PURPOSE: A heating system for a vehicle is provided to heat the indoor space of a vehicle with hot water by arranging heating pipes on every seat of passengers and circulating the hot water through the pipes. CONSTITUTION: High-temperature water is supplied to a heating instrument(3) from a water jacket(2) by starting an engine(1). The heating instrument changes the water into proper temperature and the water is fed to a feed pipe(9a) by a circulating pump(11). Passengers obtain heating effect when the hot water is supplied to each heating pipe(6,7,8) by opening isolation valves(10). The indoor temperature of a vehicle rises by continuing to supply the hot water to a seat(5) not occupied by a passenger.
