We really want a rocket mass heater, but living in a home with crawl spaces and basement so looking @ woodburner instead. After a little preliminary planning/dreaming, decided to check with insurance agent to see requirements to avoid nullifying our fire protection. He said that woodburner MUST be UL approved and installed per manufacturing instructions and inspected by fire inspector.
So after reading above and hearing the concerns around slow sales, the need for UL approval is a BIG deal for increasing sales. My guess is that getting that approval rating is why the Kimberly(drooling....) or the Katydid fuel gasifiers cost $4000 , add up to a grand for installation extras. They have made this a luxury item, basically, marketed toward the mariner crowd, but its the only rocket stove that has gotten the approval.
Any ideas as to how they achieved that could be very useful in proceeding.
A go fund me page is awesome idea, if that's what's holding this product back.
New to forum, apologies if this is rehashed info/ideas.
