Why are radiators commonly placed under windows?

I've already posted this item in the "Construction & Self Building & Architecture & Planning" board but I wonder what you folks think. I also hope I dont anger anyone by running the same issue on two different boards.

To stop the downdraft from the cold glass...?

I'm guessing to create a better flow of heat as the hot and cold areas will create better circulation.

Im guessing because its the obvious place to put them. The wall can not be used for shelving, television etc. so slap a rad there and everyons happy. Two birds and all that.

I've often wondered about this. I suspect that the answer is Enda1's theory that its just the most convenient location for lazy builders or house designer/architects. I don't buy the theory that the mixing of hot and cold air streams helps the heat to circulate. Surely it just makes it easier for the heat to escape through the window glass without first warming the interior of the room?

I particularly wonder about the case of floor length curtains which hang down OVER the radiator. This seems to be increasingly fashionable but, in terms of heat loss, surely it is madness.
