Need Advice about Boiler and Central Heating Repair Please

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.

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.

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.

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.

I'm down to one remaining cold rad which is being stubborn but it looks like the pin is not moving as well as the others I've done. Will add some WD40 and keep wiggling and as you suggest also keep bleeding.
Thanks very much

Update: 99% of rads working! 1 stubborn fella left in the lounge but we have a fire there.
Both kids have heating in their bedrooms now. For tonight I've turned everything back on to keep us warm and tomorrow will isolate the lounge rad again and bleed a ton. No need to pay another plumber which is amazing and I'm looking forward to telling the bloke who wants to replace our boiler and pipes to take a running jump.

Also my mrs thinks I'm a genius thanks to you guys

Have a great Saturday chaps.

Good job buddy.

Rather than a beer, if you’re able, maybe do a one off subscription to our forums to help with the running costs! No pressure!
