That's certainly less. I bet Op could get away with 4 to 6 then. Subject in my post has a large 5br old farmhouse style place, also heats house, water and garage off same unit.
One of the richer men around here a century ago had a mountainside castle. He burned a hundred cords a year. He has a single employee who cut, hauled, split, and fed all of that. In the summer me also mowed the lawns.
And his central heating system was considered to be state of the art.
