PROBLEM TO BE SOLVED: To provide a heat pump hot-water supplier stabilized in the hot-water discharging characteristics. SOLUTION: The heat pump hot-water supplier is equipped with a refrigerant circuit, in which a compressor 11 for compressing refrigerant, a heat exchanger 14 for producing hot-water by heat exchange between the refrigerant supplied from the compressor 11 and water, a reducer 13 for reducing the pressure of the refrigerant from the heating heat exchanger 14, and an evaporator 12 for effecting heat exchange between the refrigerant from the reducer and outdoor air are connected sequentially through a refrigerant pipeline 26. Further, the supplier has a hot-water supplying circuit, in which a hot-water storage tank 20 for reserving hot-water from the heating heat exchanger 12, a circulating pump 23 for sending water from the hot-water storage tank 20 into the heating heat exchanger 12 and the heating heat exchanger 12 are connected sequentially through a hot-water pipeline 26. In such a heat pump hot-water supplier, the heating heat exchanger 12 is provided on the side surface of the hot-water storage tank 20 while the hot-water pipeline 26 for sending hot-water from the heating heat exchanger to the hot-water storage tank is provided near the side wall of the hot-water storage tank 20. |
