And twice as expensive as an ac system as only the refrigeration plant is required.
Not for the de-hum & re-heat, nor any local re-heater batteries.

the idea of putting rads under the window is an old one. With draughty old single glazed windows there, the heat loss is highest, so the maximum heat goes straight outside to warm the sky.
If energy was free you might not mind.
It also prevents you having long curtains.
Modern glazing and curtains mean that the cold area next to the window is not such a problem for comfort now, but it is still the worst place for energy loss. A rad on an internal wal is better for comfort throughout the room.
This study proves you are correct about the extra energy loss associated with placement of radiators under windows.

I rest my case.

It makes no mention of the very valid reasons for placing heat emitters under windows
I am in the process of stripping out my bungalow completely and thinking about where to position things..
So thinking about the radiators I was always under the impression they should be under the windows for best efficiency and comfort but mine are all currently on the inner walls..
My guess is that this is because the central heating system was retro fitted at some point and it was just easier to drop the pipes from the "middle" of the house than at the edges where there isn't much space to work in the loft..
Should I try and reposition the radiators to the outer walls under windows when I get the heating sorted or doesn't it make much difference and so not worth the hassle (and probably extra cost)??
Spot on!In the well insulated new builds they never bother with rads under the window!

Traditionally radiators were put under windows to combat draughts, in the days of leaky, single glazed windows. However, this does increase heat loss and is energy inefficient. Also, they get in the way of curtains.
I think modern and energy efficient practice is to install radiators on internal walls where possible, but of course a lot of people still do things the way they have always been done... because that's the way they have always been done.
