Hi, I have a problem with my radiators. I have just turned on my central heating for the first time this year and the Radiators are not getting hot. The bolier is a Baxi Bermuda 552, and I have checked this and the pilot light is on, and the bolier 'Flares up' every few minutes as normal, but the radiators do not heat up. Can anyone help? A similar thing did happen last year and on that occasion the "father in law" who is a Gas man fixed this, however he is no longer around and therefore can not ask him.
