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

2020-6-9 · 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.
