Hello,
Can anybody please advise.
For months now our old Ideal Mini HE C24 (combi boiler) has had pressure problems. It won't stay above 1 bar. Occasionally I top it up, to above one bar, twice in a day, other times if I am happy to leave it about a 1/3 of a bar it won't complain for a week. Usually I would probably top it up a couple of times a week, on average.
We live in a house with concrete foundations and all the pipework is above ground or on the 1st floor below the floor boards. There is no sign of a leak anywhere. No damp patches on the ceilings, no raised flooring, nothing that would indicate a leak. Of course some of the pipework is boxed in but there are no signs at the bottoms of the boxing. Some piping is behind kitchen cupboards but the floor underneath is dry.
If I top up the pressure to above 1 bar there will sometimes be a slow slow gentle drip from the PRV outside, but never a gush. If the pressure is low then nothing comes out.
The pressure goes up to near 2 bars when the heating is on.
So as I can not see any sign of a leak in the house I have assumed it is the boiler being wrong somewhere. I have had a couple of people in and they don't seem to agree. I am told if there was a problem with the boiler water would be squirting out of the PRV. I just don't see how I can have a leak in the house, for such a long time, with no signs at all.
Might anybody have any ideas or suggestions please?
Is there any way to easily check if it is the boiler or the system? I have read something about isolating the boiler but I am not really sure.
Also in the last few weeks the boiler has become more unhappy and sometimes won't fire for hot water, though it always works for heating.
We do need a new boiler but unless the leak is sourced it seems that is not a good idea.
Thank you.
