Boiler Pressure and Central Heating System Pressure -- Wh

Boiler pressure stays too high. If your boiler pressure stays too high despite water being drained out of the system via a drain cock, there is a fault. In this case you should check where the safety pipe from the 3 bar pressure relief valve dumps its water. This is usually directly outside through a wall or into an internal tun dish.

FAQ the Water Boiler Is Overheating and/or Has Hig

It could be allowing house pressure to enter the boiler and cause the relief valve to blow off pressure. Similarly, a pinhole leak in the domestic water coil will also allow house pressure to enter the boiler. In both cases, the water pressure will steadily increase regardless of the water temperature.
