Water Heater Introduction

How the YUHUA Water Heater Works
Inside the water heater, combustion air from the environment and fuel from the vehicle tank are mixed and ignited in the combustion chamber. The water preheater is connected with the vehicle's engine radiator. Coolant from the engine is heated by the heat system and circulated in the engine's cooling system. Thus, the engine is warmed up while the engine is off. This makes it very easy to start the engine in a very cold day in winter. Meanwhile, perfect warm air will be fed into the cabin interior once you start the A/C or warm blower.
