摘要： PROBLEM TO BE SOLVED: To reheat bathtub water of bath, without having to deprive the heat of a supply hot water. SOLUTION: When heating only a supply hot water, a heat pump circuit 10 is switched at a refrigerant circulating passage so as to sequentially circulate a refrigerant through a compressor 11, a supply hot water side heat exchanger 12, a second pressure reducing unit 13, and an atmospheric side heat exchanger 15. When heating the supply hot water while pumping a heat from the hot water of the bath, the passage is switched to sequentially circulate the refrigerant through the compressor 11, the exchanger 12, a first pressure reducing unit 14 and a bath side heat exchanger 16. When reheating the bathtub water while heating the supply hot eater, the passage is switched to sequentially circulate the refrigerant through the compressor 11, the exchanger 12, the exchanger 16 and the unit 14. Thus, the bathtub water can be reheated without depriving the heat of the supply hot water.
