i had a full central heating system installed 12 mths ago.When i put it on this winter 2 radiators downstairs were cold after balancing them they worked.The next night we put the heating on again and this time 1 radiator was cold,when i turned the thermostat on the radiator down that was cold and then turned it up again after 5 mins it became hot.Do you know what might be causing this problem.
