PURPOSE:To save energy, by making the temperture of a bath proper and uniform, by stabilizing the level of water to reduce the loss due to overflow, and utilizing solar heat. CONSTITUTION:The bathtub 1, a lower takeout outlet 3, a pipe 4, a boiler 5 and a hot water supply port 4 constitutes a circulating path, and a mixing three-way valve 9 is connected by a pipe 10 that bypasses the boiler 5. The three-way valve 9 is controlled by a temperature sensor 11. The flow rate in the pipe 10 is made larger than the flow rate to the boiler 5. The signal from a level sensor 13 of the bathtub 1 controls the valve 16 of a water supply pipe 15 connected upstream of a pump 6. A heat accumulating reservoir 18 connected to a solar heat collector 17 is connected via a pump 19 and the boiler 5 to a hot water reservoir 20, and a hot water delivering pipe 22 from the hot water reservoir 20 is connected to water supply loads such as a shower. |
