2 is a heat collector, 2 is a water heat storage tank, 3 is a circulation pump, 4 is a water supply pipe, 5 is a hot water outlet pipe, and 6 is an auxiliary heat source device. In such a configuration, the heat collection area of the heat collector 1, the capacity of the water heat storage tank 2, etc. are as follows:
So that the price is low and the amount of heat collected is large throughout the year,
It was decided based on the hot water supply load during the interim period. Therefore, in the summer when the amount of solar radiation is high, the heat storage capacity of the water heat storage tank 2 is exceeded while there is still sunlight, making it impossible to collect heat, and in the winter when the amount of solar radiation is low, the water from the water supply pipe 4 Due to the low temperature of the water supply, combined with the small amount of heat collected, there was a drawback that a satisfactory increase in water temperature could not be obtained. Furthermore, even in a short period of time, it is not necessary to directly use the water supply on days when heat cannot be collected, such as on cloudy or rainy days, and the auxiliary heat source unit 6 is designed to tolerate the maximum load that corresponds to the temperature of the water supply in winter. It also had the disadvantage of having a large capacity because it needed to be selected.

's heat storage capacity is full. Then, the three-way valve 8 is switched, and the hot water collected by the heat collector 1 is allowed to flow through the heat storage heat exchanger 9, thereby storing heat in the soil heat storage tank 7. Therefore, when the temperature of the hot water discharged from the water heat storage tank 2 is low, such as in the winter when the amount of heat collected is small, or on cloudy or rainy days, the three-way valve 8' is switched, and the hot water discharged from the water heat storage tank 2 is passed through the heat exchanger 10 for heat radiation. After heating with the amount of heat stored in the soil heat storage tank 7, the auxiliary heat source device 6
Heat the water to the specified temperature and tap the hot water. In this case, since the heat transfer coefficient of soil is small, in the soil heat storage tank 7, the heat exchanger 9 for heat storage is provided at the bottom, the heat exchanger 10 for heat radiation is provided at the top, and the distance between the two is appropriately selected. In particular, the heat stored in the soil heat storage tank 7 can be extracted with a delay of several days, weeks, or months if necessary.
