First, in the operation mode in which the hot water 7 in the hot water storage tank 2 and the hot water 9 in the bathtub 8 are heated and reheated in the dual-purpose unit 20, high-temperature gas refrigerant is supplied to the heat exchanger 4 of the dual-purpose unit 20. What is necessary is to perform an operation in which the water in the pipe 10 and the second inner pipe 11 are heated simultaneously. In addition, in the operation mode in which the hot water 7 in the hot water storage tank 2 is heated by the exhaust heat of the hot water 9 in the bathtub 8, the hot water 9 in the bathtub 8 is flowed to the second inner pipe 11 by natural convection or forced circulation by the pump 25, and is brought into close contact with each other. Both pipes 10,
The hot water 7 in the first inner pipe 10 is directly heated through the inner pipe 11. In this example,
Since both pipes 10 and 11 are housed in the outer container 6 in close contact with each other, the exhaust heat of the hot water 9 in the bathtub 8 is used to cool the hot water storage tank 2.
When heating hot water 7, both pipes 10 and 1
The exhaust heat can be directly transmitted to the hot water 9 through the hot water 9, making it possible to effectively utilize the exhaust heat.
