PROBLEM TO BE SOLVED: To provide a cooling heater capable of preferably performing heating individual operation regardless of an ambient temperature.SOLUTION: A cooling heater comprises: a controller, when performing heating individual operation, supplying the coolant which has passed through a heating side heat exchanger 42 in a return passage 40 to a compressor 21 via a bypass passage 60 by closing a return valve 44 and by opening a bypass valve 62; and an out-warehouse blower fan F2, when driving to rotate normally, supplying ambient air to the circumference of the heating side heat exchanger 42, while when driving to rotate reversely, supplying the ambient air of the compressor 21 to the circumference of the heating side heat exchanger 42. In the controller, when performing heating individual operation and if the value of an ambient temperature exceeds a prescribed threshold, the out-warehouse blower fan F2 is driven to rotate normally, while if the value of an ambient temperature is the prescribed threshold or lower, the out-warehouse blower fan F2 is driven to rotate reversely.
