I built this simple guy out of some stuff I had lying around after I saw the idea online. There are better alternatives, but this works alright. Good for a power outage or stranded in a storm or even to carry in cold conditions.
If you buy everything new it'll prob. cost about 4-6 bucks a heater. They are refillable.
Isopropyl is a good alternative to denatured. It could also be used for bandages, but I have access to large amounts of denatured, so that's what I went with.
Empty cans are <$3 at home depot.
I <3 Palox.
(picture frame holder, cheap, any hardware store, small, works)
can be reclosed leak tight with palm of hand, but use a rubber mallet for best shelf life.
Don't just pry the lid off - you'll bend it and then it won't close right. Work around it.
I think one will go on a shelf in the garage, the other in the trunk.
The directions are good if I want to give them to people. Date them. They should last a long time (at least 3 years, probably more) on a shelf - the cans are coated on the inside (no rust) and are pretty air tight.
Tested in a car with windows just cracked and a carbon monoxide tester: no fumes detected. Heats up fast. Choked down with lid half on top (will get hot) will conserve fuel and limit output.
Once the fuel runs out (~4 hours full flame) the TP will burn, so don't leave it unattended inside a car. Easily extinguished with lid of can, and alcohol fires are easy to snuff out. TP baffle limits spillage but don't knock it over, you'll be unhappy.
I carry a jumpstart battery pack (got used today, not on my car but good to know it works), jumper cables, folding shovel, moving blankets and a basic first aid...
So what else could go into a winter emergency kit? Blankets bandages shovels?
