Preparedness Challenge: DIY Emergency Survival Heater
Years ago I worked with a group of like minded people to get prepared. We purchased food in bulk, make 72 hour food kits and made these easy DIY Emergency Survival Heaters.
I found mine the other day and decided to give it a light and see if after 10+ years it still works. It does, but I learned it has a major flaw that needs to be fixed. My original heater has a box of matches hot glued to the lid of the paint can. When I lit my heater, the flames really jumped up – 6 to 8 inches and I was planning on using the lid as a damper.
Picture me standing there…lid in hand… mentally debating whether I should place the lid with a box of matches attached to it over this open flame. Obviously, using it as a damper was not an option, I was afraid the flames would curl around and light the box. After a second of thought, I used a plate to extinguish the flames and decided I needed a better way for the future.
If you are without power, this emergency heater will come in handy for cooking or hand warming. Exercise caution with an open flame in your home. You may not need to worry about carbon monoxide poisoning while using rubbing alcohol as a fuel, please be safe and open a window to vent – just to be sure.
This is an adult tool, not for kids!
Just follow these instructions on how to make a DIY emergency survival heater and learn how to use it. The cost is minimal (about $6) and the heat output fantastic. It is reusable and to refuel you only need to purchase 70% rubbing alcohol.
- // The paint can gets REALLY HOT when it’s lit, so make sure you place your emergency survival heater on something fireproof. I used a ceramic hot pad.
- // Have pot holders at the ready in case you need to move it.
- // Have a way to tame the flame. When I lit mine, the flame was 6 to 8 inches high. That might be too much heat for the cooking you plan to do. The paint can top works well for this.
- // Have a way to extinguish the flames (water is NOT the way). You can use the paint can top or a plate to cover the flame.
- // As a precaution, vent your area.
Today’s Challenge – Make a DIY Emergency Survival Heater
1 new quart size paint can
1 bottle of 70% rubbing alcohol
1 roll of toilet paper
1 box of matches
a quarter, large coin, or other prying tool
some packing tape
a hammer or mallet
Remove the cardboard roll from the inside of the toilet paper roll. Then decide if you need to remove some paper from the roll so it will fit. I used a cheap one ply, but I still had to remove some from the outside of the roll. Squeeze it in as best you can. I used the end of a sturdy spoon as a lever.
Place the TP roll into the new paint can, it should completely fill it. Slowly pour in the bottle of 70% rubbing alcohol. It will absorb into the paper which acts as your wick.
Hammer on the lid. Place the quarter inside the match box and attach it to the side of the paint can with the packing tape. Remove the matchbox and packing tape before using your emergency survival heater, remember, the can will get hot.
To Use Your DIY Emergency Survival Heater
Pry off the top of the paint can with your quarter or a screw driver. I actually found out that my fingers are wimpy and I couldn’t get enough leverage with a quarter. Screw drivers are for me!
Prepare your area – have something non-flammable to place it on, have your hot pads ready and a way to extinguish or damper the flame.
Light a match and light the toilet paper roll inside the paint can. This will ignite the rubbing alcohol but will not burn the TP roll. The toilet paper roll is your wick. If it starts to burn, extinguish the flame, let it cool and add more rubbing alcohol.
You can use your survival heater to warm a room or as fuel for cooking. Review our post Emergency Cooking for instructions on making a #10 can cooker and How to Prepare for Blackouts for general preparations.
