Thanks! I think it's mainly self-inflicted (I could run the heating for more than a couple of hours a day, and could turn it up considerably higher), but I'm used to it.

My toes were exceedingly cold when I was cycling to market this morning, though; I considered coming home and immersing them in a bowl of hot water, but by the time I'd unpacked (and chopped, and frozen) all my purchases they seemed to have warmed up again. There's nothing like going outdoors to make the indoors feel warm! (Especially when you've left a baked potato in the oven...)
