EXPANSION VESSEL PRESSURE
When the system water is heated, the pressure will rise above the Cold Fill setting. If the pressure reaches
2.5 bar when the Boiler is operated at its highest temperature with all radiators in circulation, then an
additional expansion vessel must be fitted in the system. Refer to Section 4:6 and BS: 7074 Part 1 for
information on sizing of the additional expansion vessel.
