The working process adopting the device is as follows:
when the controller 32 senses a heating demand, the water pump 24 starts to rotate, the fan 17 is started, the wind pressure monitoring device 18 monitors wind pressure, the controller 32 analyzes whether the wind pressure is normal, if so, the controller 32 sends a command to the ignition device 34, the ignition device 34 performs high-pressure discharge, at the moment, the gas valve 22 is opened, gas enters the burner 20, the high-pressure electricity burns the gas, and the flameout protection device 35 monitors whether the flame is normal. The water pump 24 introduces the water of the heating system from the heating return pipe 27 into the main heat exchanger 19, the water of the heating system is heated by the heat generated by the combustion of the fuel gas, and the heated water flows out from the heating outlet pipe 3 through the heating outlet pipe 3, the three-way valve 8 and the three-way valve 11. When the heating water temperature monitored by the heating water temperature sensor 15 approaches or reaches a set temperature, the controller 32 commands the opening of the gas valve 22 to be reduced so that the amount of gas burned is reduced, thereby maintaining the heating water temperature within the set temperature range. If the opening degree of the gas valve 22 has fallen to the minimum and the heating water outlet temperature is still higher than the set temperature, namely, when the heating demand becomes low, the gas valve 22 is closed, the heating electric heating wire 7 starts to be electrified, the fan 17 is closed after the cleaning procedure is completed, the three-way valve 8 acts, so that the heating water flowing out of the main heat exchanger 19 flows into the electric heating tank 6 through the three-way valve 8 and the heating electric heating water inlet pipe 4, and the heating water heated by the heating electric heating wire 7 flows out of the heating water heater through the heating electric heating water outlet pipe 9, the one-way valve 11, the three-way valve 11 and the heating water outlet pipe 3.
When the controller 32 senses that domestic hot water is required, the heating mode is suspended, the domestic hot water mode is started, heat generated by gas combustion heats heating water in the main heat exchanger 19, the heated heating water flows into the plate heat exchanger 23 through the three-way valve 8 and the three-way valve 11, at the moment, domestic water flows into the plate heat exchanger 23 through the water flow sensor 30 and the three-way valve 28, heat exchange is carried out on the heating water and the domestic water in the plate heat exchanger 23, the domestic water flows out of the plate heat exchanger 23 after being heated, flows out of the gas-electric dual-purpose heating water heater through the three-way valve 12 and the domestic water outlet pipe 14, and the heating water after heat exchange with the domestic water returns to the main heat exchanger 19 through the water pump 24. When the temperature of the domestic water detected by the domestic water outlet temperature sensor 33 reaches or exceeds a set temperature, the controller 32 commands the opening of the gas valve 22 to be reduced, so that the amount of the gas to be combusted is reduced, and the domestic water outlet temperature is maintained within the set temperature range. If the opening of the gas valve 22 has been reduced to the minimum and the water outlet temperature of the domestic water is still higher than the set temperature, the gas valve 22 is closed, the three-way valve 28 is actuated, the domestic water flows into the domestic water and electricity heating tank 26 through the domestic water inlet pipe 31, the water flow sensor 30 and the three-way valve 28, the hot water heating wire 25 starts to be electrified, the fan 17 is closed after the cleaning procedure is completed, and the domestic water heated by the hot water heating wire 25 flows out of the gas and electricity dual-purpose heating water heater through the three-way valve 12 and the domestic water outlet pipe 14.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
