could anyone have a clue as to why it only ignites fully on hot water demand. heating side goes through a continuous cycle of lighting then going out. it`s a mate of mine who owns the boiler, so no pressure or anything. plus his mrs scares the hell out of me and she`s cold. bad times! any help on this would be appreciated, cheers. and for the record, i am an rgi. just a bit stumped.
