For balancing, quickly go round all the rads with your IR
thermometer, and note the flow and return temperature of each one.
Then start turning the lockshields down on the rads with the
smallest temperature *drop*. Remember, you're aiming to get the same
drop on all of them - and you do this by restricting the flow
through the rads with too low a drop.

A good summary, I may borrow that ;-)

Thank you - feel free!

It's a good practical method which always works without needing to carry out
any complex analysis of the system.
