Hi
I am having problems with my nine year old Vokera Excell SP80 Combi Boiler.
I can only get hot water when the heating is also running. As soon as you turn off the heating you get cold water ?.
The local engineer has been out four times now and has changed the P.C.B, the gas valve (complete) and also a thermistor. None of these parts have made any difference and he has now advised that the system may need de-sludging?.
The system has had fernox in from new so i suspect my engineer is working from pure guesswork.
Any ideas what could be causing this problem?.
Thanks
