PROBLEM TO BE SOLVED: To provide a heating system for a hybrid vehicle capable of reducing fuel consumption and improving a warming-up property of an engine while securing a heating property in a cabin. SOLUTION: The heating system for a hybrid vehicle comprises an engine cooling path 12 for serially connecting the engine 10 and a radiator 13 for the engine and circulating engine cooling liquid and a strong electricity system cooling path 17 for serially connecting a strong electricity system unit 11 provided with an electric motor and a radiator 16 for a strong electricity system and circulating strong electricity system cooling liquid. A heater unit 20 is connected in parallel with the engine 10 and the strong electricity system unit 11. If the engine cooling liquid is at a certain temperature or lower and the strong electricity system cooling liquid is at a certain temperature or higher, the strong electricity system cooling liquid is supplied to the heater unit 20, which can eliminate the engine operation only for securing a heating performance.
