The pressure on my utica boiler has been creeping up this winter even when the boiler is cold. The other morning I woke up to a cool house. The boiler was cold but the pressure guage read 5lbs. I had to raise the control unit to 6lbs. to get the boiler to run.
Since the control unit and the gauge are seemingly agreeing with each other, I have to assume that there actually is 5lbs of pressure in the system. But why?
