WATER-HEATERS HOW THE YUHUA WATER HEATER WORKS Combustion air from the environment and fuel from the vehicle tank are mixed and ignited in the combustion chamber. The water heater is connected with the vehicle s engine radiator, coolant from the engine is heated by the heater and circulated in the engine s cooling system, thus, the engine is warmed up while the engine is off, this make 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 (warm blower). to connect the engine coolant inlet coolant outlet YOUR WATER HEATER ADVANTAGES YUHUA Water Heater More consistent heat output Automatic operation Remote control is optional (no more than 800 meters) Energy saving, environmental friendly Domestic water heating possible Smart size, flexible installation: Can be installed in the engine compartment Small-diameter pipelines Need-driven heat output either via panel radiators or radiators with fan Avoid wearing and tearing the engine thanks to pre-heat it in the cold winter. Maintenance free and user friendly Optional Function: YUHUA water heater can support radio remote control function, then you can manage your vehicles by your smartphone and apps, this make it possible to pre-heat your vehicles before they start working even you re still in the bedroom! CLASS UPGRADE FOR EXTRA HEAT: If you want to distribute the heat from your YUHUA heater even more precisely throughout the vehicle, then YUHUA water/air convectors are a perfect addition to the water heating system. These extremely fuel efficient and quiet units are available with heat outputs of 5kW and 9 kw for 12 or 24 V applications. 4/7
