Lets say you're in apartment building with a lot of units. You're in
the first apartment. You want the room colder, so you open the
window. The room now has colder air, so there is greater delta T
from the room to the radiator. The radiator loses heat faster, and
cools to a lower temp (lower room temp) so the next guy gets colder
water. And, the water going back to the heating plant is colder,
also. So they use more fuel. See? Opening windows does at least two
bad things. One of which is to cool the water that the later
apartments need.

This assumes there is 1 continous loop. Highly unlikely, don't you
think? Probably the loops are for individual units, from a main
central loop. So your return (colder) water does NOT have to heat
someone else's unit. But the same reasoning for covering the
radiator rather than opening a window still holds - total heat loss
is less, and so operation is more economical.


So what are they missing in Siberia? Why are they still opening
windows and not issuing radiator covers to all comrades? Maybe someone
in the politburo should subscribe to usenet and start reading a.h.r.

I hope you aren't literally asking me to asnwer that question grin.
Perhaps it is because such a steam(?)-powered system is very efficient
and cheap to operate (there are systems like that in other places too,
such as parts of NY City). Perhaps it is there, and the fuel is rather
cheap (Russia is an oil- and gas-exporting country, big time).
