It is an object to sufficiently exercise the energy saving capacity by actively recovering waste heat. A heat pump apparatus 100 includes a heat source unit 301 that cools or heats a refrigerant, an indoor unit 302a that performs a cooling operation, and a hot water supply unit 303 that performs a hot water supply operation. When there is an operation request for one of the indoor unit 302a and the hot water supply unit 303, even when there is no operation request for the other, the heat pump apparatus 100 causes both the one and the other to operate if the other satisfies a certain condition so that the hot water supply unit 303 performs a hot water supply operation by utilizing a refrigerant heated by performing a cooling operation in the indoor unit 302a and the indoor unit 302a performs a cooling operation by utilizing a refrigerant cooled by performing a hot water supply operation in the hot water supply unit 303.
