Burning Hunk
Chimney is about 15 feet i think but never actually measured, its centered right in the middle of the house so no exterior to wick heat away, 6 inch insulated flex, block off plate. Ranch with about 1,550 SF upstairs and a fully finished basement. All the furnace air return vents are in the stove room or hall right next to it. I leave the blower on the furnace on but the burners shut off, and have all the upstairs air vents blocked off with the down stairs vents wide open. It hasn't been super cold yet, down in the teens once but it was easily able to keep the house (including basement) in the 70's, and would go about 8 hour reloads with sub par wood from last year. Won't know for sure how its going to do till it gets down to single digits for a few days straight and i start burning the good hard wood. Its in the 30's here now and I am doing two loads a day without issue though. Keeping 72-77 in the stove room.
