Do you leave the central heating on all night in the winter?
On all but the coldest nights ours is programmed to go off between midnight and 2am and then 3.30 to 6am.
All our guest rooms have 15tog feather and down duvets, plus extra blankets (which rarely get used) and no-one has ever complained of being cold int he night.
It seems a waste to have the heating on whilst everyone is tucked up in bed, so I wondered what others felt about this.

...I would freeze to death before making it back to bed.
