Applications range from engine preheating to supplemental heating.
These water systems are compact with all heat creation , fan distribution and plumbing neatly packaged within the unit. The heaters have from two to four heat levels and cycle between these levels to maintain a constant water temperature called for by the control unit. When heat is called for by the switch or timer, a control unit signals the units intergrated water pump to start circulating the coolant. Simultaneously a blower motor draws combustion air into the heaters ignition chamber and fuel is drawn into the chamber by the heater's fuel pump and mixed with the air. Fuel is typically drawn in from the exsisting fuel tank .
