    sounds like an airlock ?

    are u getting water out when bleeding ?

    can you close off the other rads and see if that pushes the air along ?

    Have any rads got a drain off on ,if so attach hose to this with jubilee clip and the other end to outside tap turn on slow to push air to header tank this will alleviate the problem.

    likewise if ur rad has a drain point then connect a hose and drain for about a minute...this could do it without the danger of overflowing in the loft (if warning pipe has a problem)

    Few years ago experienced a similar problem. Removed radiator again and replaced it with clear plastic hose connected to 1/2 in tap connectors which matched the radiator valves. There was no flow through the plastic pipe. Then removed one end of pipe and placed in bucket, opened valve to allow bucket to fill and out comes water plus air. Close valve and repeat for other side. Tried heating again. This time water flows through pipe but did contain air bubbles which finished up in radiators.With valves closed and pipe removed, radiator replaced problem solved.
    You can try increasing pump speed and boiler temperture if you don't like the above.That might shift it.
    It would take for ever to get rid of a air lock via a bleed valve and it's highly likly the air can't move along to a radiator due to the resistance. So it makes sense to release the resistance to get rid of air.

    The bleed valve has broken off so i undone 1 of the caps on top of radiator i could hear air but couldnt see no water moving about this house is 3 storeys high 2 rads on top floor these are ones that dont work and neither has a d.o.c on them
    Can i still put hose on 1 on bottom floor
    I was told by a plumber friend to turn all radiators off in the house then open the 1 with a problem as this would push air out

    i take its a pressurised system to get ch water up there. have u closed off all other rads to see if air is pushed along ( as per my 1st suggestion)
    is the system pressurised ?
    u must have water in the rads...so make sure the system got some pressure.....say 2 bar and go upstairs and undo the cap till water comes out..
