PURPOSE: To make uniform the temperature of hot water within a bathtub and make it possible to supply remaining hot water in the bathtub to a washing machine by the utilization of a forced circulation effect by carrying out circulation of hot water in the bathtub to the heater by the forced circulation due to a circulating pump, providing a three-way valve in a circulation path, and supplying selectively hot water to either of the bathtub and the washing machine.
CONSTITUTION: The bathtub 1 and bath heater 2 are designed so that the hot water within the bathtub is circulated by a circulating passage 3, and a circulating pump P1 and a thermistor T for detecting the temperature of water in the bathtub are provided. The hot water in the bathtub passing through the circulating passage 3 consisting of an upstream circulating passage 31 and a downstream circulating passage 32 is forcibly circulated. In the route of the downstream passage 32, a three-way valve V1 is provided, and hot water in the bathtub is supplied to the washing machine W by a changeover. In heating coil 21 of the bath heater 2, hot water is supplied and circulated by a circulating pipeline 41 from the hot water boiler 4, and hot water forcibly circulated by a circulating pump P2 flows into the heating coil 21.
