The old theory, with sliding sash windows, was that you open them a little so that fresh cold air drops over the radiator (i.e. convector) is heated up and provides a pleasant warm temperature. The stale warm air which has risen to the top of the room exits via the top opening.
That was before we tried to conserve heat.
In practical terms, if you need to put furniture against the other walls, the space under the windows may be all that is available.
What you shouldn't do is cover the radiators with floor-length curtains. Unfortunately that is exactly what Mrs P likes and then she complains about the cold. ??
