Make a Sand Battery Air Heater at home! no-electricity needed! strong air heater! - w/fan! 300F/150C

DIY Sand Battery Air Heater! no electricity needed! (no power supply is needed for the fan). the whole thing (including the fan) is powered by 6 tealight candles. How It Works: the copper grabs the heat from the candle flames and sends it down into the sand. the sand heats up quickly and begins radiating heat. the fan is then placed onto the copper stand in the center section and the unit cracks out heat for hours. works amazingly well. temps range from 220F-300F(105C-150C). great for all types of situations. only 6 things needed to make it... a big stainless steel cooking pot, a few copper strips, some sand and 6 tealight candles (along with 2 flat stone bricks and the optional 'heat powered' fan. fan is optional but it helps a lot. (sold on amazon). btw, tealights are super cheap at walmart (50 for $3.00)

bonus: I've put a 'glass candle' version of this unit and some 'aluminum strip' experiments near end of the video. using aluminum may be an option but I've just started experimenting with it.

S.C. here...Your videos helped me make food and coffee during Helene. I had just enough battery to find your vids. Please keep making them. My family didnt have these tools, but they came over. Thank you❤

There's many people in western NC who sure could use these right now.

Interesting. This could easily prevent someone from Freezing to death in a bad situation. 👍

Damn dude you are a legend, I’ve been back so many times over the years and you’re still progressing with the sand battery stuff hell yeah man I learned so much about heat conduction from your stuff

Reminds me my grandmother had a xmas do dad with a skinnier candle underneath, and floating angels on top, with strips of metal hanging from the angels. The heat from the candle will make it go around like merry go round and the strips would hit little bells on base. Tinkling. Same principle! Thanks for the memory!!!

I've found that some tea candles give off a lot of heat, and others give off virtually none. Discovered this using the clay flower pot heater.

Make sure you have hot candles before you stock up!

I have an old waterbsth canner full of sand on my woodstove and it will still be giving off head 4_5 hours after the actual fire goes out.

I always look forward to your latest innovations.
Great job as always !
Thanks for sharing.

Love your clever ideas and helps!!!😎👍🙏💯💯💯💯

That's another amazing idea. Thank you and Thumbs-up ~John

Thank you for this heater. I will make one.

I was thinking of filling a pot like that and setting it on my wood burner in my work shop. Do you think the stove would heat up the sand to much? Or would this set up be better?

[stevew]

Very informative and interesting, as always. Thanx.

[Talvish]

Nice, Can this keep a small or large room warm?

[adamkhan]

Do you think this will work as good with table salt?

Also what did you use to cut the metal into strips?

[BillGreenAZ]

Have you tried this rubbing alcohol? I wonder how that would work.

[farleysmith]

I love this, for my non heated craft room. Been using a ceramic heater as my heat source. Looking forward to making this. Question what type of sand are you using?

[lorenbush]

It's hard to believe you can keep coming up with new variations of things.

[deepghetto]

Try a circular pattern that surrounds a center support for the fan. Tea lights on the perimeter (6-8?) and one larger glass candle in the center. One upside down "U" strip over each tea light.

Definitely got to have the candles not too close to the copper or they will soot up and cause the room to smell a bit. Can't get the same temp as you, still experimenting with the set up...
