No work done - just switched on again after the summer - suspect your right and its an airlock but not sure how to deal with it. After reading previous postings tried shutting off working rads and setting pump to max. This seems to have cleared some of the upstairs rads one by one, but one of the previously working rads downstairs now gone cold...
Now have 2 up and 2 down that are cold and can't seem to clear them. Other 9 are ok.
Any further suggestions please chaps?
System is open vented - feed tank seems fine, Potterton Kingfisher2 boiler, Grundfos pump UPS15-50 130. Hot water fine.
