Hi, I have recently moved into a house with the above mentioned combi boiler. My central heating and hot water all seem to run as expected, but I have recently noticed that when my central heating is off that my pressure gauge is at 0!
When I turn the heating on it goes to about 1.25.
Is this correct? I thought the heating was all in a closed loop and that the pressure should stay constant whether the heating is on or off.
Ive tried a google search to see if this is expected, everything I find makes me think its not, but the fact my heating etc all works ok makes me wonder.
Thanks in advance
PS Im a total novice with these things, but I will try and answer all replies as best I can
