correction onn my last got warm water not hot lol should i remove the lockshield valve and try flush it. when i flushed the rad i did get black stuff coming out but flushed it for about 15min shook it etc etc til water was clear.

Remove head from TRV ensure centre pin is up ie valve open. Then slowly open lock shield half turn at a time till heat from TRV pipe starts to warm radiator

If you have a combi boiler like us, and it as lost water due to a leak*, like us, then the system wont have the pressure to push around the system. Like us.







*or by beng bled several times!

Remove the radiator again. Then open each valve one at a time to ensure that you have a good flow from each. Obviously place a tray or some receptacle to receive the water from the valves
