PROBLEM TO BE SOLVED: To provide a hot-water supplier consisting of a refrigerating cycle capable of obtaining hot-water of 70 deg.C or higher with a condensing pressure not higher than an allowable value. SOLUTION: A water supplying pipe (21) and a hot-water outputting pipe (22) are connected to a hot-water supplying heat exchanger (19) of the refrigerating cycle while a pressure type temperature regulating valve (30), detecting the pressure of refrigerant for the refrigerating cycle to control the flow rate of feed water, is provided in the water supplying pipe (21). The flow rate of feed water controlled by the pressure type temperature regulating valve (30), the heat transfer area, size, degree of super-cooling and the like of the hot-water supplying heat exchanger (10) are determined optimally to obtain hot-water, whose discharging temperature is higher than 70 deg.C, with the compressing pressure lower than 2.15 MPa. |
