Why? Surely if your boiler is powerful enough you don't need to mess around
like this. If your boiler can't heat all the radiators at once, your boiler
is too small for the system. Even with all my radiators on full blast, the
boiler doesn't run continuously.

Yes you do, Lootenant. Otherwise a rad nearest to the supply can
short-circuit all the others.

Then that room will warm up first, that TRV will close first, and
then the other radiators will warm up. If you want to get everything
to warm up evenly when the TRVs are open you need to balance them all
carefully, but it's not as essential to get it right as it was before
TRVs. (On the other hand if the radiator closest to the boiler is the
room you care least about, it would be silly to ignore it altogether.)
