This is exactly my life. 1600 sq ft. Supplemental only comes on if it goes below 62 inside which only happens when it's below 10 at night and I go to bed early. It never gets cold here anymore (which sucks I miss winter) so I'm only using like 3 cords a year...iirc last year I used about 2.9 or so. A cold winter would be closer to 4 cords.
I could lower the supplemental heat to 60 or even 58 but then it becomes laborious to get the house back up to temp. I prefer to spend a little bit of $ during cold snaps to start the am from 62 at a minimum. It really only comes into play a handful of nights a year.
Last year it wasn’t as cold this time of year, I feel like the last week or so has been much colder than last year, and the temps in the forecast after this weekend seems to be colder than a year ago also, had a very mild winter last year based on my gas usage (used most in December of ‘22).
Cold winter would be closer to 4 cords more than likely and mild winter probably 3.
