Less than a year after having this new boiler fitted the pressure rose, water started discharging on to the roof via the overflow pipe and then the system shut down. The engineer came and said the heat exchanger had gone so water from one part of the system was going into the other and causing the relief valve to pump it out on to the roof . Result new heat exchanger fitted.
Now about 12 months or so later the same sequence of events and again the boiler has stopped - if I turn off the mains supply the central heating works but no hot water at all.
I have 3 questions:
1.This seems to be an inherent fault does anyone know if Vokera have done anything to upgrade the part to avoid inconvenience/ expense for users.
2.As the heat exchanger has already been replaced under warranty I assume as the replacement has now gone the warranty period on it will run not from the time the boiler was bought but from the time the replacement part was fitted is this a correct assumption.
3.I read somewhere that the heat exchanger on this boiler was very easy to fit . I've got some limited plumbing experience eg fitted my own bathroom ie toilet, bath, sink and removed and fitted radiators is replacing the exchanger something I could do and if so can anyone post or point me to step by step instructions.
Oh one last question is there a Vokera users group I couldn't find one.
