Balancing radiators.
The radiators that are nearest the pump are usually getting hot first. First make sure system is on heating only and any bypass if fitted is closed. They have a lockshield valve one end and a hand control valve the other end, close the lockshield valve with a small spanner on the flats of brass shaft exposed when the plastic knob is pulled of. Then open it 1/8-1/4 of a turn, make sure other valve is fully open Then move rad that is next one from pump and repeat, and so on until you are downstairs then open lockshield valve ¼ -1/2 a turn. That should work all rads. Then open bypass valve to same position it was in. Good luck

radiators have lockshield valves both ends of radiator
don't worry nominate either left or right, preferably the one that is least accessible, and use that as the one you adjust to balance and and just turn the knob, if it is to stiff to turn, lift it off with a little bit of care may have to use a lever under it, then turn with a spanner and continue.

make sure there is water in the header tank open both valves on the rads full tilt and close the others that are working off
