Boiler Pressure and Central Heating System Pressure -- Why It

If the boiler pressure is only raised to 1½ bar, with the system cold no water the water pressure is not enough to compress the air within the expansion vessel. However, as the system heats up, the water pressure will increase and water will start to enter the expansion vessel, compressing the air pocket on the other side of the diaphragm.

Is My Boiler Pressure Too High? | Hometree

Boiler pressure refers to the pressure of hot water running in your sealed central heating system, while water pressure is the pressure of the water coming through your taps. Boiler pressure is important for several reasons. Primarily, if you have low boiler pressure your system could cut out, preventing your central heating from working. Alternatively, if there is high boiler pressure, the system will be strained beyond normal capacity and could potentially fail.

My Boiler Pressure is Too High? A 24|7 Home Rescue Guide

We often say that a boilers pressure should be at around one bar, but this is only when your central heating is turned off and you are not running any hot water. When your boiler starts heating up water, the water expands (think of how steam takes up more space than water), which causes the pressure gauge to jump up.
