ABSTRACT:
A heating system for a vehicle passenger compartment provides a heat reservoir wherein heat energy from the engine exhaust means may be stored until needed to heat the passenger compartment, for example, when the vehicle is operated with a cold running engine. The reservoir absorbs the heat from the engine exhaust pipe through absorption means which may include sodium as a heat transmission medium and which operate to limit the heat transfer between the exhaust system and the reservoir to levels of exhaust gas temperature above a predetermined minimum. A vacuum chamber surrounding the heat reservoir may have a heat transfer fluid, such as freon, introduced therein to transmit the stored heat to air which is to be supplied to the vehicle passenger compartment.
