first reply, not after the PO
- Your drawings covered under NDA ahead of the first one
Application
A Hot-Water Point You Carry,
Not One You Plumb In.
A tankless propane heater on a 12V supply, built to be lifted out and set up wherever the water is. It heats as the tap opens and stops the moment the water does.
Carried, not fixed
Camping and Outdoor Showers
- A handle and a 370 × 290 × 116 mm case — one person lifts it and sets it up
- Tankless: it heats as the water runs, with no tank to fill or pre-heat
- Water-activated ignition, so the shower runs without a match or a pilot
Runs on the vehicle supply
RV, Camper and Off-Grid Rigs
- DC 12 V input matches the system already on board an RV or camper
- Propane from the cylinder the rig already carries at 2,750 Pa
- Starts on the flow of the tap — no mains, no switch to leave on
Where a hot tap is needed for a while
Gardens and Temporary Sites
- Garden washing, a temporary wash point, a jobsite standpipe
- Standard G1/2" connections match common fittings
- Packed away when the job is done — it does not stay on the wall
Heat control
Tankless Heat,
Held by a Staged Flame.
Instant hot water with no tank to wait on, and a burner that steps through three flame settings instead of only on or off — the mechanism the "constant temperature" name rests on.
Stage 1
Low Flame
The burner drops to its lowest setting once the outlet is up to temperature — it holds the heat instead of overshooting it.
Stage 2
Mid Flame
The middle setting carries a normal draw: an outdoor shower or a wash point running at a steady flow.
Stage 3
High Flame
Full flame for a cold feed or a fast fill, then a step back down to hold the outlet rather than run past it.
The burner holds one of three flame settings and steps between them as the outlet and the flow move. Full flame for a cold feed or a fast fill, then a step down to hold the outlet — the mechanism behind the constant-temperature name.
Specification
Every Figure This Build Ships to,
And Its Connections.
The production figures an installer works from and a buyer reads against a PO — grouped the way the unit is built, not the order the factory worksheet lists them in.

- The same thread on the gas side, for a hose and regulator.
Protection
Four Cut-Outs,
Before Anything Is at Risk.
Each protection below stops the unit on its own — none of them waits for a person to act. They are the checks an importer reads first, because the liability for what ships travels with the container.
Flame-Failure Protection
If the flame does not prove or lifts while gas is flowing, the supply is cut.
Overheating Protection
A thermal cut-out stops the burner before the outlet runs past its limit.
Dry-Burn Protection
With no water in the coil, the unit will not fire — it cannot heat an empty exchanger.
Over-Pressure Protection
The unit protects itself when the incoming water pressure runs high.
Open the tap
A sensor reads the water flow and the unit wakes — nothing has run until now.
Ignition fires itself
The burner lights automatically on the flow. There is no pilot and nothing to light by hand.
Heat at the set stage
The flame holds at one of the three stages, giving up to a 25 °C rise at the rated flow.
Close the tap
Flow stops, the burner goes out, and the unit returns to idle between draws.
Sourcing risk
What Goes Wrong in the Field,
And the Build That Answers It.
A portable heater is judged by what fails after the season, not by a spec sheet. Five of the risks that come back to a buyer of a portable line — and what this build does about each.
A Heater That Fails Its First Season
Pitted coils and seized fittings turn every unit you sell into a claim against your brand, not the factory that made it.
What this build does
A weather-resistant metal case and a build set for propane only — the configuration confirmed against the production sheet before the order, not after.
A Unit That Will Not Run Off the Rig
A heater that wants mains power does not fit a camper, a van or an off-grid cabin, and rewiring around it undoes the saving.
What this build does
It runs on the 12V supply the vehicle or the cabin already carries, so it fits the rig rather than fighting it.
Scalding and Cold Patches
A single-stage burner overshoots and undershoots as the flow changes, and the person in the shower feels every swing.
What this build does
A flame that steps through three stages holds a steadier outlet as supply and flow move — the mechanism behind the constant-temperature name.
A White-Label Order That Needs Tooling
A private shape usually means a mould, and a mould means a volume a first order may not reach.
What this build does
The case is a metal shell, so colour, logo, carton and manual move under your mark with no tooling to buy.
Approvals That Arrive Too Late
A unit shipped before its approval lands is a container you cannot sell, sitting against your cash.
What this build does
The certification scope is mapped and locked before the order is placed, so the certified unit is the unit that ships.
Programme
A First Order, Stage by Stage —
And What Each One Holds.
A portable program follows a fixed order, and the two questions a buyer asks at every stage are the same: what is locked, and when. Here is the run this model follows, from the first brief to the sealed container.
Enquiry to Scenario Plan
Inside 48 hoursSend the destination market and an annual volume. What comes back is a cost direction, a sampling plan and the settings this model ships with — a costed reply, not an acknowledgement.
Sampling and Approval
Off-toolSamples are built to your finish, dimensions and packaging and checked against the spec, so what is approved is what the line runs.
Certification and Locking
Before the orderThe gas setting and the certification scope are fixed at build against your market. The configuration is locked before production, not adjusted at the destination.
Production
Gas-testedThe build runs against the locked configuration, and every assembled unit is burned in on the gas path and flame-proved before it is packed — not sampled.
Loading and Consolidation
One containerUnits, spares and accessories are packed to one load and one packing list, so a first order does not have to fill a container on its own.
Compliance
Certified for the Market
The Container Is Going To.
Certification scope is mapped before the order, not after it sails. Tell us the destination, and the unit is fixed, tested and documented against that market — the certified unit is the one that ships.
Gas markets — Australia / NZ · North America · Europe / UKAGA · CSA · CE gas-appliance programmesThe unit is built, tested and certified to the destination programme, with the approvals pack held against the locked configuration — the certified unit is the unit that ships.
Chemical complianceRoHS / REACHThe declaration set travels with the container paperwork, not as a summary certificate sent ahead of the goods.
Pre-shipmentISO 2859-1, AQL 2.5Packaged units are sampled and reported before anything is cleared for loading; the inspection report ships inside the container.

The visit
From First Enquiry to the Debrief.
Five stations, in the order they happen. What you see at each one is what the tour is for.
- 01
Before You Land
We shortlist the lines your product would actually run on and confirm they are scheduled for the week you arrive. You get the itinerary before you book the flight, not after.
- 02
The Floor, at Your Pace
The stations are sequenced to your procurement priorities — the parts you are hardest to source first. Each is time-boxed so you are not marched through, with buffer left for the one that deserves a longer look.
- 03
An Engineer Beside You
A Gulfstone manufacturing engineer walks every station with you, translating spec as it is discussed and flagging the production detail a general interpreter would drop. You hear what the line lead actually said.
- 04
Samples on the Bench
Bring a drawing, a cut-out or an incumbent unit and it goes on the bench next to the machine that would run it. Tooling changes, material substitutions and fitment questions get answered standing up, not over email.
- 05
The Debrief
You leave with a written read on what the plant can hold: capability by station, the two or three tolerances that would decide your spec, and where the honest risk sits.
What you can verify
What a Morning on the Floor Settles.
A proposal reads the same from a trading desk and a manufacturer. These are the things the tour exists to let you check yourself.
Livegas test cell
Watch a Unit Go Through the Gas Test
Stand at the combustion cell while a unit from the schedule is run and flame-proved. It is a check you watch happen, rather than a claim you read off a certificate afterwards.
1lot, followed
Follow One Batch End to End
Pick a lot on the line and walk it with the engineer through every station it still has to clear — rather than arriving at a batch staged for the visit.
2ways to tool
Whether Your Housing Needs a New Mould
Your own mould, or ours with your branding and pack. Standing next to the machine, a tooling question gets costed in minutes instead of an email thread.
Lastbatch record
Open the Records from the Lot Before You
Ask for the per-unit gas log and the batch record from the run that finished before you arrived, and read them against the line standing in front of you.

How Your Container Is Packed
Mixed-container loading against a documented load plan, and an export pack with its own drop-test rig. Ask to watch a carton come off the line and go through the pack station.

What Happens After the Container
The warranty term, the returns window and the spares list ship with the program. Ask the after-sales desk directly what a service centre can get without a factory email.
What a visit settles is whether the plant is what it says it is. The quality system behind it — the gates, the standards and the sampling — has its own record.See the Quality Control System

How to start
From the First Email to the Plant Floor.
The tour is a scheduled engagement rather than an open day, so the line and the engineer are held for you.
- 01
Send the Brief
Your product, the destination market, your annual volume and any drawing you have. One page is enough to scope it.
- 02
Talk to the People Who Build It
A call with engineering and production rather than a sales desk, so the stations you need to see are set by the people who would run them.
- 03
Lock the Dates
We hold the line schedule and the engineer for the week you arrive, and send the itinerary before you book travel.
- 04
Walk It
Fly in. Walk the stations, put your sample on the bench, and leave with the written debrief.
The tour is built for programs in the USD 400k+ a year band — a first order that fills part of a container is usually better served by the sample route.

One Approved Sample, Held as the Reference for the Whole Run.
A specification is not a document you send once. It is a value that has to survive tooling, the first article, the run and the container. This is where each one is held, and what has to happen before it is allowed to move.

The line
The Engineers Who Own the Water Heater Production Line.
Four desks sit on your program. Each one owns a decision and signs for it, so the answer you get is the answer the line will build to — not a sales reply relayed from a workshop.
| Role | What they own | What they sign |
|---|---|---|
| Development engineer | The fit of your drawing to the line — cut-out, gas path, tolerances and the feasibility ruling. | The feasibility note and the fit record. |
| DFM and tooling engineer | The tolerance stack, the bill of material, jigs and moulds, and the costed direction. | The tooling drawing set and the first-article report. |
| Line lead | The scheduled run — configuration, workmanship and the pace the packing schedule is built around. | The batch record and the pre-shipment release. |

What We Make, and What the Network Makes.
Heaters are engineered, assembled and tested on Gulfstone lines; other components come from a partner network held to the same document discipline — so a program covers a whole outdoor system, not just the heater.

Evidence
Certification, Gates and the Records That Ship With the Unit.
Certification attaches to the tested configuration, not to the model name — which is why the certificate sample and the production sample are the same build. Everything the compliance file needs is produced during the run, not reconstructed afterwards.
Certified by market
Named to a Standard, Not a Slogan
A certificate belongs to the configuration that was tested and approved, not to a model family. The document that clears a market therefore describes your build, and it is issued before the run is released.
- Destination market
- Tested configuration
- Declaration per order
Quality gates
Four Gates, Held per Batch
Each gate is a hold point, not a tally. A lot does not advance until the check is signed and the record filed, so what shipped can always be shown to have passed — not asserted after the fact.
- Held until signed
- Recorded per lot
- Traced to the shift
Batch records
A Container That Traces to a Shift
Per-lot records are retained, so a unit in the field can be traced back to the batch, the shift and the tests it passed. Your own inspector — or a third party — can attend any gate.
- Held per lot
- Traced to the shift
- Released to the buyer
Packing and loading
How Your Water Heaters Are Packed, Cubed and Loaded.
The carton and the load plan are agreed before the run opens, so what fits is settled on paper rather than at the dock. Products are mixed into one container where the order allows, and the load plan you sign is the one the warehouse builds to.
- Export carton
- Built to the drop and compression standard for the destination channel.
- Internal bracing
- Units blocked and braced so a packaged unit survives the drop test.
- Mixed-SKU loads
- Heavy units as ballast, light SKUs stacked — one container rather than several.
- Load plan
- Issued and signed before the run, so packing is a decision not a discovery.
Brand and tooling
Private Label, Tooling and Who Owns the Design.
There are two ways to put your brand on a Gulfstone heater, and they differ in what you own. Neither one puts your drawing in front of another buyer.
Path A
Your Mould
You hold the tooling and the drawing. The enclosure, interface and layout are yours alone, and no other program can be built from them.
- Changes
- Enclosure, interface, layout and cut-out built to your drawing.
- Stays standard
- Gas path, safety systems and test discipline stay on the proven platform.
- Ownership
- Tooling and drawing held in your name.
Path B
Our Platform, Your Brand
The heater runs on a proven platform; your identity carries the case, the controller, the literature and the carton. The fastest route to a launch.
- Changes
- Colourway, controller, badge, literature and carton.
- Stays standard
- Enclosure, gas path and safety systems stay standard.
- Ownership
- Brand and artwork are yours; platform tooling stays ours.
- MOQ
- A platform SKU starts low; a private mould steps up with the program and can be staged across runs.
- NDA
- A mutual NDA sits ahead of the first drawing, before any technical detail changes hands.
- Containment
- A tooling or drawing built for your program is not quoted, shown or built for another buyer.
Getting started
From First Sample to Repeat Order.
You do not have to commit to a container to start. Each rung is a stop point you can take a decision on, and the program only widens when the unit in your hand is the one you want.
Sample
A physical unit built to your spec, in your hand.
- What you bring
- A drawing, a reference unit or a written brief; the market it sells into; the housing or vehicle it has to fit.
- What counts as a pass
- The sample matches the drawing on the parts that decide the install — housing, fitment and gas setting — and the pack is settled at the same time.
Stop here and take the sample to your own market test.
Pilot Lot
A small release off the same line, on the same released drawing.
- What you bring
- A purchase order for the pilot quantity, plus artwork if the pack changes for your brand.
- What counts as a pass
- Every unit in the lot was built on the released drawing and can be checked against the same record as the sample.
Stop here and trial it with your buyers.
Production Run
The scheduled run, released against the same frozen reference.
- What you bring
- The sailing window, the destination port, and the signed reference from the pilot.
- What counts as a pass
- The run ships against the frozen reference — no re-reading of the brief and no drift between the pilot and the container.
Scale as the orders come in.
A rung that does not pass does not roll forward. The sample is revised or the brief is reopened, and the pilot does not start until the reference is signed.
The platforms that carry the most programs are the ones buyers came back to. Repeat orders run at 98%.

Hold point
Quality control · Shunde, Foshan
Water Heater Quality Control,
Held at the Gate, Not Promised After It.
Gulfstone builds off-grid outdoor water heaters for importers, RV builders and outdoor brands. Quality is not a final inspection we promise — it is a set of gates inside the build, each with a standard, a sampling level and a hold point that stops the lot until the check is signed.
- Standard
- Per check, named
- Sampling
- AQL 1.0 – 4.0
- Gas test
- 100% of units
- Records
- Per lot, retained
Batch record
The gates
Four Gates, Each With a Hold Point
The Lot Does Not Move Past.
A gate sits inside the build, not at the end of it — a lot does not advance until the check is signed and the record filed. Sampling is per-check, not one level for the line: the two gas checks run on every unit.
Incoming material
Check
Copper, gas valves, burners and igniters, and the housing resin checked against the locked specification.
StandardMPI 2.0
SamplingAQL 1.0
Hold
No material enters the line on a supplier’s word — a lot that fails the check is rejected at the door, before it can be built into a unit.
Hold pointSub-assembly and dimensional
Check
Mounting points, cut-outs and threads — the tolerances that decide whether the unit drops into your bracket.
StandardISO 2859
SamplingAQL 2.5
Hold
A sub-assembly does not move to combustion until its dimensional check passes against the released drawing.
Hold pointCombustion and gas safety
Check
Fully-premixed burn-in, dual-valve ignition and flame-out, run on every unit — not sampled from the batch.
StandardEN 26 / CSA 4.3
Sampling100%
Hold
A unit with a gas fault does not leave this gate, and a fault cannot be averaged away by sampling — the check runs on the whole batch.
Hold pointPack and drop
Check
Export carton and internal bracing, proven with a 1 m drop on the packaged unit.
StandardISTA
SamplingAQL 4.0
Hold
A pack with a failed drop test is re-engineered before the container is packed — the load plan is not built around a carton that will not survive.
Hold pointThe test lab
The Instruments Behind the Claims,
In Our Own Plant.
A certificate is issued against a test, and the test needs equipment. These benches sit in the Shunde plant, so a combustion or material claim is checked here rather than sent out and waited on.
- 01
Combustion and Flue-Gas Analysis
Gas-boiler furnace performance and flue-gas analysis. The combustion that proves a burner runs clean and a flame proves out is measured here, not assumed.
- 02
Gas Line Pressure and Leak Test
The gas path is pressure-tested and leak-checked on the bench before a unit is assembled around it — the rig behind the 100% gas-safety gate.
- 03
Spray and Moisture Testing
Spray and moisture benches for the enclosure and the electrical side, held to the market a unit is built for.
- 04
The Mute Room
A sound-controlled room for ignition and running noise, so a performance claim about how a heater sounds is measured rather than described.
- 05
In-Line Detection
Fully-automatic detection platforms run beside the assembly, testing each unit as it is built rather than pulling a sample once the line has finished.
Tell us which model you are sourcing and we will say which of these benches it is run through — from the combustion analysis down to the test that proves the gas path.
Ask Which Benches Your Model Runs OnIn-line, not at the dock
A Fault Is Caught Where It Is Made,
Not Found at the Dock.
A check on finished goods only sorts what the line already built — by then the cost is sunk and the cause buried. So the checks sit where the risk is created, and a lot holds until that station's check is signed.
- 01
At the Station
The check runs where the operation runs, against the released drawing or the locked specification — not on a sample pulled at the end of the line.
- 02
Before It Is Closed Up
The check a fault can hide behind happens before the unit is sealed, so a gas path or a joint is proved while it can still be seen and corrected.
- 03
Held, Then Released
A gate that has not been signed holds the lot. Nothing advances past an unsigned gate, so a defect is corrected at its source rather than reworked at the end.
- 04
Tied to the Shift
Each result is written against the batch and the shift that produced it, so a unit in the field can be traced back to the run, the operator and the tests it passed.
What ships with the container
The Quality Records Travel With the Order,
Not in a Follow-Up Email.
Every item below is produced during the run and filed against the order it belongs to, so the compliance file is assembled from what happened on the line rather than reconstructed after the container has gone.
Per-Unit Gas Test Log
The combustion and gas-safety result for each unit in the batch — the record behind the 100% claim, attached to the units it covers.
Batch Record
The lot traced to the shift that built it, naming who ran the checks and who signed each gate off.
Inspection Report
The incoming-material and dimensional results, with the measuring equipment each check was run on.
Compliance Declaration
The certificate and test evidence issued against the configuration approved and shipped, not the model family in general.
Third-Party Report
Where a buyer sends SGS, TÜV or their own agent, that inspection report is filed with the order alongside ours.
A claim about a shipped unit is answered from this pack — the document a buyer holds, not a general assurance.
Inspection and audit
Send Your Own Inspector,
Or None of This Is on Trust.
Quality control is only useful if you can check it. A buyer is welcome to attend the gates, invite an agency, or ask for the paperwork and go through it against the line that produced it.
Attend a Gate in Person
Come to the plant and watch a lot pass through any of the four gates, or book the visit as part of a factory tour.
Send an Agency
Third-party inspection by SGS, TÜV or your own agent is welcome at any gate — we schedule the line so the check can run alongside production.
Ask for the Records
The batch record, the per-unit gas log and the inspection report are released against a lot, so a claim can be read against the evidence rather than taken on trust.
A third-party audit of the plant is already on file, and an engineer answers a technical quality question inside 48 hours.

OEM / ODM · Shunde, Foshan
Outdoor Water Heater OEM / ODM — from Your Brief to Your Brand.
Gulfstone builds off-grid outdoor water heaters for importers, RV builders and outdoor brands, under their name and to their market. Arrive with a finished drawing and we build it; arrive with a market requirement and we design it with you.
One product, four states
V1Brief
Your requirement, market and volume.
V2Form
The first buildable shape, engineered.
V3Revision
Your feedback folded back in.
FrozenReference
The signed unit the line copies.
The two terms
OEM and ODM Are Two Different Jobs.
The words get used interchangeably, which is why quotes come back wrong. Here is what each one means when Gulfstone runs it.
OEM
Original equipment manufacture
You own the product and the design. Gulfstone builds it — to your drawing, your specification and your brand, on our line, under your name.
What that meansThe product is already decided; the job is to make it well, at cost, in volume.
ODM
Original design manufacture
You own the market, not the drawing. Gulfstone adapts a proven platform to your brief — the shape, the features and the brand are developed with you.
What that meansThe product is not yet decided; the job is to develop it, then make it.
The Rule
Arrive with a finished drawing and you are buying an OEM program. Arrive with a market requirement and a target price and you are buying ODM — the design work is part of what you get back.
The two routes
Which One You Need, in Five Lines Each.
Both routes end at the same place — your brand on a certified, container-ready unit. What differs is who owns the design and how much development sits in front of the first order.
Private label on a proven platform
- You arrive with
- A finished drawing, a reference unit, or a platform you have already selected.
- Best for
- A brand or exporter that wants its own product without running a development program.
- We supply
- Build to your specification on our line — configuration, branding, packaging and documentation to your market.
- You own
- The brand, the artwork and the product identity.
- Trade-off
- The shorter route to a branded launch: the platform is already tooled and in production.
Development built to your brief
- You arrive with
- A market requirement, a target price, a use case — or an early sketch.
- Best for
- A brand building a differentiated product it will own, rather than a label on a catalogue unit.
- We supply
- Design and engineering: the development lab turns the brief into a buildable product, then the line makes it.
- You own
- The design you commissioned, and the tooling built for it.
- Trade-off
- The longer route, and the one that ends in a product nobody else sells.
Whichever route you take, the design work sits with Gulfstone’s own development lab — the same team that will hand the released drawing to the line.
See What the Development Lab DoesWhat we develop from
You Do Not Need a Finished Drawing to Start.
A brief does not have to be complete. Send what you have and where the gaps are — filling those gaps is the first thing the development work does.
Send what you have
- 3D CAD or 2D drawings
- A benchmark or competitor unit
- A specification or feature list
- A market, a use case and a target price
- A photograph and a rough sketch
What comes back first
- 01A Feasibility Note
What is buildable as you have described it, what has to move, and the open questions.
- 02A Cost Direction
Where the product lands on tooling, unit cost and freight — before the design is frozen.
- 03A Sample Plan
How many revision rounds the shape needs, and what each round is for.
If the brief fits a platform already in production, we say so — that is a shorter route to a launch than a new tool.
The development cycle
The Shape Changes Until It Stops.
Each round runs against the same unit, so the differences are the only thing under review. It ends when the shape is right — round two or round four.
V1
Concept
The brief becomes a buildable form — proportions, feature set, the interface and the mounting.
Reviewed with you before anything is cut.V2
First Sample
A physical unit, built and tested, so the argument moves from the drawing to something in your hands.
Your revision list drives the next round.V3
Revision
The changes go back in and the unit is rebuilt. Most programs settle inside one or two of these.
Sign-off, or one more round.How many rounds a product takes is decided by what changes between them, not by a schedule.
The sample gate
What Gets Signed at the Sample.
A sample is not a formality before the quote. It is the point where the product stops being a description and becomes the thing the line will copy, so it is worth knowing what you are signing and what has to happen first.
The sample passes when all three hold
It fits its host
Housing, cut-out and the interface line up with the vehicle, the recess or the panel it was specified for. A unit that does not drop in is not a cosmetic issue.
It matches what you ordered
Gas setting, controls and finish are the ones on the brief, with no substitutions carried over from another program.
A second unit would match it
The parts that matter are documented to a measurement, not a photograph, so the next build is checked against a number rather than a memory.
What comes back with the sample
- Measurement
- The critical dimensions signed off, so the second unit has something to be held to.
- Frozen reference
- One approved unit and its revision locked as the record the run is made against.
- Open items
- What the sample did not settle, and whether it needs a round or a decision outside the product.
If it does not pass
- One revision round on the same reference.
- Or a reopen — the brief moves, and the round count restarts rather than being argued down.
IP and exclusivity
Who Owns the Design When the Program Ends.
It is settled in writing before a file changes hands, and it follows the route you took rather than a default. Nothing designed for one buyer is offered to another.
01
Ahead of the First Drawing
A mutual NDA sits between us before any technical detail moves — the file does not travel on a promise.
02
Under OEM
Your drawing stays yours. Gulfstone builds to it and holds no claim on the product, the identity or the tooling built for it.
03
Under ODM
The design you commissioned and the tooling cut for it are yours — built for your program, not held back as a platform we can resell.
04
Containment
A tool or a design developed for your program is not quoted, shown or built for another buyer, for as long as the agreement says.
Program scope
How Far a Program Can Reach into the Build.
A program can be one unit or a system. Everything a finished product is made of is sourced, held to the released specification and documented, so the carton that lands is the product you approved — not the unit and a box of loose parts.
- The Unit
- The heater, its gas path, safety systems and controls, built and tested as one assembly.
- The Enclosure
- Housing, interface and mounting, to the drawing or the platform you chose.
- The Accessories
- Inlet and outlet fittings, hoses, brackets and the parts a buyer expects in the box.
- The Presentation
- Carton, literature, labels and the pack build, to your channel rather than a generic export box.
Sourcing a wider scope into one program is how a system ships as one load instead of five.
Commercial shape
What Moves the Minimum, and by How Much.
The opening order on a water heater program is not a fixed number — it follows two decisions: whether new tooling is cut, and how much of the build is new. Read it as a lever, not a threshold.
No new tooling means the first order can start small. A new mould commits real money, so it raises the opening volume and is recovered across the program rather than on the first run.
A program that takes on the enclosure and the presentation carries more of the build than one that starts from a platform and changes the branding. Scope moves the order the same way tooling does.
A commitment does not have to land at once. Tooling programs are usually staged across agreed runs, so the volume arrives with your demand rather than ahead of it.
What the unit price is built from
- Certification
- Every market the unit has to be cleared for, and whether the test evidence covers this configuration or has to be run for it.
- Freight
- How the order fits a container. A mixed load across models is priced on the space it uses, not a container per line.
- Packing
- The carton, literature and label build your channel requires — settled with the sample rather than after it.
- Tooling, scope and staging
- The three levers above. They set the opening volume and spread the tooling cost across the program.
None of these is a published number. Say what your market and volume are and the direction comes back against your program rather than a shelf.
The decision
OEM or ODM — It Comes Down to One Question.
Who owns the design. If you do, it is OEM. If we develop it together, it is ODM. Everything else — the order size, the tooling, the lead time — follows from that answer.

The path
A Certificate Is the Last Step,
Not the First Claim.
The Australian file is followed here from application to marking, because every stage of it is on this page. The other two markets run the same shape through their own bodies.
- 01
Application and Test Programme
The configuration is submitted and an application number is allocated. AGA set the test programme against the standard before any testing began — for this file, AGA application 20295.
- 02
Independent Laboratory Test
An accredited laboratory tests the submitted sample against the standard. This file was tested by CCIC-CSA International Certification Co., Ltd. in Guangzhou, accredited to ISO/IEC 17025 under accreditation number TL-464.
- 03
Sample Modification and Re-Test
Where a test requires a change, the sample is modified and re-run rather than argued past. This file records a modified exhaust outlet and a mesh wind barrier fitted at the bottom before the tests passed.
- 04
Review and Certificate
The scheme reviews the report and issues the certificate if the results stand. AGA recorded the results as satisfactory with no further assessment required, and issued certificate 9358.
- 05
Production Audit
The certificate is not the end of the obligation. AGA require a Product Verification Audit — arranged when the first production batch is ready. For this file that audit is outstanding.
- 06
Marking Before Supply
Nothing ships before the unit carries its marks. AGA require a Maker's Warranty Badge or an AGAMark under licence, plus the Gas Compliance Mark, on every production unit.
The certifying body's condition on the mark
CSA make the certificate conditional on a production test plan run at the factory and documented for their field services representatives. These are CSA's conditions on the mark, not our own line controls — how the line itself is gated is on the quality control page.

Certification Attaches to the Configuration That Was Tested
Certification covers the configurations listed above and nothing else. A model outside them is not covered, and a change to a covered one re-opens the file — which is why the alterations record sits below. What applies to your order is confirmed in writing.
Our position on certification claimsThe tested configuration
A Live File Records What Changed,
And Closes It.
Certification tests a specific build. When the build changes, the file records the change and the unit is re-tested before the certificate stands — including when a test fails first.
Sample Modification
The submitted sample was recorded with a modified exhaust outlet and a mesh wind barrier at the bottom — the change the wind test required. The tests were then passed.
Resolved before issueIgnition Period
The delayed ignition test failed because the flame flashed out of the appliance. The ignition period was changed from 4 seconds to 1.5 seconds, and the report records the alteration.
Resolved in edition 1Why We Publish This
Every certification file accumulates notes like these. A file that shows only the passes has been summarised; this one records the change and the fix together, which is the only form in which it is useful to a buyer.

After delivery
Who Carries What,
Once the Container Lands.
A fault in the field is shared work. Naming which side owns which half of it before the first case is raised is what keeps a claim from turning into an argument.
| The area | Gulfstone carries | The brand owner carries |
|---|---|---|
| The unit | The assembly as it was produced and packed, held to the record that shipped with it. | Fitting it, the gas and water connections, and the first start in the field. |
| The part | A component picked from the serviceable line and shipped to your market. | The service-bay time and the engineer who fits it where the unit actually is. |
| The diagnosis | A cause named in writing, with the evidence behind it — not a holding reply. | The end user’s point of contact, and the retail returns and replacement desk. |
| The paper | The production and test evidence behind the unit, if a case turns on how it was made. | Local labelling, documentation and the obligations that sit on the brand in that market. |
The split is written into the supply agreement before a program starts, rather than negotiated one claim at a time.
The case
One Case Record,
From the Report to the Fix.
Every fault opens the same file, whatever it is. Nothing runs through an email thread — the file is the thread, and you, we and your service partner all read it.

Raised
A retailer or end user reports a fault upward. You send the serial number, a photograph and the order number. No form and no account are needed to open a case — the evidence is the application.
The day it reaches you
Acknowledged
A named person at the desk takes the case and replies with its number — an answer from someone who has read it, not an automated receipt.
Inside the response window
Triaged
We separate a fault in the build from a fault in installation or handling, and both from a component that has simply reached the end of its life. The three are answered differently.
Once the evidence is in
Dispositioned
A replacement part is picked and shipped, or the unit is replaced, or — where the case points at a production run — the fault is logged against that batch rather than against your order alone.
When the cause is named
Closed
The file closes with what was changed and why, so the correction reaches the next batch instead of being rediscovered on it.
When you confirm the fix
The file reads the same whichever way a case closes, so a claim and a refusal are both visible in writing.
Routing
What Reaches
Which Desk.
Most cases close at the first desk. The rest move up a fixed route rather than being re-explained from scratch each time — the file travels with them.
A component that has failed on a unit in service.
The Service Desk
Where every case opens and where most close: a part identified against the model, a price and a shipment.
A fault that repeats across units, or names a model.
The Product Engineer
The engineer who set the build reads it against the production record for that run.
A claim that a unit fails the figures it was published with.
The Test Lab
The part or the unit is re-run on the equipment that qualified it in the first place.
A fault traced to a batch or a component lot.
The Line
The finding goes back to production and to the suppliers behind that batch.
A single unit and a hundred follow the same route. What changes is how many people read the file, not the path it takes.
Serviceable parts
Built to Be Repaired,
Not Written Off.
The components a service bay replaces most are designed to come out of the unit. Each sits on a priced spares list attached to your program, so a repair can be priced without a factory email.
| Part family | Replaced when | Ships as |
|---|---|---|
| Igniter and controller | A unit will not start or will not hold a flame | Field-changeable module |
| Gas valve and regulator | Output drifts, or the valve will not seat | One changeable group |
| Heat exchanger | The part a service centre reorders most | Core assembly |
| Seals, gaskets and o-rings | Any service opening of the gas or water path | Consumable set, stocked |
| Door, panels and fittings | Transit or field damage to the outer unit | Individual panels |
The list goes out with the order, so your service partner can price a repair without a quote going back to the factory.
Within the market
What a Service Partner
Gets to Work Without Us.
A brand owner running several markets cannot route every repair through Foshan. This is what a local repairer receives so first-line service happens where the unit is.
Packing list
- A priced spares list — every serviceable part with its program price, so nothing waits on a quotation.
- A service manual — an exploded parts view and the replacement procedure for each component on it.
- A diagnostic sheet — the checks a repairer runs first, so a unit is only returned when it needs the factory.
- A cover table — what a warranty case covers and what a service-life part does not, written plainly.
- A named contact at the desk, and the case file that the repairer and the brand owner both read.
Assembled when the program is set up, not after the first fault has to be handled without it.

Each one is a job a buyer is already doing. Pick the one that matches your line — or tell us the job and we will scope the build around it.
Camping Shower Programs
A portable, bottle-fed shower unit for basecamp, overland and job-site washing. Built to your market, your brand and your carton — the platform the camping line is already shaped around.
Explore scenarioOverland and Expedition Shower Systems
A shower built into the vehicle rather than strapped to it: braced for constant vibration, shipped as one standard kit, and locked to a single specification across several markets.
Explore scenarioOff-Grid Cabin and Outbuilding
Wall-mounted, bottle-fed hot water for cabins, outbuildings and agricultural utility rooms. No mains power, no plumbing run — a unit built for a building that was never wired for hot water.
Explore scenarioRV Private Label and Fitment
Tankless RV water heaters built to your cut-out, the electrical scheme the vehicle carries and your destination market, under your brand. A drawing question answered at the factory rather than a catalogue selection.
Explore scenarioPool, Farm and Site Wash-Down
Bottle-fed hot water for outdoor rinse and wash-down points — pool surrounds, livestock and dairy stations, yard and equipment washing. Built for a point that has no supply and no supervision.
Explore scenarioHow it works
Three Steps.
No Runaround.
Every scenario runs the same way, from the first message to the container. One team carries it, so nothing is lost in a handoff.
Tell Us the Job
The vehicle, the site or the pitch. Where it is used, who uses it and what the market is. That is enough to start — no drawings required to have the first conversation.
We Scope the Build
The lab maps your scenario to the right platform and returns a plan: what moves, what stays standard, and what the certification scope is for your market. No black boxes.
We Build and Ship
Once you approve, the line is set. In-line checks run through the run, and third-party inspection is welcome at any gate. One contact from tooling to the container.
Who this is for
Built for the Buyers
Who Sign the PO.
Not a catalogue shopper. Every scenario on this page is written for a professional who has to justify the order, the fitment and the certification.
RV and Camper OEM
Engineering & purchasing
You build the vehicle and the unit has to match the bay you already have. Cut-out, 12V scheme and market certification are the conversation, not colour options.
Importer and Distributor
Sourcing & category
You carry the range into a market and answer for what lands. The gas setting, the certification scope and the spares line decide whether the season goes well.
Outdoor Retailer
Buying & private label
You need a branded line that sells through and a supplier who will not put a SKU you own onto a competitor shelf.
Hire and Fleet Operator
Operations
Your units are used hard by people who did not buy them. Housing, spares and a priced repair list matter more than the spec sheet.
How to judge a supplier
Six Questions
Before You Shortlist.
Every buyer who has to take a water-heater programme to an internal review is asked the same six questions. Each row below names the question, the evidence that answers it, and where to find that evidence here.
Duty cycle
Is this unit carried to a site, installed in a vehicle, or fixed to a building?
The mounting architecture and the shock or vibration specification, matched to where the unit actually lives.
Fuel and site
Is there mains power, a plumbed feed, or neither where the unit is used?
The ignition source and the water feed, stated as an install condition rather than an accessory.
Market files
Which markets must this one product be legal to sell into?
A separate document per market, each naming its own standard and its own covered model list.
Gate record
What stops a bad unit before it reaches the container?
The checks, their sampling levels and the records filed against a serial number.
Service side
When a unit fails in the field, who owns the fault and what can be replaced?
A written responsibility split and a priced parts line, agreed before the first order.
Programme path
Can we start with a sample, or does the first order have to be a container?
A documented ramp with a decision point at each rung, so a small first order stays possible.

How the platform answers
There Is No Mains Power at the Pitch
Ignition runs off the unit's own pack — no wiring, no hook-up, no generator

Where This Build
Actually Goes.
The same platform against three different jobs. What changes between them is where the water comes from and who is drawing it — not the unit.

Basecamp Shower and Dishwash
A shower and a sink off one bottle, run in turn before the light goes.
Overland

Crew
Job-Site Hand-Wash Point
One unit covering a crew wash station, drawing off the site bottle.
Pool heating is a different duty to a wash point — a pool has to be held at temperature against the whole body of water, which these units are not built for. What they do is supply hot water to a rinse or wash-down point. Tell us the duty and we will tell you honestly whether the platform fits it.

The challenge
Three Buyers, Three Ways
The Line Is Judged.
A camping shower line is opened by three different buyers, and each carries a different risk into a first order. The program is opened against all three.
Camping and Outdoor Retail
Category buyer, seasonal camping line
A launch window missed is a season that cannot be recovered.
The shelf slot goes to the line that landed on time.
The build is set to the destination market and the launch window before the order is placed.
What changedThe unit on the shelf is the unit that was signed off.
Hire and Rental Fleets
Fleet manager, regional hire
A hire unit earns nothing while it is off the road.
Every unit in the workshop is a booking lost and a customer held at the counter.
The build is specified for a unit that is worked, not shelved, so it stays on hire rather than in the workshop.
What changedA hire unit that stays on hire.
Outdoor Trade and Distribution
Purchasing, outdoor trade distribution
A distributor commits to a line before the market has answered it.
A season that does not move is a warehouse bill and a lost slot.
The first build is scoped against demand you can already see, not against a forecast.
What changedThe reorder is written on what sold, not on what was promised.
What a program decides
What Goes in the Kit,
Settled Before the First Run.
A camping shower is a kit, not a box with an appliance in it. These are the decisions a program settles early — and the ones a first order tends to get wrong.
The platform
Which Build Carries the Line
One build in the range becomes the program SKU, and what stays standard across it. Everything else in the kit is decided against that choice.
Gas side
Regulator, Hose and Setting
The connection and the gas setting follow the destination market. Set at the factory, not adapted after the container lands.
Water side
Feed and Discharge
How water reaches the unit and what it discharges through — a bottle, a container, or a hose where a supply exists.
Carry and mounting
How It Travels and Sits
A portable housing is carried, not installed. Handle, bracket points and the case it ships in are part of the decision.
Spares line
What a Service Point Reorders
The parts a repair actually needs, held on a priced list behind the program so a service centre can quote without a factory email.
The fit
What the Pitch Asks,
And What Answers It.
The numbers belong to the product pages. This is the part that decides whether the platform suits the job at all.
There Is No Mains Power Where It Is Used
Ignition runs off the unit's own pack — nothing to wire, no hook-up, no generator.
It Travels in the Same Bay as the Rest of the Kit
A portable platform with a handle and bracket points, built to be carried rather than plumbed in.
Several People Wash in Turn, Off One Bottle
On-demand heating, so the water is hot when the tap opens rather than sitting in a tank.
The Unit Lands at a Pitch, Not at a Bench
A weather-rated, portable housing built for outdoor use and transport, not a sheltered install.
The Line Has to Hold Up Across a Season of Returns
Housing and fittings chosen for how the unit is actually carried and dropped, not only how it reads on a sheet.
When it is not the line
Where a Portable Shower
Is the Wrong Build.
A portable platform is carried, not installed. Where the job needs a fixed unit, a plumbed feed or a braced vehicle mount, the answer is a different programme on this site — not a heavier carton.
Vehicle Builds That Need a Fixed Mount
A unit bolted to a chassis for the life of the build is a different bracket, a different vibration specification and a different kit.
The vehicle-mounted programmeBuildings That Want a Wall Install
A cabin, outbuilding or site office with its own mounting wall and a plumbed feed wants a housing designed to sit there permanently.
The off-grid building programmeLines With No Retail Pack to Sell
If the unit is specified as a component inside someone else's product, the shelf face, carton and manual work more than the platform.
Component-level OEM
The season
A Camping Line Runs to a Season,
Not to a Purchase Order.
A shower program is planned backwards from the launch window. Every stage below exists to protect that date — and the checks sit inside the run rather than after it.
Season Brief
Brand, price tier, destination market and the week the line has to be on shelf. Enough to scope the SKU — no drawings needed to open the conversation.
Sample and Sign-Off
The build is approved on a physical sample before the line is set, so what is signed is what the run copies.
Tooling and First Run
A platform SKU with your branding and pack, or a private mould where the program calls for one. Then the first production run.
Checks Through the Run
Checks run inside production rather than at the dock, and third-party inspection is welcome at any stage of it.
How the quality system works
Booked to the Window
Documentation and freight booked against the launch date, so the line arrives in one shipment and one window rather than chasing the season in part-loads.
Destination builds
The Market Decides
More Than the Plug.
Gas, the pack and the certification scope all follow the market the line sells into. Tell us where it lands and the build is set from there.
Australia & New Zealand
One Build, Both Islands
Gas and the retail pack are set for the Australian and New Zealand market, so one build carries the line across both.
Gas setting for the destinationPack and manual in market languageCertification scope mapped first

The European build carries its own gas setting and its own documentation set for the market it is declared into.

It Has to Sell Off a Shelf,
Not Only Survive the Freight.
A camping shower competes in the aisle like anything else in the outdoor planogram. The pack is part of the program, not a courier decision.
The Carton
Built to take the freight it will actually meet, and to hold its shape on a pallet and on a shelf edge.
The Shelf Face

The kits
What Each Kit Contains,
And the Line It Belongs To.
Three lines ship as a kit. Each is packed to the platform it serves, so one line item on your purchase order carries everything the installation needs.
These are the parts that travel with the kits — the range carries more. The full accessory list is below.
Water intake kit
Camping and portableA draw from a tank, a drum or a jerry can rather than a mains supply.
- 12 V submersible pump
- Silicone pump hose
- Self-locking water quick-connect
A quick-connect at the unit water inlet.
The pump is submerged, never run dry, and draws clean water only — a lake or a river will scale the impeller.
Shower kit
Every platformThe hot-water end of the line, on every platform in the range.
- Combination line clip
- Self-locking water quick-connect
- Multi-function shower head
- Silicone shower hose
A quick-connect at the unit water outlet.
The shower stays open while the unit runs, so the controller keeps reading flow and the burner stays lit.
5 L installation kit
5 L fixedA fixed installation where water arrives under pressure rather than from a pump.
- Pressure-reducing valve
- Shower assembly
- Pump assembly
- Cigarette-lighter charging cable
- Alligator clips
A regulator on the cylinder and a valve at the inlet.
A pressure-reducing valve is mandatory on this line. Pressure straight into the inlet is outside the unit rating, and the valve is what keeps it inside.
At the cylinder
Which Gas Source
A Kit Opens Up.
The camping platform is rated on more than one gas. The accessories are what change the canister it will take, and each one has a destination it belongs to.
1 lb propane canister
No adapterClamps to the regulator directly and stands upright beside the unit. This is the default the camping platform is built around, and the one the regulator setting assumes.
High-altitude canister
Conversion adapterThe adapter in the kit steps the canister to the regulator. This is the mix the platform is rated on where the standard canister stops performing, and the adapter is the only difference between the two.
LPG — a domestic cylinder
Conversion adapter and hoseThe same adapter carries the larger cylinder to the regulator. This is the route the 5 L fixed installation takes, where the cylinder lives outside the wet zone and the run to the unit is a hose.
RV retrofit
A Door Panel for the Opening
Your Vehicle Already Has.
A replacement heater has to close the hole the old one left. The panel line runs in three sizes, because the openings in the field are not all the same.
Tank-style heaters dominated this wall for years, in 6, 10 and 12 gallon sizes, and most conversions today start from one of their openings. Our factory panel blanks a 6 gallon cut. The wider cuts needed two more sizes, which is why the line runs in three.
Panels are finished in the same powder coat as the unit and carry the same ventilation louvre, so a retrofitted wall reads as a factory fit rather than a conversion.
6 gallon cut15 × 15 inThe factory panel.
10 gallon cut15 × 18 inWide.
12 gallon cut18 × 18 inThe largest of the three.
The cut-out table ships with the panel. Measure, send the opening, and we match the size.

Where it goes
Four Buildings That Were Never
Wired for Hot Water.
The platform is the same. What changes is the building it hangs on, where the bottle has to stand, and how long it sits empty.
Short-Let Cabins and Lodges
Guests draw hot water on arrival and the building sits empty between them. One unit per cabin, no shared plant.
Workshop and Outbuilding
A shed or a garage used year-round, where the wash-up point matters more than a shower does.
Farm Utility Room
A building at the end of a track with no service run to it. A bottle is already on site; a mains connection is not.
Seasonal Shelter and Site Hut
A hut that opens for a few months of the year and is closed for the rest, at the end of a track rather than a road.
What the building demands
The Site Sets the Brief,
The Builder Answers It.
No spec sheet here — the figures belong to the product pages. This is the part that decides whether the platform suits the building at all.
Bottle-fedBattery ignitionOutdoor-rated
An outdoor wallNo mains powerNo plumbing run
It Mounts on an Outside Wall, Exposed to Weather
The housing is designed for that wall rather than tolerated on it — an outdoor position is the intended install, not an indoor unit that has been moved outside.
Still on the wall after the season that tested it.
The Cabin Is Empty for Months at a Time
Lighting is on demand and there is no pilot left burning, so the unit sits cold until it is asked for hot water — whatever the gap between visits.
Ready on the first visit, not after one.
No Service Run Reaches the Building
A mains connection and a plumbed feed are both absent, and neither is required: the ignition carries its own supply and the water arrives by container or hose.
Nothing brought to the site to make it work.
It Is Used by People Who Did Not Install It
Lighting and running the unit is a single gesture a guest or a contractor can be shown on arrival, with no panel to set first.
Hot water without a briefing.
When it is not the build
Where a Wall-Mounted Unit
Solves Nothing.
The platform is built for a fixed wall with no service run. A brief that needs something else should be routed to the programme that answers it.
Dwellings That Are Occupied Year-Round
Continuous occupancy with a mains supply and a plumbed feed is a domestic installation, not an off-grid one — the constraints this housing answers do not apply.
Sites Needing a Tank or Stored Volume
Where the brief specifies a cylinder or stored hot water rather than on-demand heating, the platform under the housing is the wrong one.
Tank and vehicle platformsBuilds That Move
A unit that travels needs a bracket and a vibration specification, not a wall mount, however similar the heating side looks.
The vehicle-mounted programme
What a program settles
Four Decisions,
Closed Before a First Run.
A cabin program is decided long before it is quoted, and the questions are about the site rather than the unit. These are the four that come up on every one.
- Fixed at survey
The Draw Points
A shower and a wash-up sink off one supply is the normal cabin arrangement. How far they sit from the unit decides the run and the fittings.
- Fixed at survey
The Mounting Wall
Which elevation the unit hangs on, how it is fixed through the cladding, and how much weather it actually takes on that face.
- Set by the site
The Supply Position
Where the bottle stands, and how far it has to be carried to the point of use — which decides the hose run as much as the unit does.
- Set by the site
The Off Season
How the unit is shut down when the cabin closes, and what has to be true of it before the next arrival.
Brief to first container
From the Site Survey
To the First Shipment.
Every stage closes on something concrete rather than a promise, and the checks sit inside the run rather than gathered at the dock.

The off season
The Season It Stands Empty
Is the Season It Is Judged On.
A cabin is not a house that goes quiet. It is a building with no heating in it for months, and whatever holds water inside it has to come through that on its own terms.
The Tank That Splits
A stored body of water is the part of a cabin hot-water system that fails over a hard winter, and it fails quietly — discovered at the first let of the season rather than in January.
The Service Call Nobody Wants
A cabin is reached by a track, not by a road. Anything that needs draining, refilling or recommissioning before a let turns one arrival into two.
What Comes Through Instead
A unit with nothing held in it has nothing to freeze. The off-season question becomes what you do at shutdown rather than what you repair in spring.

Who this is for
The Vehicle Decides
Which Question Comes First.
Where the unit lands in the build decides who is asking. A line, a retrofit and a parts counter arrive with three different drawings, and the first question is never the same one.
01
Travel-Trailer and Camper Lines
The unit is designed into the vehicle, so the recess is set before the first order and every unit that follows has to match it.
Opens withWhere does the unit sit in the wall, and what does the door have to clear?
What changedThe recess is right the first time.
02
Motorhome Retrofit and Replacement
The unit has to answer a recess that already exists — one the incumbent fit, and one the vehicle was built around.
Opens withWhat is in the bay now, and what does the new unit have to match?
What changedNo bay rebuilt to take the unit.
03
Aftermarket and Service Stock
The unit is held as stock and fitted by someone who did not build the vehicle, so the fitment and the parts have to stand on their own.
Opens withWhat does the fitter need in the box, and what is stocked behind it?
What changedA fitter has what the fit needs, without calling us.
When it is not a vehicle program
Briefs That Do Not Belong
in a Vehicle Recess.
The programme is built around a recess, a 12V scheme and a vehicle that already exists. A brief without those constraints is better served by another build on this site.
Units Carried From Pitch to Pitch
A shower or heater that travels in a bag rather than a bay needs a handle and a carry case, not a recess and a door swing.
The portable camping lineFixed Building Installs
A wall, an outbuilding or a site office sets its own mounting and feed conditions, and none of them are a vehicle recess.

Send the recess and we will tell you plainly which half each item falls on — including the ones that are yours.
Getting started
It Opens on a Drawing,
Not a Catalogue Number.
Four moves, and the first one starts from something you already have.
Send the Recess
The opening you cut, or the one already in the vehicle. A sketch and the direction the door opens are enough to start.
We Answer Against It
The unit, the door assembly and the trim are checked against your recess, rather than the bay rebuilt around ours.
How a build is developedApprove on a Physical Unit
Sign-off happens on a sample you can hold, so what is approved is what the run copies.
The Run Repeats It
The approved reference is what every unit after it is held to — which is the whole point of approving one.
See the unit it is built on
Inside
The Unit Goes into a Room
Someone Else Laid Out.
A vehicle interior is designed around the bed, the galley and the dinette long before a water heater is specified. The recess has to find its place in what is already there.
Galley
Under the Counter Run
The services a kitchen already brings to one wall — which is where the unit usually wants to sit.
Dinette
Behind the Seating
The space under a bench or behind a squab, where a recess is easiest to hide.
Bed
Below the Sleeping Area
The locker run under a fixed bed, which is often the only full-height wall left.
The opening
The Fit Is Decided
At the Opening.
A door has to sit flush in a wall it was not cut for, swing past what is already there, and still be serviceable. That is the whole job of the assembly.
Door, Hinge and Latch
Approved as one assembly, so the swing clears what is mounted beside it.
Trim Ring
Closes the gap between the unit and a wall it did not cut.
The Service Face
What a fitter reaches without dismantling the vehicle around it.
Where it goes
Built for the Places
The Vehicle Actually Reaches.
A camper is sold on where it can go. Whatever is fitted into it has to work at all three of these without a service call.
A Pitch With No Supply
Where the water comes from a container, not a plumbing run.
A Roadside Stop
Used once, in passing, and expected to light first time.
A Site With No Power
Where the only supply is what the vehicle brought with it.

Solution · Pool, farm and wash-down
Outdoor Wash-Point Water Heaters,
For Points With No Supply.
A rinse before entering the water. A dairy or livestock wash-down. A yard where a crew or a fleet is hosed off. None sits near mains power or a plumbed feed, and each is used by people who did not install it. The platform is built around that, not around a bathroom.
Before anything else
One Thing This Platform
Does Not Do.
The question a pool owner asks first is the one worth answering first, because the answer decides whether the rest of this page is even relevant to you.
What it is
A Wash Point, Supplied
Hot water arrives at the point of use — a shower head, a wash-down lance, a rinse tap — drawn on demand and heated as it is drawn. There is no tank at the point and no stored body of water to hold.
What it is not
A Pool, Held at Temperature
A pool has to be held warm against its whole volume, and that load does not shrink with the pool — a small plunge pool or a hot tub is the same duty as a large one. Holding a body of water at temperature is a different job, and it is not this one.
Where the water is needed
Three Wash Points,
One Build Behind Them.
Every point here shares the two conditions that decide the build: nothing is run to it, and nobody is watching it. What changes is the duty it is drawn for and how hard it is used.
Rinse Before the Water
A hot rinse point at the edge of a pool, so a swimmer rinses before they enter rather than after. It stands where a plumbing run was never taken — beside a filter plant, a changing block, or a private pool with no building at all.
Draws
A short, hot rinse at the water’s edge
Cadence
Seasonal — heavy on the days the pool is open
Must survive
Chlorine in the air and salt on the fittings
A pool open on the day it was meant to be.
A Wash-Down in a Shed With No Supply
A dairy, a parlour or a livestock shed where the wash-down point matters every single day and the building was never plumbed for hot water. One unit holds the point; the herd sets the tempo rather than a season.
Draws
A daily wash-down, drawn in bursts
Cadence
Daily and year-round — it does not close
Must survive
Mud, muck and a hose left running
The wash-down starts on time, every morning.
The Wash Bay at the End of the Yard
A depot or a yard where a tractor, a ute or a whole fleet comes back dirty and the crew rinses it down before it is put away. The point moves with the work, so the run to it is part of the decision.
Draws
A long, high-volume rinse, vehicle after vehicle
Cadence
In bursts, whenever the kit comes back dirty
Must survive
Grit, impact, and a hose dragged across it
A bay that clears without a second pair of hands.
When it is not a wash point
Where a Fixed Point
Is the Wrong Answer.
A wash point is fixed, supervised by nobody, and sized to a site. A brief that moves, or that serves one household, is a different programme on this site.
Units That Travel With a Vehicle
If the water has to go where the vehicle goes, the unit needs a bracket and a vibration specification rather than a permanent site position.
The vehicle-mounted programmeSingle Dwellings and Guest Cabins
One building with one wall and its own feed is an off-grid install, not a site wash point with three repeated positions.
The off-grid building programmeRetail Lines Sold Off a Shelf
A unit bought by a consumer and carried home needs a carton, a shelf face and a consumer manual, not a site installation plan.
The portable camping line
What it has to survive
The Same Weather Is
A Different Problem at Every Point.
A wash point is outdoors and unsupervised, and what that costs it depends on where it stands. Read down a row to see one condition across all three; read across to see one point against all five.
| Load case | Poolside | Livestock & dairy | Yard & fleet |
|---|---|---|---|
| Chemical exposureWhat is in the air and on the fittings. | Chlorine in the air beside a treated pool | Disinfectant at the parlour wash-down | Detergent and traffic film at the wash bay |
| Grit and muckWhat comes back on the hose and the hands. | Sand off wet feet in the changing area | Mud and slurry through the shed daily | Road grit and mud off every vehicle |
| Weather and UVWhat the housing stands in, year after year. | Full sun and salt air on an exposed surround | Wind and rain through an open-sided shed | Open yard with no shade over the point |
| Unsupervised useWho works it, and whether anyone is watching. | Swimmers and guests, no operator present | Herd staff on a routine, one-handed | A shifting crew across every shift |
| Cold and drain-downWhat happens to the point when it is not in use. | A point that closes when the season ends | A point that runs every day of the year | A point idle overnight, hard-frost mornings |
One source, every point
The Whole Problem Is
The Distance, and the Quiet.
A wash point is rarely next to the thing that feeds it, and it is never watched while it runs. Place the source once, and the taps off it can sit anywhere the work is.
At the sourceOut where the point is
The Source
One unit on the wall or on a stand, with the bottle beside it. This is the only point on the site that somebody visits on purpose.
The one visited point
The Nearest Tap
The point closest to the source, where the run is short and the faucet could not be simpler if it were plumbed.
A few steps awayUnattended
The Far Tap
The point the run does not reach on its own — a second shed, a far end of the yard. Reach, not the unit, is what decides whether it is served.
Across the yardUnattended
The Moving Point
A point that has no fixed home: the wash bay that shifts with the work, or the second site that opens next season. The unit is the only part that has to move.
No fixed homeUnattended
How the point is used
One Point Opens for a Season.
The Other Never Closes.
A poolside rinse and a dairy wash-down are the same build answering two different working lives, and the difference is not in the unit — it is in how often the tap is opened.
A Point That Opens and Closes
Seasonal — opens and closesThe poolside rinse runs hard while the water is open and stands idle for the rest of the year. It has to survive its own quiet — a point that is used for part of the year cannot need recommissioning before the part that matters.
A Point That Runs Every Day
Daily — never closedThe dairy or shed wash-down is opened every morning and often through the day. It has to survive being worked rather than being left — the wear is in the routine, not the weather.
Neither point is a harder build than the other. They are the same unit answering two different working lives, and the program is set against whichever one your site actually runs.
Starting an enquiry
What a Quote Needs
From Your Side.
Nothing here needs a drawing to open a conversation. These are the six things only you can tell us, and the first reply is scoped from them.
The Duty
What the point is for — a rinse, a wash-down, a hose-down bay — and roughly how long it runs each time it is used.
Where the Point Sits
Beside a pool, in a shed, at the end of a yard. Whether it is under cover, and what is in the air around it.
The Distance from the Source
How far the point is from where a unit and a bottle can reasonably stand, and whether that run is fixed or moves with the work.
How the Point Is Fed
Whether there is any water at the point already — a tank, a trough, a standpipe — or whether it has to arrive from a container or a hose.
The Destination Market
Where the line will sell and be installed. The gas and the certification scope are set by the market before anything is quoted.
Your Brand and Volume
The name the line carries, whether it starts from a build that already exists or needs its own, and roughly how many points a year.

The buyers
The Buyers This Program Serves
Four types of buyer, one requirement: the shower is a part of the vehicle, not an appliance strapped to it. Each arrives with a different job and the same non-negotiable.
Conversion and accessory
Overland Conversion and 4×4 Accessory Brands
They sell the shower beside suspension, awnings and storage, so the bracket pattern and the fixing points have to match what the workshop already builds. The unit leaves the shop as part of the vehicle, not as a box in the back.
Expedition equipment
Expedition Equipment Brands
They build a complete shower kit for long-distance travel, and their customers cross borders. The gas source and the compliance file have to follow the route rather than the factory default.
Systems integration
Vehicle Systems Integrators
They fit the shower into a vehicle another team designed. What matters is that the interface repeats: one fitting set, one mounting pattern, and service parts that can be replaced one at a time.
Multi-market brand
Brands Selling Into Several Markets
One product line for Australia, North America and Europe. They do not want a different supplier for each destination, and they do not want three build files to keep in step.
The challenge
The Road Is Where the Build Is Judged
The road, not the campsite, is where a vehicle-mounted build fails. Vibration does not announce itself — it works on the housing, fittings and bracket until something gives, usually after the container is paid for.
Shell, fittings, bracket
The unit is built to be carried, not to stay fixed.
Corrugation and washboard load a portable housing in a way a campsite never does. Corners crack, quick-connects creep loose and the bracket bends, so units arrive damaged or fail within weeks. The return and the review both land on the brand that sold them.
Markets
Every destination reopens the gas setting and the compliance file.
Australia, North America and Europe do not share a specification. Each change reopens the order, delays the launch and leaves several versions of the same product in the warehouse, each with its own paperwork.
Accessories
The pump, the fittings and the bracket are sourced separately.
Mixed parts produce compatibility failures and blur who owns the fault. A leaking joint becomes a dispute between three suppliers, and the brand pays for it in returns, replacements and customers who stop trusting the listing.
Mounting
A portable unit does not sit still on a vehicle.
Without a fixed bracket and a mount that matches the build, the shower reads as an afterthought. The customer who bought a finished conversion sees an appliance strapped in, and the brand loses the professional position it was selling.
Suppliers
Shell, parts and certification come from different vendors.
A reorder arrives close to the last run rather than identical to it. Customers notice the drift, the brand absorbs the complaint, and the program loses the one thing it was built on: the same product, every time.
The build
The Build Answers the Road
Every failure above is answered inside the platform, not by an accessory added after the container lands. From the shell and bracket down to the specification a reorder is built against.
Shell and bracket
Braced for the Track
Housing and bracket are reinforced for continuous vibration, with the mounting points carried through the shell rather than bolted onto it. The assembly is specified against the vehicle it will ride on, not against a generic rack.
Fittings
Locked Against Vibration
The water side uses positive-lock connections, so joints do not creep loose between services. The fitting set is matched to the kit it ships with rather than drawn from a general-purpose catalogue.
Kit
One Set, One Carton
Pump, hose, fittings and bracket travel in the same carton as the unit. Compatibility is settled at the factory, so the buyer is not assembling a working system from three suppliers after delivery.
Mounting
Two Ways to Fit
A vehicle-mounted version for conversion and accessory brands, and a portable version for buyers who sell on the move. The difference is the bracket arrangement, not the platform underneath it.
Specification
Written Once
The shell, the fitting set, the kit line and the destination files are written into one program reference when the first order is confirmed. A reorder is built to that reference rather than to a new reading of the brief.
The markets
The Platform Stays Locked, the Market Files Change
One platform carries every destination, and only the market files change after the first order. The table below says what is fixed and the one thing a destination still sets.
Fixed before the first run
Shell and bracket
One housing, one mounting pattern, every market.
Fixing set matched to the vehicle build.
Fitting set
The water side and the kit line do not change at the border.
Nothing — the fittings travel as they ship.
Reference file
One program reference sits behind every order.
Gas setting, compliance file and manual language are written into it per destination.
One Build Across the Tasman
Long tracks, remote camps and heat that does not let up. The shower is sold as part of a touring build, and the customer fits it before the first trip.
What the market changes
- Runs from the cylinder already on the rack
- One fuel source for the touring build, not two
What the buyer has to hold
- Serviced in any state without re-checking the build
- One reference file travels with the vehicle
Built to the North American File
Conversion shops and expedition outfitters list the shower beside suspension, awnings and storage. The unit is judged as part of the vehicle, not as an add-on to it.
What the market changes
- Cylinder connection follows the workshop’s fittings
- Plumbs into the build rather than beside it
What the buyer has to hold
- Unit handed over already documented
- No paperwork chased after the sale
A Separate File, the Same Platform
Alpine passes, wet cold, and vans built by converters who expect the fittings to match the vehicle. The buyer asks for the file before the sample.
What the market changes
- Documents in the languages the van is handed over in
- The marking a converter can show without translating it
What the buyer has to hold
- One country’s van sells into another
- No new papers for the unit
The result
The Buyer's Side of the Order Changes
A locked platform changes what the buyer does between orders, not what the brochure says. These are the changes that show up in the day-to-day.
Reorder
A repeat order is confirmed against one reference, not a fresh round of questions about the shell, the fittings and the files.
Shipping
The kit ships as one set, so compatibility is answered before the container is loaded and the liability does not split between suppliers.
Markets
A second destination adds a file rather than a second build, so the launch date is set by the freight instead of by re-engineering.
After-sales
Unit and parts share one specification, so a repair is a part replacement rather than a negotiation over which supplier owns the fault.
Listing
A conversion brand can list the shower as a vehicle accessory, and the customer reads it as part of the build rather than an add-on to it.
Which line you need

The fit
Who This Program Fits, and Who It Does Not
This program fits brands selling the shower into a vehicle or across several markets. It is a poor fit where the shower is an occasional campsite accessory and nothing else.
A fit
Overland conversion and 4×4 accessory brands
The shower is sold as part of a vehicle build and needs a fixed bracket.
Expedition equipment brands
The kit travels across borders and has to be set for more than one market.
Vehicle systems integrators
One interface, one mounting pattern and parts that can be replaced one at a time.
Brands selling into several markets
One platform for Australia, North America and Europe, with files swapped per destination.
Not a fit
Retail camping lines with no vehicle fitment
The pack, the shelf face and the carry story matter more than a mounting bracket.
Single-market buyers with no locked-kit requirement
A one-destination line rarely earns back the work of freezing a platform.
Buyers shopping each component separately
If the unit price is the only variable and parts are sourced one by one, the kit is working against the brief.
Lines re-specified every season
If the fit, the finish or the kit changes at each launch, a locked reference is structure the line does not need.

Market presence
A Visible Presence for the Market You Serve.
A distributor should not have to design every customer touchpoint from zero. The Gulfstone visual system gives you a foundation that adapts to the approved range, your premises and your market.
A Retail and Showroom Concept You Can Localise
Carry one recognisable identity across the exterior sign, the product display zones and the customer consultation area. The final layout is adjusted to your premises, your local requirements and the families you chose to stock.
- Facade and signage direction
- Product-wall zoning by family
- Consultation and sample areas
An Exhibition Foundation That Is Ready to Build
Start regional trade exhibitions from a consistent environment rather than a blank floor plan. Product displays, demonstration space and partner conversations stay connected while the final structure is reviewed with your venue and contractor.
- Modular product presentation
- Reception and meeting zones
- Contractor-ready design direction
The handover
One Identity Across Every Sales Conversation.
The system continues after a customer leaves the store or the stand. A coordinated partner kit keeps technical follow-up clear and the identity recognisable across print, samples and digital presentations.
Approved Product ListThe exact models, ratings and fittings you are carrying, locked as the reference for repeat orders.
Artwork PackageLogo treatment, carton and label artwork, colour targets and the print files your suppliers need.
Sample PlanWhich units go on the floor, the bench and the stand — and which stay boxed as reference stock.
Digital Presentation SetProduct imagery, specification sheets and listing copy formatted for your market and your channel.
Confirmed Partner HandoffApproved range, artwork package, sample plan and order reference — recorded together, so a reorder does not reopen the negotiation.
The sequence
From First Brief to Repeat Delivery.
A shared reference keeps the product, commercial and documentation decisions connected as the program grows.
- Share the Market Need
Tell us the market, the product families you can move, your target customer and what you want to lead with.
- Review the Product Route
Align the published range, the ratings, the documents and whether any part of the build needs to become yours.
- Confirm the Starting Scope
Agree the sample set, the first quantity, the commercial terms and the milestone that marks the start.
- Build the Order Reference
Record the approved products, artwork, packaging and documentation as the single reference everything reorders against.
- Support Repeat Supply
Use the confirmed reference for replenishment, range development and the follow-up that keeps a line selling all year.
Partner support
What We Can Coordinate With a Partner.
Support is organised around the range and the cooperation scope you confirmed — not a generic partnership badge.
- Product Selection
The published range, its ratings and its application fit, reviewed against your market together.
- Market Presentation
Store, exhibition and sales-material direction coordinated around the range you actually carry.
- Product Changes
Where a build has to change for your market, the scope is assessed and defined before anything is approved.
- Region and Terms
Where a market needs protection, the scope is written into the agreement — which families, which territory and for how long. Nothing is promised before that, and every market is discussed on its own.
- Order Follow-Up
Samples, the production reference, packing and delivery details kept aligned from the first unit to the reorder.
The first brief
Make the First Conversation Useful.
A concise brief is enough for us to tell you whether the right next step is range selection, a sample set, a development route or a project quotation.

- Product families and key ratings
- Customer type or application
- First order and expected annual volume
- Certification or document needs

Read the case fileWhat this proves
The Patterns Behind the Programs
Different markets, different platforms — the same four decisions underneath.
One Owner, One Standard
Consolidation lifts delivery only when one named owner holds the export calendar and one Incoterm standard covers every factory — otherwise the exceptions just move.
Plan the Load, Not the Order
Four suppliers are planned as one shipment against one cut-off — the fee stack collapses only if documents travel with the container.
Standardise the Platform
The spare-parts shelf is an architecture decision — one common module set across cabin sizes costs less than six brands of spares and the dispatches they hide.
Design for the Second Season
Coils, spares lines and frozen references are what decide whether season two is a reorder or a rebuild.

Most of what decides a gas appliance is settled before anything is built — on the drawing, at the cut-out, in the tolerance someone chose for the gas path. I have spent my working life on the manufacturing side of that decision, and this is where I write down what it has taught me.
Nothing here is written from a sales desk. Every note comes off the floor: a batch held until a reason was found, a fitting that failed in transit, an approval path that only made sense once the destination market was fixed. If you read these first, the opening conversation starts at the standard rather than at the beginning.
Areas of expertise
Where I Do the Work
The parts of a program I am usually the one to sit in on with a buyer, and what each one changes downstream.
Product and DFM Engineering
Reading a drawing for what will actually be hard to make — the cut-out, the gas path, the tolerance stack — before the tooling is cut rather than after.
Approval Scope, Set Early
Which approval a destination market requires is a decision to make before the build is fixed, not after: the answer reshapes the gas path, the labelling and the file pack that ships with the unit.
Private-Label Tooling
Shell and handle moulds, colour matched to Pantone or RAL, branded carton and multi-language manuals — a line that is the buyer’s own down to the box.
Supplier and Quality Systems
How a supplier is read before a program is placed, and how a standard is set and held through a run — the questions I ask on a first plant visit.
Working principles
How I Run a Program
Four convictions that hold across every build, whatever the product or the market.
Field First
A technical question is answered on the floor, not at a desk. The feedback a buyer gets comes from whoever would actually build the unit.
A Standard, Not an Adjective
Quality is a figure and a method agreed before the run — not a word on a purchase order. A target that was never written down cannot be met or missed.
Documented Handoffs
Nothing changes hands on trust alone. What was decided, by whom and against which spec travels with the program, from the drawing to the container.
Audit-Ready by Default
The record a buyer needs later is produced while the work happens, so the file is already there when the question comes — not assembled afterwards.
