Boiler Pressure Too High, Low, Keeps Rising, Dropping

Combi boiler pressure increases when the heating is on as your boiler uses fuel (gas, oil etc) to heat the water - this increase in pressure is natural. If your boiler is behaving as it should, the pressure will stabilise again once the system is switched off and cooled down.
