System needs balancing and could still be full of sludge.
im not sure how to balance the system...nearly every radiator is different!!!!!
They're still full of water and they still have two valves... one for setting one for balancing.
Choose your setting valve on each rad and open it fully.
Now close all the other valves then open them a half of a turn.
Now run the system for 30 to 60 mins and see which are hot and which are not.
Those that are blasting turn down a quarter of a turn.
Leave for another test period.
Those that are still not hot open another quarter turn.
Repeat test period.
adjust each rad in turn in 1/8 increments until the system works or you are board.
If board call and engineer 'cos your system is clogged and the pump is probably suffering.
Once the rads are all hot you can worry about temperature drops and the like.
