- DIY "Copper and Brick" Thermal Mass Space Heater! Radiant Brick Space Heater with Copper Plates! made with two 5 pound 'stone bricks', two sheets of 24-gauge copper (99.9% pure) and 4 12v DC powered heating tablets. the heating tablets have an average heat output of over 300F/150C (with max rating of 428F/220C +/-10%). the elements heat up the copper plates to 300F/150C in seconds (which then quickly transfers to the bricks). the elements heat up in seconds and within 10 minutes the bricks are fully heated. for extended heat distribution a small fan can be used. a 'heat powered' fan is shown in the video. all you do is set it on the hot bricks (or hot copper) and it runs. if you like the video, please share it around with anyone and everyone! 👍🙂
Couple of final thoughts...
🟢 The DC powered heating tablets (also called PTC heating tablets) can be powered using a 12v battery or a 12v solar panel (so the unit can be run 'off grid' if desired). unit was pulling around 10 amps during testing (measured around 2.6 amps per element). average total power draw of the heater (120w)
🟢 I made a similar unit with no copper sheeting a couple of years ago. it works good too, but it takes over 2 hours to fully heat up the bricks (versus only 10-15 minutes with this newer unit). adding the 2 copper plates makes a huge difference in both how fast the bricks heat up and how hot they get. the bricks in the older unit got to 200F in about 2.5 hours but the bricks in this newer unit get to 272F/133C in only 15 minutes. *so the unit can be made without the copper (but be prepared to wait a while for the heat).
Dude I'm so impressed with this that I bought a smoker grill on clearance and got a sailboat switch panel and 8 of those elements and firebricks with copper I'm rigging it all up right now.
Links for what you bought plz.
good idea !!!
I have done this, but amazon sent me 220 volt heaters, 130 watts. so I used 2 of these directly to mains. UK supply. They also come in 110 volts. This means you dont need a transformer. The results were similar to yours, amazing. I do think a fan is nescessary to spread the heat. I think when winter comes I will be able to heat one room for 25% of the electricity I was using. regards Colin England.
that's great! 👍👍
Hi Colin, do you have a link for the ones you purchased, also if using in a shed would it be best to get a fan?

Colin did you build the heater like this and does it really save electricity?
Yea ....!!!
Make a winter video ...
Test ur ... claims ....!!!!!😂
If the bricks had holes in it, it would heat by convection aswell as radiant heating, convection works more efficiently with a radiator than just a hot surface.
Set this up in a cook stove with the stove door open a few inches. The entire interior of the stove would also heat and the fan would push it all out the small opening.
i haven't tried that yet, but the fans work great on a burner. you just have to make sure the burner doesn't get too hot
@@desertsun02 those fans work by having it cooler on top so they won't work in an oven. They need a hot bottom and the air cooling the top which is a heat exchanger. Those peltier devices have a not and cold side. If you apply power and dissipate the heat on the hot side, the cold side can drop below freezing.
Be interesting if you mixed copper into the clay, fired it on a low heat and see what the outcome was. "Thermal brick". Could even modify it, to replace an Ondol system.
This would be an interesting idea for subfloor heating, just have to figure out a way to make it fireproof
Any way to use the fans to generate enough power to keep this thing going on its own after it's up to temp?
Another brilliant design , can you put a link to the fan and the heat pads , Please ? Thank you for taking time to teach and share , much appreciated .
I hate when they don't do that. Looks like other ppl are asking.
I hate it when people put amazon links for every lil shit, on top of ruining any other business and making bezos richer, seems like people need to be spoonfed even the tiniest details without even teying with what they have available.
@guachingman OK. Well, where else are you going to find these things at your fingertips? The reason it works the way it does, isn't because of Bezos or small business's. Sure, it sucks. But..... not everything is found *down the street*. Amazon is successful due to that matter. I'm not going out to hit 30+ stores to never find something, Sure I can go to Home Depot/Loews. But I prefer not to. Let people do what they wish with THEIR $$. Kinda mine your business.
In term of tempoeral inertia (for radiation), what is the best option between the brick or the sand solution ?
I was thinking to try brick on bottom, and a bread tin full of sand on top.
Excellent video, thank you! This should be able to hear my RV and also my 10x12 lofted tiny house.
You're welcome! i'm glad you like the video.
Super! So simple. Clear demo and very helpful. Thank you!
you bet and thanks!
Where do you get heat pads?
@@lawrencedobesh776
Could put a timer on it, run for ten minutes or so then off for two hours of it holds the heat like in one of your previous versions. Might help to reduce electricity usage. Also I wonder how aero-cement would work so it could be lighter? Great idea btw and thank you for sharing this!
Get it to run off a solar pnel-off-grid heat
@@SunnySydeUp:
I think the same thing.
How would one employ a timer if running directly off a panel to battery? Must an inverter be used , or is a charge controller suffiient? TIA
I would love to see difference in one heat element and fan with Cooper and thinner flat walking type brick, then 2 , 3 , so on heating elements all 12volt amp draws for each separately and together. I would also like to see if any amperage regulations are added or not and size of a 12volt battery used. Most us people need a 12volt safe in vehicle heater. Maybe the copper or brick could have a extra connection like a back wall for the air to pass and heat up more air.
Would using fire bricks work the same as the stone bricks? Or does it need to be the stone bricks?
My first home used this exact same heat storage method back in the 70s, by the 80s is was considered to be total crap and everyone changed to gas central heating.
Very old tech, the Romans used it 2000 years ago.
Yes, that's great, heaters between copper plates, you gave me the solution for ma sand stove. Now I have to create more electric power!
How did it work for the sand stove? I was about to build the same thing.
@@nyhost101
With 12V it takes a lot of time and power to heat the stones. With 220V and a heater wire it is hot in several minutes. (floor heater wires 220V)
The same with 12 V is almost not working. 24V would be better.
Thera are silicone wires for 220V and for 12V , they work ok, only 12 V a little bit slow and not so hot. So, I still need to find another system of power in my house.
@@fransjebik8554 thanks for sparing me from this one..im trying to heat a pool with some copper piping so maybe ill just make a small fire pit under my sand and copper pipes and see if that would be more effective.
This uses 8% of the electricity of a 1500w space heater.
I would pay $10 to run a 1500w space heater for 24 hours straight in Connecticut.
This set up uses only .80 cents.
hi. plus it's DC so it's easy to hook to a 12v battery or a 12v solar panel (if you want to)
Plus you could have it on for only 10 minutes an hour to keep the bricks hot.
Wow wow wow...thanks....do ptc heating elements heat on both sides or only from the top?
hi. they heat on both sides
The little white chip in the fan is peltier diode.
I wonder if there would be any improvement by covering the surface of the bricks with heat transfer pads... many thanks for your very instructive videos and for sharing your accomplishments.
hi and you're welcome. i can tell you that i've made these units with and without copper plates. the copper plates help in a big way. i was very surprised how much they help.
Hi, thanks for an informative video. Can you heat a room with this? How many watts does it use and how big a resistor do you have per unit?
Now, what about a low-cost housing for it to contain the parts inside to make it safer? I'd love to build something like this for my mom to help with her heating bill, but she has pets and I know that would be her first concern.
hi. always use your best judgement but i'd say it's very safe. pets will stay away from hot surfaces usually. i've had several wood stoves and i've never had a pet (cat or dog) mess with a hot wood stove. the unit's heat is self-limiting too so the unit won't get over about 300F/150C. the heating elements are made that way. it's hot but not 'stove burner hot'. it stays below the flashpoint of fire for most items too. meaning that it's not hot enough to start wood or paper on fire.
@@desertsun02 thanks. I'll have to cook up a sales pitch and something appealing-enough looking for her. Great stuff, thanks!
Hi Russell,
I would say that with those temps, try this... I would NOT use anything plastic! A lot of newer heaters use plastic... and they wonder why so many get recalled - duh!
If you can find an older heater with a bad element and a METAL case, pull that part, remove the old guts, and install this setup.
Personally, I would still like to see a thermal switch set at like 350 degrees that would shut down the unit if it gets too hot.
@@jptucsonaz8503 thanks! I was thinking I may have an old metal computer case somewhere that I could modify a bit. Maybe even put extra bricks in the bottom to prevent it from being tipped and just cut a couple holes in the top with a hole saw to let the heat out.
@@russellborrego1689 That would work too, just leave the plastic front covers off. I hate the smell of melted plastic!
By the way, the extra bricks would also help with long term thermal storage (thermal inertial, if you prefer...). So the whole thing could become quite a useful little backup heater for a whole room.
Love your vids! I would like to employ this in my 6 x 12" lean-to greenhouse to offset/eliminate the regular heater which is on a thermostat and could kick in when my 12V lead acid 35Ah battery runs out at night...if it actually does. I have both a cracked 200W panel and a new 100W. I'd like to just use a charge controller to protect the battery, skipping an inverter if possible. The controller I have is a 500W. Is the 200W panel too much imput, even with the controller? Your thoughts on this are greatly appreciated. TIA
Hi. Been following your channel for many years and have used your cooling unit in my Arizona strawbale house. I want to make -20F ice. Is this something you could help me with? Thanks for your time. Love the channel.
hi and thank you for being a follower of the channel! i don't have any videos at this time on the super cooling ice. i'll look into it 🙂
Brick heaters like these were common until the 90s
Are each of the PTC elements range wattage 5 to 50W and temp 220C?
hi. that is how they are often labeled and sold. they will pull about 2.5 amps after the first minute or so. (30w). the 50w can be in the first few seconds after startup and lower than 30w can occur once they have been on for a while. the heat stays constant but the watts can vary. i saw 2.5 to 2.6 amp draw pretty steady after the first 5 minutes
nice work DS.. is the 12 volt inverter plugged in to the ac wall socket or solar panel ? tia :)
What he is using in the video is a 120v to 12v “converter”. This is so he can use the 12v electronics on regular house power. This unit could actually be wired directly into a 12v solar panel or a 12v battery.
What's the energy efficiency input/output of this vs a standard ceramic heater or an oil radiator heater?
The efficiency is the same since almost all energy is waste heat. The fan heaters have some looses from sound and air movement, but this gets turned into heat in the room too once it interacts with objects
A big question comes to mind: If I want to run these type of heater setup directly from 400watt ~38V ~10A solar panel. Does the PTC element suffer from higher output from more powerful panels or does it only use what is needed?
hi. the ptc elements only draw what they need. (but the panel has to be a 12v panel (if the ptc elements you are using are 12v). i have seen 24v, 36v and 48v ptc elements though. i would probably buy the 36v ptc elements if i had a 38v panel.
Hey DesertSun02. Love your channel. Which do you prefer for heating, this double brick method or the sand battery. I know sand batteries are popular right now, but I’m leaning towards this double brick method being better. What are your thoughts???
hi and thank you. it's hard to rank them. both work good. this method works very well (especially if you use the copper plates). sand batteries are great too. i've got a new video coming out on that soon. (maybe this weekend)
Where do you buy the parts? And what are they called?
hi. the bricks are from home depot. the copper is 24 gauge and can be found on either amazon or ebay and the heating tabs are 12v 220C PTC heating elements. they are sold on amazon, ebay and aliexpress. they are usually sold in packs of 2.
How do I connect the wires of the heating elements to some sort of plug to plug it into the 12 V power supply? Is there a male version that I can order on Amazon that would fit into the power supply?
This sounds similar to a ceramic heater + fan that I bought from Big Lots for 20USD that uses
120VAC at 12.5A that can keep my bedroom warmish (door closed) on a cold day (high 30s F).
BTW,
what if the bricks were thinner or had additional external copper plates with radiation fins.
Could this be used to heat water instead of the bricks, then pump the water through a rad? I know the air wouldn’t get as hot this way, and would be a more complex process but the heat would last longer. In my application, I would want warm air for a very long time as opposed to very hot air for a shorter time. Thanks
Heating water pour in bottle, lasting heat.
try using sand. It stays hotter longer. Maybe use a basic thermostat also.
@@christophershultz1620 I have a system already in place so I can’t really change it. I have 25 IBC totes in a greenhouse, filled with water that gets heated up during the day and gives off the heat at night when it freezes. It would be great to be able to heat the water with solar panels or AC when necessary to keep the water warm. Thanks for the suggestion!
@@christophershultz1620 Sand seems too messy for fan use.
@GEAUXFRUGAL are you from Louisiana too? 😊
Do you have any other ideas to increase the heat output and increase the efficiency of the unit Sir ?? Nice work too.
combine the bucket idea on his channel with this

hi and thank you!
Hi Desertsun02,
Could you please provide part #'s and sources for everything you show here...
The heat units, the non electric fan, the stove thermometer, and the copper plates.
Btw, I didn't see you use any thermal compound for heat transfer, did you use it, and we just didn't see that part?
What is the maximum output rating of the RoyPow 12vDC adapter - I am guessing this is the 180W model which has a rating of 12vDC at 15A
hi. that's exactly right 👍🙂 (heater draws roughly 10 amps).
@@desertsun02 size of brick?
@Eric Benko they're 2"x4"x8" (flat sided stone bricks). places like home depot stock them. roughly 75 cents each 👍
love this dudes voice, super 'fancy' XDXDXD
What would be the best use for the PTC heaters? Brick, sand or salt?
hi. that is a good question. they all work pretty well so it might come down to what you can most easily get. i like the bricks and the sand ideas the best. the salt works good too (but i can get sand a lot cheaper)
Would adding thermal conductive paste to the PTC heaters and the copper plates and maybe even between the copper and the brick aid in it's thermal conductivity or transfer faster? I was using thermal paste alot I'm experiments for heat ain't worth shit for cold transfer also maybe try graphene film idk cool stuff thanks for the video
Hi! Interesting project. I missed the heating pad's power rating.
Hi! It’s in the video notes. Around 120 watts.
@Ville Nevala hi and thanks. total draw of the unit is about 120 watts
Thank you both but that is the power draw of the heaters in this setup. I was interested in the power rating, how much power can I use to warm pads like these.
@@Teknopottu These are 12V 30W pads each drawing around 2.6A.
@@pgpilot3884 Thanks alot!
What's more efficient/cheaper to run? A sand version with a hot water tank element or this brick version using the copper plates?
Have you thought about using a top brick with holes in it? I think they're called cored bricks.
i've been looking for those bricks with the holes (for a different project) but i can't find them in my area.
@@desertsun02 you can order red clay cored bricks at your local Lowe's and have them delivered to the store for free
this is awesome. have you ever tried to calculate what a heater like that would heat as par as square footage in nominal temperatures? thanks, smashed the like button and subscribed!
If each room of the house had one of these below the floor(modified for fire safety, obviously) and its own fan and vent, all you would have to do would be to connect them together via wiring and into a solar panel. Each room could have its own switch to turn its unit on/off and save energy that way. They make some pretty good attic fans that are inexpensive and don’t take much to run. Sorry, I’m ignorant about all the terminology but it’s just a wild idea how something like this could work
The description says that this consumes 120 watts. If it runs at this rate for an entire hour, you get 120 watt-hours of energy usage. This equals about 410BTU energy output per hour. If a room needs 24BTU/sqft/hr then this is suitable for 17 square feet. Just turn a 100watt lightbulb on honestly
@@joecool4656u answered my question 🎉
@@joecool4656 You smart guys always take the fun out of stuff. Can't use the nifty fan with a bulb smart guy. (Im being funny)
You and Paul Elkins should link up
Maybe whoever owns " low tech magazine " as well
THANK YOU ♥️♥️♥️
forgive my ignorance but is there a way make this AC power instead of DC and would it make sense?
they do sell ac powered ptc elements.
Have you - or someone here - figured out how to add a DC temp controller (in Fahrenheit) to a PTC heating set up (such as this) with 12V Li battery?
I would prefer a temp controller (rather than a DC timer) but the temp control unit I am looking at has 10A upper limit. I believe the PTC units would exceed 10A at outset?
Ideas? Suggestions?
Use a relay to take the amperage. The thermometer only has to apply power to the relay coil (100 milliamps) to turn on the heater elements.
Good Job 👍🕊
thank you! 🙂✔
Can you share links for heating element and fans!?
sure let me look for them. they are all on amazon. by the way amazon sells probably 50 different stove fans so they have lots to choose from. i usually get the elements from bestol. they are on amazon too. here is a link to the elements www.amazon.com/Bestol-Heating-consistant-Temperature-Thermostatic/dp/B07VBDT8NL/ref=pd_rhf_d_se_s_pd_sbs_rvi_sccl_2_1/134-2909720-0136431?pd_rd_w=8NDbx&content-id=amzn1.sym.a089f039-4dde-401a-9041-8b534ae99e65&pf_rd_p=a089f039-4dde-401a-9041-8b534ae99e65&pf_rd_r=5KFZGNW6FGX5X7MV2GWZ&pd_rd_wg=MeUTV&pd_rd_r=5ed2f17f-ba67-4f13-aee1-cc308bc6d230&pd_rd_i=B07VBDT8NL&psc=1
note that ebay sell them too. i've seem 5 for 12 dollars on that site. and i once saw them on aliexpress for 1 dollar each. so search for best price. here is a link to a stove fan www.amazon.com/TOMERSUN-Blades-Powered-Burner-Fireplace/dp/B075F36YNK/ref=sr_1_7?keywords=stove+fan&qid=1698269288&sr=8-7
to see dozens more search for 'stove fans'.
Does not melt the plastic from the heating element when it is on the copper plate.
hi. there's no plastic on them. the wires are 'high temp silicone coated' wires able to handle way over 400F/205C. last time i checked, the manufacturer was listing the wires as good up to 600F! or 315C (so way below the temp of the elements). the hot copper won't get much over 300F/150C so it won't hurt the wires (or any part of the elements). the copper temp itself is self limiting (because the temp of the elements is self-limiting). it's a neat property of ptc heating elements. they never get overly hot.
@@desertsun02 Great i gone test this things thanks.
Very cool ! It makes me wonder if similar tech was used to heat old world buildings before the reset. After all they were brick homes with copper roofs and they pulled electricity from their atmospheric spires.
Source for PTC tablets, fan, and copper plates?
hi. all 3 can be found on big online sites like (amazon, ebay and aliexpress). i generally get everything from amazon when i can, followed by ebay).
Is that an inverter btw the cigarette lighter and battery? If so what kind?
What is a ptc tablet
Nice one, thank you
I would really rather love to use these geat tablets in my cast iron chiminea. Do you know of a way I can hook them up inside along side the upper wall so they will stick ?
hi, yes i do. you can use polyimide tape. i've been using that with these types of heating elements a lot lately and it works great. i have several projects in which i actually attach these types of tablets to a cast iron surface. polyimide tape is a high heat tape. the type i use is rated to 300C (573F) so it works great with ptc elements.
@@desertsun02 I would think that attaching them to cast iron it would everything much hotter than what the heat element rises to correct ? I do Believe the heat will spread out throught the chiminea as much as the heat bulbs cause it to do right ?
It's already hot 70380. My house needs repairs. Moved my things in my runaway camper. I'm going to use it until I get my house repairs. The roaches are the biggest issue. Got a door that is damaged so badly opossums can get in the house. So roaches are impossible to keep out. My place has a street sewer drain in front and it's a roach super highway. You have got to have an airtight place.
In the house it's so bad the ac would freeze up bc it ran so hard. I have 2 AC in there but I need to reset really bad. Just over junkyard the place. I want my place back and I'm going to fix it right.
The runaway is 4'*8' it's tight but you don't use as much energy as a very leaky hose.
My last energy bill was 208 kWh. Winter we have the best utility bill. Summer can cost. Last year the largest bill ever was paid. I'm not doing that again. I plan to use the runaway bc I can turn off the power when I leave. The house I had to run 24/7 bc the ac would never move enough heat out to make turning off worth it.
Living in NYC we had great success with diatomaceous earth, but you need to drywall or something first to close the big gaps.
hi! thank yo ufor the awesome inventions :) i would like to ask if its possible to add ptc heating plate to existing aluminum radiators on my walls, decomissioned since i removed the boiler from my house, can i like fit it behind the aluminium radiator would it heat up the whole radiator ?
Yes fill it with sand
How long could you run it on a 12v car battery ?
How will this perform with only 2 of the PTC elements?
you might be disappointed if you run it with only 2. do know that those fans will run on as little as 2 elements but the heat would be very weak
@@desertsun02Got it! Thanks for sharing your ingenuity. I enjoy your build videos.
I want to hook this up to a 12v battery. I purchased a 12v 7.5a battery but now question whether it is sufficient to power 4 ptc 220c 30a elements. Please advise as I have absolutely no amp/watt education.
My 2nd conundrum, if this battery is sufficient, how do I connect the ptc elements to the F1 battery terminals? I found female F1 connectors at Ace that fit the battery terminals but the hole to attach a wire to won't accommodate the 4 wires of the ptc elements. What size wire is needed to safely connect the battery connector to the ptc wires?
Any assistance would be greatly appreciated.
Now we're talking bro!
That is awesome!
wow, have you thought of making a convection oven, perhaps we could bake some bread at 150 C
hi. I have thought about designing an oven. it may be a future video. just need to work out the details.⭐🙂
How long will the heater elements last if run continuously ?
hi. they are rated to run over 3 years. (24/7). in reality they will probably last 10 or more.
can you connect a wires from a12v solar panel directly to the copperplates and bricks without any converter?
hi. i'm not sure i understand the question. by converter do you mean the heating elements? the unit wouldn't work if you don't use them. you definitely need those.
@@desertsun02 Thank you for answering😀. My wrong! Actually, I ment regulator,not converter as I wrongly wrote...I ment to ask: Can you put the wires directly into the sand battery without a solar regulator 🙂
how do I figure out if this is more efficient that my space heater that heats up oil?
tell us how many watts it is using many amps at what voltage
hi. it's about 120w total power draw. elements vary up and down but they were pulling roughly 2.5 amps each. (30w). i used 12v elements but you can get them in 24v 36v and 48v dc. (check description section for extra info)
WITH EACH VIDEO SHOW EXACTLY HOW THE POWER SOURCE IS CONNECTED....
does it have to be copper ? surely aluminium is just as good?i am going to try this.
i haven't tried aluminum but it would probably work good too 🙂
how far from fan is warmth still felt?..or aproximately how much square foofage will be warm from brick /fan/ptc?
hi. that particular fan pushes noticeably warm air at least 6 to 7 feet. will depend on various other factors too (like the ambient air temp at start up)
If you used more bricks would it increase the temperature, if so by only a few degrees or more?
More bricks mean more thermal mass, or how about 2 of these units next to each other.
How much electricity doew this use?
hi. i'm going by memory but i think it's about 120 watts. (a little more at start-up, but averages around 120 watts after that).
Use some soapstone instead of bricks. Much denser.
i've been meaning to get some of that. seems to be very expensive though. if anyone knows a good inexpensive place to get it, feel free to share link
How many watts are you using.
hi. around 120w. the highest reading was 127. measured with a watt meter
How long will the bricks stay warm for?
hi. they can warm for several hours
HI, any idea about max temp the ptc working?
hi. the max temp i've ever seen these type of elements get to was 470F (that was the 'hot spot' on one of the 12v ones). note that the overall (or average) temp of the element was much lower (maybe 350F). i've seen the higher voltage ones get to over 500F.
@@desertsun02 thank you.
That's a weird looking Sandwich
Hi. I built this and I'm finding the 12v power supply connection is getting very hot. Has anyone else tried this with a similar result? I'm thinking the current being drawn is too great for one power supply.
hi. the connection point on a '12v socket' power supply is not always the best. if the connection point is getting too hot (but not the entire wire) that usually just means the connection is not solid enough at the connection point. a solution to this is to use what's called a switching power supply. they sell some 12v 30a 360w ones on amazon for only about 20 dollars (sometimes less. i got one for 15 once). those are direct wire and they stay cooler than the 12v socket ones. i've been using the switching ones a lot more lately. they are usually about the half the cost of the power supplies with a 12v socket so that is good too.
@@desertsun02 Thanks, I'll look into it. I appreciate the answer.
Way over complicate it but thats what makes it interesting to watch. I would have just taken air compressor intake to the air tank in order to pull the air out of it then use that overly powerful vacuum to get the job done. With a bucket filter inline to keep the junk out of tank. Just off the top of my head thinking. Anyways fun to watch :)
this comment sounds like it was meant for a different video?
Make larger cube of bricks and heat up a big mass to heat house all night?
hi yes!
Can you use a regular brick?
hi. i think so, but i've never tried it. i think i read that clay bricks can handle up to 1000F.
Why is the bottom brick not melting the table top?
hi. i have the bricks up on a metal trivet. it sits low but the brick is up off the table
Any specific cigarette lighter plug in that you plug the male cig lighter into,have tried 2 different ones and they overheat. Is there a certain amperage it needs or something?
hi. plug should be 15 amp minimum (20 amp is probably optimal). unit doesn't pull that much normally but sometimes at (or near) the 'start up' there is a spike. btw - it's awesome that you made it!
Did he mention cigarette plug... where does it get the energy???
@cajunvegan7716 The 12volt plug is in the video, that what the black electrical looking tging is in the video on the table that the wires are connected to. It gets the energy from what its plugged into, wall socket or you can use solar generator.
What do you do when the power goes out😂
hi. since it's a 12v system batteries or solar panels are a couple of options.
@@desertsun02 thanks for the info now I understand more how this works
What is the cost of running this compared to a space heater?
it's hard to compare because most space heaters you buy are AC powered. also will depend on what type of heating element the space heater uses. i have one that uses nichrome wire and that thing is terrible at heating air. the ceramic/aluminum elements seem to do a much better job. btw i have 2 more heater vids coming out very soon. both use ceramic heating technology and run on/off grid. will post soon. maybe this weekend.🙂👍
Are the bricks firebricks or regular old bricks?
hi. they are just regular 'stone' bricks
what is the power unit you plugged into?
i typically use a roypow 15a transformer but a basic 'switching power supply' would work just as good. you can find those for 15 to 20 dollars on amazon.
Каждый элемент после прогрева потребляет 10-20 watts при питании 12 v...можно больше... умножаем на 4 получаем 80 Watts...кирпичам будет тепло...но прогреть помещение не способно...только картонный дом из под холодильника...или большого TV...
How much power does it draw
hi. each element draws about 2 amps on average.
How many watt?
hi. about 120
@@desertsun02 Can it heat the room? Normal elec heating for room is 1500w. Or with a airco heatpump between 300 and 1200w.
@@desertsun02 Do you now the temperature from the air from the propeller? An split airco is 45 Celsius.
Dimensions of brick and sheets thanks
hi. the bricks are the flat stone kind (commonly found at the home stores). dimensions of bricks are 2"x4"x8" (the copper hangs over just a few millimeters on all sides). it was from a batch of irregular shaped pieces i bought online. you can cut it to size with tin snips. it's 24 gauge which is a very common thickness.
I'd be worried about the wires melting.
no need to worry. they are made to handle the heat. (special silicone coating)
but you never showed us how the fan converts heat into electrical for it to run, how does that look?
hi there. make sure to watch the video around the 5:15 mark. i give a quick 'talk through' and show the back of the fan (along with the white TEG chip and motor). it's that chip that generates electricity from the heat that is soaked up through the body of the fan (from the bricks). the bottom of the chip is hot and the top of the chip is much cooler. it's the temperature difference between the top and the bottom that generates the power.
Where you been homie ?
Are you ok health wise?
All out of ideas ?
hi there and thanks for asking. i don't have any new health issues and i've got lots of ideas (so that's all good). the main issue that's been happening over the last few months is that youtube cut my average views and revenue in half (for absolutely no reason) - and ever since then it's been hard for me to scrape together enough money just to buy the stuff i need to make the projects. **i'm going to keep posting though, don't worry about that**. i'm still hoping that it's an 'algorithmic accident' and that they will fix it. (by the way - if you or anyone else has project ideas please feel free to share... i can always use more ideas, and i like designing things that people come up with and want to see built). i think the community 'at large' comes up with better ideas than i do. at the moment i'm working on a video that should be posted in about 2 weeks.
@@desertsun02 you live in the desert right ?
Based on your UA-cam handle and the videos you do outdoors?
Is your heat tolerance pretty good ?
Will this heat my 12,000 sq ft home?
Petiier ?
hi. the ptc elements are different than peltier modules. they look a little similar but are very different thing
Could aluminium suffice?
hi. possibly, but get the copper if you can. it works so good i can't even believe it! even with the fan blowing across the surface of the copper it never went below 300F/150C.(and that was running it for 6 hours straight). the top temp i saw was 320F/160C (without the fan) and a steady 300F/150C with the fan.
aluminium seems to block heat, unlike copper.
@@reddpillAluminium is used in heatsinks as well as copper so no blocking.
Copper has much greater thermal conductive properties which means it absorbs and spreads heat much more evenly and faster than aluminum. That can be easily seen when using copper pots vs aluminum pots in the kitchen.
@@manfredflemme6324 Copper is easier to coat the bottom of pans and most people don't want to eat out of aluminum pots.
are people that ignorents with heat transfer?
A Waffle cooker will do it better.
At what cost though...also, now I long for a waffle.
What is the big deal ? Electric heaters have been around since forever🙄
This uses 8% of the electricity of a 1500w space heater.
I would pay $10 to run a 1500w space heater for 24 hours straight. This set up uses only .80 cents.
@@ericbenko5195 Could be handy for a brass money😅
No it doesn't. A resistive heater is a resistive heater. 1500W is 1500W, whether nichrome or PTC. You don't get any free energy here --- resistive elements are 100% efficient. Your claim makes PTC 800% efficient which is total nonsense.
Well, this is DIY (very easy build) so I can configure my own setup and not buy a Chinese made heater. It is DC powered which means no inverter needed, I can use batteries or solar panels (or panels with a buck converter 20-90-volt input) to run it. Since it is DIY - fixing anything should be easier than the store-bought model.
@@vidznstuff1 You are right but, if I have to convert my DC power to AC power, to run the AC heater - they become less efficient than the DC heater.
