In a vehicle heating system, heat exchange is made between a combustion gas generated by a burner of a heater and water by a heat exchanger of the heater and the hot water heated by the heat exchanger is sent into a cooling water heater unit of the vehicle for heating. The hot water for heating the vehicle can be obtained by change-over control of a change-over valve from the hot water of the heat exchanger or from the hot water of a radiator of an engine. Furthermore, the combustion gas generated by the burner is sent into an intake or exhaust pipe of the engine. |
