Confused here. I'm trying to bleed radiators in a vented system after draining and refilling. Oil fired boiler is downstairs but pumps hot water upstairs first. It looks like downstairs rads are then fed from upstairs. With me so far? All rads filled okay (and bled) from header tank but when I put boiler on, didn't get any hot water to any rads (or inlet pipes). Pump is pushing hot water up the pipe from the boiler and return to boiler is warm (although I think that could be from DHW side of things). Have managed to get 2 rads working upstairs by a combination of bleeding and sucking water out. Am I just going to have to persevere with this or am I missing something obvious?? Thanks for any help.

If you are sure you have bled the system try closing the valves on the rads that work - this may help remove any air (if this is the prob), also bleed any thumb vents in airing cupboard and try bleeding the pump(when it is switched off).
