動給湯装置。 A hot water supply control valve, a three-way valve, and a check valve are interposed in a bath water supply path that connects a hot water outlet path of a hot water supply circuit and a bath circuit, and an overflow waterway is connected to discharge water from the three-way valve to the outside, A water pressure switch is provided that is turned on and off based on the differential pressure between the internal pressure of the hot water supply path and the internal pressure of the bath circuit, and when the internal pressure of the hot water tap path is higher than the internal pressure of the bath circuit, the three-way valve is turned on and off on the hot water outlet side of the bath hot water supply path. When the internal pressure of the hot water outlet path is lower than the internal pressure of the bath circuit, the three-way valve is switched in the direction of connecting the bath circuit side portion of the bath hot water supply path to the overflow waterway.
