To prevent excessively hot water from cascading when temperature of supplied hot water is set too high by mistake in an apparatus for cascading hot water which has a hot water cascading nozzle 41 for cascading, into a bath tab, hot water heated by a heat exchanger 51 for supplying hot water of a heat source machine 5.
The apparatus for cascading hot water includes: an electromagnetic valve 46 of cascading hot water which is arranged in the middle of a hot water cascading channel 42 for supplying hot water to the hot water cascading nozzle 41; a drain pipe 47 branched from the cascading hot water channel 42 in a part upstream from the electromagnetic valve 46 of cascading hot water; an electromagnetic valve 48 of drainage arranged in the middle of the drain pipe 47; and a temperature sensor 45 for detecting temperature of hot water in the cascading hot water channel 42 in a part upstream from a branch of the drain pipe 47. When the temperature detected by the temperature sensor 45 reaches an upper limit temperature or higher, a processing for stopping cascading hot water is performed so that the electromagnetic valve 46 of cascading hot water is closed and that the electromagnetic valve 48 of drainage is opened. When the temperature detected by the temperature sensor 45 is lower than the upper limit temperature, the electromagnetic valve 48 of drainage is closed.
