Abstract
A heating system for automobiles utilizing the hot water from the engine cooling system as a heat source includes a heating radiator and a heat accumulating water tank, and pipe lines are provided between the engine cooling system, heating radiator and heat accumulating water tank. The flow passages of the cooling water through the pipe lines are switched by electromagnetic valves provided in the pipe lines so that the heating radiator and the heat accumulating water tank are connected in series or in parallel with each other with respect to the engine cooling system, or a circulating passage is formed between the heating radiator and the heat accumulating water tank. The heat accumulating water tank has a mixing preventing device to prevent cold cooling water flowing into the water tank from mixing with hot water contained in the water tank.
