Having bled my radiators yesterday morning, I returned home to find my heating not working. Hot water was on but cold radiators. I realised the pressure was too low on the boiler (0.5 bar) so followed previous instructions to raise it. Unfortunately it went too high -up to 2 bars and the manual says 1.5 bars max. I can't locate the pressure release tap - Should I worry or will it be ok? Someone mentioned it may damage the diaphram??

That's great, thank you, I did misunderstand

you misunderstand me bleed WATER out of a rad about two mugs full this will lower the pressure if that isn't enough bleed some more out

Thanks Brian but they're all bled already. Can it do any damage if I leave it at 2 bars?

2 bar is ok but if you want just bleed water out of a rad until it drops to 1.5
