came in tonite and the radiators that were cold this am were now hot and 1 upstairs was cold so bled them all and everything is hot could it just have been an air lock as quite a bit of air came out

sounds like an intermittent fault with pump - the impeller may be loose or could be getting stuck - replace pump and all should be fine.
