Central Heating Radiator
I have a radiator which has been turned off for a long time. It is now turned on. How long do I need to wait until it gets hot. The input pipe is hot and the output is also hot but all the radiator water is cold. Do I need to bleed off the cold water or just wait?

It can happen that, if the pipe runs from rad to main circuit are very short, heat is conducted along them rather than any actually flowing through the rad.
The TRV is the first thing I would go for.

thank you all. I had turned on the input valve with pliers without success but as Builder said I removed the cover of the control valve to find the pin was loose. So I prised off the plastic cove of the input valve to find it had stripped and not turned the control nut so I tuned the but with a spanner and lo and behold I have a not radiator. I pushed the plastic cover back on for cosmetic reasons and that was that. My advanced age seems to have prevented any sensible thought and I'm not sure what to do about that. Obviously try the answer bank and jog my grey cells. Thanks for all the advice and all have a festive Christmas.
