i have a 2200sq ft home i burn about 2 1/2 tons maybe 3 and trust me when i say the house is 70° sometimes 75 lol. at night i put it down to mid low 60s. i have a split, first levels is a bedroom/bathroom, laundry room, mid level living room, kitchen, dining, up stair 3 bedrooms and a bath. down stairs gets a bit cool but i turn base board on low and it maybe kicks on a few times a day. the upper level is always hotter so the warmth down stairs stays down there pretty good...
