Add more wicks to increase heat.
Step into the world of emergency preparedness with my latest tutorial: the DIY Copper & Sand Heater. This comprehensive guide teaches you how to create a reliable heating source without relying on electricity. Using straightforward materials like copper and sand, you'll craft a heater perfect for unexpected power outages or survival situations. Don't get caught in the cold-equip yourself with this essential heating hack and ensure warmth, safety, and peace of mind. This build comes with a bonus use; have it inside a greenhouse to keep your precious plants from freezing in the cold winter.

This could be used in my tent. I always use a 6 person tent in the winter camp outs....I will definitely try the one with the sand. Thanks a lot!!!
❓❓❓ I have been wondering how many candles can you have lit in a tent and be safe breathing?
I sleep in a winter tent, I made these candles and bought the flower pots,,,,,
But I don’t know if it’s safe to have a candle burning in my tent because of carbon dioxide.
get a carbon monoxide detector.. theyre cheap@@LJ-zk9iw
I'd avoid candles in tents. Too much risk and for next to nothing you can get a 🔦 + a blanket.
Add a Terracotta pot over-top sitting on the sand. This would catch more of the excess heat, share heat with the thermal mass of the sand, and provide more radiating surface area. They were sitting next to each other the whole time, now make them kiss!
Wow, I didn’t even think about that 😃
Smart
You need a black dot which stops reflection of infra red temp beam... Reflection, deflection...off the shining metal surface. Yes .... One dot each side just above sand level on copper plate... And similar dots as you move up arc of copper to the top....
This will offer true readings....
Good video... Very informative... Thanks.

I like the idea of these. Probably better if you got two bands of copper to heat the sand evenly.
That’s a great idea
😃
I was thinking the same thing!
To prevent your wick from tunneling,you need to keep the wick trimmed short; that will also prevent your flame from smoking
It can still tunnel even if the wick is short. Making candles is pure science -- everything is combustible, interacts with one another, etc. It's not as easy as people assume. I also assume you make your own and have found a great combination of wick widths and fuel source, and container physics. Maybe you stumbled upon it by accident, even. If so, share with the class, please!
@@jessicaf6358yeah it's called trimming the wick short
To get much-much more heat -- try using 3 candled inside of 1 glass jar. Thanks for the content)
I like your idea of using the copper strips to heat up the sand and bucket in your heater. Buy if you bend copper tubing the internal heated air might do a better job in maintaining the heat inside the tubing. Thanks for the idea.
Thank you for your work
You might want to use a thermocouples to avoid the errors via your IR sensor
Why didn't you use two copper stripes to have the best heat transfer to all sides of the bucket?
how big of a room will this heat
How warm does this get
if you paint a small section black or something similar you can use your temp gun on shiny/reflective objects. At work we use small black dots we made from adhesive stickers, but this may be too hot for that.
The other day my heating went off and I had to wait until Monday to get it fixed. The night temp was about 3...4 degrees. It was not freezing but it was cold. I got a cake tin with 12 cup cake indents. I used 8 .... eight hour burn time tea lights. I put one on each hold
I got two metal cutlery holders. I inverted both of them ... each covering two candles. I lit them at midnight. They went out at eight in the morning. My bedroom is 16feet square. Average bedroom. I went to the loo during the night and the hall etc was cold. My bedroom was nice and warm. I'm not kidding. I was comfy all night and I hat the cold. I was not cold. The bedroom.temp was about 18 degrees. Comfortable. In fact I keep my heating on 24 hours s day. Now I turn it off when I go to bed and light my candles. I cant wait to get my bill's and see how much I have saved. I put the heating on before I get up. When I go put I turn it off. I tried some normal camels last night. Burn time about 7 hours. The flame is bigger and they throw out quite a bit of heat. I'm go to makea Crisco candle but I'm not stuffing into a bucket. Copper strip is a waste of space. Use an empty been can .. bunch hole in it and put it over the candle.....above the candle so the flame is going into it. Then feel the heat. Touch the can and you will be burnt. I know. Seeya.😅😅😅
It might be a thought to cut some straight copper strips wi black dots and push these straight pieces down into the sand ... Around the unit to offer heat read outs from surrounding areas radiating out from central core.... Just a thought...nice video.

This might also be useful for people with a petroleum or kerosine heater. The bucket with sand can be put on top of the heater which already burns petroleum. Add a heat fan and your heater becomes more efficient.
Could the transfer of heat to sand be causing strip to register at lower temperature.
Is that correct, 72 days of burn at 8 hrs per day?
Cheers for the video. It's interesting to see how many people have different ideas on the candle principle.
Use a fan with a thermal chip to circulate the heat.
How do you circulate the heat
Love that backround picture
Heat rises. You can heat up a copper pipe with it in a vertical orientation, and the bottom of said pipe won't change in temperature. If you invert that pipe, the heat will rise right up the pipe to the top again. When you heat up the that copper band in your experiment, all the heat stays at the top. It's not going to go "down" into the sand.
@@stephenfarrell1556 yes. But this is not heated air, this is conduction by the copper strip, it would travel back down via the strip
@@don_wynn Another way of improving heat use aluminium tape leave a 8x8 inch window then wrap in exhaust wrap again leaving an 8x8 inch window then wrap in aluminium tape.... all so the heat is concentrated on that window
Try turning off the light in the room that is reflecting off the copper, than try the heat meter again.
Try adding 1 gallon of 91 octane gasoline to the sand. The heat from the explosion should create enough radiant heat to heat up the entire house within 5 seconds of ignition.
So the temperature in your garage dropped, got it. 🤦♂️
Bad non contact thermometer. Try a different one.
Flame is too far from the copper. Needs to be touching.
The temp 6 inches from the bucket is pointless. If this is such a great device to heat a SMALL ROOM or greenhouse....... you let it run and use a room thermometer and take readings from it every 15 minutes. Sitting 6 inches from the bucket to get warm is plain stupid. 😮😮😮
72days for jow long each day
he say 8 hours a day not 24 over 24
Or you could get a wood burning stove...
Uhm... im afraid the sand and copper is not doing anything.
The amount of joules the candles give do not change.
Offcourse the sand may get a bit warm because of the copper, but that will be gone before you can say cheesecake😂😂
Gives the radiation effect better rather than heat just being lost in the air n pulled up too the ceiling the sand will help hold n distribute the heat into your space around you its like a bare fire place with all the heat going up the chimney vs a Woodburner which is far more heat efficient and the copper helps transfer heat into the sand faster
@@jshaw4757okay but then why tf not just have the sand ABOVE the candle. There is so much heat loss with this setup it's insane lol
In theory, it sounds good, but when the candle burns down lower in the jar, will the flame not be too low to reach the copper?
the clay pot/copper strip provide no benefit. the candle provides a set amount of heat, adding items does not create more.
They certainly provide benefits. It isn't about producing more heat. It's about directing the heat and storing its energy in the sand. The copper strip heats up and then heats up the sand.
@@educational4434 If you understand how heat works, you'd understand that it tends to travel UPWARDS. If you're trying to harness the heat, why on earth would you put the sand below the flame lol. The losses in this setup are insane
No way 72 day burn time.
I have tested it
😃
do a real believable time lapse video please . or your lying@@don_wynn
It’s gotta be 72hrs
@@don_wynn Are you saying a tub of Crisco last 72 days for 24 hours a day each day?
No way do I believe that those candles burn for 72 days. Are you burning them for 24 hours each day? But the you said the burn time is 6 days, yet the video description still shows 72 days. The it's "Vid-E-O", not "Vee-D-O".
Don’t waste your money your time to do this.
