Are these referred to as something else too? I have an old broken one which I need to replace and cant find them for sale anywhere under this name? Any tips on good suppliers of them too? Many thanks.
Is the scale buildup something I can check for and clear myself? Just taking the front off the boiler I can see there is quite a bit of white powdery stuff. Are there any vents or anything this could be blocking?
My boiler has always been quite noisy but recently it keeps on turning of after about 3 or 4 minutes, pilot and everything. I light the pilot again, it fires up for a few minutes then "click" an it's all gone off again. Any ideas please?
