ーモの接点が閉じてポンプが駆動する。Operation When the hot water faucet is opened, the contacts of the heater thermometer are closed and the contacts of the hot water tap thermometer are also closed, so the gas solenoid valve opens and the heat exchanger is heated and the pump is driven. When the hot water faucet is closed, the pump continues to be driven until the heater thermometer contact opens. During that time, the hot water output thermometer contact opens and the gas solenoid valve closes, and the pump is driven to connect the heat exchanger and the circulation path. A cycle takes place. Also, when the outside air becomes cold, the antifreeze thermostat's contacts close and the pump is activated.

ンプ６も停止する。 The present invention has such a configuration, and when the water is stopped when hot water is not used, the heater thermometer 2 reaches the set temperature (for example, 40℃) and opens the electric circuit.
The hot water tap thermometer 5 closes an electric circuit when the temperature is below a set temperature (for example, 90° C.). The antifreeze thermostat 14 opens the electric circuit when the temperature is higher than a set temperature (for example, 4° C.). Therefore, the gas solenoid valve 12 is closed and the pump 6 is in a stopped state. Now, when the hot water faucet 10 is opened, the heater thermo 2 is cooled by the water flowing through it, and its contacts are closed, the gas electromagnetic valve 12 is opened, and the gas burner 13 starts combustion. At this time, the pump 6 is also activated. Therefore, a large amount of hot water can be supplied even at extremely low water pressure. Next, when the hot water faucet 10 is closed, the heater thermo2 and hot water tap thermo5
Both close the circuit, so the pump 6 continues to operate and the gas burner 13 also continues to burn.
After a while, the temperature of the hot water in the circulation system increases, and the hot water tap thermometer 5 reaches the set temperature and is turned off, closing the gas solenoid valve 12 and extinguishing the gas burner 13. Since the pump continues to operate, heat exchanger 4
This reduces the after-boiling phenomenon inside the tank. Thereafter, the heater thermometer 2 also reaches the set temperature, opens the circuit, and the pump 6 also stops.
