PROBLEM TO BE SOLVED: To provide a heating device for a vehicle capable of improving heating performance upon warming-up of an internal combustion engine.SOLUTION: As a heating device for a vehicle, two systems of cooling circuits of a first cooling circuit in which a first cooling medium for cooling an internal combustion engine is circulated and a second cooling circuit in which an intercooler of a supercharger is arranged and a second cooling medium for cooling supercharged intake air is circulated are arranged. Further, a heater core which is arranged on the first cooling circuit and the second cooling circuit and heats air-conditioning air to the vehicle in which the internal combustion engine is mounted by using at least one of the first cooling medium and the second cooling medium as a heat source is arranged. In the heating device for the vehicle configured thus, when temperature of the second cooling medium is higher than temperature of the first cooling medium, the air-conditioning air is heated by using the second cooling medium as the heat source. |
