I currently have the 17vl England's stove and was planning to get the bigger 13nc. Love it, just undersized it. I thought I made the right decision but it' just not big enough. Also it doesn't have a long enough burn time for me. I get 4 hours or so on good wood. I live in a basically uninsulated 30's home around 1100 sq. Ft. My question is, before i do anything, would the 30 run me out?
