Hi
This is a puzzling problem.
My heating system working fine except one downstairs radiator (dining room) not working.
All other radiators working fine All radiators have been bled. As I say all others up to temp. and pressure in system ok.
We turned off the radiator in question in summer to paint. Now it will not heat up. Have opened valve to full, but pipes coming out of wall to the radiator are still cold , my guess is that no hot water is even reaching the radiator.
Any ideas what the problem is and how to rectify it? any comments appreciated.
