By your description, the radiator is full of sludge which is preventing the hot water from circulating properly. It needs removing and flushing thoroughly with a hosepipe.

Hi,

Cold at bottom indicates a sludged up system. Do you have any chemical in it?
If not, bearing in mind your forum name, I suggest you call a good RGI.
May need a flush out or two + chemical - inhibitor.
