The wall hanging furnace is actually the abbreviation of the gas wall hanging furnace. Can be external indoor thermostat, better control the temperature, to achieve the purpose of energy saving. Let us briefly understand the maintenance method of gas wall hanging boiler. 1. The cause of insufficient pressure failure: After the gas wall-mounted boiler has been running for a long time, its heating system will have a certain pressure drop, which is normal. There may be two reasons: a: The internal pipe sealing of the heating system is not strict, causing the system to leak and the internal water shortage; the internal expansion tank is too small.
