Boiling water with a candle may not be the most efficient way to heat water, but it is a valuable skill to have in emergency situations where electricity is unavailable. It is a lightweight, hardy, and multi-purpose tool that can be used for lighting, patching rips, or even boiling water. To boil water with a candle, you will need a candle with multiple wicks, a pot with a thin bottom, a metal burner, additional wicks and candle wax, a fire starter, and an additional fuel source. The candle should be placed on a stable surface, with the metal burner placed on top, and the pot of water placed on top of the burner. The closer the candle flame is to the pot, the faster the water will boil.

What You'll Learn
Candle type: Multi-wick candles burn hotter
Multi-wick candles are designed to burn hotter than single-wick candles. This is because the multiple wicks work together to ensure the candle gets hot enough to create an even melt pool. By having more than one wick, the wax is able to melt more evenly and completely.
When burning a multi-wick candle for the first time, it is important to let it burn for 3-4 hours until the wax has thoroughly and evenly melted to the edge of the glass. This initial burn will prevent tunnelling and extend the life of the candle. Each time you burn the candle, ensure all wicks are lit. Burning a single wick will cause the remaining wicks to ""suffocate", making it harder to achieve an even burn.
To get the most out of your multi-wick candle, be sure to trim the wicks to 1/4 inch before each burn. This will optimise burn time and maximise fragrance diffusion. A large flame indicates that the wick is too long. Do not burn the candle for more than 4 hours at a time and allow it to cool for 24 hours before relighting.
Multi-wick candles, when burned properly, can burn for 50-60 hours.

Pot: Use a thin, narrow pot with a cover
When it comes to choosing the right pot to boil water with a candle, there are a few key considerations to keep in mind. Firstly, it is recommended to use a pot with a relatively thin bottom and a narrow shape. The thinner and narrower the pot, the more efficiently the water will heat up. This is because a smaller surface area allows the heat from the candle to be concentrated on a smaller area, increasing the temperature more quickly.
Additionally, using a pot with a cover is advantageous. The cover helps to trap the heat generated by the candle, increasing the pressure inside the pot. This increased pressure raises the boiling point of the water, making it easier to reach the boiling point. It also reduces heat loss due to convection, further improving the efficiency of the heating process.
When selecting a pot, it is also important to consider the size of your candle setup. The larger the pot in comparison to the candle, the longer it will take for the water to boil. Therefore, choosing a pot that is proportional to your candle setup is crucial for optimizing heating time.
To further enhance the efficiency of the setup, consider using additional wicks and candle wax. By adding more wax and a longer wick to the candle, you can keep the flame closer to the bottom of the pot, minimizing heat dissipation. This simple modification can make a significant difference in the time it takes for the water to reach its boiling point.
In summary, when attempting to boil water with a candle, opt for a thin, narrow pot with a cover to increase efficiency. Additionally, ensure the pot is proportional to your candle setup and consider using additional wicks and wax to maintain a close flame for faster heating. With these considerations in mind, you can effectively utilize a candle as a heat source for boiling water.

Burner: A metal burner is placed between the candle and pot
Boiling water with candles is possible, but it is worth noting that there will be a long boil time. It is also important to be cautious when handling candles and open flames.
A metal burner can be placed between the candle and the pot to boil water. This setup can be used to heat water for drinking, or for hot water bottles. The metal burner will help to direct the heat from the candle towards the pot, improving the efficiency of the setup.
The metal burner should be placed on a stable, heat-resistant surface, such as bricks, to avoid any accidents. Multiple candles can be used to increase the heat output and improve boil times. Tea light candles are a good option for this setup, as they are small and can be easily placed under the burner.
It is important to note that the wax near the sides of the candle may not burn, so it may be necessary to use a knife or razor blade to remove this wax and add it to the liquid wax while the candle is burning. Alternatively, the wax can be saved and reused to make new candles.
The fumes from extinguishing the candles should also be considered, as they can be noxious. It is recommended to let the wax cool down completely before removing the snuffer to avoid releasing a cloud of smoke and fumes.

Fuel source: An additional fuel source increases the energy output
Boiling water with a candle can be a valuable skill in emergency situations where electricity for cooking is unavailable. However, it is not the most efficient method, and the primary challenge is that candles often burn out before the water reaches its boiling point.
To increase the energy output and improve the chances of successfully boiling water, an additional fuel source can be introduced between the candle fire and the pot. This could be something like a bare-metal can filled with shredded tinder and dripped wax as an accelerant. This setup will increase the amount of heat generated by the candle, making it faster and easier to boil water.
When using an additional fuel source, it is important to ensure that the setup remains stable and secure. The candle should be placed on a flat, even surface, and a metal burner or grate should be positioned directly above the candle, as close to the flame as possible. This helps to direct the heat upwards towards the pot and reduces heat dissipation.
Additionally, the type of pot used also plays a role in how effectively the water boils. It is recommended to use a pot with a relatively thin bottom and a narrow shape. A pot with a cover is also advantageous as the increased pressure will raise the water temperature more quickly.
By combining an additional fuel source with the right equipment and setup, you can significantly increase the chances of successfully boiling water with a candle. This knowledge can be especially useful in survival or emergency situations where alternative sources of heat or electricity may not be available.

Firestarter: Use flint, matches, or a lighter to light the candle
To boil water with a candle, you will need a fire-starting tool to light the candle. While flint, matches, or a lighter can be used to light the candle, each has its own advantages and disadvantages. For example, windy conditions will impede lighting matches and candles outdoors. In such a scenario, a lighter would be a more suitable option.
Flint and steel are a traditional method of creating sparks to start a fire. To use flint and steel to light a candle, you will need a piece of flint, a piece of steel with a sharp edge, and a piece of char cloth or other suitable tinder. Hold the flint steady in one hand and strike it with the sharp edge of the steel, directing the sparks onto the char cloth. Once the char cloth begins to glow, use it to light the candle.
Matches are another option for lighting a candle. They are convenient and easy to use, but they can be difficult to light in windy or wet conditions. To light a candle with a match, simply strike the match on a suitable surface, hold it close to the candle wick, and adjust the match until the wick ignites.
A lighter is a portable device that produces a flame and can be used to light a candle. Lighters are typically easy to use and are less susceptible to wind and moisture than matches. To light a candle with a lighter, hold the lighter close to the candle wick and use the flame to ignite the wick.
Having multiple fire-starting tools on hand is ideal, especially in emergency situations. This ensures that you have backup options if one method is not suitable for the current conditions or becomes unusable.
