Radiator with cold central area Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

I have a radiator which only gets hot around the perimiter. I am fairly sure that this is a recent problem. I have tried to bleed the radiator, but no air comes out even after some time of keeping the valve open. Any suggestions as to what may be wrong?

Hi Mcd,

Did any water come out?
Did you bleed the rad with system off?
Boiler make/model and system please
