PURPOSE:To prevent heat dissipating loss as well as water hammer by a method wherein supplying hot-water is introduced into an additional heating circuit at hot-water pouring circuit and the amount of supplying water is controlled. CONSTITUTION:The outlet of a forced water circulating type heat exchanger 17 is divided in the main body of the device at a branch 22 to supply hot-water from the hot-water pouring circuit 23 into a circulation type heat exchanger 18. A valve driving unit 25 is provided in the circuit 23, a supplying water amount control unit 36 is provided at the inlet of the heat exchanger 17 and a water level detector 37 is provided in the heat exchanger 18, while these units are controlled by a control unit 34 and a setter 35. The valve driving unit 25 is opened by the setter 35 and is closed by the signal of the detector 37 after the operation of the supplying water amount control unit 36. The hot-water is supplied into a bathtub 20 from the heat exchanger 17 through the heat exchanger 18, however, the bathtub 20 can be covered by a lid, therefore, the heat dissipating loss may be prevented. When the hot-water arrives at an objective water level, the flow amount thereof is regulated by the supplying water amount control unit 36 through the signal of the water level detector 37, therefore, water hammer will never be caused. |
