I have a problem with all my radiators, the outside edges of the radiators are hot but the center of them remains cold. This is constant to what the boiler is on or the thermostat. I have tried to bleed the radiators but there is no air trapped or if there is (in the center) its not coming out. If anyone has any idea i would appreciate the help.

Blockage, or balancing problem, or poor circulation

Close a few and see if the rest get better. If not you have a sludge problem, and need a power flush. There may be a system problem causing the accumulation.

Did you get this fixed as i have very similar issues with mine. Downstairs are 90% cold only the very top and sides ae hot. I have a single pipe system and back boiler. Closing upstairs rads which have the top 60% hot , does not help the downstairs ones heat up.
