Right I have a problem with some cold rads:
The rad in the Lounge, the one in the Hall and downstairs bathroom are stone cold. However, the rads in the dining room, conservatory and 2 in the kitchen on the same floor get hot.
All the rads upstairs apart from 2 in the upstairs extension get hot, the 2 in the extension get warm.
I can feel and hear the pump operating and I have tried to bleed all the radiators (a small amount of air came out of one of them). What can I try next?
