The three-way valve 51 is switched to a state in which the water direct pipe 49 and the downstream water supply pipe 53 communicate with each other and the water direct pipe 49 and the water communication pipe 57 are closed.
In the state where the three-way valves 47 and 51 are switched as described above, a water direct route is formed by the upstream water supply pipe 45, the three-way valve 47, the water direct passage pipe 49, the three-way valve 51, and the downstream water supply pipe 53.

Then, the hot water amount adjusting knob 17 and the water amount adjusting knob 19 of the mixing faucet 15 are turned to mix hot hot water and water and discharge hot water having an appropriate temperature from the water discharge pipe 23 and supply it to the bathtub 25.
When hot water is supplied to the bathtub 25 as described above, hot water from the hot water heater 31 passes through the upstream hot water pipe 33, the three-way valve 35, the cooling / heating pipe 3, the three-way valve 37, and the downstream hot water pipe 39 as shown in FIG. To the mixing tap 15. Further, water is sent from the water supply 43 to the mixing faucet 15 through the upstream water supply pipe 45, the three-way valve 47, the water direct passage pipe 49, the three-way valve 51 and the downstream water supply pipe 53.
Since hot water passes through the meandering portion 5 of the cooling / heating pipe 3 as described above, heat is radiated from the meandering portion 5 and the floor surface F is warmed.

Next, the operation | movement which cools the floor F is demonstrated.
First, in order to cool the floor surface F, the three-way valves 35 and 37 as hot water supply route switching means and the three-way valves 47 and 51 as water supply route switching means are switched to the next state.
The three-way valve 35 is switched to a state in which the upstream hot water supply pipe 33 and the hot water direct pipe 41 communicate with each other and the upstream hot water supply pipe 33 and the cooling / heating pipe 3 are closed.
The three-way valve 37 is switched to a state in which the hot water direct pipe 41 and the downstream hot water supply pipe 39 communicate with each other and the cooling / heating pipe 3 and the downstream hot water supply pipe 39 are closed.
In the state where the three-way valves 35 and 37 are switched as described above, a hot water direct route is formed by the upstream hot water supply pipe 33, the three-way valve 35, the hot water direct passage pipe 41, the three-way valve 37 and the downstream hot water supply pipe 39.
The three-way valve 47 is switched to a state in which the upstream water supply pipe 45 and the water communication pipe 55 communicate with each other and the upstream water supply pipe 45 and the water direct communication pipe 49 are closed.
The three-way valve 51 is switched to a state in which the water communication pipe 57 and the downstream water supply pipe 53 communicate with each other and the water direct pipe 49 and the downstream water supply pipe 53 are closed.
In the state where the three-way valves 47 and 51 are switched as described above, the water passage route is provided by the upstream water supply pipe 45, the three-way valve 47, the water communication pipe 55, the cooling / heating pipe 3, the water communication pipe 57, the three-way valve 51, and the downstream water supply pipe 53. Is formed.
Thus, the hot water passage route and the water passage route can be opened alternatively.

Then, the hot water amount adjusting knob 17 and the water amount adjusting knob 19 of the mixing faucet 15 are turned to mix hot hot water and water and discharge hot water having an appropriate temperature from the water discharge pipe 23 and supply it to the bathtub 25.
When hot water is supplied to the bathtub 25 as described above, hot water from the hot water heater 31 is supplied with the upstream hot water pipe 33, the three-way valve 35, the hot water direct pipe 41, the three-way valve 37, and the downstream hot water pipe 39 as shown in FIG. Then, it is sent to the mixing faucet 15. In addition, water from the water supply 43 is sent to the mixed water faucet 15 through the upstream water supply pipe 45, the three-way valve 47, the water communication pipe 55, the cooling / heating pipe 3, the water communication pipe 57, the three-way valve 51, and the downstream water supply pipe 53. .
Since the water passes through the meandering portion 5 of the cooling / heating pipe 3 as described above, the floor surface F is cooled.

Therefore, the floor surface F can be warmed only by storing hot water in the bathtub 25, or the floor surface F can be cooled simply by storing hot water in the bathtub 25 after switching the three-way valves 35, 37, 47, 51. . That is, after switching between the hot water supply route and the water supply route, floor heating can be performed in winter and floor cooling can be performed in summer simply by using domestic water in the hot water use section / water use section.
When the floor cooling / heating device is not used, the three-way valves 35, 37, 47, 51 are switched to the above-described hot water direct route and water direct route, and the floor cooling / heating device is stopped.
