DIY "Dutch Oven" Air Heater! (w/Sand for Heat Storage) - Radiant Sand Air Heater - Cooks too!

Off-Grid Air Heater using a cast iron dutch oven, a 'camp stove heating over' (the cylinder) and some sand. powered with liquid fuel. looks cool. lots of heat. easy diy. the sand holds (and radiates) the heat for hours. 3 fuels tested. note: the top 'doubles' as a stove burner (boils water in only 3 mins). for indoor or outdoor use.
note: the main part of the video goes to the 5:35 mark. then from 5:35 onward i show the "progression" of the project (including how it all started, and several early models of the unit).

Fascinating! I've encountered all of the Parts for this heater but would never have thought to combine them. This why I've watched and taken notes of Years. Fan compatible ? THANK YOU AGAIN.

[@desertsun02]

Thank you! - I'm glad you like it. 👍🙂 (you should be able to use it with a heat powered stove fan)

[@pamelajackson6937]

You're fantastic! You don't disappoint us with your amazing creations. ❤❤❤

[@desertsun02]

Thank you very much!

[@stephenhickman9502]

I know you are an expert and I will never doubt your skills and engineering but please be careful bro. That methanol can get out of control in a blink. All that being said, this heater I'm actually going to build. This one seems super efficient. Thanks brother for helping us fight what's coming.

What an excellent video format. I'm usually F-FWDing to just get to the point..thinking, "just let me see everything you used, I can figure it out myself". You immediately showed every component you used and how, without a bunch of over-explanation of the obvious.. so much better than a 20 minute, camera all over the place video, showing 5 minutes of actually meaningful info. Well done. Everything u need to see and hear, with results - no waste. SO appreciated 😎👍

[@desertsun02]

Glad you enjoyed it! yes, many people ramble on and on in their vids. i know the frustration of watching that type of video. you can watch some of them for 10 minutes or more and not learn anything of value.

[@svenshanah]

@@desertsun02 Exactly. 👊👍

[@russellrlf]

I would have never guessed the sand at the bottom would get that much heat. Impressive. Thanks

[@desertsun02]

yes, since the base of the flame is super hot, it heats the sauce cup and sand very fast. (the temp test i did was after just 15 minutes). if you run it an hour the sand temp can double and even triple.

[@russellrlf]

@@desertsun02 I am going to make something like this for using in my small canvas tent. Warmth for winter camping

[@andrewsolano9172]

@@russellrlf tip for EXTRA tent warmth.....get a 1 or 2 ban tent and set it inside a bigger tent to sleep bigger tent blocks some cold and wind and smaller tent retains heat

🎉The desert sun in Arizona continues to stimulate your brain to create affordable basic comforts that we humans crave. Many thanks for all of your creations and more so, taking the time to share them with the world. 😘🧓

[@joecool4656]

Very cool. Make sire that you only use fuels that do not leave soot on the metal. If it is leaving soot on the metal then it is also polluting the air you’re breathing. For another project idea, try modifying an oil lamp. You can have the sand thermal mass around the clear glass tube. The flame would also be adjustable. Make sure you only use compatible fuels though so you don’t overheat the glass or have a flame in the fuel basin below the wick

[@stevew6138]

Interesting. Thank you for so many ideas.

[@jameswilkins8530]

Outstanding!

[@desertsun02]

thank you! 🔥

[@andrewsolano9172]

you can also use those steel enamel pots that you see at segunda all the time for dirt cheap

[@kartof1]

Very interesting and useful inventive development. I've heard the best stone for thermal mass is soapstone from Pennsylvania but I don't know if it can be obtained as sand and it probably doesn't matter even if it can.

[@journeywithnichole]

Wow thank you! Been looking for a back up for my back up. Does the bio fuel last a long time, similar to oil lamps?

[@AereForst]

I think a copper band going over the flame and underneath the sand would help heat the sand faster

[@mooseguyable]

Infrared heaters use electromagnetic radiation to directly heat objects or people in a space. They are known for their efficiency in quickly providing warmth.

[@klee88029]

06:16 Probably the paint burning if it is a painted black lid. Nasty!

[@desertsun02]

hi. yes, i tossed the lid. not sure why they used paint on that part

[@annnonomys3132]

Thanks for sharing your creations. Question. Roughly how much alcohol for how much run time? You said about 2/3 full. But the size of sauce cups vary. And later you made a reference to burning at 25 minutes. But it appeared that was mid burn. Can you give an idea of length of burn vs quantity of fuel? Thanks.

[@andrewsolano9172]

you can also take and preheat it on induction burner give the sand head start on heat retention it may last all night (the heat radiation that is)

Wow Light/Heat/Cooking 🥰 TY❤What is the Cleanest most natural fuel to use??

[@desertsun02]

you're welcome 👍 (the bioethanol is the cleanest. the brightest is probably the denatured alcohol and i'd guess the methanol is the hottest)

[@theresad6990]

Have you tried this using canned heat/sterno fuel? I'm wondering if this would provide the same results. If you put a flat cast iron griddle on top you could cook on it or put a wood stove fan on it to circulate the heat as well.

[@desertsun02]

i haven't tried canned heat but it sounds like a good idea. ✔🙂

[@s9josh778]

That's a good looking heater. Also, do you need a Go Fund Me for a HVAC system bro?? :P

[@mannyfragoza9652]

Great idea, i know this will throw huge amounts of heat. What is that cylinder thing?

[@desertsun02]

hi. it's called a 'camp stove heating cover'.

[@mannyfragoza9652]

@@desertsun02 cool thanks

[@DdDd-pk4pu]

TY❤What is the Cleanest most natural fuel to use??

[@desertsun02]

hi. i'd say the bio-ethanol is the cleanest. only puts off a little carbon dioxide and water vapor when it's burned. (but no smoke, odor or fumes though and the carbon dioxide output is very small - only about the same as having one extra person in the room). to find that fuel just search for 'indoor ventless fireplace fuel'.

[@SaintTrinianz]

Where would I find the slotted cylinder? Is there a link?

[@desertsun02]

hi yes, you can find that along with the 2 quart dutch oven on amazon. the dutch oven is an 'amazon basics' 2 quart one and the 'cylinder' (the camp stove heating cover) is a 'bulletshaker' camp stove heating cover. (amazon has other brands of those too). here's a link to the 'bulletshaker' www.amazon.com/Camping-Heater-Warming-Heating-AdvancedShop/dp/B0768H9BJQ/ref=sr_1_2?crid=EVIO0D3NWJ9Y&keywords=bulletshaker&qid=1704568806&sprefix=bulletshake%2Caps%2C371&sr=8-2

[@AShroudOfTruth]

So where do you get your white sand?

[@desertsun02]

you can get the sand from the home stores. home depot and lowes sell 50lb bag for cheap (low as 5 to 8 dollars)

[@theresad6990]

@@desertsun02 did you use "play sand" or "construction sand" or does it make much difference? One is coarser than the other so I'm just wondering.

[@desertsun02]

@theresad6990 i just use play sand. i don't think it would make much difference. (but play sand might be a little better because the finer the sand the closer the grains will fit together).

[@ericb2247]

Friend, what would make your channel stand out is to do real data analysis and comparisons between fuels, materials, emissions, performance etc.. I think it might drive your innovative process too!

[@ericb2247]

for example, does sand hold onto and emit more heat than water or concrete or solid steel?

[@paulsansonetti7410]

Cheapest source of fuel online suggestions? Thanks in advance

[@desertsun02]

hi. i'm not sure of the cheapest. the denatured alcohol is pretty reasonably priced.

[@AereForst]

@@desertsun02Used cooking oil probably. Strain with coffee filter and convert to lamp with large wick to increase heat output

[@panagiotiskarelas5063]

Maybe some more information are needed to be told in these videos. For example 1) weight of thermomass used as sand 2) weight of fuel being used 3)how long does the thermomass maintains a warm temperature 4)can this heat a room. etc...

I wish i were in Arizona :-). Where i live everything is forbiden except what is allowed. I would be fined heavily to do such experiments. Better not to put on youtube 😂 America unleashes creativity and potentialvwhich is punished elsewhere.
