Hi,

I printed out the page from the faq but I'm getting really fed-up with
trying to balance these radiators!

I bought an IR thermometer. I'm holding it close to the pipe to get a
narrow beam but even so, just a slight movement gives a temperature
drop of 10C. I put masking tape on the pipes. Is this causing some of
the problem? Should I be using insulating tape instead?

I use little squares of black tape on a flat surface of the radiators - just
inboard of the valve connections.

Should I start with the lockshields where they are and tweak or should
I start with them all open?

If the system has previously been balanced, and is in a *reasonable* state
of balance, start with them where they are. Otherwise start with them fully
open.

Do you make changes to several radiators at the end of each run or
just one radiator per run? Or do you tweak as you go along?

2 or 3 at the most. Turn down the ones with the smallest temperature
differential.

How long should I wait for things to stabilise before re-measuring?

Probably about 10 minutes - but you need to make sure that the system is
running the whole time - so turn any room stats up to max, and open some
windows if necessary.
