Title: My Rocket Stove
Post by: cameron on January 11, 2022, 09:47:57 AM
Ernie has been talking about rocket stoves lately. This is the one I've designed and have been using for 7 years.

Designed in blender

Made from 1/4" steel. Weighs about 500 lbs.


Lined with firebrick and a custom heat riser so fire never touches the steel. Have had to replace bricks & risers over the years, but zero damage to the steel.

I've been able to heat my ~1500sq.ft home on about 2.5 cords of wood per year/season. I haven't used a traditional wood stove for comparison, but would guess the rocket stove uses 1/2 the wood of a traditional stove.

I also reduced my propane cost by ~70%

Here are the build plans (https://precariat.us.to/GetFile/mZXFi) I gave to the fabricator.

Got a lot of ideas from this guy (Youtube (https://www.youtube.com/playlist?list=PLt8pPbBqBmRgCT8hPGMqnoDpBPVR9R6Vj)). He has a lot of videos building and upgrading his stove.

What would I change?

The tolerances were a little too small for the bricks. So when replacing the bricks, I have to trim them to fit.
I didn't add a secondary air intake to deliver clean, preheated air to the base of the heat riser. This is supposed to increase performance/efficiency.
