I've been out for a few hours and returned to find the rad without TRV which I left on now has a warm pipe under where the TRV should be and the rad with a TRV which is on is actually luke warm. This looks like progress. Shall I just leave things as they are for a while?Yes very good keep it going / leave it as is try bleeding the rad to see if there’s any air there etc
Will do. ThanksJust as a helpful tip more than anything, if you have a magnet, try it on the pipes that are supposed to be blocked
Thanks very much. At the moment things seem to have improved a little. I have 2 rads on which were stone cold and one of them has a warm pipe under where the TRV should be (it's missing) and the other one which is on has a TRV and the rad has become luke warm. I bled them both before going out earlier.As Shaun said, close all rads, leave one open. Take trv head off and use a pair of grips to pull out/push in the pin a few times to free up any Rubbish.
Then close the lockshield valve on same rad. Put a rubble sack (something to catch water under the trv to rad connection and loosen the nut a bit (not fully) until water starts to flow out. Keep it flowing until it gets warm (keep someone else topping the pressure up as needed). Then close trv and do it to other side until both flow and return are warm.
Then open both valves/bleed and rad should work.
I never use leak sealer but it has been know to gum up valves.

if you don’t feel comfortable undoing nuts, follow my instructions but instead of undoing nuts, keep bleeding water until pipes get hot. Do one rad/rad at a time.
You need to get the water moving.
Good job buddy.Thanks very much. At the moment things seem to have improved a little.

edit: just as a test I fiddled with the pin of the rad without a TRV and low and behold I heard a release of water and the rad is now fully working. I went and did the same to the other one and it's also working!
We've cracked it boys! Looks like things are resolving. You guys have saved me a packet - I'd buy you all a pint if I could. Thanks a million.
