Boiler Pressure and Central Heating System Pressure -- Why

If the boiler pressure is only raised to 1½ bar, with the system cold no water enters the expansion vessel as the water pressure is not enough to compress the air within the expansion vessel. However, as the system heats up, the water pressure will increase and water will start to enter the expansion vessel, compressing the air pocket on the

Why is the pressure valve repeatedly tripping on my water

The cold water that enters the tank expands as it is heated causing the discharge of water due to over-pressure in the tank. Your incoming water pressure (the normal house pressure) is too high. Normal incoming supply pressures are usually around 80 PSIG. If that is the case you may need a pressure reducing valve on the incoming house supply line.
