What a great website to get real knowledge about wood burning gasifiers and other options. Here is my story: Our family purchased a log home last year that is 13 years old. It is a large log home (and needed a lot of work) at 4600 sq ft with 2 forced air furnaces (one in the basement and one in the full attic). My propane cost this past month was $1,000! Something has to change. I have not burned with wood in the past, but have been researching different types from fireplace inserts, OWB and gasification boilers. My basement is a play area for the 5 kids and has easy access through the garage and enough room for a storage tank, or I could put the boiler outside. I hope to fuel the 2 furnaces, water heater and someday my dream gym (pole building) of approx 6000 sq ft. What advice does anyone have about a system that would work best in my situation? Thanks!
