Hi. I have an unusual (I think) issue with one of my radiators.
Since I moved into this property 18 months ago the radiator in the kitchen (next to the boiler) hasn't worked and I have only recently attempted to sort the problem.
The pipes coming to and coming from the rad are not getting hot either.
I have tried everything I can think of to no avail.
So far I have.
Taken off the rad, took it outside and flushed it through with a hose.
Replaced the TRV with a new one.
Replaced the lockshield valve with a new one.
Turned off every other rad at theockshield and turned the heating on in an attempt to flush the system.
The thing that makes it unusual is that when I undo the TRV at the tail or the pipe, even a little bit the pipe starts getting hot as does the radiator. As soon as I nip it back up it goes cold again. It does this with the old and new TRV.
Any help would be greatly appreciated. Thanks in advance.
