ことになる。(Function) According to the hot water heater with additional heating function of the present invention, hot water from the heating heat exchanger is divided into the bath heat exchanger and the additional heating bypass, and the bath heat exchanger is connected to the heating bypass via the heating bypass. Since the bath heat exchanger is connected to the circulating water tank, a portion of the high-temperature water discharged from the heating heat exchanger is constantly circulated to the bath heat exchanger. Therefore, you can freely reheat the bath by using the bath heat exchanger during heating. Also, when reheating the bath during heating, the high-temperature water supplied from the heating heat exchanger releases a large amount of heat when passing through the bath heat exchanger, and the hot water at the outlet of the bath heat exchanger is heated. However, by detecting the temperature of hot water flowing into the heating heat exchanger with a heating thermistor and controlling the flow rate of the reheating bypass flow control valve in a feedback manner, the water is supplied to the heating heat exchanger. The water temperature is always maintained above the minimum hot water temperature, providing a stable heating sensation.

能力を高めることができる。 In the above configuration, when the bath circulation pump 7 is operated during heating, when the high-temperature hot water supplied from the heating heat exchanger 2 passes through the bath heat exchanger 6, a large amount of heat is transferred to the water circulating from the bathtub 8. The bath is reheated. Therefore, when the bath is reheated, the temperature of the hot water supplied from the heating heat exchanger 2 to the bath heat exchanger 6 becomes lower at the outlet of the bath heat exchanger 6.
A part of the circulating water whose hot water temperature has become low is directly returned to the circulating water tank 4 through the heating bypass 9, and the remaining part is returned to the circulating water tank 4 after passing through the heating heat exchanger 5 and heating the room. . The temperature of the hot water flowing from the bath heat exchanger 6 to the heating heat exchanger 5 is detected by the heating water temperature sensor 1, and when the hot water temperature falls below a predetermined minimum water temperature, the flow rate of the reheating bypass 10 is controlled. The valve 11 is wide open by feedback control, and a large amount of high-temperature water is not passed through the bath heat exchanger 6, but downstream of the bath heat exchanger 6,
In addition, the heating heat exchanger 5 is introduced closer to the heating heat exchanger 5 than the branch point of the heating bypass 9.
The temperature of the circulating water supplied to the room is always maintained above the minimum hot water temperature, providing a stable heating sensation. In addition, by introducing high-temperature water to the heating heat exchanger 5 side from the branch point of the heating bypass 9, the temperature of the circulating water supplied to the heating heat exchanger 5 can be lowered to the lowest temperature with a small amount of high-temperature water. It is possible to maintain the hot water above the bath temperature, and by circulating a large amount of high-temperature water in the bath heat exchanger 6, the reheating ability can be increased.
