I know this may be too open-ended a question, inviting a gazillion opinions, but here goes - We are building a new house (fairly open floor plan, 2400 sq. ft. on main floor with full walkout basement and an upper half storey of one big room 24x35; 9' ceilings throughout, very tight and well-insulated) We are used to burning wood and understand seasoning issues, etc. We have a wood furnace in our 1984 home that does a fantastic job. We are putting in geothermal in the new house, but really would prefer wood heat to carry the brunt. (Old ways die hard! Everyone brags up geothermal, but we are great believers in burning what is free out there) We are in NE Missouri, so it isn't like Minnesota, but still gets pretty doggoned cold. We want a ZC fireplace on the main level - something not unattractive that will add that ambience of a wood fire but something efficient as well. The more we've researched, the more confusing it gets! We think we've got it narrowed down to three options - the FPX, the PE FP30 or the HnG Northstar. Each has strengths, of course... any opinions on the different chimneys these units use? We understand that both the Northstar and the FPX use the cold-air cooled (and less expensive) style and the PE uses the Simpson insulated ($$) kind. We are clueless about this issue - any feedback? The looks aren't really the most vital issue to me - though the Northstar and FPX are certainly more attractive. Are we ignoring some brand out there that we should be looking at? thanks, guys, I really appreciate your feedback... one added note - we are getting a heck of a deal on our PE (basically dealer cost) thanks to a great friend, but we're trying not to let a $1K difference make the decision for us as we plan to use this unit daily. We don't want to be sorry daily!
