- video shows how to turn an Ice Chest into a 12v off-grid Hot Water Heater w/12 gallon storage tank! only 5 items needed... an ice chest, a DC water heating element, a universal adapter kit (for the heating element), a tube of 100% silicone caulk and teflon tape and that's it!. you can get the dc water heating elements and the adapter kit (flange) from amazon. ice chest is from home depot. super easy build. full instructions in the video on how to build it. i show several timed temp tests using different volumes of water in the video but the short of it is you can heat 2.5 to 3 gallons (enough to fill kitchen sink for dishes, laundry, cleaning etc.) to 120F (50C) in about an hour (and up to 140F/60C in about 2). i've also included tests showing how to heat 6-7 gallons to around 100F (37.7C) for taking a hot shower. i'll post a link to my vid. on how to make the 12v off-grid pvc shower assembly below. note: use the lid. earlier tests (not shown in the video) confirm that it takes 50% longer or more to reach same temps if you don't use it. note on the water temps: there was typically a 10 degree difference between the hottest water in the tank (nearest the element) and the coolest (farthest from the element) if not stirred. when water was stirred it averaged in the middle. water was stirred during shower water test so the temp difference was only 2 or 3 degrees. tips: apply the silicone caulk very liberally and make sure to let it dry the full 24hrs before screwing in the heating element. use a good amount of teflon tape on the threads of the heating element. i went around at least twice. i decided not to use the screws because the silicone caulk is more than strong enough to hold the element. also there's no need to add extra potential leak points. all in all it worked out great! and absolutely no leaks. had a paper towel under the flange during all the tests and not a drop. works on any 12v dc source that puts out about 12 amps. three ways to run it: Two 100w solar panels *directly hooked to the heating element, one or more 12v deep cycle batts or a transformer that puts out 12v. if you want to run it on solar and you want to use the off grid shower, just add another 30 - 50 watts for the 12v bilge pump. 250w of panels would cover it with ease. also note that i used a 150W DC water heating element but if you want to use a 300W or 600W DC one it should work. just make sure it has 1" NPT threads so it fits the flange. if you like the video please rate sub (click bell) and share.

I came across this in early 2023 and built one for my cabin. I added a 12V thermostat to keep the water at 101F. I am currently building the shower using a 500 gpm bilge pump as outlined in one of your other vids. I repurposed a Harbor Freight 100W solar kit charging a 100amh battery to power my shower and outdoor washing station. I also followed your design to make a 5-gallon bucket cooler for my cabin. I'll see how it works this summer. Thanks for the great ideas.
hi. i'm glad the projects are helping you! sounds like they are working out well. 🙂
Sure would like to have a link for that 12v thermostat, drives my 75yo brain nuts trying to find these things. Thanks either way.
I made one of these out of a 5 gallon Colman water tank. Works great, takes a bit to heat up, but once you're there hot water all day.
sweet!
Dead simple, love it. Although I would go with a higher wattage element.
hi and thank you! yes, indeed. they sell 300w and 600w 12v DC elements also. either should work good
Exactly what i planed to build. I bought camping shower already.😊 A very nice and informative chanel. So happy to have found it !
hey there, i'm glad you like it! 🙂
Great vid. Quick question on projecting time it would take a 10 gallon water heater to go from room temp of 70s to a 100 degree shower: It would stand to reason that since you found 6-8 min 6-8 gallon shower a 2 hour warm up affair that a 10 gallon setup would surpass the 2 hour mark by a bit but maybe not by an entire hour. In a real world application where not everyone would want to wait 2 hours for a hot shower, what are your thoughts on bumping up from the 150W water heater element to a 300W? Maybe more like an hour-ish to get a 10 gallon tank to temp? You end up using 24 Amps in that hour....within the capacity of a standard deep cycle battery. A single 100W solar panel shouldn't have too much trouble recovering from that hit with an approx 30 amps/day collection rate. So running some rough projections...2 panels would roughly equal two 10 minute showers with a 1 GPM showerhead and a 10 gallon tank. And those 2 showers would have to be staggered about an hour apart. So if one person tends to be up and shower before the other this could work pretty well. Could push the envelope a little with that 2nd shower still pulling off the same deep cycle battery but 48 Amps for 2 showers puts many 81-100AH deep cycle batteries in the 50% territory. I guess the hope is the morning rays start charging the panel by the 1st shower and before/during the 2nd shower. Obviously a 2nd battery run parallel would be a safer/smarter bet for the cloudy days. Feel like I typed a bit more than I thought I would but figured being more specific with the question and scenarios helps paint a clear picture. Maybe a little thicker wiring since you are pushing 24 amps with the 300W setup vs the 150W 12 amp setup you are using.
DESERT SUN 02 You never cease to amaze Me but I admit Im a geek Who's obsessed with solar gadgetry.
Excellent idea! Maybe some day I'll try something like that using a 12v car immersible beverage warmer.
You could almost use this for radiant heat in a camper van with some water line and pump diy. Perhaps not up to high temps inside, but not freezing.
good idea 👍
Ironically this rabbit hole of mine led me here while trying to fab a diy in floor heating system for my tiny ambulance home
Awesome video! Thank you 🙏 However, I'm having trouble finding the items needed on Amazon (probably because I'm not using the correct terminology). Links and/or pictures of packaging for the flange and heating element (like you did for the ice chest) would have been very helpful.
Also, I'm not clear how to attach to the power source.
hi and thank you! amazon still has both the flange and the element. the flange is a camco 7223. here's the link www.amazon.com/Camco-7223-Universal-Adapter-Kit/dp/B000BQMK9C/ref=sr_1_1?keywords=camco+7223&qid=1699378523&sr=8-1
the heating element is a 150w dernord heating element. here's the link for that www.amazon.com/Dernord-Immersion-Submersible-Element-Stainless/dp/B0761L2Q8M/ref=sr_1_9?crid=3342738J8LHOY&keywords=dernord+150w+element&qid=1699378616&sprefix=dernord+150w+element%2Caps%2C177&sr=8-9
it's just a straight connect to connect it to the power source. positive to positive and negative to negative.
Thanks for making this excellent video so short and informative! Great idea and great presentation. THANK YOU!
you're welcome! i'm glad you liked it. ✔😎
Keep it filled with a Kerick valve and hold the temperature at wished level with a XH-W3001 thermostat module.
Would you happen to know a 25amp thermostat similar for a 300w heating element?

Great video, I'm trying to make hot water using compost to heat my biogas digester.
Several years ago i probed my mates muck heap, only because i happened to have a temperature probe in my car. I was suprised to find the temperature inside the heap, about a foot in, was just shy of 60°C. This is above legionella bacteria temperature and last I heard he was looking at ways to heat up a water tank in his small horse shed.
I would like to know the starting temperature of the cold water, right before switching the heating element on..
PLEASE DO A COMPARISON BETWEEN THE AC WATER HEATING ELEMENT WHICH YOU FEATURED RECENTLY AND THIS DC ONE. IM CONSIDERING INVESTING IN SOME .IM DYING TO KNOW WHICH IS BETTER.I CANT AFFORD EXPERIMENTS GONE BAD AT THIS POINT.THANK YOU FOR TESTING SOLAR STUFF SO WE DONT HAVE TO .I REALLY GET A KICK OUT OF YOUR PROJECTS.EXCUSE MY WACKED All CAPS KEYBOARD.

I think i am going to use your fabulous idea and incorporate it into a DIY shower. Im hoping that 480w of solar can give me hot showers every few days in winter without underchanging my battery. Thanks so much for taking the time to upload and share your ideas. :D
you bet! this works great for shower. 😎
I am going to use this same concept for a in floor radiant heat system. My concept is using large electric water heater and swtich out the elements for higher wattage elements. Run the right amount of panels to the elements and then using a DC boiler pump with direct connection to solar. This will allow the pump to kick on in the early morning hours and then the heat elements to draw as much energy as it can heating the water up as the whole day goes. This should provide more than enough heat during the day and still be pretty warm at night. This is not going to be the main heat source just additional heat.
I have not seen anyone do anything like this in their builds. Though I have seen some where they loop the pex under their wood floors then put aluminum foil ( towards the floor and pipe )backed foam between the joist using scraps of wood then insulate it with fiberglass and then stapled up house wrap. This allowed that floor to heat up and produce some heat for the place. If I recall the person did this with a combination of hot water panels, wood boiler stove, and DC heat with water heater.
I would buy a water tank that was set up with DC connections and works with a solar array voltage of 600v up to 10kwh. Built in thermostat and a water tank volume of 20 to 100 gallons. This would not only work for my project it would also work in any home by adding a pre heat water heater.
this will work, and will be VERY reliable. That said, you would get about 3 times as much heat output using the same amount of power with a good mini split heat pump. I have an Innovair unit that works AMAZINGLY on my solar system. At most it pulls 1200 watts, and heats about 800 square feet for me in the south where it doesn't get too cold. Also handles the air conditioning just as well even when it's 105 degrees out! Too bad it's not on the market anymore. Has a very high SEER rating. 30 if I remember correctly.
I do NOT know much about the premade heat pump water heaters, but for the price they are charging for them, they had better be good! Give one a shot, make a video, and post it for us to see?
I am using a pre-heat water heater as a dump load in my system already and it works great to soak up the extra power when the batteries are full, but let me tell you, it soaks up GOBS of power, and heats the water VERY slowly!
@@sbartasek We are now looking at just buying a full on solar system hybrid type that sells back the energy that we do not use or what we do not use to charge the battery bank.
Heat/cooling I think will be done via a heat pump. Full size unit with traditional hvac system with hepa filters and pre filters. We like the idea of having several mini splits, one per room which would account for 8 units. Though the only thing that I do not like about the mini splits is their filter systems and the fact that we are going to have to pull them apart and clean them from time to time. If we just install a full on heat pump we can pre filter them in each room and then hepa filter tham at the unit. (pre filter means that the returns will have filters at each of the 8 returns) When we build we are still going to put in 8 zones of pex tubing because it is super cheap to do at the time of building. I also am still looking in to electric flooring as well. Though the one major thing about those are the cost of the electric flooring. The price per foot is expensive and with out knowing anything about them. Some of the instructions talk about every 3 to 6 inches. Imagine a grid of them over 3000 square feet is going to be quite a lot. 12000 to 6000 liner feet to be exact. Then they spec around 10 watts per foot. We are talking 120kwh to 60kwh peak loads. This is why its disconcering when looking at electric flooring.
Deye is a company that makes mini splits that allow direct connections to solar. They have a built in mppt controller. The company also offers a water heater in the same style. The specs state something along 3kwh max solar while I have seen videos where people are putting only 1kwh or less on them. Though I still wonder how they will work when the sun is super low and its in the dead of winter.
Which is why we are 100% now considering just going with a solar system with grid connection. We are not going to do net metering and opt to sell back to the grid instead. The net metering would be nice if we were going with just grid tied solar. Yet we want to be "off grid" and to not rely on the grid for power. While we have not gone with out power for more than several hours we fear there may be a time in which the power can go down for several days.
We are lucky to have natural gas, yet the price of said gas is becoming costly to keep it going for heat. While we use it right now for cooking, water heating and heating we would like to reduce it down to some cooking and switch to electric on almost everything else. I have switched out my gas griddle and char grill for an electric 24 inch griddle and a 8x14 pannini grill. So far things have work out pretty good on that end. Out cook stove is natural gas and in the future would like to install a double electric oven while still keeping the range intact. We also plan on doing a induction or electric cook top. To do induction we would have to really consider an expensive swap of our cookware. Of the 3 newest saucier pans we got they are induction ready. Yet I was thinking about swaping out my entire cookware set and buying a new set which runs around 1000 dollars. Induction ready runs about 2300.
Anyways I have some options and need to do some more reasearch. I have even thought about the well type heat pumps as well.

Just watched a vid to convert a metal tank water heater from 120 volt to 12 volt.
This is WAY CHEAPER ❤
And I am known to be that . . . As in cheap😅
I love the idea now I need to make it with an on/off switch and plumb it into my shower and sinks
this man is a genius
You have to fill it to the top and see how long
Hey there's a smart guy ty I been thinking of adding it to pvc tanks
Very good. I done a similar thing with a steel 230v 20l water urn. Added a 12v 100w & 12v 600w element. 600w heats 15l to 30deg in 15 mins for showering (no cold mix).100w to heat water up slower but lower wattage (never used). Added a probe & wired it up to thermostat for regulated temperature. Added a round bowl with sink hole inside 3/4 way up to act as a baffle. External self priming pump added to push water to sink or shower. External cold water tank under van pumps water to water urn if needed. Urn has original water gauge to show how full. Finished it off by added insulating jacket (silver floor insulation) Cooler chest is simplier to make. This fits under sink unit & installed in my van conversion. Container holds heat for hours as insulated. No leakage either in transit. Cooler chest is a simplier solution & a great idea. Originally I was going to use a 20l metal new petrol container. Problem was fuel container has to be stainless steel. My set up is 200w solar panel with 12v 220amp battery. Cool chest does not corrode which is a good choice. Well done great video.
Jason, can you please provide the product name / info for the 12v 100w element? Also, what did you use for your temperature controller/thermostat?
Hi, just looked on eBay item descriptions at pricing to UK are:
Temperature controller: Ebay description: 12/24V Digital LED Temperature Controller Switch Probe 10A Thermostat Control £4.59 + 42p postage
Water heater: eBay description: Water heater, cartridge heater 12v 100w, 1/2" bsp, antifreeze, animal troughs £26 including postage.I bought this in error ordering a 100w instead of 600w but still installed it anyway.
Regards Jas.
@@jasonannesley5889 Jason, for your van, how do you stabilize the element while driving? I'm considering installing an element in a water tank in my van, where I would screw it into a bulkhead flange or similar, but I'm afraid it will bounce like crazy while driving, ultimately loosening the seal, or having the hot metal element bouncing on the side of the plastic water tank. It seems like the 7 inch element would have a lot of torque on the flange when it bounces ...Thoughts?
Hi, the heater element has a 1/2 BSP thread. I put a 1/2 BSP nut on the inside of the water tank I placed it in. I also used waterproof high temperature sealant around threads to make it 100% leak proof & left it to set 24hr. The knack when installing it in your project is don't install the element too close to the bottom of the tank (so element doesn't touch bottom & melt tank). Place element like guy has in video. Drill a hole in the tank so the element fits tight with no play. For gauging drill bit, drill in a off cut piece off wood. If element sits snug in hole you are using the correct drill bit. Only use tank for heating when water is in tank covering element. Never switch on with tank empty. Element can get extremely hot & burn out. As mentioned in my original comment I made my heater from a stainless steel water urn. My water tank sits under my sink cupboard on a flat surface. For added security there are 2 bungy cords strapped around it for added safety. The cupboard holds a 25l cold water tank & a 15l waste tank for sink. As they are all tightly packed in cupboard with doors secured with baby locks I have had no issues with water leaks or movement. All I would say is test everything before installing it. Regarding your tank you can strap it down with straps or use metal banding to secure it or if it has mounting holes uses these. It may be worth putting some padding underneath tank to reduce vibration. Padded insulation, even old piece of carpet etc. Regards Jas.
I have a 500w solar panel and wind turbine kit from Amazon, as yet unused, in light of the power companies ripping us off i am looking for a low voltage method to heat water for shower use or general use. I think more equipment will enter the market based on this to enable consumets to rely less and less on the grip and more importantly stop getting ripped of.
I would like to see your system rigged up to an off grid set up with actual power usage and time records shown.
Most awesomely simplistick..well done!!!!
Wow! Thank you.
you bet! i'm glad you like it. 🙂
Great way to use at camping but..2 hours to heat a few gallons? will you make one with more elements to heat the water faster?
Unfortunately that is the down side of low voltage water heating. The higher the wattage of a heater the more current drain on the battery and cable size required.
I do think tho in light of energy prices rising it won't be long before larger 12v elements are manufactured.
so about 1 degree per minute off of a 12 volt battery in 2.5 gallons of water? so maybe half that time that in half the water?
Always something interesting to see here. Thanks
Isn't that the truth!
Brilliant video
Is there a way we could make a water heater for showers from 5v portable battery devices? That would be amazing. Wouldn't have to be super hot, just warm enough to stand in.
Look for USB powered fish tank heaters. There are a few and they should heat about a gallon of water to 90 plus F.
@@dannynova3412 thanks for sharing that great information
Let me see, working all day in the field, would love a shower just now, ok i am not working in the field, but off grid, 2 hours, then have a shower, brilliant
excellent video, options to change elements for faster heating and all instructions, well done, regards, jeff.
Would I be able to Take a standard 6-gallon Rv propane/electric hot water tank that runs off 110-120V and change the element to 12V DC? I can't see any flaw in my thoughts but I believe you probably thought about this way more than I. :)... Hmmm I guess i would have to attach a Temperature shut power off sensor on it. Perhaps take a sensor to the outside of the metal and have the power go through the controller...
I am definitely doing this
Just to brilliant guy!! Thanks.
Brilliant, truly brilliant.
thanks! 😎
Great write up and design. Cool system... or I'm better to say hot system.
Wonder if this could work for a Water tank mounted under My sprinter van hooked up to a toggle switch so my water doesn’t freeze in the winter and then I also could turn it off when it’s not needed so power isn’t being wasted during the summer time.
A Hot shower during the Apocalypse? = GENIUS.!!
Thanks ! What size cable with the crocodile clips on ? As in, if using from a 12v battery to the element terminals.
That would also need a 15amp fuse on the live from the battery to the heater terminal.
hi. i used 12 gauge cable (but 14 should work too). 16 might be a little too small
Also use one as a dump load if you are off grid with a wind turbine that is in conjunction with solar
Was thinking of somthing like this for heating in a van conversion. Most have large tanks of water if its steadily being warmed by the batterys/solar should provide a sort of central heating effect..
hi. sounds like a very good use for this 🙂👍
@@desertsun02 How can the element be stabilized in a water tank while bouncing down the road? A bulkhead flange seems inadequate to stop the element from bouncing and torquing the seal loose or breaking the element itself while driving... thoughts? Maybe the element could be secured against the water tank at the end of the element? using a material that can handle the heat?
where do i buy a 12 volt 150 watt element... Please give Link..........

I’ve messed around with this stuff a lot - had a thermal solar system that is in really rough shape after 15 yrs - LOVE your simple/genius approach to this!
You can just buy the ones with builtin thermostat..Then regulate the temp.... Then use a well insulated bucket with marine pump. Wallah. You got a simple shower for camping. And all it need is a 12 volt 100ah battery and 200 watt solar panel.. Which if you have that to start with. You can take a shower everyday...
Good idea,you have to put the washer and screw on the outside.I did mine,I put a 2 inch hole on the cooler about 3 inch from the inside bottom I used 2 inch circular blade drill.then I use one inch & half by one inch & half sink strainer putting in backward.I also used 4 small washer and four 5/8 electric screw,screw head is kinda round.Cooler usually one inch thick.make sure the rubber washer is on the sink strainer thread on the inside of the cooler.Don't f**k up.
Is it possible to heat up 30L of water to 60 Celsius with a 12v system in less than an hour?

sir, wat battery/panels/adapter
can we power 12v 65watt element...
How does it not melt the plastic that it goes through? I don't understand isn't it too hot?
hi there. 2 main things allow it to work. one is that the water keeps the element relatively cool (just make sure the element is totally submerged). the other reason is that the element doesn't really get hot at the base (near the ice-chest). it gets hot an inch or two out from it. *notice that the small bubbles don't form near the base. 🙂
No it won't melt the plastic at all,the cooler plastic is thick dude.i already had one,I put 1500 watt on it.i love it so much
@@fanech14 would it work with an actual water tank under mount? Or is that plastic too thin?
Have you done any analysis on how much power this takes? How many times can you do this inns fully charged battery? How do you charge your batteries back up after?

Excellent job! I really want to make one of these. Could you possibly provide the link for the Universal Flange Kit? I cant find it on Amazon. Many thanks! and congratulations again, on a job well done!!
hi and thanks. to find them just type in water heater universal adapter. here is the link to the best one (in my opinion) www.amazon.com/Camco-7223-Universal-Adapter-Kit/dp/B000BQMK9C/ref=sr_1_1?keywords=water+heater+universal+adapter&qid=1575484239&sr=8-1
Does the heating element drain your battery fast?
the question is how long will this heating last on a fully charged 12 volt battery by itself??
Discourses For Higher Enlightenment depends on the insulation of course but 12 amp draw and takes 1 hr to heat means 12 amp hours so your standard 100 amp hour 12v battery which is really a 50 amp hour battery would be able to fully re heat the water from cold four times before being classed as flat. The better the insulation the longer the water stays hot between heating phases.
@@HandyC thanks but why do you say a standard 100 amp hour 12v battery is really a 50 amp hour battery?
@@ctm130 Because every time a lead acid based battery is used, it loses a tiny bit of capacity due to degradation. This isn't very noticeable during standard use in a car/truck. But, as you discharge further and further, more damage is done. If you discharge past 50% capacity every time, you nearly cut your battery life in half. If you discharge to absolute 0, you run a risk of the battery not being able to recover.
Battery life is measured in cycles, so naturally, it does count as a "cycle" every so often. A "cycle" is a total percentage of the capacity being used and recharged.
So say you have a battery that's rated for 10 cycles.
If you use 50% of the battery per day and then recharge it to 100% that night, the battery will last 20 days.
If you use 95% of the battery per day and then recharge it to 100% that night, the battery will last 10 1/2 days.
This is obviously generalized for simplicity, but that's the idea of it. Most AGMs are rated at a couple thousand or more total cycles.
without the solar panels
Great job can we have a link to that heating element please?

Hey, how many watts does this take each hour? I have a jackery 500, how would I wire this with the 12v?
At 150W it draws 150w/hr over the hour, if the Jackery has a standard cigarette type 12v socket , thats rated at 15amps, the socket is rated at 180W, so at 150W it can be plugged straight in

Connect a heat exchanger with it and a fac on the one side and make a air heater
yep, you could connect this type of set up with a heat exchanger. i'd probably use a 300w or 600w element if you do that thou.
Where did you get that univeral flange adapter?
hi there. i got that on amazon. cost about $6. this one looks similar www.amazon.com/Camco-7223-Universal-Adapter-Kit/dp/B000BQMK9C/ref=sr_1_22?dchild=1&keywords=water+heater+unversal+adapter+1%22+threads&qid=1588266777&sr=8-22
im looking for an efficient off-grid camper application that runs off 12volts. Add a DC
submersible temperature control switch to regulate the temperature and shut off the element when unnecessary and a float switch combined with a normally closed relay with two submersible DC pumps, one in the cooler which is controlled by a switch and another pump in a water holding tank with hose that feeds into the top of the cooler. Line in and line out. The float switch opens the relay which turns off the pump in the water holding tank when the water level gets too high meanwhile the switch for the pump in the cooler allows you to turn on hot water when you need the pressure to use it. The whole thing could be used straight off the batteries in a 12volt solar system. why they do not make a 12volt all in one water heater is beyond me.
So how do you keep the water from soaking into the inside and outside layers of the cooler? I tried to make an insulated chicken water with an insulated jug and water ran in between the two layers and leaked.
hi there. most ice chests have a type of 'foam insulation' between the inner and outer walls. the foam keeps out all the water. i guess some really small containers skip the foam insulation (so you'll need to use one with it).
Can I ask where you bought the heating element?? If you have any suggestions from shops online that would be really helpful...its just for a really important subject
hi there. i got the heating element on amazon. it's a 12v 150w dernord heating element. i just checked - they still have them ($22.99) 👍
Where did you find that flange for the heating element? I can't seem to find it. I'm talking about the part you siliconed to the cooler. Any help would be appreciated 👍

Amazing Dude
hi and thanks ⭐
The element doesn’t melt the cooler?
hi there. nope, not at all. if you look close, you can see the element doesn't even get very warm near the connection (the threads). notice how the bubbles only start forming on the element an inch or two out from connection. must be a safety feature they build into them
Hell no ! I put 1500 watt on mine.
How many watts? Can it be ran off a car battery charger?
hi there. the element i use is 12v 150 watts. they also sell 12v 300 watt and 12v 600 watt ones. some of the 300 watt ones are cool because they are actually two 150 watt elements 'combined into one unit'. each has its own terminals so you can run just one of the elements if you want.

Any 12V 150W heating element will work?
hi. yes, as long as it's a water heating element any brand should work ✔🙂
Do you have any advice or can point me in the direction of a wiring diagram for these? I have a twin element one and it took a very long time to heat up and used a lot of battery! Many thanks
hi. i've never used a twin element one. those are 300w or 600w if i remember. the 300w one i saw had 2 150w elements. is that the one you have?

Hi dear, nice video, can i connect for example a solar panel 300w solar panel to a 24v water heater?? warm up before

hi there. it depends on the voltage of the solar panel. if the voltage is near 24v or a little higher i'd say it should work

Interesting. But how would could you stop getting too hot if using the solar setup?
hi. you could add a thermal shut off switch. set the temp and it cuts off the power at that temp. amazons got em. they're not much either. one for 7.99 or 2 for 10 🙂
@@desertsun02 On doing some research I found some elements have a thermostat which were fairly inexpensive. I can definitely see myself going for this kind of setup.

@@desertsun02 I really like this concept. For the temperature controllers on Amazon, have a couple questions: 1) Are the sensors submersible in water? 2) Do they have the ability to relay the amperage of the heating element (12.5 a, right)? Can you recommend a specific model?

@@desertsun02 Thank you ever so much for , your expeditious response , have a peaceful evening!
@ELKA SIDAV thank you. you too.
I tried connecting up a 400 Watt panel to one of these elements rated at 12V DC. I mounted the element in a tank of water. When I checked the voltage in the circuit, it was reading only about 3 volts. It didn't seem to be getting hot even though it was sunny outside.
Any idea what is wrong with this setup?
i can't think of anything that would cause the voltage to be 3v. possible things to check would be to take a reading on the panel (without the element attached) to see if it's working right. make sure you are using wire that can handle the amps. make sure connections are tight. it could be a faulty element (but that is unlikely). the elements are very tough. make sure nothing is covering even one cell on your panel. many panels will barely work at all if even one cell is shaded. the funny thing is that if the entire panel is shaded evenly then it still works fairly well (but a little shade on one-half of just one cell and there is a massive drop in power). only other thing is are you sure the panel is 12v? nearly all 12v panels are 200w or less. 300 or 400 watt panels usually have much higher voltage.
@@desertsun02Hi. Thanks for the reply. You are right, the panel is 33V open circuit, but I thought that higher voltage would have been an advantage? I measured the voltage coming from the panel to be about 33V on a sunny day. I measured 3V across the terminals of the element when connected to the panel. The element has 12V 300W stamped on it. When I connected the element to a 12 volt battery, it did get very hot, but the battery was draining very quickly and the voltage was dropping. So I would rather have a system which does not use a battery, just solar panel.
Question? Can I just wire the element to a deep cycle battery? I have a 300 watt element and some 12 awg wire. Thank you in advance.
hi there. yes you can. a 300w element might pull about 25 amps though so you would probably want to use a battery bank. you may have to use a thicker wire too. you might want to use 10 awg or even 8. i'm not sure if 12 awg will handle the amps.
@@desertsun02 thank you for responding. I happened to have some 8 guage wire, added the proper lugs and 30 amp gator clips. I used a bulk head fitting to install the element in a 5 gallon bucket and a rechargeable portable water pump with a shower head. I plan to use this in my tiny 1967 camper. 300 watts may not heat up quick but it does work with very little work on my part and won't cost a penny here on out. Im using 210 amp hour deep cycle batteries with a Victron Battery protect to prevent under voltage. Super cool diy project my friend! Thank you.
I just received mine but I can’t tell which is positive or negative connection.
Do you know which one is positive?
hi. it seems strange at first but i don't think it matters on some of them.
@@desertsun02 ok thank you
Is there any way to do this without drilling a hole in a container?
hi. that's the beauty of it. you don't need to drill a hole in the container. it's already there. all i did was remove the plug assembly and put in the element. by the way if you don't want to use a container with a plug i have another video that shows this element mounted in a 1 gallon glass jug. it gets the water boiling. here's the link ua-cam.com/video/kOmGu8Uz674/v-deo.html

Interesting idea. Have you had any problem with the element melting the plastic on the ice chest? I know you used the 150w element, so it's not as hot as a 300w unit. ....I get that the element has to be submersed.
hi. the element won't melt the plastic. it doesn't get that hot near the connection. (look close at the bubbles that form on the element, none form within an inch or two of the connection) as that area is not heated very much. that plus the water keeps it plenty cool. about the 300 watt elements... they are usually just two 150 watt elements mounted on the same threads (and interlaced) to make one unit. each of the elements is the same temperature as the 150 watt model. it's just a second interlaced 150 watt element. *usually with a second set of screws too (so you can run the 300 watt ones as a 150er if you want.
@@desertsun02, thanks for the quick reply. I wasn't aware that the 300w, 12vdc elements are two 150w units in series. DC elements make sense as a dump load for a small wind turbine or independent water heating source. If they don't impact plastics when submerged, that makes them more valuable.
Can you get me a link of where you found a 12v Water Heating Element? All I can seem to find is a 120v element.

@@desertsun02 Thank you
Anyway to control the temp to what temp you want?
You would need a thermostat inside the ice chest that disconnects the 12v power when it reaches a certain temp and turns it back on when it drops below a certain temp.
Why?
hi. why not?
I want to build one of these, but you don't show how to hook up the power? What do I use for a battery or batteries???
hi. you can use any 12v source that will give you the amps. it pulls about 12.5 amps. it's a straight connect from the heating element to the power source. you can use a 12v deep cycle battery or batteries. you can hook it straight to a 12 volt solar panel or panels. (i hook it to two 100w 12v solar panels). it's only 12.5 amps so you can even run it using your cars' 12v power socket (assuming the fuse for that socket is 15 amps). you can also run it off of an ac to dc transformer (i use a 15amp one).
@@desertsun02 A lot of this is new to me. Is a 20w Solar Panel not gonna work? Or will it blow something......I assume I should just connect batteries that total 12v and just call it good.....?
hi. a 12v 20w solar panel won't work. that would probably only be a 1 amp panel. 12v 100w solar panels usually produce 5.5 or 6 amps. i use 2 of them to get to roughly 12 amps. if you're going to use a 12v battery, it should probably be a 12v deep cycle battery.
