Hi All,
My hot water cylinder seems to be running out of puff. After an extended period of heating (when I would expect it to be full of piping water) either by the boiler or the immersion, it is only hot at the top and is progressively colder down the cylinder. It's an old tank so I'd expect a build up of scale by now but it suddenly seems to have got much worse. Is this time for a new cylinder or does anyone know some tricks?
Thanks,
