Ooops. I had posted about making it long ago.
We just got a new digital camera and I got to playing with the camera, alas our house right now is a mess, which shows up double in the pictures
Anyway we have a local sponge-cake factory [LaBrees] and they are a continuous supply of 55-gallon drums. They buy lard and pineapple filling in big oil drums. So I get them for free.
The kits to assemble two drums into a stove can be bought from 'Northern' [but other folks have them as well].

$40 is a kit that makes a one barrel stove, another $30 gets you the stacking hardware to make it into a two-barrel stove.
These stoves are rated at 200,000btu.
I lined the bottom barrel with one inch of refractory cement [fire clay] in the hopes that it will never burn out. [okay fine, I do have a row of spare barrels outside so even if it does burn out in five years, I do have ready replacements]
The upper barrel has two preheated air intakes of my own design. Two pieces of black-pipe two and a half foot long, mounted on the front and suspended inside, with caps on the outside. When the stove is hot and drafting good, removing the caps will introduce preheated fresh air into the upper barrel making it into a secondary combustion chamber. I have gotten the secondary combustion chamber glowing orange. This year I have included a temperature gauge so I can see how hot it gets.
Directly above the stove we have an industrial ceiling fan, blowing right down on it. This works well to move air a lot, and to push the heat down and out across the room. We are in a 40' X 60' [2400sq ft] structure, with one room. So the ceiling fans are capable of keeping the heated air stirred up and distributed through-out.
We have under-floor radiant heat. PEX tubing underneath the floors and on the living room seating keeps the floors and the living-room couches warm.
Also between our swimming pool and our jacuzzi is a large heated towel rack, that this hot water also flows through.
So our wet towels are quickly dried, and they are always warm and ready for our use. The towel rack is also large enough that all of our wet clothing and coats can fit on it to dry.
We have a propane water heater and an electric water-heater. Both set at incremental levels so they only kick in when all else should fail.
From the big stove the hot water flows into a thermal bank of 300 gallons. It consists of six 55-gallon drums [did I mention that I have a ready supply of free drums?]
Hot water from the stove is circulated through the thermal bank. Hot water is also circulated from the thermal bank, through the propane and electric water-heaters, through the circ pumps, through the towel rack, through the floor loop, then finally returning to the thermal bank.
Both circ pumps are the cheap Toro 120VAC units. Fed from an inverter, connected to a marine deep-cycle battery, on a charger. If we loose power we should still have heat flow for four days.
We did play with the 12VDC circ pumps, but they were very expensive, and they did not last through the entire season.
Our stove, has two very heavy iron grates in it. Which I bought from:
http://www.woodmanspartsplus.com/
Our local hardware stove, allows me to buy the parts from them, they call the order in to woodmans, and I do not pay for shipping.
We burn green wood, cardboard, paper, peat, and coal.
I have found that it would appear [to my non-chemist eye] that since the smoke stack is straight anything that condenses in the pipe appears to fall down into the secondary combustion chamber. Where it is burnt yet again. This summer when I dis-assembled the entire system for cleaning [yes, I am retired military, I disassemble things for planned maintenance] It was surprisingly clean, I found very little creosote build-up.
We harvest local wood from my woodlot [I own 40 acres of woodlot and I manage another 105 acres of woodlot]. We harvest peat from one of the many local peat bogs. I even have sphagnum moss growing here on my land, so as I cultivate it, in six years I hope to begin harvesting peat from our own bog.
Our grates are flat, not conical. So they are truly not the proper shape for burning coal. I can get a nice coal bed going, but it is just as likely to go out, since the grate is not the proper shape. However it appears that by mixing wood, peat, and coal, it does all get burnt. It provides a lot of heat. I tend it hourly through the evening, and in the morning a little stir and some fresh wood, and it roars back to life.
(Where's a 'green with envy' smilie when you need one?)
