PROBLEM TO BE SOLVED: To improve heat insulation properties between a hot water storage tank and an outdoor heat exchanger which is accommodated in an accommodation portion provided in a molded insulation material heat-insulating the hot water storage tank.SOLUTION: An outdoor heat exchanger 11 is accommodated in an accommodation portion 25 formed like a concave shape in a molded insulation material 23a. In a back face side and a top face side of the outdoor heat exchanger 11 in the accommodation portion 25, there are provided a back face contact portion 29 and a top face contact portion 30 which restrict an accommodation position to a more downward and more forward side of the accommodation portion 25. The back face contact portion 29 comes into contact with a back face of the outdoor heat exchanger 11 and the top face contact portion 30 comes into contact with a top face of the outdoor heat exchanger 11, thereby forming a hollow heat-insulation space 28 in sides of the back and top faces of the outdoor heat exchanger 11. |
