Apologies for length of this post but thought I'm better putting in as much detail as I can...
I have a Ferroli DOMIcompact F 23 B combi boiler (I know they are meant to be rubbish, I've been told this many times) also I have cover with British Gas and have had them out twice but the problem I have seems to persist.
The boiler loses pressure, for example today the pressure was at zero when I woke up so I put 1.2 bar of pressure in at 6am before work and didn't put the heating on, just used hot water for a bath and as I left for work my front door step was wet where it had leaked outside. (I now know it drips from the flue and not the overflow as would be expected)
When I returned from work at 5:30pm despite the heating not been on all day the pressure was at zero.
The British Gas engineers have told me that they believe there is a leak on the system which must be downstairs as if it was upstairs the ceiling would have come through by now. The trouble is, I have laminate flooring in my living room and tiled flooring in my kitchen - both are very difficult to take up and locate a leak though we put the kitchen flooring down 2 years ago and there were no leaks then and pipes are copper so can't see one suddenly developing.
The last time an engineer came he changed the pressure valve and also pumped up a balloon type thing that regulates the pressure or something? and he told me if it still loses pressure it must be a leak.
The only thing is why is it leaking from the flue and not the overflow? As to me this seems to be what is causing the problem.
I would really appreciate if anyone could give me any advise or help - would a leak sealer possibly solve the problem or does water leaking from the flue mean something else or does this just happen to be condensation as it is so cold outside?
Again thank you for reading this what probably looks like war and peace!
