Hello,
I have a similar problem - one cold radiator (upstairs, combi biolr downstairs) whilst others are piping hot - but some differences. I've taken off the TRV, the pin is up and the radiator remains cold. I bleed the radiator for about 20 mins and hot water eventually fills the radiator. I close off the bleed point and it goes cold again. The pipes to/fro the radiator are warm.
Any ideas please?
Thanks.
