How to make Electric Room Heater 12 Volt DC 

Let the AMPS be with you. Did I see 25 Amps at 12V DC? Your power supply adaptor will contribute to your heating as well. Brilliant!

welldone for not putting stupid background music in this video.

That will make a good Block Heater for my Cummins in the winter time... lol Thanks for sharing...

I used this video, but instead of using an expensive power supply to provide the 12v DC. I simply used a transformer out of an old non working computer power supply, the transformer I use is rated up to around 500w, therefore I just draw around 300w from it and it does the job fine. Obviously the transformer changes high voltage to low, it doesn't turn the power into DC power, but you don't actually need the power to be DC power, using 12v AC is perfectly fine. Therefore the cheapest way to do this is to use a mere transformer, of course I cover my transformer in a kind of half pipe that goes over it, so the 240v side cannot be touched accidentally, so it's safe. Your idea of using the concrete was very good, but I didn't use it as I was worried about it cracking and the element falling out onto the cage area. Therefore I have instead an area cut out at the bottom of the cage, and where two metal rods come upwards and they don't touch the cage, between these metal rods is my element, the rods acts as the positive and negative, the rods are merely mounted on a piece of wood. The cage itself is mounted in a suspended way above the wood, supported by two separate metal rods at the outside that are not electrically connected to anything. And at the back of the cage I placed in an aluminium tray to help reflect the heat forward. I was prior thinking of making a heater using 100w resistors, however you inspired me to make this one from nichrome wire, in seeing how easy it is from your video, I wasn't quite aware of how useful nichrome was until I saw this.

Nice project.Easy to make at low caste, thanks for such items showing.

Well made video, thanks, it's quite amazing what can be achieved with some ingenuity, and curiosity. Nice 1, Thom in Scotland.

SUPER EASY,HELPFUL,REALLY BEAUTIFUL AND GRET JOB,AMAZING MY FRIEND MANY PEOPLE IN COLD WEATHER WILL BE VERY HAPPY TO HAVE ONE!!!!

Great to see construction projects. Not enough guys are capable today or even interested. The fan cannot work as it has no free flow of air. You need to drill some holes at the opposite end. Take care mate. Microwave transformers are incredibly dangerous. 2200v at very high current. Those gloves used with the saw bench were very dangerous.

I saw the eyelets touching each other right after you crimped them on lol. Good thing I kept watching I was gonna say, lol This'll be good.

TOP-NOTCH PRESENTATION! I am totally FIRED UP over this project! STOKED! Seriously, I am eager to check out your other videos. I'm going to subscribe right now. Thank you

SUPER IDEA . POZDRAWIAM .

nice safe design with high temperature resistant materials.

Even I, klutz followed. Means you're good.

I made mine a little different, the cage around the limestone is closed with a mylar sheet and then there are a few holes in the sheet for heat to come through and then I have a huge 5v fan behind the mylar sheet that only gets 3v 200ma and it gently pushes the heat to my feet. Yes I made a foot heater and I also have a 30amp fuse for in case

We can use heater spring at the place of coper wire

Brilliant video thanks from London England 👍

You could have matched the current x resistance = voltage to around 10v ~ 20V (through resistor) where current enough for a small 240V AC fan and put it in series for main current use. For safety, use three pin with Earth (green) connected to the mesh, and put fan to live side and heater at neutral side of series. Hair driers work that way

Great job, a very good video, thank you. Have a nice day.

Çok güzel bir çalışma olmuş

It’s better to take car catalyst mesh ceramics, pull out some material to make less diameter in centre (like bobbin or spools) , wrap this area with nichrome and blow thru mesh with fan

Just a thin piece of steel wire would probably work better. Copper has a really low resistance. You want high resistance for heat. Stainless is a great option. Also use some foil or something reflective so your not losing the infrared heat

Can you maintain a constant temperature or will you need a thermostat?

Looks dangerous ASF, but I will try it🗿

Love that yellow wirestripper

Thanks for this important video

Useful info.thanks.

Iwill use solar charge xontroller to power it and will try to make this heater by this week

Masha Allah Great Work Brother

Nice bhai

Excellent!

BEST WISHES !!!!!!

Excellent

Video bhut achi hai lakin 14 gauge nicrone wire kider sy Millay ga plz tell thanks

Use rock salt instead of plaster material. This will store heat and reduce pressure on power supply

Wonderful good thinking thanks

So what was the reason for making the copper coil at the start?

Can you leave it the whole day? Because it seems not so hot. Just wonder.

Nice project

Thanks. Good information

can I use normal copper instead of 14 SWG ???

gracias !!

Matkap sesinden müzik yapmis :) eline sağlık

Thx buddy . Very impressive

It seems cool and simple enough even for a non mechanical person like myself.. but what is the cost for the components? Because heaters can be had for like 30 or 40 bucks at Target

Ok felicitări

Very nice

Te salut cu respect,tot ce arati tu aici noi in ROMÂNIA am facut din anii1960 pina in anii 1989,asa ca nu te pricepi ,te ai uitat ce consum are , ,,daca eu te as pune sa platesti consumul acela ,l-ai platii???.

That's Awesome

Tu, nu sti sa furi curent,sau tensiune,🤗🤗🤗🤗🤗🤗🤗

Hi! Well, the transformer also picks up power!! That should also be measured.

What would happen if you totally encapsulated the cement and placed in a bigger block for heat storage??? Iquess the question is if I had a 400 watt solar collector and heated up 30 pound block of cement with a hole in it to blow air through I wonder how hot the block would get ins say 8 hours...

What a coool video :) Thank you very much for that input :)

Is that off a grill or kettle

Good job bro

Do you have to use a power supply Or could you hook that up to 12v battery or was the power supply hooked up to 12v battery , By the way live the Video If you have any idea how to make a fan like a box fan ,or something to cool your home I want a battery operated DC fan

It's impressive but after all those hours of making it u still had to get an adaptor and plug it to the power point to get it to work it's the same as getting a normal heater and plugging it to the power point and it heats up in seconds

What is the name and description of the wire used for heating?

Good Job

Very Good

I have been using a space heater that is 1500 watts. My electric bill is around $145 a month. If I make two of these would it still cut down the electricity cost? How much does it cost for that electric gadget with the little fan?Thank you so much for your informative video.

Okay, forgive me for being an idiot on this... Q1: so the wire heats up the concrete, and the concrete radiates the Heat, white ceramic bricks in an old gas/ propane heater.. am I getting this correctly?? Q2: can we not just hook this to the positive and negative on a 12-volt system?

Can the Nichrome wire be (safely) replaced by a Kanthal wire?

I watched this today 12/16/22 and I am very impressed! I do have a few questions though. Where did you get the basket from? Did the basket or the connectors melt? Did the cement crack? Shouldn’t a fan be added somewhere to push the hot air out?

You could make a kiln this way too, couldn't you?

great work

good.

Good sharing

I would love to find something like this, much in a smaller scale.. I would need to heat up to 250 celcius

bide şu sümük çekme işi olmasa idi. sümük çekme sesi yerine müzik olsaidi bence daha iyi olurdu

Like the steam punk look.

If u add a small fen back of this heater than its will b more better

Hmm, how about substituting the plaster with a curved piece of aluminum to reflect the heat out. How would you connect this up to a 300 watt solar panel, battery?

Can you just use a 12V adapter?

Why doesn't the element burn?

Hey ray, i heard that we got a new cleaning machine ...

THANKS YOU FROM VLA.

Amazing

Would this be warm enough to deform/warm a sheet of PETG if placed on top or below?

Doesnt that make the battery short circuit

Nice, would it be possible to have the link for the component used in the video. This could help for the future to manufacture for the interested person it is a suggestion that can be useful 😉

12v * 25a = 300 Watts. Can you build a heater that consumes less than 100 watts?

janab dc amp calculate karke to 25 amp dikha rahe ho smps ki input kitne amp kha rahi 220 volt bijle se smps woh kaha dakar gaye

Which tester is this plx tell me That u used for wire continuity

Nice nice

Great !!! But electricity is very expensive !!!

Lol that power supply alone will heat the room :D

Why did you changed copper wire ? Could it work on solar panel 20 A ? Thanks 😊

is this work on solar

Current = power / voltage. So, 300W / 12V = 25A. Yeah, better have a big battery-array to run that heater for very long.

The last step is to put a U.L. approved sticker on it....

How much heat does it generate?

server PSUs are probably a better heater by themselves

Inefficient but safe. Thanks

14 AWG terlalu besar mas.. pakai 24 AWG bisa langsung membara dengan cepat

what about ampere at the AC level?

You did a great job And very informative video ..well done

Liked

Nice. Wish I could watch without 5 popup trump ads, but it is 2020...

que es lo ultimo que le conectas?

25 Ампер?
