Emergency heater that don't use electricity | Truck camper testing

I build the candle heat type once, and the terracotta can gets really hot i measured 120 degrees celsius. But as you can see on google a candle delivers heat at around 30 watts. So 3 candles give you not 100 watts. Thats not mutch.

Yeah it was still fun to try. The Canned heat did well.

Liking the real-world testing environment, as well as taking temp readings of the air which is what you feel 👍 I'm not sure what UCO uses for their candles; they do have some different ones. Ordinary wax candles emit about 78 BTU per wick which is also what the average adult human body at rest emits. That's not a lot but a few of them may be enough to survive freezing temperatures if you're nt losing that heat too rapidly. The gelled alcohol (aka "Sterno") will get the can quite hot once most of it has been used, and like the clay pot they can burn you easily so gotta be very careful with both of those. Clay pot adherents point out that those give off radiant heat (true) versus the more convective heat from an exposed flame, but in the end you can't get out more than you put in and that's ~78 BTU's per wick no matter how you use it. On the other side of your enclosure you won't feel the difference, only the air temperature which will be the same either way. The thermal mass of the pot will release it's latent heat slowly after the flame burns out, and it's a good way to keep the darkness which can help with sleeping.

Appreciate the support. I've been looking into the science of it it's really interesting. Figured I'd test a few out
