Just had my Heatslave 20/25 oil boiler serviced.
Everything is OK except the system pressure, starting off from cold at just below 1 Bar but when system (heating) is up to temp the pressure has risen to just below 3 Bar.
Checked the expansion tank and that seems fine with a pressure of 1 Bar and no water from the schrader valve.
One thing though is that the expansion tank pressure stays at 1 Bar even when the system pressure is up to 3 Bar.
I am wondering whether the pipe from the boiler to the expansion tank could be blocked.
Any suggestions guys (or gals).
