How The $50 Solar Water Heater Works And How To Build It 

Because quite a few of you were asking for more details on the construction of the panel after the last video ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mFC_93DW_XQ.html ) There will be a more comprehensive step by step construction tutorial coming out before too long, this should hopefully help get you by til then. Any questions let me know.

Looking forward to the panel details for heating the water as it's so different to what we do in the uk. Fabulous idea big sheet of metal to hear up in the sun and a small gap for water to flow thru... Genius. Thanks

Nice, but closer to $500 than $50. The copper tube alone is over $50. I can find 50ft for $97, and this requires 30 ft. The tank is also over $75.

Would it not make sense to insulate the upper reservoir as much as possible to avoid heat loss to surrounds? Anyway, excellent low-tech but high-gain project, I love it.

Thanks

Thanks for the ideas man!

It is incredibly simple 😎

Wow very well

I like this thanks 😊

Very cool project 😍

excelent, thanks

Well done 👍

So cool 😎

Surely the heating element should be at the bottom where the cooler water will be. Heat raises.

Even after replacing the rings the water is leaking but in12-14 tubes.Should I again remove the rings and refit the tubes?How to ensure that the rings are correctly fitted ?

Great stuff! Thank you!

Wonderful? Do you have any idea of the weight of the installation ?

you want the hot return to enter at the bottom for a more even heat.

Been wondering: How many have ever tried to capitolize on the very same set-up for cold water? One simple valve would switch from a hot tank to a seperate, cool tank. Direct the cool water (or fluid) to serve as an AC. May be weak, but, cool your living space with cool air, and, if needed, use a window unit to make up the difference. Two tanks: one for hot, another for cool. Insulate them both, very well, and BOOM! No energ6 to heat and much less energy to cool. Winter AND summer covered. The water (or fluid) is not consumed. The lines don't wear out, the tanks don't wear out. Electric fans powered by solar-batteries. Again, if more cooling and/or heating is needed, use solar powered heaters and window AC. Compare the monthly energy cost with the cost to make this... Only takes a year or two, and, BAM! Your saving money... Your welcome, no charge.

Hi may i ask a few questions please? (i like ths graphics) >I get that the hot water in the header tank is insulated and acting like a heat collector. Does it need an air pressure pipe in case of overheating? >I can see that copper tubing is located at the top end of the heated water, does that mean it needs a pump to circulate the water into another water container for use?. If not, does it create enough heat by using it straight then, with mains and out into a shower head? thats interesting. Im curious about what the benefit are for using copper pipe in this way. *Ive made a few of these for festivals... Instead of having to fill the header tank by hand with water, you could have a stop cock to automatic it and it wont run dry. Usually we have mains and a T juntion for a cold water feed, the other half goes to a header tank above everything. The system is fed by gravity, cold water goes all the way down to solar panel / or wood burner input at the bottom of everything. Hot water circulates up into a holding tank (in the middle), with another T junction, of which is an air pressure pipe that goes back up located above the header tank for an emergancy steam vent. The other half comes off this T as a hot water feed. Cold water and hot water join at any shower head and or outisde kitchen sink. All the best, just curious

Surface area is the key

The irony is not lost on me, as someone who leans by watching, that we did not see the how of it when it was done visually only to have it show as drawings. So now there are plans without explanation and a video that does not show how. Perhaps a podcast next?

Sorry, I was just wandering if you can get legionella in this system ?

can i get the card drawing for each of the parts

Dumb question, what do you do when you want hot water at night?And could this be used with a trough type black tank and set it on a roof to integrate the design and not look like an eye sore?

why spiral ? why not directly heat water and use it ?

Any testimonials?

What application do you for that simulation

What does the copper coil on the inside of the reservoir so.?

Во первых, вода в бочке и в нагревательным элементе быстро позеленеет из-за развития сине-зеленых водорослей. Во вторых, иметь бочку с горячей водой, но использовать только половину ее объёма - это очень глупо. В третьих из этой половины объёма горячей воды использовать не саму воду, а использовать тепловую энергию с помощью медного контура - это очень сильно снизит КПД всего устройства.

Would an inverted half mirror foil work before the heating plate?

@OpenSourceLowTech Hello, I am trying to help my brother-in-law in Thailand and trying to help him to find a solution for Hot water out on his remote farm...My Wife is flying out to Thailand on April 4th and I just want to help him out...I am trying to understand 1.0 Panel - Assembly??? May I learn more please??? Liked#481 and now Subscribed!!!

😊😊😊😊😊❤❤❤

Surprise it does not leak only metal washers and no sealant? silicon washers + metal washers + screw? or cheaper option is to apply some silicon tube when screwing down the metal washers. silicon is better then rubber washers, higher temp and longer lasting.

This wouldn't work, as the water from the heater panel can not rise back up without a pump..... Unless you use over dimensional pipe sizes....

this makes no sense, why make two heating system ? Why not using the hot water directly. Connecting the heated water to the bottom of the reservoir instead of the top, and therfore heating the all reservoir and using the water directly instead of having to do a heating spiral tube ?
