How do I adjust my boiler pressure properly? - Energuide

Your boiler must be at the correct pressure for the hot water to circulate properly between the radiators, especially if they are on different floors.Generally, the ideal pressure is between 1 and 2 bars, but this may vary from boiler to boiler.Ask your heating engineer. Check the pressure gauge. A quick look at the pressure gauge is enough to check your boiler's pressure.

Boiler Pressure Too High: How to Reduce it | Living by

Once the boiler begins to heat water, the heated water expands and causes the pressure gauge to increase. With an expansion vessel, boilers are well-set to control these quick leaps in pressure so you don't need to worry if the boiler shows a higher pressure than you expected when you are both using the central heating and running hot water.
