Abstract (en)
[origin: EP3220074A1] An object is to provide a heat exchanger that can effectively suppress scale precipitation without decreasing the flowrate of water flowing inside and that can simplify maintenance work, and a heat-pump hot-water generating device including this heat exchanger. To achieve this object, the heat exchanger includes: a first pipe carrying a heating medium; and a second pipe carrying water that exchanges heat with the heating medium. The heating medium flowing through the first pipe and the water flowing through the second pipe form a counterflow, and the first pipe includes an internal heat exchanger for heat exchange between the heating medium flowing upstream of the first pipe and the heating medium flowing in the first pipe.
