I am installing a Dickensen solid fuel heater now. this is a good start for heating my little boat under 'third world conditions' whether home or abroad ;^) . I have been thinking about a J tube fed RocketStove cooker/heater for when this one burns out - as any sheet metal stove will eventually.

It sounds like your concept is a good one, with "J" feed for stability, even the burning fuel will not be 'pouring' from side to side as can happen in a larger , traditional fire box in cranky seas. It would be easy to feed and frankly made to use smaller fuel efficiently. Naturally there is the trade off, of a rapidly heating stove for the small fuel, as vice a stove made with ceramic or brick for the heated mass to keep you warm between firings. The Russians had a stove sometimes called the 'Siberian Stove' and other names, that used a relatively quick burn in a massive brick/ceramic stove that had internal fins to absorb as much heat as possible from the relatively short burn and then re-radiate is as stored heat. This also would damp the HOT/cold cycle of a low mass stove.

So - cool idea and I'd love to see more about this. As far as scaling is concerned, the basic coffee can sized stoves would be a good size on my little boat and if you had the down draft heat drum before the updraft flue/chimney you would have a cooking and heating surface - I would think. The recommended size of the chimney for my little Dickensen is 3" and frankly insulating the stack would loose some heat, but ensure a better 'draw' which would be essential for your open "J" in unfriendly winds.

I just bought Dickensen 'barometric flue' which is supposed to help the chimney draw considerably. I'll post my thoughts and observations after this is all installed (likely a few weeks).

Please keep us posted. I'm convinced that high efficiency, solid-fuel heating using scrap is a wise investment in our futures.
