There are many homemade varieties of alcohol stoves as well as commercial stoves available. Alcohol stoves are usually small and frequently used by backpackers. Alcohol (in its pure forms) may be used indoors (with proper ventilation) because it burns so clean. However, some forms may be toxic and need ventilation. We prefer to use denatured alcohol or Everclear for burning indoors.

Any flame can produce carbon monoxide. When pure alcohol burns perfectly, it produces carbon dioxide and water. Although alcohol is one of the safest fuels to burn indoors, proper ventilation is required to ensure enough oxygen for complete combustion. Equip your home with working carbon monoxide detectors! Alcohol is a great storage fuel and has an indefinite shelf life if stored in a tightly sealed container. Two ounces of alcohol will burn in an alcohol burner for approximately 10-15 minutes depending on the stove and type of alcohol.·It has a low flash point, which means that it catches on fire very quickly. Alcohol burns about half as hot as some other fuels, but is a great choice for indoor use.

Alcohol Burner

An alcohol burner is a sturdy, reusable tool for burning alcohol. The alcohol is poured into the center reservoir and lit. It may take a few tries to light as it is the alcohol fumes that burn. Extinguish by gently replacing the cap over the flames and smothering them. Use caution as the flame may be clear or nearly invisible. Do not blow on flames to extinguish. Smother them with the cap and allow to cool completely before tightening.

Military Surplus Alcohol Stove 

This alcohol stove is used for camping, backpacking, and military. The alcohol burner sits in the base. The pots are placed over the base to cook. Alcohol burns half as hot as other fuels. It is extremely flammable, but not explosive. Alcohol will evaporate quickly if left open and lose potency. Keep lid closed tightly during storage.

Canned Heat – Alcohol in a Disposable Can

Sterno is a popular brand of canned heat and works well. Our favorite is Safe Heat because it burns for 6 hours and is relatively inexpensive. It can be purchased at Sam’s Club in the catering section for around $15 for 12 cans. We use a Sterno Single Burner Folding Stove for safety and convenience when using canned heat. The Sterno brand stove tends to be a little more sturdy. It might cost a few extra dollars but is worth it in the long run.

The stoves work well, however, we are concerned about the safety of using them indoors. They produce a large open flame. We recommend that they be used outdoors only. There are much safer alcohol stoves and heaters for indoor use. In our experiment with these burners we tried 3 different forms of alcohol. Notice how much better the 91 percent isopropyl alcohol burned than the 70 percent. The 91 percent is a much better fuel. The denatured alcohol has a very hot almost invisible flame because it burns so cleanly. Great caution must be exercised to avoid accidental fires and burns due to this invisible flame.
