I was told by a plumber that the lockshield valve on my radiators should be 'just cracked open slightly', from my understanding you dont want the LS valve open too much as the water will flow through the radiator too quickly and not heat it up fully is this correct?
I took this plumbers advice and tightened up all the LS valves on my radiators and then just cracked them open slightly but in doing this i noticed only 2 radiators downstairs were getting hot the rest were luke warm at best.
So my question is how many turns should to open the LS valve and should the last radiator in the CH system have its LS valve open fully?
