Mend Ravenheat RSF100ET Overflow Boiler

Ravenheat RSF100ET with low pressure?

I have ravenheat RSF100ET which serves 11 rads over 3 floors with no problems. However during a heating cycle teh pressure on the gauge will increase from the 1 Bar red mark to around 2.5 bar. After it goes cold, you notice it drops below 1 Bar. It keeps getting rid of water through the over flow although the pressure doesn't go above 2.5 bar. Any ideas please?
