can anyone help please. Problem only occurs when the weather is very cold like now. The boiler fires, fan works etc. Then a few seconds later an auful vibrating noise, the fan stops as does the boiler. But th epump keeps working. Only installed 6 months ago the installation guys just tells me it is a known fault but offers no solution or other help. Lots of electric heaters everwhere but would like to have heating and hot water at the moment we have none.
Thanks
Paul
