Feb 14, 2022 · The central heating system is sealed (closed) and pressurised, usually to between 1 and 1.5 bar (cold). This pressure is the boiler pressure. When the system heats up, the water expands, taking up more space. The boiler pressure will rise a little, normally by up to half a bar.Get Price
When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.Get Price
