  • How do I adjust my boiler pressure properly? – Energuide

    The pressure gauge needle indicates the actual pressure of the system. A green zone shows the correct pressure range, while a red zone shows the critical zone.: A red needle serves as a marker, while a black needle corresponds to the actual pressure.These two needles should be on top of one other.: In some boiler models, the water pressure is given by indicator lights on the control panel.Learn More

  • What to do if your boiler loses pressure - British Gas

    If the pressure gauge on your boiler indicates high pressure (above 2.75 bar), then you may need to bleed a radiator to bring the level down to around 1.5 bar. This can be tricky and, occasionally, dangerous; due to high water temperatures.Learn More
