Before the heat proof window pan era, locating heating radiators below
windows was a must because it generate a courtain against heat lost on
widows surface.
Such heat air courtains are often used today for very large open doors
(no windows, just the open door).
Now this perspective has changed as long there are available windows
systems with 3 or 5 glasses, with less thermal loss than the wall
itself.
