Since the weather got a little colder our cb28 keeps losing pressure, at least 2 times a day we have to top the pressure up in order to get hot water.
Then when the heating is on, the pressure rising too high, up to 3 bar so water is coming out of the overflow.
Any ideas what might be wrong? I've checked round for leaks and there isn't any that I can visible see on the system.
