    Can anyone offer any advice - drained down hot water / heating system completely to isolate some rad pipes (had to drain system as nothing isolated). After filling back up (boiler - conventional not combi - myson marathon 600B) the hot water tank is not getting hot so no hot water - the pilot light is on on the boiler but obviously not transferring through to the header tank. Have advised may be an airlock as common on these systems but have tried to loosen nuts to header tank to get air out but still no joy. Any advice on this would be greatly appreciated.

    You could also look up "blocked feed" and "air lock" on the forum as this has been asked a gazillion times before.

    I think he wants to avoid a professional !

    Probably wants to save the £84 cost.

    Could be a number of things, most likely is either blocked cold feed, (so insufficient water in the system), or blocked primaries. Before undoing anything else, try draining some water off again, and see if the feed and expansion cistern rushes to refill the system.
