Thanks for the help on this. I will get Thermometors and try that. Not sure if his matters but the pipes at either end of the cold rad are cold aswell. It was working fine a few days ago untill I bled a red in the bedroom that had a lot of air in it.
Hi
I just moved into a new house. I have one cold rad in the livingroom. When I close all the other rads in the house the cold one heats up. But when I open them again it goes cold again.
Anyone got any ideas?
