Usually our boiler bar rests at 1.5. for some reason the bar registers 3 today is there something to be done to fix this or is it ok. We have a ferroli DOMIcompact F 24 B
Your boiler should only go up to near 3 bar when you have had your heating on as the water in your system expans when heated and should return to 1.5 when water cools back down.1.5 bar is the normal setting,if you have not had your heating on I suggest water is passing through your quick fill pipe .
To reduce your pressure drain some water from the system via a drain cockor radiator
