Abstract: A heater apparatus adapted to be used as an auxiliary unit to the main heater system of a vehicle jointly heats the vehicle engine to operating temperature and heats the fuel line while the engine is inactive. The heater apparatus includes improvements for reducing heat dissipation, providing easy accessibility to the burner assembly, and for automatic ignition of the heating element. In addition, the heater operates directly from the vehicle fuel supply thereby eliminating the need for carrying any auxiliary fuel supply for the heater.
