TIN CAN Air Heaters! - Survival/SHTF Air Heater/Stove - Simple "cardboard and Wax" Design

in this instructable i'll show you how to make metal can air heater/stove using almost nothing

Homemade DIY Air Heaters. Easy Step-by-Step Instructions. Made with: metal cans, cardboard and candle wax. great for Survival/SHTF situation or everyday use. hi temps. burns a long time. compact and portable. good for use while camping, hiking, fishing, hunting too. the heaters were made entirely from "trash" (scrap cardboard, wax from old candles, and empty soup/vegetable/tuna cans). can be used as a stove

all you need is...

1.) old metal/steel food can (or cans)

2.) scrap pieces of cardboard

3.) candle wax (i used the wax from some old "worn out" candles)

4.) and old saucepan (to melt the wax)

...and only tool needed is a knife or spoon (to dig out the wax from the old candles)

start by taking strips of cardboard and rolling them up (see pics)

place the rolled up cardboard in the can...

if you're candles are the type that are in a glass container, then take a knife or spoon and carefully dig out the wax. i used some old candles that were at the end of their useful life. i put the wax in an empty metal can temporarily (see pics)

put the wax in a saucepan and heat it (over low heat) until it's melted.

with the cardboard in the can, carefully pour the wax over the cardboard. i spilled some as you can see. then light it up.

to put them out, just cover it. (i use the bottom of a metal pan)

note: these put off noticeable smoke so they are best used oudoors. remember to take care when using these and don't leave them unattended when lit. note that the entire project is made with things that would normally be considered trash and just thrown away. it's a great way to reuse/recycle
