By the way, Dave, you have read the Balancing FAQ haven't you?

I have, but I'll read it again.

I've got 3 CH zones (z1=5+2 rads on different runs, z2=7 rads, z3=4
rads), one zone for DHW, the zones have very different pipe runs and the
DHW cylinder is next to the boiler. It should be fairly easy to balance
rads within a zone but, if I balanced just with the lockshields, I
thought that the different zone impedances would mess-up an overall
balance and the zones with the lowest impedance would dominate until
their TRVs shut down. By equalizing the zones I should be able to get a
better balance.

Where is my thinking screwed-up?
