Suggest you repeat the test tonight...
1. Start with a cold boiler.
2. Top-up to 2 bar.
3. Isolate ONLY the heating flowand return pipework.
4. Switch off the boiler.
5. Review in the morning
Pressure remained at 0 so I had to manually top it up.and what happened when you opened the isolaion valves after your test ? did the pressure jump back up ?
Is there any way of identifying where the leak is without ripping up fllorboards and walls? Is there a way to test one set of pipes at a time?As already advised ,your leak is on the system not the boiler.
The leak is on your system, if it wasnt leaking the pressure would have went up a bit when you opened the isolation valvesPressure remained at 0 so I had to manually top it up.
I already checked all visible pipes. There's no wet patches on any ceilings. Radiators are all dry. This leaves ground flooring. I suspect it could be the pipes ubder the dining room floor boards. That rood was converted 3 years ago and builders installed new pipes and radiators.Water leaks on upper floors would inevitably be visibly apparent. Leaks on ground floor ,pipes buried in concrete etc are far more difficult . You should make a thorough inspection around any area known to have pipes buried ,looking for any tell tale signs or damp areas .
There are specialist company's / equipment for leak detection if
all else fails ,as they are not cheap.
The only place with floor tiles is the kitchen. Otherwise rest is floorboard.I am afraid lifting floor boards up would be the next step . What area has concrete flooring with buried pipes in concrete ?
