What does the boiler pressure mean?
The pressure must not be too high, 1.2 to 1.5 is the most appropriate range, more than will reduce the life of the sealing parts, too little pressure will not start the phenomenon, the solution is to open the bleed valve to open the water, open the water switch add water. Gas-fired boiler (also known as gas-fired heating water heater, see GB-2017 "gas heating water heater") is based on natural gas, artificial gas or liquefied petroleum gas as fuel, fuel burner output, combustion in the combustion chamber, by The heat exchanger absorbs the heat, and the circulating water in the heating system passes through the heat exchanger and is heated by reciprocating heat to continuously output heat to the building to provide heat to the building. In addition to the general dual-use gas boiler with heating function, both hot water function (that is, in addition to heating, but also with gas water heater function). The boiler can provide heat for the heat sink or heat source for the floor heating system. Commonly used wall-hung boilers are divided into two types of heating and heating dual-purpose furnaces and single-floor furnaces.
In the wall of the boiler next to a valve with a screwdriver can open the knob to open it can be pressed to see the pressure gauge to 1.5 or so when the stop, you can
Wall furnace pressure generally refers to the addition of external boiler outside the boiler to increase the amount of heating hot water circulation to improve the head to meet the 2 or 3 layers of heating requirements
