How Do Chinese Water Heaters Operate?

Electric Storage and Instant Heaters

• Electric storage heaters work by filling a tank with water and using electric heating elements to warm it up. The temperature is regulated by a built-in thermostat, which keeps the water hot and ready for use.
• Tankless heaters use powerful heating elements or coils that activate when water flows through the unit. Hot water is provided instantly, and the heater switches off once the tap is closed.

Gas Water Heaters

• Ignite a burner either automatically or via manual lighting.
• Water passes through a heat exchanger above the burner.
• Hot water is delivered when a hot tap is turned on.

Solar Water Heaters

• Collectors (usually panels or tubes) absorb sunlight.
• Heat is transferred to water stored in a tank.
• Often combined with electric or gas boosters for cloudy days or when demand is high.

Diesel Water Heaters

• Diesel fuel is ignited internally.
• Heat is transferred to a coil or block through which water passes.
• Used for both water and space heating in vehicles or remote areas.
