Are rocket stoves safe?

To answer this question effectively we need to define a rocket stove (or rocket mass heater) first and evaluation the design of each one.

What is a rocket stove?

A rocket stove is an outdoor wood-burning cooking stove. It was developed in the 1980’s by Dr. Larry Winiarski as an effective, safe, and eco-friendly design compared to open fires for poverty-stricken people in developing nations.

Compared to three-stone fires, also known as conventional fires, a portable rocket stove is more efficient and healthier.

The design of rocket stoves also reduces smoke and toxic emissions significantly – which is especially great for camping. Apart from using less fuel wood, they use the energy from wood more efficiently, which is then converted into heat energy.

How’s the rocket heater used in some regions?

In some regions, having readily accessible rocket stoves for sale helps cut down pollution of air. They also facilitate efficient cooking, prevent extensive deforestation, and offer employment opportunities. Internally displaced persons and refugees use the rocket stove heater to prepare meals whenever fuel is unavailable or wet.

A homemade rocket stove is a cost-effective method you can use for camping or survival emergencies. From this explanation, it’s evident that a rocket mass stove is safe and effective.

How long will a rocket stove burn?

A rocket stove DIY burns small amounts of wood and can heat for more than 12 hours.

How do I make a simple rocket stove?

You can make a DIY rocket stove using readily available materials in your home as we shall see below.

Items you’ll need

  • 1 – No. 10 tin cans. This is a standard size can. You can recycle one from your old food packing tins.
  • 4 ordinary soup cans / tin cans
  • Insulating material. You can use ashes, dirt, foam, or sand

Tools you’ll need

  • A nail and hammer. You’ll use these to make starter holes
  • Tin snips
  • Pliers to ease the process of bending your material
  • Gloves to protect your hands, and
  • A file


1. Mark and cut your can

Ready to build one?

Ensure your No.10 can doesn’t have any labels before marking it. Pick one of your ordinary soup or tin cans and trace a circle nearly at the bottom vertical part of your No.10 can. Cut out that part and ensure your small can fits well in the hole you’ve just created on your bigger can.

Cut out one of your ordinary soup tins

Use the small part you just cut out from your No.10 can. Mark and cut out a hole in the same position as you did with your bigger can. Your second soup can should be able to penetrate through the No.10 can first.

Next, they should pass through the first soup can to create an elbow. Remember to fit one of your soup cans through the hole you created in your No.10. This way you’ll ensure it’s neither big nor small.

2. Cut off your second soup can to create a feeding tube

Remove the bottom part of your soup can. You can easily do so using a can opener but tin snips will work well too and are much faster. Remember, the bottom part of your can isn’t similar to its top part. This makes it harder to open using a can opener.

You’ll use your second soup can as the horizontal feeding chamber of your rocket stove water heater. Here, you’ll also need to dry-fit your first two soup cans.

This is to determine whether they’ll fit well inside your No.10 can during the assembling process. Place your first soup can at the center of your No.10 can.

Its hole should be in line with the hole in your No.10 can. The open end of your first soup can, should face up. This will enable you to insert your third soup can inside to play the part of a chimney later on. Your second soup can should penetrate through the No.10 can’s hole.

It should then go through the hole in your first soup can to create an elbow.

3. Cut your third soup can to make a chimney

Remove the top and bottom parts of your third soup can before vertically cutting it open from its top to bottom. You’ll use it as the chimney stack. Place it inside your first soup can (the one sitting inside your No.10 can).

You’ll notice that you may have to cut off nearly a quarter-inch of excess can to make it small enough to fit neatly inside your first soup can. Seasoned jet stove makers recommend making a small arch in the third can where it divides your second can. You want to avoid a scenario where your chimney is too tall when the rocket stove is completed.

Your chimney should be around a quarter inch beneath the top of No.10 can’s rim for suitable use. To get the right size, cut your third soup can down, and leave out its arch. This will work well so long as you have the appropriate chimney height concerning your No.10 can’s rim. Once you’re satisfied, go ahead and fit your chimney.

4. Make a hole on the lid of your No.10 can

Pick your chimney (third soup can). Trace its shape on the lid of your No.10 can. You’ll need to cut it out to allow your chimney to penetrate through the rocket stove’s top. To make this process easier, place the lid on a piece of wood. This will give your nail something to penetrate. If you place your lid against a hard surface, the nail won’t penetrate through as recommended.

Some people prefer placing it (lid) on dirt. The disadvantage of this is that your lid may end up bending. A small piece of timber will work well in this process. Cut the hole off to size before test-fitting your chimney.

5. Bring together your pieces and fill in insulation before sealing the lid

Now you’ve cut out and fitted all the parts of your rocket heater stove. You’ll need to bring together your combustion chamber (first soup can) elbow (soup can 2) and chimney (soup can 3) inside the No.10 can.

Once you’ve assembled, fill in the remaining spaces with an insulator. Like we’ve mentioned before any insulating material will work well. You can use ash, foam insulation, foam, clay, or even sand. You can also buy perlites from a home improvement store near you.

Fill in the area slowly and take time to rattle and tap your can to ensure insulation settles inside any gaps in your combustion chamber.

Avoid adding too much insulation. Doing so could disassemble your jar. Fill insulation in your No.10 can up to around half an inch right below the rim. Now, use your tin snips to make about one-inch vertical incisions in your No.10 can from the top edge.

This will form tabs that you can fold down to hold the lid in place.

When your can is finally insulated, put its lid on top and fold the tabs down. You’ve now assembled your stove and what remains is to cut out a small fuel shelf.

6. Use your fourth soup can to make a fuel shelf

With your fourth soup can you’ll need to create a small shelf that’ll fit well inside your DIY wood burning stove’s mouth. This area is where wood will rest on. Air will also travel in your stove through this opening.

Cut a “T” shape and make sure it’s a similar width to your first can. It should, however, have a wider section at the top area to prevent it from drifting inside your stove. According to DIY enthusiasts who used the fourth can in this process, it can be inadequate.

You may want to cut out a larger can instead to ensure your fuel shelf protrudes further out of the No.10 can.

This will make sure that the weight of wood will stick outside your No.10 can. Eventually, wood will be to rest on it comfortably without knocking your DIY wood burning stove to the ground. Resize your fourth can before putting it in your stove’s mouth.

Make there’s a gap at the bottom and top. Without a gap, your stove won’t work properly.

7. Light up your stove

You’ll only be able to hold your stove safely in your hand while making it. Once you’ve lit it up, the outside becomes too hot and you shouldn’t try to hold it with bare hands. There are various methods of lighting up your stove.

For example, you could shove some old newspapers inside the chimney and light it up with a match or lighter. This method will work well but you need to put in small bits of papers at a time. You could also insert a few pieces of wood down your stove’s chimney at first.
