Boiler fitted September 2017 along with 2 other same boilers in other properties. One is now giving us grieve. Pressure was in the green -1 bar- 3 radiators were not heating properly so they were bled and then of course the boiler needed topped up. This was done to 1.5 bar. Then when boiler fired up it then went up to 2 bar on the gauge. 5 days later the pressure was below 1 bar so we topped it up again. Engineers came from Worcester and said that the expansion vessel was not at the correct pressure so this was topped up and then they refilled it to 1.5 bar. It has now been a further 2 weeks and they pressure is again moving from 0.5 bar when boiler off and up to 1 bar when boiler is on???? The engineers say we must have a leak in the system pipework however how can this be if for 4 months all was okay until bleeding radiators?? Would this not have happened before now? and if it was a leak how can the pressure go from the red to the green when fired up? this does not make any sense. Can anyone shed some light on all of this as engineers coming out again Monday. Do we not need a new expansion vessel. Should have said that when engineers were out they said the expansion vessel was not set at correct pressure and they had to top it up with air however the other 2 boilers were fitted by same engineer so why would he not have set all 3 to the same correct pressure? It baffles me. Should also say we realise that boilers of this nature do needed topping up a few times a year and we have topped up the other 2 with no issues whatsoever.
