After heating up spaghetti and ravioli with a single candle flame, two different types of oil lamps and a shortening lamp I decided to try cooking on a three wick candle. I bought a bunch of these candles on clearance at Walmart. This one looks to me like it was made for emergency cooking. Look how nicely that thing from my gas stove fits on top of the candle. So in an emergency situation I will need to:
Get one of the candles.
Get the matches and the stove thing.
Light the candle.
Assemble the stove: (put thing on candle).
Get pan, lid, spoon and soup and start cooking.
That should take about two minutes.
Step 1: Cooking
For tonight’s instructable I decided to venture away from the usual chicken noodle soup and selected a savory Italian Style Meatball soup instead (Progresso18.5 oz.)
The soup took about 15 minutes to be hot enough to be warmed up soup since there was a slight bit of steam.
After 30 minutes there was a slight bubbling / sizzle sound and there was a lot of steam. The soup was officially hot and ready to eat.
There was some actual bubbling after 40 minutes. The soup was at “blow on it” hot.
More bubbles at 45 minutes. The soup was at “better let it cool before you eat it”.
Step 2: Soup's Ready
This will work well for canned foods like soup, spaghetti, ravioli, chili con carne, vegetables and other things like hot coffee, tea and cocoa.
This will probably not work for foods that need to be fried. For that you will need a small propane stove. If you have a propane stove, cooking with a candle will make your propane last longer because you can save it for foods that really need it.
When you need to bring water to a rapid boil (making water safe to drink), my past testing indicates that you can save about 40 percent of the propane you would normally use by using candles to pre-heat the water first. I need to find two spare stove things so I can put one in each car along with a candle (“bug out “stuff).
Another good thing about cooking with candles is that they are safe to use indoors.
Here are a few other thing you can do with this setup: If your emergency situation includes a severe snow storm you can melt snow for drinking water or better yet, coffee. You can also heat up water to put in hot water bottles. It would be nice to be able to wash your hands with warm water.
Step 3: Boiling Water (added 3-3-13)
You can use this setup to boil water. It took a little less than an hour to start boiling. Your results may vary depending on:
Ambient temperature and the temperature of the water.
The size of the flames and how close the flames are to the pan.
The size of the pan.
The amount of water.
I boiled 16 ounces of water four times.
Step 4: Pan Insulation
I tried adding a layer of radiant barrier material (left over from another project) to the outside of the pan. The time it took to start boiling was about the same as the fastest time without insulation but the boiling was more intense.
Here is where I got the radiant barrier material:
Step 5: New Wicks
At some point in time you may need to add or replace a wick. I was able to easily do this with left over birthday candles. I crunched up the candle and added the wax to the 3 wick candle to keep the level of wax up. I pushed a small nail into a new candle to demonstrate how to add a wick. Next I pulled out the nail with pliers and threaded the new wick in the hole and lit the new wick.
The need to add wax to keep the flames close to the bottom of the pan is the one draw back to this setup. You can still heat up soup even if the flames are not right under the pan, just expect longer cooking times. Adding wax from another candle and replacing wicks will keep you cooking as long as you need to.
Step 6: Another 3 Candle Setup
I also bought several of these candles that were on clearance. These are much larger than the other ones. There is no glass container to support the pan which is a good thing because the candle can be moved up and down independently of the pan. I made a holder for the pan using 3 hangers and some tie wraps. I adjusted the height of the candle using a can of tuna, a plate (to catch any wax that may drip), and a few 3.5” floppy discs. I could also use more plates. If I need to raise the candle after cooking a few meals I can add a plate to the stack.
I could also support the pan and stove thing on some bricks.
Step 7: Run Time
I burned this candle for another hour and determined that it burned 0.0225 pounds of wax (about 10 grams). Based on the weight of the candle there should be more than enough wax to boil 16 ounces of water 127 times. The only problem with this candle is that the wax near the sides does not burn. This wax needs to be removed with a knife or razor blade and added to the liquid wax when the candle is burning or saved to be melted and made in to another candle.
The last picture is emergency cooking at the office.
As always use caution with fire. I would suggest not leaving open flames unattended.

Step 8: Using Candles for Survival Heat
You will probably not freeze to death if a blizzard takes out the power in your area this winter but with all the buzz about possible EMP (electromagnetic pulse) attacks and massive solar flares the issue of weeks or months without power during winter needs to be addressed. What can you do with a single candle flame, or better yet 3 or 4? You may have noticed that the room did not become noticeably warmer at Uncle Joe’s 80th birthday party when all the candles were lit. This is because almost all of the heat went straight up to the ceiling and almost none of it radiated out sideways. Also, heating up a room or smaller area takes some time.
Two realistic situations come to mind where building a fire in a fireplace is not an option. These would be: Stuck at work in a blizzard or in an apartment. Let’s take a look at a grocery list of things you can do in an apartment during a long term loss of utilities in sub-freezing weather. This will include among other things, using candles to heat food, keep warm, and melt snow for water.
If you have determined that this emergency situation is going to persist for an extended period of time, you may want to considering doing the following right away. If the water is running, fill as many sealable /closeable containers as practically possible. You need to insure that you have plenty of drinking water. Pick a room or rooms in your apartment where you will be spending most of your time. Get whatever you need out of the rooms you will not be using as often and keep the doors to those rooms shut. You and everyone else will probably spend almost of your time in the living room. If possible fasten a blanket to the top of the “doorway” between the living room and the dining room / kitchen area. This will help trap body and candle heat in the living room. Next it is helpful to create a room with in the room if possible. Ideally a large family size tent, but if you don’t have one, use tarps or spare blankets if you have any to spare. Some nylon rope will be helpful. The idea is to make a fort in the living room like you may have done when you were a kid. It should ideally encompass at least one mattress as well as a table and chairs. The tent will further trap and condense the available heat and it will be great fun for any small children because you can play “camping” (you know, sing songs, tell stories, play crazy eights, etc.). Next move all the stored water (except the water you filled the bath tub with) into the living room. Liquid water has quite a lot of stored energy that it will gladly give up when making the transition from liquid to ice. Large containers of water are like batteries to store heat energy. They will store it when the temperature goes up and give it back when the temperature goes down.
Finally, at long last. Candles. There a lot of unsafe ways to cook indoors. Cooking with candles is relatively safe. Open flames always have the potential for danger. I have several fire extinguishers. You may want to consider buying at least one today if you don’t have one. Next you will want to locate your one or more candle flames under the table. To make sure the candle does not get kicked over surround the candle with 8 one gallon jugs of water in a square pattern. Next place a wire rack from the oven on top of the jugs. The candle will need to be elevated so that the top of the flame or flames are about a half inch below the rack. A few small books should work. Next place a pot or pan of water over the fire. Even if you are not cooking food you will always want to have a pot of water heating. Besides the obvious (warm water to make coffee with) the pot of water efficiently collects the heat energy from the candle flame and spreads it out over a much larger surface area. You will also want a large pot of water heating to add a cup of snow to dozens of times a day to melt snow for drinking water if the need arises. Ideally snow should be brought in once a day at the peak of outdoor temperature and all but one of them initially stored in one of the unused rooms. Food grade 5 gallon buckets are ideal. 5 gallons of snow = about 1/2 gallon of water.
In regard to heating, a candle flame produces about 80 watts of heat. Three flames (240 watts) and a pot of hot water should keep you nice and warm sitting at the table. A table cloth will be helpful to slow the heat’s trip to the ceiling giving you more time to soak it up. The ratio of water to flames determines the type and quality of heat produced. If you want bubbles and steam then use less water. Keep in mind that steam may produce condensation in cold weather. To avoid damp clothing over an extended period of time, enough water should be used to avoid producing steam. a lid on the pan will also help. You may want to put the cooking / heating setup on the table but this will greatly reduce its ability to heat you and the air in your “tent”. You will not be able to utilize much of the light from the candles if they are under the table but that’s ok. Candles are great at producing heat but very inefficient at producing light. May I suggest this flashlight modification? The flashlight costs $5 and the simple modification will allow it to run over 700 hours with an alkaline lantern battery or over 300 hours with the junky battery included:
A few more ideas:
You will need some candles to make this work. Preferably candles with 3 wicks or more. Do you have candles?
Since this is an emergency we are talking about, it may be preferable to have one adult awake at all times to at least be listening to the surroundings and the radio. So whoever is sleeping may want to put one or two 2 liter bottles of warm water in their sleeping bag or in their coat.
A large insulated water cooler with a spigot would be ideal to store warm water if you produce warm water faster than you are consuming it.
Have you ever seen one of those 12 volt water heater units that plugs into a cigarette lighter jack in a car? They are used to heat water or coffee in a cup. They typically produce about 100 watts. Any 12 volt solar panel up to 100 watts can be used to produce some heat.
I bought mine on ebay. Higher wattage water heaters up to 600 watts that are used with wind and solar setups are available here:
