I've been researching pellet stoves to find the one that best fits my needs but I'm not sure what to look for and am going a little crazy trying to figure it out. I've been looking at Breckwell, St. Croix, Englander etc. I've heard that Harmans are the best but a dealer told me they are all sold out in our area. I have a two story 1600 sq ft house. What questions should I ask and what should I be looking for.
