Yeah. So what? at least it comes on eventually.

Well, in my case, it's the kitchen that comes on last as it's the furthest
one from the boiler, pipe run wise. And that's probably the second room
you visit first thing...

Basically because the ones nea the boiler where the ones I wanted to
get hot quickly anyway...eventually the remote bedroom ones would come
on...

I can't quite follow your reasoning. A well balanced system can do without
TRVs altogether. Adding them to one which is, is merely the icing on the
cake. Using them to cure an unbalanced system is a bodge and serves no
purpose, given that anyone can balance up a system given the inclination.
