Boiler Pressure and Central Heating System Pressure -- Why It

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. The position of the circulating pump in the system can slightly alter the pressure at the gauge too.
