Hi all. I've got an old vented system. The tank is heated by an oil boiler - or was at least! It started cutting out shortly after firing, then stopped all together. I could hear alot of noise in the pipes so suspected air in the boiler to cylinder loop. Cracked top but to cylinder and nothing! As in it appears empty! But, how to fill?
