More to the point why is the 13 NCH an EPA certified stove and the 12FP is not ? Which stove is better ? I plan on heating my 600 sq ft basement and my 600 sq ft first floor . I plan on using bio bricks which I can but 1000 for $ 150.00. Also plan on using some cord wood. Why is the 12 FP a 35- 1 stove, and what does that mean ? I plan on running my exhaust pipe up 3 feet through my basement wall and up the side of my house . I don't want to build a chimney so I plan on using that shiny stove pipe ,don't know what it is called . I do not want it right next to my house so I plan on having it about 12 " from the outside wall . SOOO does this sound like a good plan ? Or should I get a better one ? Any help would be great . Home Depot usually run a half off sale on wood stoves around mid February and I plan on buying one at that time.
