Just out of curiosity how is your stove set up?
My stove is in a 600SF apartment that i am remodeling. I have it vented into a Huge 12" flue that used to service an enormous building coal furnace. This is far from a typical setup as venting into such a large flue usually results in poor draft, but it actuall works very well. Draft is fine. I also have an NC-30 connected to the same flue in the floor below but the 2 stoves are rarely run at the same time, but when they are they perform just as well.
My only issue with the stove is i cant get that much wood in it ,but thats the drawback of a small stove.
I burn mostly old wall studs and floor jousts that i tear out during the re-hab. I assume its pine.
