My gas boiler is heating up so much that you can't touch it, however the radiators are not heating up at all (Very Cold). I also noticed that for a short period of time (couple of minutes)it did give off some black smoke. We have checked, and the pump is definetly working.
Could someone please advise me what is wrong.
