Flowerpot Air Heater! New Design! w/Copper+Sand! (300F/400F)(150C/205C) home/mini greenhouse etc...

DIY Clay Pot Air Heater! New Design! Now with heat-conducting Copper Strips and Sand for maximum heat absorption and retention. How it works: the heat of the candles is absorbed and directed down into the sand (using the embedded copper strips) where it's stored and released over time. once the sand is heated the unit produces a steady amount of continuous heat. (and for several hours even after the candles go out).

Only 4 items are needed: a clay flowerpot, copper strips, sand and tea-lights (or small glass candles). that's it. and it goes together in a few minutes.

📌 the unit takes about 45 mins to 1 hr to warm the sand 'all the way through' (and will continue warming with each passing hour). top temps seem to be around 300F/150C with one tealight under each copper strip and 400F/205C with 2 candles under each strip.

🔶🟠 A good source for the copper (and where i buy it) is discussed in the video. it's essentially bulk copper (99.9% pure) by the pound (on amazon)

🌱🌱 Just a thought but it's a nice steady heat so it might work well as
an off-grid heater (or supplemental heater) in a small or mini greenhouse.

I've been watching you for around 10 years and this is the best one I can remember for this flower pot type heaters!

Hi. To get candles to last longer, sprinkle salt on them. There are DIY "forever" candle ideas on youtube, using a jar, wick, salt (or water) and cooking oil. Also, you.can light a dry spaghetti noodle and use it as a long matchstick. I too have watched you for years. Thank you for sharing your ideas and helping us to think creatively. We are all in this together.

As a new homeowner of a 70 yr old house with horrible insulation, I'm excited to finally have the opportunity to implement many of your projects. You made me want a solar oven for example so bad!

Super cool and the sand 'may' extinguish the candles if it is somehow knocked over too.

I like the direction of this heater build. My thought would be to set the clay pot on blocks and insert a thin one inch pipe over the drain hole extending upward a few inches out of the sand as a circulator. I cool my garage with one of your evaporative window fan cooler designs and like it. Keep'em coming Friend.

Oh that’s clever … think I’ll make a square u for a platform for a heat propelled fan … this is a terrific idea THANKS FOR SHARING ❤️
Edit😆
Ha just read comments … thinking the plates can be cut and slid together like hands/fingers interlocking to make a continuous squared off oval type platform insert … love all your vids and the ideas from subs …

Thank you for the great info. You can use this principle to build a 21st century masonry heater that use copper bars to transfer hot air from wood fires to surrounding sand enclosed by masonry blocks instead of relying on elaborate air channels.

They make spring-loaded candle holders, would be prime for this. As the candle burns down, a spring in the tube pushes upward.
And thanks for the video!

Very very. Clever design. Awesome dude
Unique
Thank you for this

[HeywoodJabozoff]

as i am building a sand battery with the copper sheet embedded in the sand for heating up in the fireplace, i come across this even more brilliant idea! thanks!

[markirish]

Fantastic video from a brilliant channel . thanks for taking the time to film and edit the videos

It would be cool if you got into data logging and so could give us a nice graph of the temperature in the centre of the sand sampled regularly over the hours after lighting the candles. You could also graph the room temperature in a room that you keep the door closed on for the duration of the experiment and then go on to work out how many of these would be needed to heat a room of a given volume in your particular conditions and how long that number is able to keep that room comfortable just off the initial burn and sand-stored heat.

Love it! Now I'm sitting here trying to think of a way to utilize it to keep my cup of coffee warm Lol. Perhaps sitting another clay pot on top of one with candles, with spacers between the pots, so it doesn't inhibit the oxygen needed for the flames? Perhaps with a variation of this idea? : ) I enjoy and truly appreciate all of your content and how you strive to improve on every idea. TY

[monabouknight]

This one's a keeper! We no longer have a working fireplace and a power outage during the winter can be brutal. I've been watching videos like this for over a year and agree with you about trying to improve on these clay pot heaters. Going to try resting a scrap piece of copper across the tops of copper in the bigger pot and see if I can get my wood stove fan to pick up and disperse some of the heat. Either that or add a block of heated soapstone to the pot of sand. Anything for the cause!

Another wonderful invention from you, much appreciated and very interesting. Combine this copper strips idea with another recent idea from you. The copper strips can be stuck into peripheral sand around a smaller can in a paint can, the smaller can filled with carbon felt.

[MichaelR]

Great idea thanks for sharing YAH bless !

[GoodAllGood]

I wonder if making the copper U-shaped with two parts of the copper strips in the sand, instead of L-shaped, for the double tea lights, would heat even more. A peltier stove would easily sit right on top.

These are beautiful unlit, and even moreso when lit. You keep topping yourself!

[RossmanGarage]

Keep up the good work dude can’t wait to see what other stuff you come up with!

[HideBuz]

Nice idea, I would definitely incorporate a fan to increase the warm airflow. Otherwise you are relying on radiation heat alone, which is mostly IR and gets absorbed quickly once the view is blocked.

THose little candles in the jars can be bought at Dollar Tree for 1.25 and they last far longer. I use lots of both tea lights and Dollar Tree jar candles. Pretty smart design!!!
