Do you need an alternative cooking source that is inexpensive, quick to put up, relatively mobile, and easy to use that is more than a small rocket stove? Today, one of my friends, Bunny Wickham, is guest posting on the blog, sharing her story of how she and her husband built a concrete brick rocket stove in one afternoon.
They now have an alternative, non-permanent means of cooking at their home in the case of an emergency. This is even portable in case they need to relocate.
DIY ROCKET STOVE PLANS – EXPERIMENT
with Bunny Wickham
How Did You Get Started Building a Rocket Stove?
After watching a few tutorials on YouTube, my husband and I decided to give it a whirl based on the rocket stove plans we draw after. We were really, really pleased with the results.
The fact that the tender sits up off the bottom allows for airflow to be drawn in and up the combustion chamber. I was surprised at how little wood I had to add to produce a really hot fire. I just gathered a couple of handfuls of sticks and twigs from the yard, and we were cooking!
The design of a rocket stove lends itself to super-efficient cooking…gotta love that!! Being able to cook and boil water in a grid down situation is critical. Sure, we still have the grill, the fireplace (inside), the firepit (outside), and the solar oven but this just gives us one more option.
How Does a Rocket Stove Work?
The pot/pan has to sit up off the bricks to allow for the air to pull up the chamber. We used some scrap metal that I put on either side of the opening to rest the pot on. I’m going to check at the salvage yard (where people dump old stoves) and see if I can find some burner grates. I got the plans from a Youtube video from Sensible Prepper called DIY Brick Rocket Stove (see below).
The screen at the bottom is where you put the wood, it’s up off of the brick and allows for airflow to draft in and up the combustion chamber, which you really need for this design. The one on top was just used to cut down on potential sparks that might have come out but honestly, you don’t need it. 
What Supplies Did You Need?
- 27 concrete bricks
- Grate
- Metal Screening
What About the Suggested Dangers of Concrete Bricks in a Rocket Stove?
These are just regular concrete bricks. We researched it a bit and determined that it would be suitable for occasional use. I felt the side of the bricks as I used it and the outside part of the brick was barely warm after I’d cooked on it so I think the heat transfer will be okay.
[editor: Your mileage may vary. While Bunny suggested this is good for occasional use, using non-fire bricks may be a danger for exploding if you run them often in extreme heat.]
About Bunny:
- I am a mom of 4, married 25 years.
- I have a background in Emergency Management and a passion for preparedness.
- I am a founding member of our county’s CERT program (Community Emergency Response Team)
- I embrace the homesteading/back to basics movement.
- I am an avid baker, I LOVE the smell of freshly baked bread filling my kitchen! 🙂
- …I have yet to try bread on the rocket stove though. I have seen an oven component to the rocket stove…maybe that should be my next project!?!
From Jane: This is definitely a project you can do with your family in less than two hours. We have a small portable rocket stove that is great for going on the road (and now we love this Solo Stove even more!), but this is one we want to have in our skills pantry to be able to put together in a heartbeat in a localized emergency or just to have fun with camping in the backyard.
It would even be something we’d consider taking with us if we were camping for a weekend. It would just line the bottom of our trunk since it is not a permanent structure, and we could build it wherever we needed it. Be sure to watch the video below to see one in action!
