Materials Needed For My Design

Approximately 50 red bricks
2 strong and durable food grates (mine were from an old grill)

I built my rocket stove with less than 50 old red bricks. I did not use the concrete mix to put them together since I wanted to be able to tear them down and move my rocket stove if I needed to. With my design, I am able to easily move my rocket stove around on my property as I need, but I have to tear it down brick by brick first!

My rocket stove design is cheap and easy. This is a fantastic build of an off-grid rocket stove for survival that you will absolutely love!

The brick wall in this photo is from my firepit. I built my rocket stove right next to my firepit.

Building the Rocket Stove

To start, you need to set up the foundation of the rocket stove. Place six bricks over the concrete area as shown in this photo. Mine was placed on my backyard patio.

Next, lay down four more bricks as shown in this photo, and place a food grate about the size of the foundation. My food grate fits perfectly, except that it hangs over just a tiny bit in the front, which is okay.

Then place five more bricks as shown in this photo over the food grate. Leaving a food grate in the fuel chamber helps feed the rocket stove more efficiently as I found the wood burns better with some airflow. I also found that the position of the bottom food grate is best one brick layer high for the best airflow and heat output.

Experimenting with Different Heights for the Food Grate Placement

I have tested different levels of height for the bottom food grate fuel chamber for the best result. Having the food grate just one brick high creates the best fire and heat for this rocket stove. Trust me on this, I do not want you to keep tearing yours down over and over trying to find the best placement for the bottom food grate to get a great roaring fire!

Continue stacking the bricks for the next level as shown in the photo. You will now be starting to build the chimney.

Building the Chimney

You can build your chimney as high as you want or need it. Mine is only six layers high. I wanted to be able to cook with my rocket stove, therefore I wanted my food as close to the fire as possible.

Once you have built up the chimney of the rocket stove, you can place another food grate over the top. This will allow you to place food, pots, and pans right over the chimney to cook food and boil water.

Here is a peek down the chimney.

This is a picture of my rocket stove lit up and ready for use! This rocket stove is great for cooking some baked potatoes smothered in butter and wrapped in foil.

The food grates I used for my rocket stove were from an old grill. They are strong and durable enough to use heavy cast iron pots and pans. You can also buy steel food grates to use for your rocket stove.

The soft buttery baked potatoes were delicious and perfect to cozy up next to the warmth of this rocket stove!
