Great concept..but plastic pipe.. getting heated.. would leach dangerous chemicals into the water! Better use copper...and a insulated stainless steel tank to collect the hot water. Hugely more expensive..but you will save on futre medical bills!!

all instructional videos are better without backgound music on repeat!

We heat our above ground pool this way. We have all the black flexible irrigation pipe/tubing mounted on our garage roof. But we do use a water pump to circulate it from the pool to the roof heating coils/tubing. And we are located in Western Canada. We have had it now for about 8 years, works great.

Mi abuelo los fabricaba de manera profesional usando el principio que ahi se ve.... Y claro mas eficientes el agua hervia al salir y se mantebia caliente por muchos dias aun en dias nublados, Calentadores de sol America....ganaron varios premios en diferentes paises..hace mas de 50 años

Use copper coil, circulate water, insulate tank, and add solar tracker for better results

Would work a lot better if the reflector barrel was parabolic. A lotta' heat not even being focused!

Try that in the UK, 17 degrees in probably 10 degrees out.😅

Simple, cheap and efficient. Like this good engineering should be.

Interesting idea. But you need different material If you want to use the water for drinking and cooking...

you should run the water from the valve back to the tank and it will heat all the water doing it the way you have will cause the water inside the reflector to continue to heat till it boils and scald you and only supply you a small amount of water. I also built one use copper tubing vertical and sat it over a small fire just to heat washing water that could be lifted of the fire when sufficient hot water was made using the same lay out that you have used here

Always 👏 people applying themselves, maybe try a copper metal coil instead, better conductor of heat.. or possibly a glass coil to receive sun light.. Hope and wish you results..

Great if you have sunshine. It might heat 1 litre a day where I live.

Perfect. Thank you for sharing

You must run the pipe back into the water tank to circulate by convection when not in use because now you are only heating the water which is in the pipe which is not much. Nevertheless great job 👍👊👌🙂

Further improvements can be made by painting the outside black and pumping the water around true the pipes and into the barrel again, then all water will become hot. That is to say, if the barrel is isolated on the outside with very thick polystyrene and is painted black.

Awesome idea brother

great Idea for off grid campers. Could easily made portable.

We built something similar (a pool heater) for my son's pool. We raised the temperature on average by nine degrees every 24 hours for three days before it stopped rising.

If you can rise the temperature to 100 C and it's possible by the way ,then you can use these free energy to desalination of sea water and saving the planet and the humanity 💚 I'm totally proud of you man

Thank you good video

Super👌

HOW much heat does this receiver get from the sun SIR ?? Simple and really works for free.

Super 👌

Very good! Cheap to build and effective. For Europe or North America only works for maybe 7 months. Awesome for cabin or camping! Drain into a giant thermos and youd have tons of hot water

You are a genius!

Brilliant! Thankyou for this.❤

You could connect it back to the barrel and let convection circulate it back around to eventually heat the entire barrel of water.

I guess the drum is about 300 litres at best so how are the other 2,700 litres heated?

Brilliant.

Very nice Brother

Great idea and effective. I would make some minor modifications but you got me thinking. Fabrication was very neatly executed. Thanks for sharing 😊

Excellent... (Lower background noise😅)

Es ist ein Durchlauferhitzer

Copper tubing absorb heat better. With black coating

Hmmmm, great idea, even on a cloudy day it will still heat some.

Теплообменник надо устанавливать в фокусе оптической системы,такое впечатление что в фокусе находится ось трубы теплообменика а не поверхность спирали.На юге,в качестве зеркала достаточно большого старого таза покрашенного аллюминевой пудрой, а металическая бочка,с запорным клапаном от унитаза,это теплообменник и накопитель.С уважением к Вашим идеям.

Buenas , el sistema es bueno , pero no funcionaria ,puesto que las temperaturas que se alcanzan de mas de 100 grados centigrados fundirian esa goma. Habria que hacerlo con cobre y para mayor rendimiento tapar parte superior con cristal o algo parecido aislar y meter una pequeña bomba saludos Hello, the system is good, but it would not work, since the temperatures that are reached of more than 100 degrees Celsius would melt that rubber. It would have to be done with copper and for greater performance, cover the upper part with glass or something similar, insulate it and put a small bomb. Regards

Excelente 👍🏻

So haben wir zu DDR Zeiten schon warmes Wasser erzeugt

If the mirror was a parabolic curve with the pipe at the focal point it would be capturing much more of the suns heat. As it is a lot of the sunlight hitting the mirror is reflected straight out and wasted. It might melt your hose though!

Low-tech, cheap. Perfect!

unreal! With the given reflector and heating the water by 25 oC, I estimate a maximum of 300 l/day

Good idea but the flow rate looks pretty low . Get that barrel up higher to increase water pressure and it should be okay for a nice warm shower .

i seen little stainless food grade barrels and wondered about that type water heater,,Sunshine energy make me hot tea🙏🏼

Would rather want to know the temp in the storage unit. Considering heat rises, mayHap the colder water will constantly sink to the copper coils Replacing the heated water? My tropical home.. near boils the un-insulated house water pipe that runs in the roof cavity and stays hot well into the night in summer :/ (tin/metal roof)

Also make the top glass or Perspex a one way mirror.

i actually build water heated house warming systems.. for a compagny . i would recomend to use copper pipes instead of the hose laminate them with black aluminium forgete about the pipe in the middle maken them flat. pump water true it and it will get you way more whot water...

Nice. Paint the Wood, it will rot fast when the Rain hits it and make a whole that rain can go out. I would use a black Container then blue but good Idea !

Your reflector is round, thats not perfectly focused. It needs to be parabolic (flatten out the curve a little towards the edges)

Donde puedo contactarte por favor

This is a marvellous idea. It's easy, cheap an reliant. You can easy heat up the water collected by a canister from the rainfall on your roof going down the drain pipe. I even have a quite cheap proposal for upgrading the system. The idea of using a glass sheet to get internal reflection and thus a higher yield of thermal energy is great. But if you would coat the tube in prior with a black color, which is IR reflectant, the tube would heat up even more, since less light from the VIS range is reflected (1. Loss) and less thermal radiation is emitted from the tube (2.Loss). In theory you should be able to boil the water. If this doesn't work yet, one could easily scale the system, so that the tube length is doubled, so more thermal energy is flowing into the water passing through the pipe. Unfortunately I wasn't able finding a simple shop where you can buy such a color yet. But many research paper state that it's actually possible and I even found a company who fabricates such pigments for making IR reflectant colors. The (i think) most promising Pigment should be (FeMn)2O3, which is actually also quite common in nature. Good Luck and keep up the good work.

In summer we don't need hot water ...and in winter it is hard to see sun in sky .Tell us the method which helps in winter with no sun.

When the shtf big time and the power is gone this would be awesome for an old time shower. Like once or twice a week!

Estaría genial que se pudiera calentar el agua de una piscina, es decir, pone el depósito de agua debajo y el generador de calor arriba

Hello, how do I know what are the materials needed to make the project? Do you have some kind of list or a video explaining or narrating every step?

After that store in a thermos container so that the heated water will remain for much time

I think instead of jumping into 'how to', maybe talk a little bit more about why and what exactly we're doing at the beginning.

Materia should be black colour - better absorbs sunlight and holds inside 'cause of covered with glass...

What about in middle of winter below 30 degrees

In Pakistan, but northern Europe?

The whole point of parabolic reflector is to concentrate energy on a point. Maybe video distorts dimensions but it seems pipe is way to close to back wall (not at focal point). Most of the light bouncing off reflector is just shooting right back out without hitting hose.

cool, hot water when it's hot outside.... What about the winter ?

Surely make sure max flow rate by ensuring entry/exit of pipe in not restricted then throttle down if needed.. Maybe micro comp control🤔

I think you could save some money on hose, by using a wide pipe instead of a coil. Same amount of water in and out; less copper

A good basic idea 95% of people could probably manage it ........ until you switched on the welder when it dropped to below 5%

Can I use this idea to heat the pool?

The curve should be parabolic !

perfect teperature for legionella bacteria. 50-60 celcius

Cover the heating position with double layered glass to trap heat

Also 70 degrees are possible, it depends on how log the pipe Haß been standing in the Sun before you fill in the water. Want See how it works with constant flow of 7-8 l/min

And if there isn’t any sun and is cold ? This work for your area not in UK or where are the mountains which is always cloudy

Wonderful! Warm water when the sun shines. Meaning not in the morning when i need it for showering or in the evening when washing dishes or whatever. It is right available when i am at work and not at home. Another green energy solution wich is completly useless for nearby everybody.

Like hot country,s it would work anyhow. In Europe it will work as well, only not this way

Uno de los pocos vídeos que he visto que sea verdaderamente útil.

It wouldn't work in the uk cos the sun rarely shines cos it pisses down most day's

Does this work in winter?

You can also run p v c pipe or black poly irrigation pipe over the roof of a house , shed , building and the sun heat the water inside the pipe for free🙄🤔

Mare atenție însă! Nu expuneți la soare un concentrator solar fără apă în el poate lua foc 🔥 nesupravegheat , mulțumesc 🙏🏼😌😇

300

What kind of hose is that and where did you buy it? Link?

What are the total costs of materials?

What do you need 3000l of water a day for in a hot climate ? That blue barrel holds how much ?....which means you have to top it up all the time. What is the Focal point of the parabolic mirror ? Many many questions.

🆒😎👍!

ඔකට තබ බට යොදාගත්තනම් හොදයිනේද?

Garmi mein plastic tank to wese hi garam hota hai aur 50 degree se zayada garam pani deta hai. Rat ko yeh kam ni kare ga. Aur sardion mein to bilkul bhi kam ni kare ga.

If you want some good ideas ....try u tuber green power science ....he has lots of these kind of videos !! To O.P

Why would they use counter sunk screws like that? This is just bad. Then you don't even circulate the water back into the blue drum. You would get better results if you just painted the drum Black.

Great concept . . . . hardly "free".

where may i order

where may i order, how do i take a shower

Would be much more efficient if the whole inside of the box was painted black. The whole inside would reach easily 70 degrees or higher

Plastic insulates. Metal conducts.

Very interesting. Is it safe to consume water that passes through copper tubing?

All those troubles, time spent and resources expenditure just to warm water? 46⁰C isn't far from body temparature 37⁰C; leave. Pour the water inside the diameter shaped cylinder and leave it under the Sun for 30mins, its still same result

please what is the name of the pipe you used in the project?

Hay gente muy 🤯

👍💵😜

How about raining days @_@?

Where can I get my "free water heater"?

Why did you not put the return water tap piece to circulate part way up to the barrel The water would get much hotter. and you could use a much bigger barrel
