RE: [papercreters] off topic???

Do a search on rocket stoves. Very efficient way to generae heat. Charmain has a book on the subject she sells at dirtcheapbooks but there are resources on the net if you do the research. Good luck and keep us informed on your progress.

Hi Anthony,

Basically… the principle involved … is to extract the heat from the wood, store it in a thermal mass then transport to where needed.

The most practical way to do this, that I've heard, is water.  A double wall or water jacketed fire box and an insulated water tank for storage, insulated with lots of papercrete of course. You will probably want a good pump for circulation and a safety valve in case the pump fails.  The idea is to get the fire as hot as possible for complete combustion.  The purpose of a tall stack is primarily for good draw.  Unfortunately this wastes a lot of heat.  You can design with a forced draft that eliminates the need for a hot stack thus allowing increased heat recovery.

Hope this helps a little

 I have watched the post for a while now but really haven't posted. Now
I have a question. I know that this group has a varied group of
opinions. Outdoor woodburning boilers. I did a search this morning
hoping to get plans to make my own. Moneys tight and Michigan is
cold. I have not found plans but I have found lots of flaming by govt
organizations. I hate to be the doubting thomas but I can't help but
to believe that some if not all this flaming is indirectly from the
existing fuel industry. But it has raised several questions for me I
am hoping to get answered. Can these be built more effecient it seems
that oxygen starvation is how these units work(leading to smoke)? I
have read a longer chimney is better anybody have an idea on how tall?
Does anyone have plans or know where I can find them? I am genuinly
curious as to everyones opinion, I personnally live in the country, I
have enough deadfall around my house to heat for years, and thanks to
Michigan icestorms always ad to my supply.
