A heater system associated with an engine is described having a burner disposed on an air intake tube of the engine for burning fuel, and a heat exchanger disposed downstream of the burner. The combusted gas produced by burning the fuel in the burner is introduced into the heat exchanger in which a heating medium such as air or engine cooling water is heated by the heat of the combusted gas. If the heating medium is air, then heated air is delivered by a blower into a passenger compartment to warm the same. If the heating medium is engine cooling water, then it is delivered to a heater core to warm the passenger compartment. The burner has a heater for heating the fuel to vaporize the same and an igniter for igniting the vaporized fuel. The heat exchanger is connected to a tubing serving as a passage for the heating medium, and directional control valves are disposed in the tubing for guiding the heating medium to flow through the heat exchanger or bypassing the heat exchanger. |
