I got here by asking the EXACT question the OP asked (OVER FOUR YEARS AGO).
Thumbs up to Jeff Marchand. I agree completely. I love the concept but not willing to risk losing my home and all its contents that took me a lifetime to accumulate.
Jeff Darrington I love your passion and believe it is in good spirit but you sound like one of those guys telling people they don't have to pay income tax or don't have to obey the law when they go to court because there is a flag with gold fringe in the courtroom...LOL
Truth is an insurance company is NEVER gonna agree to insure something that a homeowner fabricated themselves. Even if you got some version of this certified there would be so many variables and expenses in engineering (the stove AND the structure) that I just don't see it ever being cost effective.
