- 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. - Наука та технологія
I've been watching you for around 10 years and this is the best one I can remember for this flower pot type heaters!
wow. thanks, I'm glad you've been a long time viewer. I've been wanting to find a way to add lots of thermal mass to the 'flowerpot style' heater for a while and this is the best way I've thought of. the copper grabs like 90% of the heat of the flame and just sends it straight down into the sand to be stored and slowly radiated over time. no wasted heat being sent to the ceiling (where you can't feel it).
@@desertsun02Good thinking 99! Seriously using your noggin there. Outstanding synthesis and execution of information different bits of information. BONUS: No cleaning spot off the walls, ceilings and furniture. That shyte gets EVERYWHERE. 🤦🏼♀️
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!
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.
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.
hi and thank you!
Super cool and the sand 'may' extinguish the candles if it is somehow knocked over too.
💡 That's a great idea!
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.
Fantastic video from a brilliant channel . thanks for taking the time to film and edit the videos
Many thanks!
Very very. Clever design. Awesome dude
Unique
Thank you for this
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
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.
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 …
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!
Great idea thanks for sharing YAH bless !
Impressive 👌
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.
hi. a small fan should work good with this 🙂👍
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!!!
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.
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!
hi and thanks 🙂
Your awesome!
Keep up the good work dude can’t wait to see what other stuff you come up with!
Hello. Thanks for the video and sharing your ideas. If you have time, maybe you can test it with fireclay mortar or, for example, black quartz gravel (the gravel can be placed outside in the sun, for example, in the summer) it will heat up and maybe release the heat at night... I don't know ;).. but if, for example, : you have these three curved copper plates, maybe you can put a square copper plate on them and a fan on it. Maybe it will get warm enough for it to work. Take care. Greetings from Poland ;)
Badass! I love your content
thanks 🔥
@@desertsun02 hey bro try erythritol instead of sand they use those in those sunpots and heat supposed to last all day
Brilliant
thanks brother 🙂👍
This is impressive, great job!
hi and thank you 👍🙂
I love this flower pot build! Do you think an eco-fan is light enough to sit on top of the copper strips? Thank you for another really awesome video!
Pretty inspiring content you got there, I've started gathering materials to test some ideas, heating has become expensive and the building main heater needs maintenance at time causing causing problems for days and even weeks so I feel it's crucial to have an independent free of cost solution available at all time.
How about a small can? I have 2 and was thinking of doing this per room.
thank you for this video, you don't know how much you've helped me prove my theory with my energy generator system, i don't have much money to keep experiment and here you are doing just that. you are a god send, keep up the work brother. if you're interested in what i am doing and you can experiment on it and show it to the mass that'd be awesome too but for now brother keep doing you.
You're very welcome!
Great job. Looks lovely too. What is the temperature of the pot? Surely it is inefficient to heat from above as heat rises? I'm thinking of making one where the copper is heated from below.
Would it be more efficient if instead of an L shape for the copper, you use a U shape? Twice as much copper in the sand.
hi. i'm not sure if the shape would affect the efficiency but the issue with the u-shape is that it's hard to find copper that is long enough. you need the pieces to go far down into the sand.
Hey ds I wonder if you put a smaller Clay pot on top im guessing the smaller clay pot would radiate more heat to the sand and outside the pot. I might try this one.
Hey!
Thank you for all your help.
I have a question.
Could you cook with a pot on the copper ?
Or are there any ways to cook with the heated sand?
Thank you very much
Why not bend the copper twice so the copper goes down into the sand from 2 directions, kinda like the thing you made with the 2 pieces of copper and 2 candles? Also, I realize that copper is expensive, so why not mix scrap or recycled copper in with the sand?? Would that be better than just plain sand?
Could we use Aluminium strips to do the same as the copper? or would it corrode etc? Prices of copper in the UK is expensive even the cut offs.
Any food dehydrator videos coming up?
Great idea. New sub😊. How large of space does it heat and how long does it heat the space? Is the outside of pot hot?
hi there and thanks for subbing! i'm not exactly sure how large of a space it can heat. i guess it will depend on how much you need to raise the temp for a given area. standard size tealights will burn 4 to 5 hours plus the unit will release heat for 3 or more hours after they go out so you could get 8 or more hours from one set of tea lights. they also sell long burn lea lights. those burn 6 or 7 hours so you could get 10 or 12 hours of total heating if you use those type. the outside of the pot gets very warm and continues to warm the longer you run it. very warm in 45 mins to an hour and hotter as time goes by. (up to a little under 300F/150C within 2 or 3 hours). if you add a second candle under each copper strip you can get it to near 400F (the copper) and the sand temp stays a little under that (350F/177C).
Love your channel!!
Here's a challenge for you..
Heating air space is such a waste...
compare to...say ...hot water bottle...placed to heat arthritis...which is amazing efficient...
But ...what other (efficient) ways are there to heat the body... Directly...without wasting heat on air space...
Maybe...heated seat...??
The point is , though, not to have EMF near the body...not go mess with the body natural electricity...
I know infrared radiation is not heating the air...so...how to generate infrared heat (radiation), without wasting energy on the other 2 types of heat transmission (conductive...and ... what's the third called...about hot air...??...on second thought...i believe it's called convection...
Can you use one of the heat powered fans on that? Maybe placing a flat piece of copper on top of the three pieces of copper.
i couldn't say for sure but it might work good
Put the thermometor into the sand but not directly over the flame, to get a better reading of the radiant heat function. And how long does it retain heat after the candles go out?
So how far does the heat radiate from the pot, how close must you sit to get any benefit from it, and how long does it last.
How well would it heat up 35 foot room,in emergency?
Do you know whether the gradient of the sand would make a difference? Finer sand absorbing quicker? Just wondering. Incredible design. Looks cool too👌
hi and thank you. i'm not sure if the type of sand makes much of a difference but i would guess the finer the sand the more heat it holds (because the grains fit more closely together). i used a fine off-white 'play sand'. it's cleaned and filtered (usually used in sandboxes etc.)
@@desertsun02 thank you 👊☯️👊
I am wondering how do pot heaters make candles more efficient? The heat gets released either way, just slower in this case. Or am I mistaken?
hi. without the copper and sand, most of the heat from the candles (90% of it) will just go straight up to the ceiling where you won't feel it. using the cooper allows you to 'grab' that heat and store it in the sand (where it will radiate the heat slowly into the living space (the bottom half of the room) over time).
Hi Desert Sun 02,
I have some scrap copper water pipe I was going to recycle. Would that work as an efficient substitute?
You did not ask this from me but I'd hammer it flat and bend it to get more efficient heat transfer than thinner plates. Of course it depends on the size of the pipe.
Hi there brill idea what's the thickness of the copper
it's 24-gauge copper (99.9% pure).
Work with an alcohol flame as well?
i bet it would. might get even hotter than the candles make it if you used an alcohol lamp.
Fascinating build that I would love to try! However I would be really careful of using cheap paraffin wax candles. They're made from petroleum and releases carcinogens and toxins, creating indoor pollution. Better to use beeswax or other natural fuels for healthier air in your home.
👍
Wish you had a link for the copper...
I always worry that I'm getting the wrong thing.
Thanks!
it's copper from 'flashing kings'. sold by the pound. 24 gauge. 99.9% pure. i just buy the scrap stuff. i get it on amazon but you can probably get it at places like Ebay and Aliexpress too.
what type of sand? would finer particle size be better?
hi. i used an off-white fine 'play sand' (generally used in sandboxes). very fine, clean and filtered. almost has a 'soft' feel to it.
How much area will that heat?
Think this would work with a stove fan on top?
hi. it would work for sure (but you'd want to use a lightweight one or it might press the copper down onto the candle flame over time).
How long does the sand stay above 100F after the candles go out?
hi. i'll have to test that to see (but it heats for several hours even after candles go out). i'd guess at least 3 hours
Why not make the copper plates boxed at the top with just the front open for air and lighting the candles... catch the heat escaping from the sides,.
Where do you get copper like that?
hi. amazon is the best place i know of
I bet someone out there will call this a "Sand Battery".
Now we have to figure how to make candles that will burn for at least a week at a time....
that would be sweet.
@@desertsun02 ..would proly make a lot of rich local oil men poor and put a nice dent in gas & electric profits if most of us adopted your ingenuity ...i think i can speak for many when i say you are greatly appreciated dude👍
How about burying a 12 volt ceramic ripple elements in the sand. They should heat up in a hurry.
If they heat the Bricks on the other project , it should heat the sand? Worth an experiment.
hi. that would work. i never used the ripple ones in sand or gravel because they are generally made with fins and used with a fan (but you could). i go with the ceramic ones with an aluminum shell. no fins on those and they have the same type of ceramic element. i just re-read your comment, looks like you were talking about the ptc ones (with aluminum shell). those were the ones i used with the bricks. those work good in sand for sure
@@desertsun02 yep use the ones you used with the Bricks, and put them right up against a a copper strip, 4 per can should do it. Then put some copper strips on the top and use a heat driven fan to blow hot air. Should work well.
hi. i see what you're saying. yep, i have run the heat fans with the ptc elements. all you need is 2 of them and the fans will crank. you don't even need copper. you can just set the fan right on the elements.
@@desertsun02 Glad you’re doing all the experiments that I need answers for, I’m looking to get my 10x12 greenhouse to 16C so I can grow cool season crops in the winter. I have a VEVO SS tent stove, could fill it with Sand and put 6 or 8 PTC elements in there, and a Fan on the top. Other Alternative is to make a vegetable oil Burner for the Stove, but would be more expensive to run, I could use solar Panels (200 wats) on the greenhouse to run the PTC elements off a battery bank, sun is free, and the greenhouse faces due south.
Spent all that $ to heat 3'.
hi. doesn't really cost very much. about 6 bucks worth of copper (about 1/3rd of a pound), $1.00 for the flowerpot (dollar store) , and tealights are about 10 cents each. plus some sand. maybe 10 bucks for everything.
Great vid- as always
IDEA- put twice as many - facing inwards
Put inside an insulating box-made from plasterboard/ sheetrock,with rockwool insulation on 3 sides of the pot
On the 4th side, put a slow fan, powered by a peltier
Then measure temperature at 3 foot distance,every hour for 8 hours
PS
please get as close as possible when shooting temperature gauge,etc
On a small phone, very hard to see
