Abstract

PROBLEM TO BE SOLVED: To prevent a user from feeling cold due to cold water immediately after a mixing faucet 5 is opened, and do without wasting the water. SOLUTION: Before warm water at a preset temperature or above passes through a part, where a temperature sensor 31 is provided, after the mixing faucet 5 is opened, the water flows into a heat insulating tank 22 via the second on-off valve 36 which is opened, and the warm water kept warm by the tank 22 flows toward the mixing faucet 5. Consequently, the warm water at a prescribed temperature is allowed to flow out of an exhaust port 14 of the mixing faucet 5 or a shower head 11 even immediately after the mixing faucet 5 is opened.
