We shut ours totally off two days before we went to PEI, so September 21, and haven't touched it since.
Our gas bill this month was $26 (gas dryer and range)
Our electrical bill this month was $73. Our house is 1970 sq foot so quite good!
We've never gone past Oct 27 without turning on the furnace. It's never dropped below 65 in my house yet and doesn't look like it'll be light jacket weather for at least two more weeks. Where are we are hottest October ever?
I've also had .03" rain in the past 40 days. It's drier than a bar on BYU's campus.
