Gasifying wood furnace

FWIW I found this 'gasifying' furnace while looking at wood sauna stoves.

Kuuma Vaporfire

The price isn't too steep, computer controlled combustion and American made. It might be a good option for those that can't go the hydronic or radiant route.

That is pretty cool, Burn-1. Thanks for posting the link.

I've always wondered about gasification furnaces. Seems it would be easy to do, but you have to deal with some pretty hot temps. I'll have to check that out and see how they handle it.

Very interesting; heats 2600 sqr feet. I wonder what the "to the house" efficiency is like compared to boilers. Anyone know? I am going to email/call them for more info. j

I guess heat storage would be the interesting part. I can't think of how you'd do that, but there probably is a way--maybe with some sort of refractory mass. Probably not built into the furnace.

Does anybody know anything about the testing lab, http://www.pfscorporation.com/public/, that these Kuuma Gasification Stoves use? I haven't heard of them and when I go to the website I didn't find much about stoves?

I see they are made in Tower Mn. Cant think of a better place to test the product, other than Alaska. Tower holds the state low temp at -60 back in 1996. And overall is one of the coldest place in the state on a regurlar basis.

Well its -35 F here but I'm only an hour or so from Tower. This Northern Minnesota Winter has been just brutal.
