I have a Hearthstone Manchester in my newly built, very tight, cabin style, open floor plan home. It is the warmest, best running stove I have ever had (jotul black bear, Mansfield, etc). Out house is 1800 sq ft, 1400 if cooler bedroom door closed. This thing will heat our house from 68 (FHW setting), to 78-80 in a bit over an hour. It's mainly convective heat, but also some radiant due to the interior soapstone. Outside is cast iron. I'm actually considering selling this and getting a new Jotul Greenville F45 because we are just too warm....I know...l know.....but I like keeping smaller hotter fires going rather than starting a fire once every 12-14 hours because it's just too hot in the house. The Manchester is what I would get in your shoes. Take heed to the advice someone gave about east- west loading with a front door only model....nothing compares to north south loading, no roll outs or logs falling against your only door. The Manchester has both, can order side door on either side, and it takes a full 24" log.
