6t Atmospheric Pressure Steam Boiler

Boiler Pressure and Central Heating System Pressure -- Why

Where an external expansion vessel is fitted, and the cold boiler pressure is 1 bar, you may see a rapid rise in boiler pressure as the system heats up. This is because, with a pre-charge pressure of 1½ bar, the expansion pocket in the external vessel is only available once the boiler pressure reaches 1½ bar.
