Don't be so quick to keep warm air away from windows. There are
reasons houses are designed with heat sources under windows.

1. It prevents condensation and the accompanying mold, mildew and
water damage.

2. It prevents a "drafty" feeling when you're next to windows by
ensuring the windows are warmer and thus giving off almost as much
radiant energy as interior walls.

Yes, it wastes some energy, but if you're that set on saving energy,
look to newer windows.... although I won't guarantee you'll save money
in the effort.

Where do you get your information? Heat sources, as you call them,
are NOT installed under windows for the reasons you mention.
Radiators, either electric or hot water, are installed on OUTSIDE walls
because of convection.......Cooler walls cause the warmer air to rise,
which in turn, cause warm air to circulate.
