Double rad, one side cold at top.

    Just moved into a house, all rads fine apart from one.
    It's a double, one side is fine, the other is hot at the bottom but cold at the top.
    I presumed it would just need to be bled, but the bleed valve is on the side that is hot.
    Any ideas?

    Have you 'bled' it? Was air coming out? Is the radiator part of a pressurised system - what is the barometer telling?

    There will definitely be a second bleed screw for that panel also. It may be covered over with a plastic cover which needs to be removed to reveal the bleed screw.

    Checked it again there, looks like there was another bleed valve, but with the head broken off.

    You can buy replacements from any plumbing suppliers. You will need to remove the radiator by turning off both the wheel valve & the lockshield valve. Drain the radiator and remove it from the wall. With a compass pin or similar you should be able to start the bleed screw to turn. They are usually not that tight. Replace and put everything back in reverse.

    If the bleed screw if facing you and not the wall, you should not have to remove the radiator or even if it is, you may get it out without removing rad. Either way, turn off the valves to give you chance to put the new screw in.

    bleed screws dont break off cause they are loose...

    option1. remove radiator as above. use oxyacetylene torch to separate 2 sides of radiator. drill out and remove bleed valve completely. weld in new bleed valve assy, weld radiator together, reinstall and pray.

    option2. Replace radiator complete
    option3. Live with it

    easy!

    or save all that smoke damage and simply turn offf valves each side, drill hole on top of rad and fit a self taping screw with a O ring :D
