Finally figured out how to really work the smoke dragon in the basement and I am in love with that thing. But, now we're having a new Lopi insert installed upstairs, and the smoke dragon will only have to heat 800 square feet instead of 2400. I know that an EPA stove is more efficient and cleaner, but HOW much more efficient and HOW much cleaner? I hate to replace the smoke dragon since it very clearly works (yes, it eats a lot of wood, but we've figured out 10 hour clean burns and it heats 2400 square feet to 75+ degrees when it's 7 degrees outside). I'm in the "if it isn't broken, don't fix it" camp, but is this thing destroying the planet?
