I have the same hotblast 1300. Our house is 1150 square ft not counting the basement, where the furnace is; house built in the 1950s. Our house is always 70-75, even when 0 outside. I am sure there are more efficient furnaces out there, but I got mine for like $800 or so to my door. Haven't used our oil for heat since I put it in 3 jan ago. I can get 8-9 hours out of the right load of wood
