Many thanks to all who replied when I was last having probs - thi
problem is linked. Previously you all said I had an airlock in th system (Potterton Combi 80 running 5 rads) which I managed to solv following your advice.
However now whenever the heating turns off overnight etc in the mornin the same 2 radiators that where cold before still don't heat up.
These 2 rads are on the ground floor with pipework coming down fro upstairs where 1 other rad is on the same loop. I can shut all th rads to force the water through but i'm getting fed up of doing i every day...
What am I doing wrong???
