That is two cords.
We use 2-3 cords a year of mostly cottonwood with some elm, ash, apple and walnut for "overnighters". Our house is 1500 sq ft, built in 1933 and also hardly any insulation. We have a Vermont Castings Encore catalytic stove.
The differences are, of course, we are in Colorado at 4800 feet, and two cords of oak equals probably four cords of cottonwood. We both work weekdays so we use our radiant heat when we're not home. If we were home all day (as in retired, soon I hope), we would probably use 4-6 cords a year, but almost no propane.
I only have a little over a cord up right now, but I cut and split all through the winter. I would rather cut and split wood when it's 40 degrees and sunny than when it's over 90, so I don't even start on my woodpile until October.
Sounds like you have plenty of wood with your backup, but time will tell.
