I really like the safety with this build. I'm having troubles with my flimsy solar panel charging my power station. I think I'm going to use a 5qt cast iron dutch oven with handles, so I can heat my sand on a small round grill outside using 10 charcoal briquettes which means a 16 lb bag of charcoal @ $35 has enough briquettes for a month.
@@desertsun02 Oh wow, I just noticed that I have most of the parts, as last year I bought them when I saw your first brick radiant heater including the thermometer. ua-cam.com/video/pIvDD3e26DY/v-deo.html
Really like and appreciate the types of tinkering that you do. I'm interested and view your projects with a slant toward boating and liveaboard use cases. What I need to know about this (and almost all your projects) is 1. How much AMP draw? 2. With the sand battery applications, how long does it hold the heat, and how much heat is being held over time? We can get solar panels to heat the sand directly during daylight hours, but how much battery power will we need to keep it going after daylight? Hope you can see where I'm going with this. Thanks for the videos. @⚓️👨⛵️
Maybe you have videos that i haven't seen yet, but it would be awesome to see how much this could heat a room up to and what size of room is best. Great channel!
I would actually place that fan down on top of the upper heat plate, but in fact utilize two fans as well, so as to transfer as much heat as possible! But now when mounting those fans directly onto the upper plate, I would also use some heatsink compound that is used for PC processors in between the layers AND clamp the fan bases directly onto the metal plate so as to insure them NOT to be moving around on you! The compound paste type that I would use should relatively thick and has the properties of not drying out easily such as to form a hardened paste. Once all of that is done, then place the sand into the cavity such as to cover over the fan base flanges while maintaining a sand depth upwards of nearly an inch and a half's worth! Then but then you'd have a pretty good blast of heat coming at yah! Yes, around 140 degrees worth or better! You could also use the same kind of heatsink compound on those Peltier devices that meet up with the upper plate as well BUT you actually should use a machined piece of aluminum that is at least a half inch thick I would say. Those Peltier devices should also be clamped down secure from underneath the upper plate somehow as well.
Awesome, love seeing your videos! Do you run any from USB at all? I’m in a converted short bus (18’)and have 4x150 watt solar panels w 2x200 ah gel batteries. I’m trying to heat a sectioned off bed space less than 12 sf. Not sure what my USB or cigarette charger will pull to power to do this or how many heating elements I can power.
hi. i posted a link to the unconverted (original) oven project in the description section below. that video shows exactly how i put it together. Basically, i just wired the elements directly to the power source. those type of elements can be connected directly to 12v solar panels or 12v batteries.
In a real-world scenario, how long does the T.E.G fan run for after the heating elements are deprived of power? I imagine that the idea in a thermal-mass battery is to have the heat dissipate over a longer period of time than the original heat source (in this case the sun) can provide. In effect, after the sun goes down, how long does the T.E.G fan run for ?
hi. they can run for a long time. the fans starting temp is only 122F/50C, so as long as the heat source stays above that temp the fans will continue to run. a smaller setup can run for several hours after the sun goes down - and as you increase the amount of sand (thermal mass) these setups can run fans for several days or even weeks at a time.
What junction box did you use or can you use do l could plug it into a 240 volt socket here in the UK , do I need a step done system or unit to go from 240 volts down to 12volts , you’ve 6 heaters in your video so you must of used something like a junction box to take 12 wires , sorry if my questions are stupid = really don’t know much about this stuff .
hi. since the heating elements are 12v i just hooked 3 of them to one cable and 3 to another and then put those two cables to the power supply. if you watch the original video (the one where i was using this as an oven) it shows more detail on how i hooked up the elements. the link for that video is in the description section (below) 🙂.
@@desertsun02 I did watch the video but couldn’t get the link to open , which video was it that shows what you did with the wires ? I don’t know where you are in the world but here in the UK our plugs have a three point plug = live , neutral, earth, how did you earth those units.
Have you tried powering it non-stop with photovoltaic panels for a long time? I heard that being in the sand they burn out easily and don't last even a week.
hi there. what you heard is completely and totally untrue. these types of elements are extremely tough and durable. i couldn't get one of these elements to burn out if i tried. they literally never burn out. they can be used in sand, dirt, gravel, and just about any other dry material you can think of. it doesn't hurt them at all (they are made to run dry). i've bought and used at least 80 of these elements in dozens of projects over 5 years and i've never had one fail. i've had a 100% success rate with them. they are rated to last for years (running 24/7) in very tough conditions. i've yanked on the wires, washed them in water, applied voltages way over their rating, placed them under great physical stress and heavy weight and they hold up perfectly. they are as close to 'indestructable' as you can get. Sorry for the long-winded answer but i really wanted to set the record straight. 🙂
@@desertsun02 I have 20 cm ptc heaters myself and I managed to raise the temperature of 2x 20 kg metal plates - designed for Olympic barbells to about 70 degrees using two of them. On youtube under the film "Sand Battery Home Heater for Solar?" - youtuber - mvpmachine - wrote that he broke a few of them because he didn't dissipate the heat from them quickly.
@dawidkujawski3340 he must be talking about peltier modules or peltier chips. (those look similar and also create heat) but a peltier module (peltier chip) is something totally different. it's a different technology. you have to dissipate heat off of the peltier ones quickly (with a heat sink) or they burnout. the heating elements i'm using are called ptc heating elements. you don't have to dissipate heat off of those.
Neat idea. A heated sand bed. Sand up your butt jokes aside, a water bed bag mattress filled with sand, perhaps. I bet a waterbed heater might run directly off uv panels
@kenyahawkins2472 i see possibilities with that idea. i recently ordered some 'low heat' elements of the same kind. (i usually buy the hottest ones so i decided to buy the lowest heat ones). i was thinking of making 'heated clothing items' with the low temp ones. they just get warm but not hot. but using with a chair or bed might be possible.
they are known by a few different names including... positive temperature coefficient heating elements, ptc heating plates, aluminum shell ceramic elements, ceramic stone/tablet elements, self-regulating heater, self-regulating heating stones and probably a few more.
Ive watched your videos for years. Your imagination is next level 👍👍👍

that's a good idea. i'll do some tests with it
Renewable energy companies should have you onboard as a consultant
That's another thing I have to make now!

Thank you too

Approximately how many feet from the sand heater IS "way back here"?
How about putting it in sand to create a sand heater?
In a real-world scenario, how long does the T.E.G fan run for after the heating elements are deprived of power? I imagine that the idea in a thermal-mass battery is to have the heat dissipate over a longer period of time than the original heat source (in this case the sun) can provide.

What about an armchair or even bed design.. built around a solar power - heated sand battery ? Sit and sleep in warmth ..
