Been meaning to balance my radiators for years. Gave it a go once but
messing about with fiddly thermometers did my head in. I tried a digital
one and clip on ones. Anyway while in the bath last night I came up with
a new method.

Why not by one thermometer, common or garden variety, for each radiator.
Place one thermometer on top of each radiator. Wait 15mins then do the
normal lock shield valve adjustment cycle until all thermometers read
the same.

Do flow and return temps really matter that much? Surely if the
radiators are the correct size for the room and they are all giving off
the same temp then they must be balanced!

Awaiting replies with interest!
