When it comes to wall-mounted gas boilers, I’m sure my friends all know that they play a crucial role in winter by providing hot water through natural gas. However, when using a gas-fired wall-mounted boiler, it’s important to choose the right model; otherwise, the heating performance in the future may be poor. So how does a gas-fired wall-mounted boiler work? Let’s take a closer look. The operating principle of a gas-fired wall-mounted boiler is as follows: When the ignition switch is turned on, the fan starts up, creating a negative pressure differential inside the combustion chamber. This triggers the air-pressure switch to send a signal to the circulating pump, which then starts. In turn, the flow switch sends a signal to the high-pressure safety device and to the gas proportional valve, causing the latter to open. Thanks to the negative pressure in the combustion chamber, natural gas is drawn in steadily without pooling or igniting prematurely, thus preventing knocking and ensuring quiet, ultra-silent ignition—minimizing the risk of accidents and maintaining stable operation. The system also includes interlock controls among the gas proportional valve, air-pressure switch, and flue-gas draft switch: only when the combustion chamber maintains a certain level of negative pressure can the gas proportional valve function; if the flue-gas draft switch fails to detect proper exhaust flow within five seconds, it will immediately shut off the gas proportional valve and stop the gas supply.
