This is exciting 😃
Glad you enjoyed it 😁👌
Congratulations, you made a storage heater. Literally around since WW1.
Cool I didn’t know that. 😎 bring back old tech 👍
Where do I find information on the old storage heaters?
Seems as though the fellow simply showed how to heat sand. Maybe I skipped the part where anything was especially "stored"?
@@user-br6qp7mi2m The sand stays hot for a long time
@@user-br6qp7mi2mit's stored if you seal it well enough. Either way if you have it inside your room. The heat escaping will be used to keep your room warm. But when you need more heat out of it. Just have a fan how through a copper pipe to take advantage of the rest of the heat.
Could you make a small scale model of a greenhouse with a sand battery inside to see how long the heat can have last ?
Maybe when I get some free time. I do have plans of making another smaller sand battery and using it to run a peliter fan some time in the future. Thanks for stopping and checking out my channel 👍
thanks, I live off grid in a very cold place, I'm looking into a sand battery, and wind turbine for power, making heat and hot water. I'm thinking 55 gallon drums of sand. there's just no information to be found. what is that heating element? I'm planning on a 12v element.
That heat element I used was a 12v 300watt water heat element. It would work better with a drum of water I reckon. The heat element would burn out to quickly in sand. Try heating water with a water heat element first and see how well it proforms.
you're going to need a TON of current with a 12v. Just use a 120v element and stack 2 35v solar panels together like I did.
Great video and project. Did you have any issues with the insulation on the wires from that heat?
I havnt checked to be honest. I will check tonight. Some high temp silicone wire would work a treat

It looks like the wires held up ok mate. But I don’t know if a sand battery is worth while on a small scale. Larger commercial ones with the mass and insulation seem more promising
@@Techboxreview Highly recommend using silicone wire. My wires melted.
Man that's fascinating I've never heard of a sand battery that like ancient Egyptian conspiracy theory technology so how do you re-use the energy from it or is it just to hold heat nice work mate 👊
Thanks mate. Yeah very intresting concept indeed. U can use the heat to heat a small room or green house. Or you can use a thermal electric peltier to convert the heat back into 12volt electricity. Some bigger sand battery’s run steam turbines to produce power. Very cool low tech energy storage 👍
We’ve all been interacting with sand batteries our whole lies we just never knew it or called them sand batteries…. we all just called it the beach and damn did that sand burns lol.
@Techboxreview Can you educate me how to convert it to power source?
I am think of using a sand battery to heat my greenhouse over winter and I was wondering how big a storage container I would need to keep a 2.4 m x 2 m area warm.?
Hi mate I couldn’t answer that sorry. It all depends on how cold your area gets and many other variables. I would rather heat a bucked of water. I personally think the heat element would burn out a lot sooner in a sand battery. Another idea would be to use an aquarium tank with a fish tank heater. I hope this helps 👍
First use a regular air heater. If you can find out how many watts the heater uses that'll be a a very helpful detail I could use to answer your question. Then I'll need you to tell me how long does the heater stay on before taking practice braids and also how long It takes it's braids breaks and I'll answer your question then. Because 1. I don't know where you're located so I need to know how cold it gets at night. 2. I don't know how well your green house preserves heat. Come back and tell me the results once your done.
Can you do the same with a solar panel and leave it out all day heating up? even if the panel was only 120w?
I’m sure you could. You could use a 120watt heat element to closer match the 120w panel. Something I may do a test on some day. Thanks for watching
Planing to do one in my back yard just curious do I need permission from council in uk
I’m in Perth Australia so I can’t say. You will have to check with your local council 😁👍
Grow a set just do it. Better to ask for forgiveness
How long did the sand battery hold the heat till it was ambient temperature again?
I should of timed it but was around 10hours
hey! it's a great simple set up. I just tried my own...with a 110 watt water heater from Home Depot...and it burned out pretty quickly. Is there a rule that'll keep the elements from burning out? Do I need to lower the voltage a bit? Maybe run on 48 volts or 24? I'm curious to know why no one on CZcams is burning out their elements. what do you think?
Hi mate. Are you just experimenting or you using it for heating purposes? .i think Although this does work and it is a simple to build. I think heating water with those water heat elements is more suited. I have seen some youtubers using PTC heat elements for sand heaters that seem to have a better resistance to heat. ( they will only get to a certain temperature from my understanding). You may need some sort of thermal switch or You could try lower lowering the voltage and see how it proforms.
Apparently water heater elements are not well regarded. A lot of people go with electric stove elements. expanded vertically to heat a larger area of sand. They will work on AC or DC and happily create heat with the only input being a solar panel.
@caretakerfochr3834 yeah cool. I will have to look into that. Thanks mate. I do have a couple small PTC elements I want to use to make another smaller sand battery as an experiment also
Will you be able to do experiment with +5 tons and insulation it will be beneficial to gather some data before I go a head
Just wanted to let you know subscribed and liked thank you for sharing the data 😉
@kingk5013 thanks mate. Welcome to the channel 😎
Is that a 12 volt heat element?
Yes 12volt 300watt 👍
It took a bit long b4 d metal heated. Why pls
Hi there. Sand is not the best conductor of heat so I takes longer to transfer the heat to the outside metal.
What power source did you use to run the heater element?
For the test I used a battery. But it will work with solar no worries 👍
@@Techboxreview would I need the step down convertor like in your previous video or straight from the solar? + With the element being a 300w appliance, to run directly from solar would I need 300w worth of solar panel or is that not how it works :)
These can be connected directly to a solar panel. There’s a ohms law calculator u can use to better match your heat element and panels. If you wanted optimal output of your heat element. www.watlow.com/resources-and-support/engineering-tools/ohms-law-calculator
To be honest it would may be easier to just heat up a tub of water. The high temps that the sand battery gets will shorten the life of the element I would imagine
We have a 4m x 4m insulated shed we hatch worm Eggs in. It has to be heated in Winter to around 15-17c. We're looking for a simple way not to replace the current heater but reduce the work load on it.
Hope its not the end of it cos i was waiying to see hoe you turnrd it into electricity
I may make another video converting the heat into electricity soon. I have ordered some things that will make it work 👍 thanks for watching
Would’ve been easier just to buy a fish tank water heater get like a two or 3 gallon metal jug fill it full of water with a cover and then bury that in sand set it to like 75 or 80 you should’ve been good to go
Thanks mate good idea 😎👍
@@Techboxreview hey no problem man I’ve been thinking of the same idea myself for a while now that there had to be a better way to do sand batteries on the cheap for the average citizen in the nation I was thinking maybe a 55 gallon drum a two or 3 gallon container put that in your seller on a cement floor maybe might be able to heat your whole damn house
@@Techboxreview I also had a another idea maybe building a sand battery around a rocket mass stove idea don’t see why that wouldn’t work either
I like your thinking bro. I love the idea of rocket mass heaters. I even brought a book about them. lol I would love to build one sometime in the future. Maybe I will make a video about it 😜I hope you are having yourself a great Christmas mate 🎅🎄🍻
So what is the point, You heat up sand then what?
To bask in its glory!! Obviously
Ok@@Techboxreview
Holds heat for a very long time
You have apartments that don't have heaters so when it's cold af and freezing you're using alternate methods of heat sources. Use a thermo fan to blow the heat in your room
Why didnt you SHOW THE POWER SOURCE .. ??? ..... YOU SHOWED EVERYTHING ELSE .. BUT NO POWER SOURCE .. NOT A VERY GOOD TEACHER 😕. .... WHY DID YOU NOT SHOW THE POWER SOURCE .. ???
It's 12v.
Regardless if it came from a squirl wheel or diesel generator. Frankly for an hour test, I would plug it in.
He said the heating element was a 12v 300W device. That comes out to 25 amps of 12v power. Look for a 30+ amp or so 12v power supply and you should be good.
Also, you’ll need thick wiring with a good amount of insulation since it’s both higher amps and in a hot, salty environment. Silicone insulation can take a decently high temp. There’s also specialty materials that may be more useful. Alternatively, you could put the element in like water heaters: from the outside. That way wiring is out of the sand
Thumbs down. The wires would melt.
Use some high temp silicon wire. Problem solved 👍
First it's not a sand battery it's a TES Thermal Energy Store. Next that element you are using is meant as a water immersion heater and has been constructed to withstand at max around 100 degrees Celsius on the terminal flange and the cables you are using are not rated for a temperature even that high. But you have them inside the storage space and subjected to the full heat of the sand. This gives people the wrong idea about how to achieve a home built unit. No thermal insulation, abusing the heating element and no output arrangement. what was the point of your video. We could all easily have imagined that the sand would get hot without watching you do it. Sorry to pour cold water on it, hope it didn't short it out.
All true.
Thanks for watching
No one mentions the heat retention. Clearly it gets hot, but for how long after powering?
It can very greatly. Size/insulation outside temperature. This small example held a good about of heat for a good 6 hours or so. I should have kept the video going and done checks along the way. Thanks for watching mate
@@Techboxreview awesome, much appreciated 👍👍
