It doesn't get that cold here - it hardly ever goes below freezing - but it is a damp cold, which makes things feel colder, so you do tend to run the furnace a fair amount.
But since we got the new windows, the house has held heat much better, so the furnace only runs a bit in the morning - at least so far.
And now that it is getting cooler, I'm starting to appreciate how a gas stove can keep the kitchen warm. In the summer, I wasn't so sure ;-)
