COMBINATION FAUCET WITH REDUCTION FUNCTION, AND HOT-WATER SUPPLY METHOD THEREFOR

PROBLEM TO BE SOLVED: To prevent water from being wastefully poured off, by discharging only warm water, brought into an suitable-temperature state, from a spout etc., while preventing the discharge of lukewarm water at the initial stage of water discharge from the spout or shower equipment until a water temperature reaches a temperature set by a user, by providing a reduction structure in a combination faucet. SOLUTION: This combination faucet 1 includes: a hot-water supply pipeline 3 and a cold-water supply pipeline 4; a tank 14 for reduction, in which accumulated water accumulated in the hot-water supply pipeline 3 from a hot-water storage tank 5 to a faucet body 2 is returned from a return pipeline 6 connected to the faucet body 2 and temporarily stored; a reduction pipeline 7 which is connected to the faucet body 2, and which supplies the faucet body 2 with the accumulated water stored in the tank 14; and an accumulated water adjusting valve 18 which is provided in the faucet body 2, and which adjusts the opening/closing of the return pipeline 6 and the reduction pipeline 7. When the hot-water supply is performed by the combination faucet 1, the accumulated water accumulated in the hot-water supply pipeline 3 is not discharged; and only the warm water in the hot-water storage tank 5, which reaches the temperature set by the user, is discharged.
