Then, when the hot water pipe 7 and the hot water pump 8 are suspended from the ground side and the hot water pump 8 is operated to hot water in the upper space of the upper casing 1, Hot water is pumped up by the hot water draw pipe 6 and pumped into the upper casing 1 through the packer 4, and heat exchangers such as the ground-side bath, heating, and hot water supply equipment through the hot water pump 8 and the hot water pipe 7. Hot water can be pumped (not shown).
After the heated hot water is radiated on the ground surface, it is introduced into the lower space of the well-side casing 1 by the low-temperature water reducing pipe 5 that has been lowered to the packer 4 in advance and recirculated hot water. Further, the amount of hot spring water from the hot spring layer 2 can be increased or decreased by increasing or decreasing the amount of water fed through the low-temperature water reducing pipe 5.
When higher temperature water is required, a hot water pump 8 may be disposed near the outlet of the high temperature water draw pipe 6 as shown in FIG.
