have appropriate rad sizes for the rooms, and the system is balanced.
Balanced?
I have always assumed there was no need to balance a system, where TRV's
are installed.
Many CH installers would probably argue that is the case... but it can
make a system less nice to live with. Especially if you have rooms that
don't get adequate flow until nearly all the other rads have throttled
on their TRVs, or worse, never get to set temp because the main stat has
turned the whole system off.
