Cold weather Jellies: Do you have a date before which you will not turn on the heat?

It’s pretty chilly in the house at times the last few weeks but I’m determined not to turn on the heat until 10/15 at least. It’s a fairly arbitrary date and I have used the gas fire to sit by in the mornings.

Wondering if anyone else waits to turn on the heat and if so, when. Bonus question: Am I saving money by using the gas fire some instead of the heating system (also gas)? (That’s one for you, LuckyGuy – our BTU boy!)
