this problem is probably due to a build up of sludge throughout the system. The sludge - black iron oxide, is caused by corrosion on the inside of the pipes and radiators, resulting in poor circulation of water. The system needs to be thoroughly cleaned with a special chemical. There is a sludge removal liquid available. Add the liquid to the feed and expansion cistern. Two days later it will be necessary to drain and refill the system. OR you can change the radiator...glad to help.
