なることがない等の効果を有する。(Effect of the invention) As described above, according to the invention, the temperature sensing element 13 and the temperature sensing element 1 are provided in the introduction path 6 of the hot water faucet 5.
3 and a throttle valve 14 that throttles the flow path, the water discharged during the hot water waiting time when the hot water faucet 5 is opened is not activated by the temperature detection element 13 while the temperature is low. Therefore, the water in the pipe 7 is circulated and heated in a closed circuit including heat exchange while the water is being discharged in a small amount, and when the temperature reaches an appropriate temperature, the throttle valve 14 is opened, so that unnecessary water discharge can be prevented as much as possible. Especially when there are many hot water faucets 5 in the piping 7, the amount of cold water discharged from the inlet channel 6 even if it is downstream.
The amount of water remaining in the tank does not exceed the amount of water remaining in the tank, and unnecessary water discharge can be prevented.When hot water is supplied after the hot water waiting time, the throttle valve 14 is opened by the operation of the temperature detection element 13 according to the temperature of the hot water, and hot water is supplied. This has the effect of not being a hindrance.
