Hi, I don't think this has been dealt with elsewhere but I'm new to this forum so please forgive me if it has. I have a newish (less than 5 years old) radiator that just doesn't heat up, although it used to! It only has standard valves and the entry valve gets hot (sometimes). I've tried bleeding the radiator and water comes out striaght away. If I close either value, the water continues to flow, so I don't think there is a blockage. I've tried turning off all the other rads but still this rad doesn't heat up. Any ideas?
