Water heater kits and accessories

Outdoor water heater kits,
and the fittings that finish them.

A unit is only as usable as the fittings that arrive with it. We build the kit around each platform and quote it onto your program, so the load leaves us ready to install.

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.

Silicone water-inlet hose with the 12 V submersible pump and its quick-connect coupling
Silicone water-outlet hose with a blue self-locking quick-connect at one end
Multi-function shower head on its handle, teal handle with a chrome face and a flow switch
Two gas hoses coiled, each with a brass cylinder fitting on one end
Pressure-reducing valve with its brass stem and the diaphragm housing beside it
Gas cylinder adapter: a machined metal body with a threaded spigot at each end
Coiled charging cable with a cigarette-lighter plug at one end and a small two-pin connector and red lead at the other
Mains power adapter with its barrel connector and a separate mains lead
Pop-up shower tent, a green cubicle with a zip door and a peg-down foot

These are the parts that travel with the kits — the range carries more. The full accessory list is below.

Water intake kit

Camping and portable

A 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 platform

The 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 fixed

A 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 adapter

Clamps 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 adapter

The 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 hose

The 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.

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.

Optional

What else can travel
with the load.

Everything below is ordered alongside the units, on the same program. Take the whole list or take the lines your market asks for.

Cigarette-lighter charging cable

Charges the pack from a 12 V socket on the move.

Power adapter

Charges the pack from mains before the trip.

Magnetic shower seat

Holds the shower head against a steel panel, no drilling.

Lithium battery pack

4,000 mAh, on the platform the unit ships with.

Boost module

Holds the charge steady off a vehicle supply that sags.

Alligator clips

For a battery terminal rather than a socket.

Carry bag

Ordered at a higher minimum than the rest of this list — worth batching.

Portable bucket

The water container the intake kit draws from.

Shower tent

A cubicle, nothing more. Never ignite the unit inside it, and never let the flue discharge into it.

Customer reviews

What buyers say about the kits

Buyers who order the accessories on the same line as the units — a retail category buyer, and a dealership parts desk on the retrofit.

“The kit is what made the reorder simple.”

Everything the unit needs on the water side — the pump, both hoses and the shower head — arrives in the same carton as the heater, so nothing is short on the dock and nothing has to be sourced locally.

Three seasons and 4,000 units later, the reorder has come back identical every time, on the same PO as the heaters.

“The panel is the reason a conversion looks factory.”

Most units coming out of these walls are 6, 10 or 12 gallon, so the opening is never the same twice. Three panel sizes cover every one we have hit, and the cut-out table tells us which to order before we pull the old unit.

The finish matches the heater, so the wall closes clean — and the techs stopped trimming panels to fit.

Questions buyers ask

The questions before a kit order

Ordering a kit on its own, what changes by market, and what happens when a part wears out.

01Can I order a kit without ordering the heater?
Yes. Kits are quoted against the platform rather than against a unit, so a replacement pump, hose or shower can be ordered on its own. Tell us the model the kit is going onto and we confirm the fittings before it ships.
02Do the kit contents change by market?
The gas side does. The cylinder the unit connects to is set by destination, so the adapter and the regulator in the kit are matched to the market you are selling into. The water side — pump, hoses and shower — is the same everywhere.
03Is the shower tent a part of the kit?
No, it is ordered alongside it. It is a cubicle for the shower, not an enclosure for the heater, and it must never be used with the unit running inside it.
04Can the kits carry my brand?
Yes. Packaging, the carry bag and the printed material are all part of the same program as the unit, so the kit arrives under your brand rather than ours.
05What happens when a part wears out?
Pumps, hoses and shower heads are on the replaceable list and can be reordered against the same platform. The service side of that is handled after the container lands — the after-sales page sets out how a claim or a reorder is routed.
