Thermostat location affects the timing of heat delivery and a blanket
statement about the location of the thermostat not mattering is
misleading. You are not clear about what you mean by an incorrectly
sized radiator. Steam radiators do not come tailor-made for a room
and there is always adjustment necessary at the time of installation.
Modifications to the house, such as adding insulation, will also
require radiator adjustment. Most steam radiator problems can be
compensated for by adjusting/replacing the existing steam vent (or
adding another one), adding an air eliminator to the too-slow-to-heat
main steam line on that side of the house, painting the radiator or
building a radiator enclosure. All of the factors are interrelated.

What you're saying is correct, and the point I'm attempting to make. If one
area of a heating zone is hot, and another cold, relocating the thermostat
to the location that's cold, does not solve the problem, adjustments to the
heat output of the radiators does.
I guess when you pay nothing for a news reader, this is the result.

Why do you want to zone, is heat uneven. I dont think its worth
considering from a cost point, I use Danfoss thermostatic valves.
Uneven heat is a Vent issue on radiators and the returns, Vents do go
bad, I balanced everything with venting.
