し、給湯維持費が高くつくという欠点があつた。(Problem to be Solved by the Invention) Conventionally, as a heat source for heating the hot water in the hot water storage tank, only air or tap water as a heat exchange medium in an outdoor heat exchanger or an indoor heat exchanger has been used as a heat source. The hot water in the bathtub was simply left unused and was not used as a heat source at all. Therefore, the hot water storage tank heating operation for heating the hot water in the hot water storage tank to a predetermined temperature requires a long time, and the hot water supply maintenance cost is high.

As a result, the refrigerant that flows into the hot water storage tank heat exchanger 16 and radiates heat flows through the pressure reducing mechanism 31 and then flows into the bathtub heat exchanger 29, where it absorbs the waste heat of the bathtub 14, and then flows through the piping 26 to the hot water tank heat exchanger 16 again, so the hot water tank heat exchanger 16 and the bathtub heat exchanger 29
The hot water in the bathtub 14 is heated using the exhaust heat from step 4 as a heat source.
