Default DIY Rocket stove - simple and runs on twigs!

Interesting and simple brick stove. This would make for a great back yard setup IMO.

I hope to have something very similar to this, by the time I need to cold pack the garden vegetables.
It would have been great the last two weekends when I brew some Ale. Bringing a mash tun up to 150F and boiling the 13 gallon of wort for an hour, sucks up some natural gas. I'll need to add some type of diverter, so I can adjust the heat going to what I'm cooking. Any ideas on help controlling the heat?

I'd think some sort of air vent with a valve to allow the heat to bypass the cooking surface would work nicely.

A friend of mine has been making these for a few years no, his latest is a portable one about the size of a large boot that is made out of refractory cement and sawdust, cast in a cardboard form.

8 inch over 6 inch. notched it so the 8 inch would touch bottom of barrel.






Used a mix of Perlite and clay cat litter to insulate the riser. Used broken brick and some volcanic rock to hold things in place and heat sink.










Need to make the riser little taller.

Neat!! Here's the cute little portable model for those don't want to DIY..
Grover Rocket Stove - Preparedness Saves The Day





If one was handy with metal, he could make and sell these things on Ebay..

And, if the economy keeps going the way it's going now, these things
could be worth their weight in $100 bills, before long..

Coiled 120 foot of half inch copper around the outside of the riser. I should have found someway to fasten the coil of copper to the lid for better heat exposer. Placed fire brick around the fire chamber, don't think the metal will hold up. Added a chimney to draw the heat down over the copper.

Was able two raise 450 gallon of water 2 degrees with a five gallon bucket full of paper and wood.

Going to go ahead and Permanent mount it in the shed, so I can insulate it and set up the controls and pump. Think I'm going to add a batch tank on top of it.

Doesn't that double chimney, with the air gap slow down the heat transfer to the copper tube?

Seems like you would get hotter water by installing a coil between the two chimneys.

If I was going to make one of these cookers to heat water,
I would be tempted to try putting a coil inside the main chimney wall,
right in the flame.
Maybe just on the top half, so the bottom section could heat up properly,
to create the draft needed for a hot fire.


I wonder how your chimney would work, if you filled the air-gap between
the chimney walls with sand or gravel?
It would take longer to warm up and really start drafting, but the sand
would conduct the heat to the copper coil.?. Maybe?
