How does the gas wall hanger work, not only in winter, but also throughout the year to provide hot water for life and use
When you press the switch button of the control panel, the wall-mounted furnace enters into working mode: first, the wind engine initiates the vent outside the room (pre-cleaning phase, discharges residual gas from the combustion chamber) while creating a negative pressure in the combustion chamber; then the wind switch sends the instruction to the circulation pump for it to start and the water in the heating system begins to circulate; then the water switch senses the flow, sends the instruction to the gas-rate valve and opens it; the ignition needle in the combustion chamber is activated first, the gas and the air are mixed and the heat is ignited and absorbed by the heat exchange and heating water above the combustion chamber, which is driven by the circulation pump and transmitted to the indoor heat end。
Because of the negative pressure of the combustion chamber as a result of the work of the wind engine, the gas does not accumulate too much and, together with a reasonable start time for the gas valve, the discharge ignition time does not occur. The achievement of relatively static sound openings and the avoidance of accidents is one of the important criteria for the stability of gas wall hangers。
The connection between the gas ratio valve and the wind mass is through wind pressure switches, which work first, and when the combustion chamber forms a certain negative pressure, the wind pressure switch sends a direction to the gas ratio valve. There is also a flue gas induction system that monitors combustion-generated exhausts, and if they are not discharged after five seconds of combustion, the system will shut down the gas ratio valves and cut off their supply, thereby ensuring their safe operation。
Small knowledge:
The gas wall hangers are of a single heating and dual-use type, which, by definition, provide only heating, while the two types provide both heating and heating water. Users who install single-heating wall hangers may replace hot water tanks with extra water if they need to use hot water for later periods。
