A heating apparatus having a refrigeration cycle includes a compressor, a condenser and an evaporator. The heating apparatus has a first heat exchanger and a second heat exchanger, where the first heat exchanger is selected as a heat source, and the second heat exchanger is selected as either a cooling or heating source. The first heat exchanger and the second heat exchanger are connected in series with each other in a refrigerant circuit. A heating medium is circulated in a heat transfer device which is connected to the first heat exchanger. Bathwater of a bathtub and water of a hot-water storage tank are heated through the heat transfer device indirectly by the first heat exchanger.
