Depending on the hot water temperature state, the first gas solenoid valve (11) or the second gas solenoid valve (12) is switched to change the combustion output to the first or second, which is based on the outflow hot water temperature detection device (14). Also, the frequent ON / OFF of the second gas solenoid valves (11) and (12) is minimized. Moreover, when the combustion output is small, the temperature of the inflowing hot water is high, so it is possible to raise the temperature of the hot water to approximately the same as when the combustion output is large.

ものである。(G) Effect of the device As described above, the device of the present invention detects the temperature of hot water in the hot water tank with the inflow temperature detection device provided in the hot water tank and the outflow from the heat exchanger with the outflow temperature detection device. When the temperature is detected and the temperature in the hot water tank is higher than the predetermined temperature lower than the predetermined rising temperature, only the second gas supply path is opened to heat the hot water with a small combustion output, and the temperature in the hot water tank is also increased. Is lower than the predetermined rising temperature and lower than the predetermined temperature, only the first gas supply passage is opened to heat the hot water with a large combustion output. Therefore, when the temperature of the hot water flowing into the heat exchanger, that is, the temperature of the hot water stored in the hot water tank is high, the output can be low, and when the temperature of the hot water is low, the output can be high. Based on this, the ON / OFF frequency of the gas solenoid valve can be reduced as much as possible, the durability of the gas solenoid valve can be significantly improved, and the hot water supply temperature from the heat exchanger is independent of the hot water temperature stored in the hot water tank. It can be kept almost constant, and furthermore, it becomes possible to control the combustion of the gas in accordance with the temperature of the hot water stored in the hot water tank, so the consumption of combustion gas is small, that is, fuel consumption is low. There are practical advantages such as being possible.
