Results are in. Heating engineer has checked the boiler, somehow the flow vale had been knocked and was almost off. Reset to correct position so now working fine. Thanks for help, there was some really sound advice which really helped.

Sooooo, 10 ltrs took approx 30-40 sec on feed and return so that sounds pretty good. While about it i replaced isolator with full bore valves anyway. Let 20 ltrs flow through drain valve for feed and then flow with TRV locked on the other rads. So should be no air trapped ive got good flow on...

Its a standard 1000mm double

Hmm that is a good point, have to say i didnt fit the original so it did work with them on before but i did replace with screwfix isolators, perhaps me being nieve to think that would not effect it... take on board the miss alignment. Ill check they are fully open when i flush it next. Is there...

I dont know the lay out, the pipes disappear into the ceiling. What i do know is the water needs to be pumped to the upstairs rads then back down to this rad and the same back to the boiler, hence if the pumps performance is impaired, its that rad that would be impacted... Is my logic anyway...

I was thinking to myself when i thought it was just a sticking TRV how dull, i soon moved on from that! I actually replaced the rad as it was pretty old so thought it worth it while in pipes were off. But as for the rest, not abit of it!

Cant verify that easily but what i can say it is an old set up thats worked for a long time, it had a combi installed 18mths ago and until now worked... Hence the head scratching

Thanks, yes i kept the pressure in the system at about 1-2 bar. I had a similar thought so i let the water flow each side for a good few mins, i could hear there was air, once gone i thought it would fix the issue but still the same. Air would be a possible cause but ive bled the rads to death...

1 Radiator not working, checked some forum tips and Ive ended up replacing Radiator, TRV and Lock Shield, as they were all very old, this did not help. There is an isolator on feed and on return plus a drain valve in between. So I shut the Isolator on return and opened up the drain valve and...
