  • Boiler Pressure and Central Heating System Pressure - …

    With very rare exceptions, central heating systems with combi or system boilers don't use a header tank. 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 boiler pressure will usually rise a little, normally by up to half a bar.
