Radiator cold on bottom???

    Was bleeding the rads today (as I do every couple of months) and one of the radiators is cold on the bottom and hot on top. I know if they're hot on bottom and cold on top, I just bleed them and this equals things out. But I've never come across this before, and bleeding doesn't do anything.

    Anyone any ideas/suggestions?

    Thanks a mill. :D

    Sounds like it could be sludged up . Is it an old system? And why do you have to bleed them so often ?

    The house is about ten years old, if not more. We usually run out of heating oil once a month as we don't always have money to top up. So when we get a drum or two of oil, the system has to be reset every time and it causes airlocks in the system. I know it's not ideal, but sometimes can't be helped. :o

    Running out of oil shouldn't cause airlocks in your heating system , sounds like you have a leak somewhere to me . Constant bleeding of system and introduction of fresh oxygenated water will corrode the system and cause sludge build up .
