It is not unusual for your combi boiler's pressure to increase when the heating is on or the hot water is running, but the pressure should generally not increase by more than 0.5 - 1 bar when there is demand on the system. The reason that the pressure gauge jump ups is that the water inside your boiler expands as it heats up. Your boiler is designed to handle these rapid jumps in pressure
