Thanks for the link, I have always thought that if I would love to build a house and incorporate a stove with some other thermal mass quality's. Like a I saw one that the exhaust was routed through a huge rock wall and another that went through a stone bench.

Man has spent thousand of years working to keep the women thawed out.

Pretty neat. The original tromb wall.

That's funny ( thousands of years in wasted effort trying to thaw a female out). Two little words (I do) make them impervious to those attempts.

Are you saying once you say "I do" she says "Oh no you don't".

The one that went through a stone bench is called a rocket stove mass heater.

Very interesting concept, small fuel, run wide open, radiates heat from the thermal mass for hours after.

So far the main problem with rocket stoves is burn time length. With out the mass to absorb and then slowly radiate the heat you have to be there to pretty much constantly feed them every hour or so - There is one unit ( Liberty) that they have added a gravity pellet feed to to get a longer burn time , this slightly different than the one that was created on the west coast and subsequently sold to USS Stove a year or so ago. ( I can't remember the name of that one) I was interested in it until it was sold to USS, as I will not deal them ever again.
