In our current house the radiators are under the windows, which annoys me as you either have nice long curtains that block the heat, or naff short ones.
We're moving to a Victorian semi in the new year and I've noticed that the rads are in the same place, but the heating system is old so we might be replacing it soon. Where's good for radiators? Does anyone have those stumpy little skirting board ones? What about underfloor heating? (can you do this in old houses?? 
Arrgh, I hate being cold but I hate short curtains more...
