How To Build a Rocket Stove Oven

Oven 12

Building a rocket stove oven is not just a DIY project, it’s an investment in a sustainable and efficient cooking method. Whether you’re an outdoor cooking enthusiast, a prepper, or someone looking to reduce their carbon footprint, a rocket stove oven can be a game-changer. This in-depth guide will take you through the process of building a rocket stove oven, from understanding its basic principles to gathering materials and following a step-by-step construction guide.


To build a rocket stove oven, start by choosing a design that suits your needs. Gather necessary materials such as firebricks, a steel drum, corrugated steel, perlite and wood ash, stainless steel cylinders, bricks and cob, and sawdust. Follow a step-by-step guide to prepare the base, build the combustion chamber, construct the chimney, and add a cooking surface. Test your rocket stove once it’s complete, and ensure you take safety measures during the building process and regular maintenance afterwards.

What is a Rocket Stove Oven?

A rocket stove oven is an efficient and hot burning stove that uses small-diameter wood fuel. It’s designed with a simple combustion chamber containing an insulated vertical chimney, which ensures almost complete combustion before the flames reach the cooking surface. Rocket stoves are known for their efficiency, using 18 to 35 percent less fuel compared to traditional stoves and reducing fuel consumption by 39 to 47 percent compared to open, three-stone fires.

Materials Needed

To build a rocket stove oven, you’ll need the following materials:

  1. Firebricks
  2. 55-gallon steel drum
  3. Corrugated steel
  4. Perlite and wood ash
  5. Stainless steel cylinders
  6. Bricks and cob
  7. Sawdust

Step-by-Step Guide to Building a Rocket Stove Oven

Step 1: Choose a Design

There are various designs available for rocket stoves, from the 16-brick rocket stove to the #10 can rocket stove. Choose a design that suits your needs and skill level.

Step 2: Gather Materials

Depending on the design you choose, you’ll need different materials. For instance, a 16-brick rocket stove requires bricks, while a #10 can rocket stove needs a large can, smaller cans, and insulation material.

Step 3: Prepare the Base

For a brick rocket stove, arrange bricks in a square or rectangular shape, leaving an opening for the fuel chamber. For a can rocket stove, cut an opening in the side of the #10 can for the fuel chamber and insert a smaller can to create the combustion chamber.

Step 4: Build the Combustion Chamber

Stack bricks to create a vertical combustion chamber for a brick rocket stove. For a can rocket stove, insert a smaller can into the #10 can and fill the space between the cans with insulation material.

Step 5: Construct the Chimney

Continue stacking bricks to create a vertical chimney above the combustion chamber for a brick rocket stove. For a can rocket stove, cut a hole in the #10 can lid and insert a smaller can to create the chimney, then secure the lid to the can.

Step 6: Add a Cooking Surface

Place a metal grate or flat stone on top of the chimney to create a cooking surface for a brick rocket stove. For a can rocket stove, the top of the #10 can serves as the cooking surface.

Step 7: Finishing Touches

Add a handle made from a metal hanger and spray the stove with high heat spray paint for a polished look for a can rocket stove. For a welded rocket stove, grind the top of the chimney and the mouth of the stove to create a smooth, planar surface.

Step 8: Test Your Rocket Stove

Once your rocket stove is complete, test it by lighting a small fire in the combustion chamber and placing a pot or pan on the cooking surface.

Safety Measures

When building and using a rocket stove oven, it’s important to take several safety precautions. Always use appropriate materials, ensure proper ventilation, maintain a safe distance from flammable objects, use dry wood, install heat and smoke detectors, and clean the rocket stove regularly.

Maintenance Procedures

Regular maintenance is crucial for the longevity and efficiency of your rocket stove oven. This includes cleaning the ash and the chimney, checking for cracks or damages, maintaining the oven door, cleaning the oven interior, and preheating the oven before use.

Common Mistakes to Avoid

Building a rocket stove oven is a straightforward process, but there are a few common mistakes to avoid. Ensure you use the right materials, provide enough airflow, use dry wood, pay attention to dimensions, avoid overheating, be cautious with fire, and learn from others’ experiences.

In conclusion, building a rocket stove oven may require some time and effort, but the benefits are well worth it. With this comprehensive guide, you’ll be well on your way to creating a sustainable, efficient, and cost-effective cooking solution. Happy building!

Frequently Asked Questions

What is the purpose of the insulation in a rocket stove oven?

The insulation in a rocket stove oven helps to keep the heat concentrated in the combustion chamber, which improves the efficiency of the stove. It prevents the heat from escaping and ensures that the maximum amount of heat is directed towards cooking.

Can I use any type of wood as fuel for my rocket stove oven?

It’s best to use dry, small-diameter wood for your rocket stove oven. This type of wood burns more efficiently and produces less smoke. Avoid using treated wood as it can release harmful chemicals when burned.

How often should I clean my rocket stove oven?

The frequency of cleaning your rocket stove oven depends on how often you use it. However, it’s a good practice to clean the ash out after each use. The chimney should be cleaned periodically to prevent buildup which can reduce the efficiency of the stove.

Can I use my rocket stove oven indoors?

While it’s technically possible to use a rocket stove oven indoors, it’s not recommended due to the risk of carbon monoxide poisoning. Rocket stoves should always be used in a well-ventilated area, preferably outdoors.

Is it safe to leave my rocket stove oven unattended while it’s in use?

No, it’s not safe to leave any open fire unattended, including a rocket stove oven. Always monitor the stove when it’s in use to prevent accidents.
