- Video shows how to set up a small Off-Grid 12V Desktop Air Heater! unit is powered using only ONE solar panel. all you need is 2 things to make it... a 100w (12v) solar panel and the heater/fan unit! (sold on amazon for 8 to 10 bucks). great little unit! cranks out the heat! (*115F continuous). *a 12v battery can be used as the power source too (but is not necessary). output temps consistently hover around 115F (+/-5). *measured over several hours. great little unit for personal space heating! one important note: the output temps vary much more widely when using 2 power sources. (one for the fan and another for the heating element). for consistent output temps hook both sets of wires to the same solar panel or battery. the fan and heating element interact with each other only when using the same power source. note that these come in 150W size as well. the link to the 100W heater/fan unit is listed below. *UPDATE: i just posted a double size 100w/200W 12V version of this heater! it's got 2 fans, 2 heater elements is mounted on a stand, has 2 switches for low/high power and it also runs just using solar panel(s) *or 12v battery. here's the link • DIY Solar Electric Air...

So brilliant.Please teach us how to hook up a battery so it will work after the sun goes down.Thank You for sharing Your excellent ideas.
I’d like to set a few of these up in our cabin with 2-3 panels to heat constantly during the day and then run off a battery after it’s dark.
@@613Stuart that's my thoughts, did u ever manage to use these on your cabin?
Exactly my thoughts. 🙏
Hahaha, use batteries!!!!
I wish he'd show how to connect to a 12v battery, too!
Once again you are fantastic!!! Your creative mind is making my RV experience easier and easier. So compact!!! Thank you. 👍🏽👍🏼
This is great I just bought a 100 watt kit with 2 12 v and a 400 inverter and was worried about not having enough power
I got one and I've wired it up to a led PSU, the led PSU gets really hot but the fan sucks the heat away before blowing it thru the heater. It's amazing it heats up my living room no problems and it hardly registers on the electric meter, last year I had a 2000w heater and my bills were outrageous. Ive been trying to find away of controling the temperature, not thermostatically but just a simple power control to turn the power / heat up and down. Thank you for the video aswell🙂 the more people know about it the better as it's things like this that'll save the planet from our over use of energy 🙂
HI Robert, sorry for my ignorane, but do I need a 12v battery between the solar panel and heater? Can's see how to connect heater and solar panel directly!!
@@jeaninehonour4717 you 'll need a solar charge controller
Robert after 2 years can you share more of your experience with this type of heater. Does it work home indoors at winter time when you have snow and 0F outside?
Going to have to use this for my off grid power box I'm making using deep cycle batteries and an old cooler. Cooler can hold the heat in, this can help keep them above freezing so they'll keep working even in cold Canadian winters! genius.
Thumbs Up! Great idea.
I bought and tried it out using my Lithium Generator. The weak point is the fan speed and blades --- not a lot of air movement.
Heating element generates impressive amount of heat for such a small thing.
When I introduced a 4.5V power to the fan, it run a little faster and generated a larger draft but I am afraid the fan may burn out quickly at this rate.
Day time heating may work for a room with an array of these small guys but need to switch to batteries at night. And, winter nights are long.
I guess we can charge the battery-farm during the day and use the the heaters at night, running off from the batteries.
At the same time, we can have other solar panels powering the heaters for daytime use.
Avery good idea but the results are. not encouraging , I believe, with. battery storage with the. size. of solar panels. used domestically. Instead some. kind of ceramic. bricks. of the kind used. in storage heaters might work,,,
Liked, subscribed and went to online Amazon and bought two of these. !:- )
cool! that's great. i've already ordered another one. it's supposed to arrive today by 8!
I apologize because I don't speak English: you can give me the link to Amazón (bbcampo@gmail.com)
@@blasbroto5145 Go to Amazon.com and search for solar electric air heater in the search bar.
Doug van der Hoop
Can you please provide me with the link to purchase this heater?
Thank you
My canopy on vehicle sleeps 2 as is only 2 cubic metres of air space. Perfect to take chill off the area. 200 watts of permanent solar to 105 AH Fullriver deep cycle AGM battery, it also gets alternator charge via a dc to dc charger with solar input. Brilliant little heater for short term use.
I’ve got a space half the volume of yours. How do you find the heater performs?
I have done this it works !! Working on a winter project 👍
I'd like to do use a solar panel, battery and a few of these spaced around my 8'x16' greenhouse. I'm in Colorado so I'm hoping to extend the growing season by a few months.
I have the same interest but live on Cape Cod please PM me to compare.
Did you trying it yet?
I have not but if you get a solar battery, and a ceramic heat lamp, it will help warm up your green house as well.
Did you end up getting one? I'm thinking of 50w is probably more than enough for me.
@@Atemoya26 :there is 3.41 BTUs in a watt. I was given a large solar panel, and figured the best use, without buying batteries, inverters etc, was to use it to heat the house. On a sunny day in winter, it would have kept the furnace off for 6 seconds per day.
This is great! I will be using diy geothermal in my next house and this is a perfect way to get the 60 degree ground temperature up using solar!
Same
No what would be better is getting a heat pump and running that on solar. Heat pumps are WAY more efficient than electric heat so you will get way more heat for the same amount of solar.
You have some great projects! keep up the great work. Really enjoy the stuff you do.
Was looking for something like this to put in my well house so that during the day it will stay warm an or unfreeze. Perfect solution.
nice! i'm glad it helped you
I actually bought this on aliexpress last year before winter. My car stays warm and i no longer need to warm up my car because of the cold!
My, my. As i read these comments i think were all in trouble. Thank you for saving me the trouble of attempting to build this from scratch. I have been thinking of this very project for a long time and never acted upon it and its so simple. I will be adding a 12v 10a inline fuse and a rocker swiatch to power on off when needed. This is just about right for my camping rig that im now using a delta2 with 500w of solar. Heat isnt such an issue with me cuz im a polar bear but id like to pick your brain about cheap low wattage cooling in roughly 250 cubic feet. Any ideas are helpful and appreciated tia. Now to read some of your other posts ✌️
hi. i've got a lot of low wattage DIY air cooler videos on this channel. to quickly find those videos you can go to the playlists area of this channel and scroll through the 'air cooler' playlists. i''ve probably got 40 different designs. feel free to ask any questions about any of them. i see all the comments. as far as heaters are concerned, I've recently posted 2 more DIY air heater videos. here's a link to one. It's a 12vdc 200w DIY Ceramic Air Heater that 'thinks' it's a 500 watt heater (meaning it puts out an amazing amount of heat for its wattage). it should run very well using your 500w system.
th-cam.com/video/iRSG-HWZEEs/w-d-xo.html
OMG! How awesome. It might be the crawlspace heater I’ve been looking for🤔🙂
for a RV to keep the pipes warm?
Just found this and now i know how i can heat my shed for cheap! :D
super great video info and analysis from absolutely the best channel on utube you hit this one out of the park again thank you and keep up the good work
thanks brother! appreciate it.
This is exactly what I was looking for! Thanks
Oh....l love the Tinsel test. Really scientific 😆
Ok so if a 100w panel is used for this heater w/fan, I'm estimating that's a 5-6 amp draw.
The gain would be the (free) heat when the panel or your array has good sun exposure (open canopy). Otherwise you'll need a good battery bank to draw from. This could be a good part time alternate off grid for a cabin, camper/rv instead of relying on a propane furnace, where I can say mine also draws about 5 amps when the blower fan cycles.
this might be a great unit for truck camping or small teardrop camper in use with a power station in conjunction with some type of thermostat to let it cut on and off at certain temps.
Wow, unblievable, super hot... That's all the guy is saying. I'd like to see a real world test of this in a cabin. I bet it would warm the cabin but it'd take quite a while.
You couldn't heat anything with this! Most of the day it wouldn't heat up at all because it isn't matching the panel to the resistance. You have been duped into watching hokum.
Ok, so excellent news! I have another system within the my parents green house that I use, a 1500 watt bucket heater in 15 min intervals on a 24 hour pull pin timer thats pumped with an aqurium pump to a small radiator! So what I did was used the combination of the 2 desk top heaters with one in front of the other and only one fan pushing the air, and the temperature has risen from -1° to 0° rather quick as I was only out there 5 or 10 minutes! So this is a nice way to heat up the air faster, it just can't be used on its own for a greem house in the winter! So I will leave this thread at that! Thats a sucsess! Also I have a temperature/decontamination unit when you enter the green house(enclosed plastic trolley on wheels) I can emagine this should work to preheat the space before entering to get rid of the cold, so it could be excllent for that hopfuly!
Now show us how it would work during the night being it's that time your greenhouse needs the heat!
Very nice and lovely product ❤️
Can you post a link to the solar panel that you used? Thanks so much... really appreciate the video!
Hi So I'm a complete novice at this Sola stuff and frankly elec stuff is a bit weird, But seeing your film and the second on I thought I would have a go. 12v 250w sola panel with controller and 4 little fans hoping to use 2 and have 2 in reserve. It turned up and I read the instructions all 2 minuets, connected it all up and Nothing ??? It wanted a battery ? added bat 12v 180 amp full charge, ran 30 seconds and stop start, removed everything connected sola panel to fan and heater nothing removed heater just fan and it runs. Bat connected to fan and heater runs well. The sola panel was producing 20v in the sun BUT ?? Looking into it a bit more 12v - 100w - 8.333 amps so x 2 fans need 20 amps output from sola panel ? am I right or way of. Andy confused in France
Very nice. Keep up the good work
Currently I have a 180W Panel running to a 80ah deep cycle marine battery with a 3000W inverter. I ordered the same fan and the electric thermostat. Going to see if it will keep my 3 man ice shack warm. We get a lot of sun here during winter too so will be interesting to see how well this works. (Will hopefully be getting some 6V 200ah batteries and wiring in series for 12v) Will post an update in about a week and a half once everything's in and running. I'll be checking to see if the panel is able to run this and keep batter charged during the day.
Did that solar heater work for you?
@@timothyfirth4809 No sadly my battery was way too small to run it consistantly, Would say it needs 200W for the heater and a 50W for the fan
@@MarineFlipper thank you for the reply
@@timothyfirth4809 Would be good for like a small shed or green house tho
Could I add a 12v thermostat controller to this heater fan so I don't fry my greenhouse???
niiice. thank you will be getting one for my campervan with a dedicated portable solar panel so i can save on propane and still be warm enough. im sure it is not powerful enough to heat a whole van.... especially in the dead of winter, but.....on cool mornings or fall or spring when you can stay warm enough with that heater it will work great.
Yes how did it work I'd hate to blow a new solar panel. I'm going to add a fuse. But I would like to know knowledge and confirmation of someone that is actually doing it.
@@hgboone3 i havent bought one yet... i just saw it. but moving to oklahoma soon so its a delayed purchase so i put it on my amazon wish list lol
@@LadyTSurvival yeah thanks well I have a solar panel coming I just wondering if I should just buy the heater. I have no idea why I can't find a DC Electric oil heater radiator type.
I received my unit today yeah. I am going to wire it to a cig plug in that I can plug into a USB that I can plug into my solar generator . It weighs alot more than I thought it is for sure heafty. I will wait to hear from you on how to hook it up or I will continue to watch till I figure it out LOL.. Need what good cheap solar generator you suggest before I buy one. Thank for all your help
need yopur suggestion on buying a cheap solar generator that will power tv, light, poss fridge? HELP
Excellent job❤❤❤❤
That with a 12v temperature relay from ebay and your sorted, wonder how this would heat a shed up
I have doubts... I replicated this setup EXACTLY with nowhere near the temps or fan speed on one panel. I’ve metered the solar panel and it’s generating 100W, not sure if this is real.
Thaks from Spain
If you do the math and take into account the efficiency loss this basically draws 10 amps an hour from a 12 volt battery so if you have a 100 amp hour battery and you want the battery to last a long time you can run this for 5 hours and run the battery down to about 50% assuming you're getting the battery fully charged up during the day when the sun is out and the reason you should only run this for about 5 hours on a 100 amp hour battery is you only want to run the battery down to 50% state of charge much lower than that and the voltage is low enough that this thing would really start to show and wouldn't be putting out nearly as much heat and it would cause the battery to degrade much faster as well.
Alright, heater has arrived! I wish I could easily add a video to show how this is opporating on a slightly different setup! Temperatures are excellent and the only device here I have to measure is an oven thermometer for cooking meat in the oven! Its funny because that works well and the temperature rose almost instantly. Im going to go outside now and bring the setup outside to see if we can heat during the winter off of one heater core
Maybe a person could use a generous soapstone brick pile to absorb some of that heat with. Retain it for a while on a cold day. I'm not really interested in heating every room in the house. A place to keep the plants warm enough to survive with boosted temperatures using indirect heat would be ideal.
Update! Outside temperature -21 or 22 now and inside green house dramaticly dropped to -9! Not a worry! So where it stands its good till -18 outside to have the + digits inside the greenhouse! I will keep going and reach for those double digits
Im going build 4 of those. Heat bill is crazy
I wonder - Solar panels during the day and could I wire the fan/heating element to 12 volt plugs and use a power unit (jackery, etc) at night. I'll be boondocking most of the time in my RV.
hi there. sounds like a good idea 🙂
I was going to suggest a small rechargeable battery but then looked up what a jackery was. Charge up the jackery with solar and run the heater/fan at night. I would think it's about the right size for a small room in an RV.
Well 100w divided by 12V = 8.3A of load. A jackery 500(500wh) would run it for about 5 hours. So for heat during the day, you would need one panel to drive this and one panel to charge the battery for 5 hours of night time use. 100w is 340 BTU, not a lot of heat. A 10’ cube(600 sq/ft of surface) with 2” of foam insulation(R10) no windows and perfectly sealed @70F inside and 30F outside(no wind) will need around 2400BTU/hr (.1btu/sq-ft/degreeF/hr) to maintain 70F inside. Windows, air leakage ect make that number go up considerably. 2400BTU =7 of these, so 7jackery 500’s and 14 panels, oh and thats only for 5 hours of night heat:) there is a reason people heat with wood, gas and oil and not solar to electric. Solar electric heat can be done, but you need to use a heat pump(5 plus times more efficient than direct electric heat).
or a heating blanket on low for 10 hours rougly 20-35ah on high you could do it with 45-55ah.
they have heating blankets with timers that run for 2 hours on then switches off. could use that and wake up when your cold hit it on again
Aww it's so cute
Surfing TH-cam, seen your posting, have a comment: You should try a fish tank heater (adjustable watts) in a old truck radeator with a nice low watt brower motor fan. Just some thoughts.
hi. i have a video of what you describe already posted on the channel 🙂 fish tank heater, low watt fan but i used a transmission cooler type radiator. works good. heat is limited to the temp of fish tank heater though.
I would like to do this for an outdoor cat house.
Did you figure it out? I'm also interested in this use
@James Rohlfing no I didn't unfortunately
Great example. Do you have any examples where a thermostat and timer have been used to control temperature and also when the heater comes on?
hi there. i haven't added thermostat or timer but it would be easy to do. i'll look into adding one
Please let me know how that works out
I was thinking about using something like this combined with a clay pot to warm a small room in case of power outage...
I'm living in my astro. No charger to charge my phone, and no heater,.its very cold here,I need help with one of these, I need a larger heater for the van.please show me the expenses but I need it to run continually. Unless I'm out of the van.
How about insulating that brick and using the fan to heat it during the day, then removing the insulation for evening heat?
Run a copper pipe through the centre of a barrel filled with liquid exhausting upward. Air passes through the water container and retains and gives off radiant heat.. wonder what kind of liquid would be best? Cheers
Glycol sounds like a great solution to your idea! Like automobile radiator antifreeze. It has corrosion protection in the liquid to protect your pipe and barrel. and it resist freezing and would be ideal for temp fluctuations. Great idea 💡🙂
On second thought! A copper pipe inside a larger diameter copper pipe and the void between the two pipes filled with glycol and the center of the small pipe is the air vent. The radiator can be in the shape of a Gatling gun or revolver barrel with the heater placed behind the tubes the heated forced air passes through the pipes heating the glycol filled copper! I just might try this🤔
holly cow , 340 btus of heat!
Just for a sense of scale 340 Btu is the energy it takes to raise 10 gal of water 4.8° F in one hour (or raise 1 gal by 40.76° F). A Btu is is based on water and the Fahrenheit scale. 1 Btu is the energy it takes to raise the temperature of 1 pound of water, 1 degree Fahrenheit in one hour. 1 gal of water is 8.34 pounds.
Nice Video thank you 😀
Sometimes you were showing the temperature in your Shadow and it was difficult to read. And the video was pretty long. But kudos to the heater it looks like it works great. Thank you for sharing
May you try using a blow dryer with the 100 or 200watt solar panel to check if the blow dryer will power on.Wal-Mart has them mini heaters that's only 250watts ???
a well insulated van can be heated with 500w, 5 of those $10 heaters... job done. although you wouldnt want to run a long time because, well, batteries... but if you have more solar watts than heater watts then you can run it as long as the sun shines. free heat..
Hi can you please post link for heater and solar panel please.
I like to buy one set .You did good job.
Thank you
hi. links are in the description 🙂
Interesting..good application (my chicken coop)..however if i were to use this for that, i would have to calculate how many 12v batteries would i need to run it at night, and how many panels to recharge those batteries..
You could set this on the dash of your car and the windows would never freeze in the winter.
very interested in making one of these could you provide instruction on how to wire it up thank you
hi there. all the wires come pre-attached to the unit. all you do is twist the red wires (positive wires) to the red or positive wires of the solar panel (and then connect the black (or negative wires) of the unit to the black or negative wires from the solar panel. btw it doesn't matter whether you connect the red ones first or the black ones first
@@desertsun02 thank you have
@@desertsun02 sorry one more question were does the fan wire go to the 100-watt panel.
yep. you put the heater wires to the 100w solar panel and the fan wires to the 100w solar panel (near the end of the video you can see both sets of wires connected to the solar panel wire
Thanks Great video ! At the moment where I live the daytime ambient temperature is 10C 50F what is it where you live ?
hi. it's highs in the 60's (F) - mid 50's at night
what is the performance on a cloudy day?
Does it work at all?
hi. it would depend on the type of solar panel you use and how thick the clouds are. amorphous solar panels work the best (by far) in cloudy conditions (monocrystalline is a distant second). monocrystalline and polycrystalline work okay if it's an "even" cloudiness and the clouds are not too thick. as long as the panel isn't shaded but it's getting indirect sunlight they can work okay. if it's spotty clouds and the panel is partially shaded then mono and poly don't work well at all. the only panel good if it's in partial shade is amorphous. it might sound confusing - for a better explanation i've got a video on this.
Do you know how many DC amps the little heater drawls. Very interested in getting some of these to work with my solar. Any additional info would be great, thank you 👍
hi there. honestly i'm not sure on the amps. i'll have lots of extra info in my next video (which will be out in a few days...maybe even tommorrow🙂). in it i show a 200W DIY Air Heater made with 2 of these. that set-up has dual speeds/heat settings with 2 power switches and it's all mounted on a homemade "slanted" stand. take a look at it. it may be what you're looking for.
@@desertsun02 I will certainly do that 👍 thank you
hey there. it's posted! here the link th-cam.com/video/9559yVp9koU/w-d-xo.html
100W/12V = ? You do the math! I already know the answer.
It's simple math really. A 100w heater will pull 8.3 amps @12v or 4.15amps at 24v.
so when the sun is shining you can make it even hotter?
Love it.
I want this. How do I do?
Nice video! What is the current draw for fan alone? Heater alone? The positive lead splits into two wires. Are there two separate heating elements making a low (1 element) and high (2 elements) possible? What is the current draw for each? Variations in fan speed are likely slower when current is being drawn by heating elements-higher when not.
hi. i don't know the exact breakdown of the current for element and fan (but i can tell you the fan uses almost no electricity at all, just a very small amount). i'd guess the fan only draws 0.05a to 0.06a (50ma to maybe 60ma).
Lmao! Updating a thread again! Thanks for no back lash from the excess comment threads! People here must actualy appreate feed back! So thiers still possible hope for the heater setup! After inspecting the green house further I noticed all sorts of outside exposure because I could see the light from the outside of the green house from working in there at a slightly different time of day! So feed back is good! The environment within there was not completly sealed! So 2 cans of spray foam where added around the perimeter and that should change the information alot for efficency! The ceader shims where lifting the frame in some areas
Enough heat to warm a 200 sq ft greenhouse in 0 to 9f degree winter?
Hi, thank you so much for posting this. I just have a few questions. I am living in a small SUV and last night it dropped to a chilly 20F. Anyways, I would like to use this for two purposes, 1) keep my bananas (and other food) from freezing during the day, 2) possibly keeping myself warm at night. My set up is:100W solar panel connected to MPPT morningstar controller and my car battery. When the weather is warmer, I usually power my 17L Engel fridge with the set up (direct line to battery - 8 gauge wires) - haven't had a problem for the past 2 years with this. I'm thinking in this winter to switch it so that I connect the heater direct to the battery (with a cut off switch if battery drops below 11.5V). Any thoughts? Also, it says there's a "safety" on the heater, does this mean that if it falls over it will shut off? Thanks for all your help!
I am sorry no one took the time to answer you back. Yes, it should work just fine, and yes it means that if it falls over it will shut off. If you have the means, you should invest in a good marine battery to attach to the solar panel, that would hold a charge much longer.
OK, got the fan going, but the element is not getting hot!! What do I do??
hi. the main reason i can think of that it might not be heating is that it's not getting enough amps. it needs about 6 for it to work the best. also make sure the connections are solid. if it's all connected properly and you have a good power source then it could be a faulty heater (but that is unlikely)
How do you hook it to 2 solar panels if there is only one set of wires for one solar panel?
I just ordered the heater, I have the panel and going to wire it directly to battery for heat at night, panel should charge battery during the day.
sounds good 👍🙂
This is the best option
3:25 Could you do another in depth video on how you do the wiring connections...
sure. what part are you confused on? note that the wires to the heater and fan are pre-attached, so i basically just connected them straight to the solar panel.
How can I hook up a solar panel to a heating pad for cats or heater in cold months???
Hi Only recently our boiler stopped working. I want to make a powerpack for this type of car cigarette lighter fan heater. I thought 2 or 4 9 volt batteries connected both in series and in parralel to make 18v would work? What do you think? I plan to use rechargable 9v batteries.

@@desertsun02 damn dude you are on top of your game ! Thank you very much! Subbed definitely!
@Fat Lives Matter yw and thanks for subbing!
Thanks for the video. But how did it get to 350 degrees f. And than u ran it for about 4 hours n it stayed at 105?
How would you add a 12v battery to charge when there is daylight, and power the heater when it is dark?
You would need a solar charge controller this will have an input solar panel and output to the battery and an output for your devices
It'll have the brains inside the circuitry to be able to handle the process of putting the power where it needs to go
You connect the solar panel to the charge controller and then the device output to your heater when you want to use a battery you connect the battery to the battery port on the charge controller
Keep in mind even a small heater needs a surprise me large amount of electricity when it comes to batteries for example you would need pretty much a 12 volt 100 amp hour battery in order to run that heater overnight and that might not be enough to run it overnight you might need like 120 amp hours but 100 amp hours might do it if you get good sunlight
That's a $350 battery for that one single hundred watt heater and you need another one of those $350 batteries for each heater you add
Solar also becomes a problem 100 watt panel will no longer be sufficient you would now need about a 300 watt panel because you need enough power to continue to run the heater and as well as enough excess power to fully recharge that battery before nightfall again you might even need closer to a 400 watt panel since you're probably only going to get 200 watts out of it you'll be spending a hundred of that running the heater so you'll have a hundred going into the battery now that I think about it that's not enough because you're probably only going to get about 8 hours of real power and you have 1200 watts that you need to put back into that battery so you probably need two 300 watt panels the further south you are the more sunlight you get the less panel you would need but you would need to get a realized 300 watts reliably out of your solar in order to both run the heater and recharge the battery fully per day so that the battery can run the heater overnight
It is doable it's just not very cost-effective this is why most off-grid people do not use solar for heat
The reason what he is doing work so well is because he's not trying to run it overnight solar panel directly to heater and just run for whatever you can during daylight hours that you could do pretty cheaply
@@nerys71 Thanks for the info. Much appreciated.
Looks good What make was the plan as there’s lots of Chinese copies out there
Thanks...
you're very welcome
Have brought my little heater and solar panel, but can't work out how to connect the two!! (sorry real novice!) The solar panel has an inverter connect to it, so where do i connect the wires from the little heater to?? Have red and black connectors coming from inverter for battery connection.
I wonder if t will heat a greenhouse
No not even close but it will keep it a little bit warmer and of course depending on how big your greenhouse is if you're talking one of those little 6 ft x 3 ft micro greenhouses this might raise it 10 or 15° depending on how cold it is
Hi great video can you please tell me how many Amp's it uses
thanks! it uses about 6 amps
wonder how much battery needed to run all night?
This would only heat around the desk area right? Maybe a bathroom but not a room.
hi. i generally use it for a personal space heater. can heat a small room, but you might need a few for a good sized room
@@desertsun02 ok, thanks!
hey desertsun. Great video. Whats your thoughts on this set up vs a solar air heater? I mean what do you think is better to heat a small room?
hi there. that's a good question. i could write a 'whole book' on thoughts about those questions, but to keep it brief, a lot depends on your situation. the solar 'thermal' air heaters (aluminum can ones as an example) are bigger and often fixed to the side of a house, so you have to decide if you want to go that route. using a system like the one shown in this video offers potentially more movability (you can move around the heater and solar panel easier). also, the hot air that is generated is generated on the inside of the room or structure (not the outside like the solar thermal air heaters) so you don't have to find a way to pipe it in. on the other hand the solar "thermal" air heaters are probably more 'efficient' and can also be made to be 'semi-portable' (most of mine are) so they both have advantages. i've got like 4 or 5 different solar thermal air heater vids if you wanna see more about them. i've also got at least 2 more air heater vids coming out this season (fall of 2020).
@@desertsun02 Thanks for your awesome reply. Good information :). Its all very interesting. I have insane heating bills and my lounge and kitchen faces east to south east. Any ideas which of your two heaters would be a good preference to help heat a 42sqm about 452.sqf? let me know :)
@@desertsun02 i was going to try to make one of this heaters with soda cans or drain pipes in the box thing. But it's outside. What happens when the sun leaves? What if it's 10° here in NJ at sundown. Won't the cans get freezing? I hate the cold. I would not be happy if the cans froze and gave me air conditioning in the winter.
Hey Bro, been watching a long time. With you being down there in AZ with all the sun, can you make a solar hot water collector and a radiator with an electric fan for us? I want to make one for my garage here in Montana but I dont think I get the sun you get.
Thankfully we in Montana get more sun during winter than the North East👍
Great job. I write you an email last week and am having a difficult time wiring the tabs up. I sent a pair back and I just got the other 2 in nail and I can’t get the heating to work, just fan. I think I am not wiring correctly
do you have any idea how you would connect this to a battery bank using only a single plug in?
I love your video here. I went out and order a solar panel and the same heater. What I am not sure is how you hooked the wires together. Did you strip the adapters off the solar panel wires?
hi there. nope, i didn't alter the solar panel wires in any way. i just buy 2 wires that have mc4 connectors on one end and bare wire or ringlets on the other end.
Do you have a BTU rating of this fan under full power?
It's that a fat screen monitor?
Would this work fairly close to plants in. A 10x20 green house that will be insulated. Plants would be about 2' -3' away
hi. sounds like a good idea. i think it would work good
Did you hook it straight off 12v solar panel or thru a regulator? Just curious. Panel usually puts out up to 19v, do you think this heater can handle the extra voltage?
hi. it's just a straight connect. yeah, it handles it fine. it's just a little extra "push" behind the current. it would have to be over roughly 30v for it to have any negative effect. (the only things that need exact voltage are things with sensitive electronics in them - then you use a regulated power supply). interesting side note... i actually own store-bought 12v power supplies that put out 17 volts. they make the "non regulated ones" that way on purpose (usually 14 to 17 volt output for running 12v items).
@@desertsun02 Thanks, I will buy one of those to try. I have a 100w solar panel setup that I use to run a fan during the day on summer time. I will just switch the connection on winter time to help give a little heat up a small area.
Can I add a 12v thermostat controller to this heater? So I don't fry my greenhouse
hi yes.
I'd say that it's putting out about 100 watts.
how about hooking it up to a radiant floor mat (winter hot house project) thanks!
hi. i've been looking into some of the radiant mats. it may be a project in the future
Can u hook this up to a out side dog house??? If anyone can answer
i think that would be a great idea.
They don't communicate the voltage affects both of them so if they have the same it changes them together
So I set the heater one infront of the other like I said within the comment below, and to my hand it feels like double the heat because it preheated before entering the second heater core! I will time this for another hour! Leave another comment and call this a night after leaving the temperature readings here!
Hi. If you would like to use just one panel or a solar generator, how would you connect the wires? I saw there are more than two wires. Sorry if it is a silly question, but I am not sure about that. Thank you!
By the way. Can I connect this directly with a socket to a solar generator?
hi. yes you should be able to connect this directly to any 12v power socket (any one that handles 100w or more). you just need to use a 12v plug that can handle the amps. to answer your other question; the wires are all either red or black (positive or negative). it's a pretty easy connection... you just hook all the read ones together and all the black ones together
@@desertsun02 Thank you so much for your help!!
I would like to mount one of these below each window which I have attached a solar panel to. What is a suitable heatproof material for mounting on the wall and screwing the fan heater to?
Will this heat up a small room ?
What does one of those cost? I need the materials list as well. Thanks for the video! It looks like what I need for my greenhouse.
hi. some sellers overprice them these days but you can still get them for about $16.00. here's a link to one www.amazon.com/Maxmartt-Constant-Temperature-Humidifier-Conditioner/dp/B081111YTQ/ref=sr_1_54?crid=1B8W3MV29Y1I&keywords=12v+ptc+heater&qid=1642632518&sprefix=12v+ptc+%2Caps%2C1004&sr=8-54
