Customizable Services

1. Back Shell – The Sturdy Foundation of the Unit

The back shell serves as the “skeleton” of the water heater, bearing the entire unit’s weight and protecting its internal core components. We use galvanized thickened steel plates, not ordinary painted sheets. These are processed with high‑temperature spray coating, effectively preventing rust, peeling, and color fading, while also offering acid, alkali, and corrosion resistance – greatly enhancing product durability.

Notably, the back shell features an anti‑UV spray finish (e.g., silver metallic paint applied through a two‑coat, two‑bake process). This finish is scratch‑resistant, anti‑corrosive, and resistant to UV aging, ensuring the shell does not yellow or discolor even under prolonged sunlight exposure – it stays looking new for years. All steel and galvanized materials comply with national or industry standards, providing sufficient mechanical strength and rigidity to withstand normal operating temperatures and pressures.

2. Heat Exchanger – The Core of Thermal Conversion
The heat exchanger directly determines the energy efficiency of the unit. We adopt a specially thickened heat exchanger assembly (approximately 0.2 mm thicker than standard models), which not only extends service life but also effectively improves thermal conductivity. The efficient heat‑exchange design reduces surface temperature rise, enhancing user comfort. Made of high‑quality copper, it offers fast heat transfer, excellent corrosion resistance, and higher thermal efficiency. Depending on your specific requirements, we can equip your selected models with heat exchangers made of oxygen-free copper, tin-plated copper, or stainless steel.

3. Induction Needle – The “Guardian” of Safe Combustion
The induction needle is the critical component of the flame‑failure protection system. It constantly senses whether the flame is burning normally. In the event of an accidental flame outage, the induction needle automatically cuts off the gas supply to prevent gas leakage. The principle: the flame generates an induction current, and the controller maintains the gas valve open upon receiving this signal; once the flame is lost, the signal stops, and the valve closes instantly. This safeguard gives you complete peace of mind.

4. Burner – The Source of Powerful Heat
The burner is the “heart” of the water heater. We use an advanced T‑shaped flame burner that optimises the combustion structure and enlarges the combustion area, promoting full mixing of gas and air for more complete combustion and higher thermal efficiency. Combined with a secondary oxygen‑supply combustion chamber, combustion is cleaner and more thorough, effectively reducing nitrogen oxide (NOx) emissions – both environmentally friendly and energy‑saving. The flame is stable, with minimal flame lift, no yellow tipping, and low combustion noise.

5. Gas/Water Valve Assembly – The Precision “Control Centre”
The gas/water valve assembly acts as the unit’s “neural switch”, sensing water pressure and controlling gas on/off. A water‑control device detects water flow pressure and automatically opens/closes the gas valve. A built‑in pressure‑stabilising function ensures a stable gas supply, preventing risks like yellow flames, flame lift, flameout, or deflagration caused by unstable gas pressure. The precision design allows linear gas flow modulation, offering more accurate water temperature control and a superior user experience.

6. Water Inlet Pipe – The First Step for Stable Water Supply
The inlet pipe brings cold water into the system. Made of high‑quality copper, it resists corrosion and aging. Some designs use the incoming cold water to exchange heat with the high‑temperature connecting pipe, effectively reducing the temperature rise during standby (stop‑temperature rise). Selected models include a built‑in water filter to prevent impurities from entering and damaging internal components.

7. Battery Box – Reliable Power Supply
The battery box provides the power source for the pulse ignition system. Designed with anti‑short‑circuit protection (tested with a 0.5‑mm steel pin to ensure no bridging between opposite‑polarity components), it features sufficient partition height and safe construction. It accommodates standard D‑size batteries, holding them firmly with reliable contacts, ensuring the ignition system is always ready to operate.

8. Cover (Exhaust Hood / Flue Collector) – The Efficient Flue Gas Guide
The cover (exhaust hood) sits above the combustion chamber, collecting and directing combustion flue gases smoothly into the exhaust pipe. It is manufactured from thickened cold‑rolled steel with a high‑temperature‑resistant anti‑corrosion coating that resists deformation and rust even under prolonged heat exposure. The internal streamlined flow‑guide design reduces exhaust resistance and prevents flue gas backflow. An integrated anti‑draft damper effectively blocks strong outdoor winds from blowing into the unit, preventing flameout or unstable combustion. Working in close coordination with the heat exchanger, the hood also recovers partial waste heat, further boosting overall thermal efficiency. 

9. Fireproof Plate – The Ultimate Safety Barrier
The fireproof plate is a critical line of defence in the safety design. Installed inside the unit, it effectively blocks heat from transferring to the outer casing, keeping surface temperatures within safe limits. When the water heater is mounted on a combustible wall, the fireproof plate is especially vital for fire safety. This design ensures you can use the appliance with complete confidence.

10. Water Outlet Pipe – The Channel for Consistent Hot Water
The outlet pipe delivers heated water to your tap points. Crafted from premium copper, it withstands high temperatures and corrosion. Working in tandem with an intelligent temperature‑control system, it can monitor water flow changes in real time and precisely adjust output, ensuring stable water temperature even when multiple points are used simultaneously throughout the house.

11. Pulse Ignition Device – The Instant Start‑up Activator
The pulse ignition device consists of electronic components that form a high‑frequency oscillator, generating high‑voltage sparks to ignite the gas at the burner. We use a fully silent pulse igniter with a lifespan far exceeding 100,000 cycles – well above international standards. It offers reliable ignition, stable performance, and long service life, so you never have to worry about misfires.

12. Knob – High temperature resistance and corrosion resistance

Various styles of knobs customized for you. Weather-Resistant Material – Looks and Performs Like New —— Made of flame-retardant ABS engineering plastic, compliant with national electrical safety standards. Enhanced with anti-UV and heat-resistant formulations to prevent brittleness, deformation, or discoloration over long-term use. Even when installed in kitchens or balconies with significant temperature and humidity fluctuations, it maintains stable mechanical performance

For components such as fans, pressure switches, gas proportion valves, and display screens, we will perform performance and safety tests for each gas water heater for customers according to strict testing standards.

② Gas Water Heater Comprehensive Performance Test Bench

Installed at the end of every production line, this test bench performs 100% full inspection on every single finished unit before shipment. It automatically conducts airtightness testing (ensuring zero gas or water leakage) and verifies all safety protection functions – including dry‑burn prevention, flame‑failure shutdown, and tip‑over protection – to confirm they respond correctly. Any unit failing any criterion is instantly rejected and never reaches the market. This final quality gate guarantees that every water heater you receive is fully functional and defect‑free.

③ Gas Water Heater Comprehensive Performance Sub-Test Bench
After the main test bench completes 100% full inspection, this sub-test bench performs a secondary auxiliary check on production units, focusing specifically on water pressure stability – simulating household water pressure fluctuations to verify consistent temperature performance and component sealing under varying pressures. This " re-verification gate " effectively filters out potential issues caused by sudden pressure changes, ensuring every shipped unit has a stable and reliable water circuit. Double inspection, double peace of mind.

④ Electrical Safety Comprehensive Test Bench

After passing performance and sealing inspections, every water heater must undergo 100% electrical safety testing on this bench. The system automatically checks grounding continuity to ensure a reliable connection between the metal casing and the earth wire, eliminating shock hazards; it also conducts high-voltage dielectric strength testing (hipot test) to verify that insulation between live parts and the casing meets standards. Any failure triggers an immediate alarm and lockout, preventing defective units from leaving the factory. This final “ electrical safety insurance ” gives your end users peace of mind and you total confidence in every shipment.

⑤ Precision Salt Spray Test Chamber
During the new sample development phase, we place complete water heaters into our precision salt spray chamber to simulate extreme marine environments with high salinity, high temperature, and high humidity through continuous atomized spray testing. Every metal component – including the back shell, burner, heat exchanger, and pipe fittings – must withstand over 72 hours of exposure without red rust, corrosion, or coating peeling. This “ accelerated aging test ” guarantees that your custom samples remain corrosion-resistant and perform like new, whether destined for coastal cities or island nations.

⑥ Programmable Temperature & Humidity Test Chamber
During the new sample validation phase, we place complete units into our programmable temperature and humidity chamber to simulate extreme climate combinations – including high‑temperature/high‑humidity, low‑temperature/low‑humidity, and rapid thermal cycling – to comprehensively evaluate ignition stability, combustion efficiency, electrical insulation performance, and sealing material weather resistance. Through multiple programmable temperature‑humidity cycling tests, we ensure that your custom samples maintain stable performance no matter whether destined for tropical rainforests, frigid regions, or desert areas with extreme day‑night temperature swings.
⑦ Finished Gas Water Heater Comprehensive Performance Testing Equipment

During new sample validation and batch random inspection of mass production, we use our finished product comprehensive performance testing equipment to conduct energy efficiency coefficient testing (thermal efficiency, flue gas temperature, etc.) and a full scan of all safety indicators – comparing every parameter against national standards (GB 6932) and destination-specific certification requirements (such as CE, CSA, AGA, etc.). The system automatically determines whether each unit meets every criterion, ensuring your products not only deliver excellent performance but also clear customs smoothly and enter the market in full compliance, eliminating risks of returns or penalties due to non-compliance.

⑧ Gas Water Heater Service Life Test Bench
