TBH even though i fit baxi/potterton combis i wont touch the heat only solo/promax/gold etc fitted one never againCheers gasman, I do suspect the fan, the boiler is only 2year old and the quality of water is fine.
the only time i'd recommend a vokera is if youre not doing a powerflush, the tubes in the heat exchanger are 3 times thicker than a vaillantI've had this problem on start up on fitting 2 previous vokera mynutes VHE's, you think its mostly down to sludge in Heat Exchanger? it does sound like the fan mind you, I know they are crap boilers but we don't get paid to powerflush or anything before fitting them.
