Anyone got any thoughts on this? We've just moved into a new place and all the radiators work fine except for one. It's stone cold, while the others are all blasting away.
I've had a look at the valve on the base, removing the little white plastic cap and using pliers to make sure it is all the way open. No effect. What else could it be? My 7-yr-old son would appreciate your answers, as his is the unfortunate bedroom.
