Under-the-floor heating? You mean never again waking up to a freezing cold bathroom floor? I really like that idea.
Oh yeah! I'm really looking forward to having warm floors! Apparently it's the most efficient type of heating because it gets the heat to the part of your body that is always the coolest. You're warmer up near your head, so you don't need it warm in the upper reaches of the room. Also, if your feet are warm, you feel warmer all over.;o)
