I took all 3 radiators off on the top floor of our house a couple of months ago to decorate, but now they are back they are not getting warm.
The boiler (Ferroli Maxima 35C) has also been moved from the Middle Floor to the Ground Floor whilst the radiators were off.
The radiators on the Ground and Middle Floor are fine and get nice and hot.
I've bled the 3 radiators until water comes out of them (and bled the other rads)
The flow and return pipes to the 3 radiators are cold.
The TRV? and LSV? valves are open (is anti-clockwise open?)
Any ideas as its now driving me nuts - is it an air lock or do they need balancing (still not getting warm after CH has been on for hours?)
