Founder spotlight

The conviction
that built it.

A trading desk controls neither quality nor cost. A single-category factory cannot cover the accessories and fitment a program needs.

The complaint kept coming back: the heaters reaching the trail were built like accessories, not appliances — heavy to carry, short-lived once the trip actually depended on them. There was a better way to build one, and no factory was doing it.

So we built the plant ourselves and stayed on the manufacturing side. Three decades on, one conviction has not moved: build to the buyer’s drawing and market, and let them verify every claim on our floor.

Founder & CEO

Our approach

Engineers at the table.
Direct to the factory floor.

A gas appliance fails or passes on tolerances, gas paths and cut-outs — details a sales desk relays badly. The person who understands them is the person you reach.

01

Engineer to engineer · Reply inside 48 hours

Your product or plumbing engineer talks to ours. DFM feedback, cut-out reviews and tolerance questions stay technical, because the work is.

02

Outcome ownership

When something is wrong, the answer is not "we told the factory." It is a corrected batch and a prevention protocol, on our floor.

03

Bilingual on the ground

English-fluent engineers based in Guangdong. Nothing is relayed twice, and someone is on the line the same day.

What we run

One partner, one workflow.
No handoffs.

Accessory and component sourcing is not subcontracted to a trading layer. Each partner plant is audit-listed, and its output is inspected against our own documentation.

01

Owned manufacturing

Heaters engineered and produced on our own Shunde lines — control over tooling, materials, assembly and testing.

02

Audited factory network

Housings, accessories and components — vetted on lead time, price and quality record before a program is placed.

03

OEM / ODM & private tooling

Private shell and handle moulds, logo, colour to Pantone or RAL, branded carton and multi-language manuals.

04

Certification delivery

AGA, CSA and CE paths run end to end, with the test reports and declarations shipping inside the container.

05

Mixed container & cube

Heaters, shower kits and quick-connects combined in one load, with the carton sizes and cube worked out before the booking.

06

Four-gate QC

Incoming, sub-assembly, combustion and pack — each sampled to a named standard, with a plant audit on file.

What buyers say

Impartial quotes from the people who sign the PO — and what they say about the team behind the work.

“Our shelf presence is ours. Nobody else ships this shell.”

It shipped under our logo on someone else’s mould — two other brands were selling the same unit within a season, and the margin went with it.

Holding our brand reference took real work: one Pantone, three runs, no drift. Two seasons on, the SKU is still ours — no second tooling spend, unit cost unchanged, repeat rate 98%, defect rate 0.5%.

“The cut-out matched the incumbent. There was no line change.”

A fixed recess cut-out and 12V scheme: the last supplier drifted millimetres between lots and failed end-of-line. We checked drawings against the recess and sampled through our own fixture.

Every lot since has cleared AQL 2.5. A field failure is now a repair in the yard, not a scrapped trailer — 600 units, no dimensional reject.

Before you write

The questions buyers ask about us

Not the product questions — those sit with the line. These are the ones about who you would actually be buying from.

01Are you the manufacturer, or a trading company?
A manufacturer, with a sourcing arm built around it. The heaters are engineered and produced on our own Shunde lines. Housings, accessories and components come from an audited partner network, which is why we can cover a whole program rather than the heater alone. The founder’s account of why it was set up that way is above.
02What size of program do you take on?
A first order does not have to fill a container — a platform SKU on our unit with your branding starts low. What we are looking for is a program with a plan behind it: a market, an annual volume and a sense of whether it is one SKU or a line.
03Who would we be working with day to day?
The people listed in the team section above — operations, sales, engineering — not a call centre. Your product or plumbing engineer talks to ours directly, in English, and the same person stays on the program rather than being rotated between accounts.
04Can we visit the plant, or send someone on our behalf?
Yes to both. We host factory tours and video audits, and third-party inspection — SGS, TÜV or your own agent — is welcome at any stage. A third-party audit of the plant is already on file if you would rather start from that.
05How long before we see a physical sample?
Send a drawing, a reference unit or a brief and the first reply is a sampling plan with a custom list, checking fit against your housing or vehicle before anything is quoted. Physical samples follow once the line plan is approved — usually inside 10–18 days.
06Do you only take established brands?
No. The first order is often a single SKU testing a market, and the tooling and pack decisions stay reversible until you know it sells. What we ask for is an honest volume estimate — scoping a starting point is easier than walking a program back.
