ABSTRACT:
A vehicle heating system for use with an engine having a liquid cooling circuit in which a heat storage battery stores latent heat during the operation of the engine, and the latent heat is later used to supply heat to the engine and the passenger compartment heating system during a subsequent use of the vehicle. A bypass circuit is provided within the heating system for bypassing the heat storage battery, whereby recharging of the heat storage battery is prevented until after the engine of the vehicle has reached a desired operating temperature.
