Boiler Pressure: Reduce or Increase Pressure If Its Too High

Your boiler's pressure is usually displayed on the boiler's built-in pressure gauge, and should read around the 1 bar mark when you are not running any hot water and the central heating is not turned on. Therefore, 1 bar is a low-pressure setting. Why is my boiler pressure high? Once the boiler begins to heat water, the heated water expands and causes the pressure gauge to increase.
