I am having to re-pressurise the boiler every few days, although it does still work even though the pressure has dropped to near 0 bar.
Can anyone advise how I can find out if the cause is a leak in the radiators / pipework, or a problem with the boiler itself?
I have tried using Fernox to seal the leak, but it only works temporarily.
