Not all Rads getting hot

[RoryD]

so many things to check, do they get warm upstairs and not downstairs? Is it that there are some up and some down?? I'd be looking at the pump, whether the by-pass is set correctly or if there's any blockages

only certain ones get hot upstairs & down

if it didnt work before it sounds like you have a problem in the basic design of your system you need two motorised valves and probably a balancing valve on the cylinder get the controls sorted then you can repipe properly sorry failure to read complete thread controls look fine now
