Nice video filled with good tips & trix. I'm setting up a solar powered pool heater right now and my goal is 30°C / 86°F. I'm starting with 250 meters / 820 feet of 20 mm / ¾ inch PEM hose in a flat rooftop setup. A 20V rainwater barrel pump (2,000 liters - 528 gallons / hour) will be connected directly to a solar panel, so it's a completely automatic system controlled and powered by the sun.
No sun = no pump = no heating.
Since I'm located at 60° latitude in the northern hemisphere, I'll guess it'll be some problems to solve along the way, but it'll be fun.
Keep up your good work
Did similar in the ‘80’s in Northern Indiana (Winamac) with a 3ft X 8ft farm livestock watering tank pool. Routed a garden hose from the pump/filter, coiled the hose on a slanted square of plywood (Sunward facing) then back into the pool. Sprayed the hose with black paint. Took the night chill out of the water every day without the use of a glass cover or box. The kids loved it.
Seen few die solar panels videos, this one is by far the best
Excellent idea from an old window, thank you for the video!
Absolutely fantastic solar heater! Well done my man well done.
Thank you :)
Для эффективного поглощения нужна не просто черная краска, а специализированная светопоглащающая краска и стекло чисто кварцевое с внутренним отражающим напылением(пропуск ИК лучей только во внутрь). Хотя конечно это все дорого и прибавит процентов 20% к эффективности преобразования. Для проточного нагрева воды от солнца необходимо минимум 3 м кв. поверхности при 100% КПД. В данном случае нужно не менее 8 метров квадратных для проточного нагрева. Принято считать, что 1 ватт греет воду в объеме 1 литр на 1 градус.
good idea, i did the same years ago less professional (wooden frame, 3 pipe coils, plexiglass plate) but just a risk, the problem concerns the polypropylene pipes which with heat and time will pierce ... it is necessary that the water circulates permanently otherwise there is a too strong rise in temperature, and that kills the pipes
Красавчик! Отлично сделано!
This is a good video. You can run larger pipe - say 200 feet of 1 1/2 black pipe as near as possible to roof to heat and store more water than this. As anything with solar alone - output is greatly varied - but definitely efficient.
EXCELLENT WORK! QUALITY AND FINISH IS INDUSTRIAL GRADE!
Woooo, eso me preguntaba yo !! Si se podría poner cristal y luego la manguera !! Muchas gracias !! Excelente video!!
Nice design, very neat. Hook it up to a water butt and solar powered pump.
Hi, you should point in the description that you reached this temperature boost after some time of heating water in the collector. It's impossible to reach such good results with a constant water flow around 10l/min (9:20 - 10:20). Math says that in such case, with collector size 1m x 2m you are able to boost up the temperature about 3C as the sun provides about 1kW per square meter. It's still better than a nothing. Cheers.
Very nice. I’ll take the version that mounts to my south facing roof. Better to heat water then burn my shingles LOL. I’ve been watching a lot of these videos and I find myself wondering why some manufacturer doesn’t make a 4 by 4 foot evacuated glass “pocket” to place a heating tube inside. The methodology, simulator to a solar tube could actually boil water. Your are blessed with fine workmanship and ideas.. well done !
Thank you
Professional work.
WOW I need one of this heater on my roof for the all house.
The best I've seen so far. Thank you very much for sharing. The best for you :)
Ppppp
Brilliant! Looks snazzy too. Too heavy to carry around... maybe you could mount it in the pool house.
You could gather more heat from the sun if the top surface was lightly etched to keep the rays from deflecting off the glass.
at least the outside layer of glass is treated with oxides against infrared
I tried once to pry open a double glass in vain, it broke, am amazed you were able. 👍
Carburettor cleaner softens the sealant. Still a horrible job though.
let it sit in the sun makes the butyl soften, see if there is a stamp on the glass if so that means its tempered, tempered glass is four times stronger than annealed glass.
I pried my glass off in a cool garage, so I heated 18 inches of the edge with a heat gun 700 degrees, after a minute I slide my knife under the glass and was carefull to keep the knife tight to the glass ( not in the thick of the butyl glue) I kept the heat on the knife and the glass and slid it easily. The window does move so you need to block it, if youve got both hands on a knife and heat gun. I also put a wedge small bolt under the lifted window , so that it didnt fall back on the hot glue and get stuck.

BENDICIONES PARA TODOS
Muito boa ideia gostei, estou com esta mesma ideia com uma caixa de geladeira quero fazer um reservatório como um boli para coloca água quete no banheiro.
boa noite vc fez?
Bellissima idea, complimenti, forse ci vorrebbe un piccolo puffer per essere al top 👍
I've seen a similar thing way back using a single-glazed frame (before proper double glazing was common) fitted with a wooden back board. The water was passed along thin copper piping in a zig-zag fashion and painted black for maximum solar absorption. I would be interested to see if that performance can be maintained at the flow rate you show, I get water at that sort of temperature from my garden hose water that has been heated in the sun all day before I turn the mains water on: it runs like bath water initially of course but soon runs out of steam. Yours is a really nice project but I think you'd need a few dozen of those to make a significant difference to a small pool. I love the idea though so well done.
the power ist about 200-300 Watt. You need a minimum of 20!
Professional Work. Very, Very Good.
Thank you
great caulk hander
Brilliant idea!
Nice work man,very accurate,detalied🥇🔆🌞🏊♀️👍
Greetings from Estonia!
This is definitely the best looking solar heater. Heck you could reinstall that in the window. Cut my finger trying to undo a double glazed window. Just cause it looks smooth everyone needs to wear gloves! Thanks for the lesson.
Imagino um desses aqui em PE, onde a água já sai queimando da torneira kkkk
Выходную температуру надо измерять при полностью открытом выходном кране. Дельта входной и выходной температур в пару градусов уже будет достижением. И да, как тут было замечено, верхнее стекло не надо чернить, КПД получится больше. Написал, имея 6-7 летний опыт прогрева купели в закрытом помещении аналогичным солнечным коллектором.
При минусе на улице ? Скважина 44 метра в глубину ?
Muito inteligente . Devíamos aprender para não precisarmos mais de pagar conta para as Empresas de Energia .
Amazing!!
Perfect
just watched a video of geothermal system. He could add a set of these to make his system even more efficient!
hmmm,never thought of painting the glass black,just the interior...background and pipes...looks very nice
I would think the top piece of glass would actually hurt you as most glass today is designed to reflect some sunlight
Génial, ça réchauffe une carafe d'eau en 2 minutes...
Very ecologic,,,,Thanks
I saw this done with copper pipes and water came out as steam it wasnt used for pool though.definately bug free water good idea.
Wonderful work
Ingenios,buna idee si pentru alti amatori
This is my favorite way to adhere the pipe to the board so far. I'm wondering if the intake and outake side by side is less productive as far as overall temp is concerned. How are you finding it now that you have some time under your belt?
Following.
Also wonder if a slight gap in the hose circular pattern wouldn’t increase mass of pipe exposed to the heat generated ?
@@roberts4411 it would be better if there was direct contact with a high heat capacitance material. I've laid myine out on a shed roof, so it'd conduct some heat from that.
Last year I built two 4x4 boxes for my 18x48 above ground pool with 200 ft of quality heat resistant 5/8 water hose with brass fittings, the plastic ends will melt and a cheap hose will melt the inside. That was my first mistake, bought cheap water hoses. I ended up getting Good Year hoses. Even though the water hose was black i spray painted them a flat black. I had an old front window from my house for one box and some old shower doors for the other. Cut the ends of some soda cans and put as many as could fit inside the box with the hose and painted flat black. The cans act like a vortex of heat. I use to Y off from my 12 inch intex sand filter pump. Just switch over from pool to solar boxes. I would run a big hose to a smaller hose into the box witch would slow down the flow of water. As the day got hoter i could let the pump run the hot water continuously. I just bought the 16 inch intex sand filter pump but has to much pressure for my hose, so i use my old 12 inch pump directly to the solar boxes. I live in San Diego so the average temp is around mid 70s to mid 80s. Iam in my pool around mid April. I keep a solar cover on it when not using and will lose a couple of degrees at night. I have the pool wrapped with 4 layers of 4 mill plastic witch helps. I keep the temp of the water around 84 to 86. I have got the water up to 90. I will let it get to 88. I have tried the irrigation plastic stuff before but it melted inside. I made many mistakes before i got it right. My neighbors with there nice pretty pools are sitting at the edge of the pool with feet in and i am swimming in my pool. I like to get in the pool early in the morning when the air is cool and the water in my pool is at 84. Those solar boxes get very very very hot, you will burn your hands
thanks for your informations
100 ft in each 4x4 box?
Any chance you could put a picture up somewhere of how you used the cans as a vortex?
What brand of hose did you purchase? Not understanding how the hose could melt if cool water was running through it. Was the water turned off? Thx for any help offered.
Cold water in the pipe will absorb more heat than hot water, because of the greater temperature differential (that's simple physics). So it's a bit counter-intuitive, but it is better to keep the water flowing quickly through the heater pipe, whatever the temperature. I.e. it is better to heat a large amount of water slightly, than a tiny amount of water to a higher temperature. .Just cycle the water through more times.
You could have cut the 200 foot length into shorterr, and had more parallel tubes so the output didn't get so hot. Keep the water flowing more quickly so it never gets hot enough to melt even cheap plastic hose, and the whole pool will heat faster.
¿Usa válvulas de entrada y salida? Gracias y felicitaciones.
Wish I had seen this method of heat water when we had swimming pool
It would have been great if you could have measured the input and output temperatures AND the water flow rate so that the net power of the heater could be worked out. It would also be good to know the size of the collector so the power per unit area could be calculated so that the heater design can be scaled up or down depending on an individual need.
Otherwise, an awesome idea to encapsulate the coil inside a double glazing unit.
Так сложно, со стеклопакетом заморочился. Ну браво - хотя можно было более изящное решение найти:) Вода кстати хорошо прогревается в шланге.
Me gusto tu supervisor : el gato jajajaja buenisimo
good idea. thanks for video.
Muy novedoso pero si quisiera un vídeo más explicativo como cantidad de agua que puede calentar materiales utilizados y todo eso ,y si nos das un contacto exelente
Nice work!
Thank you :)
Good quality! What kind of pump do you use to moving the water? How loud is it? Thanks for your answer in advance.
yes, if you trickle the water through the hose i'm sure it gets very hot
Capo genio total!!!!
Great job!
Thanks :)
La idea es muy buena, sí se la pule un poco. La tubería de entrada, no puede estar pegada a la salida, porque hace de refrigerante. El agua que calienta el sol en el circuito al salir del sistema, se enfría por el choque térmico con el caño de entrada que trae la alimentación de agua fría al circuito.
Very Elegant!
Very neat work, but painting the top glass black will just serve to reflect the sun's rays and reduce the overall efficiency. And I bet if you pump the water through at a decent rate, when a steady state is reached the temperature gain will be minimal.
Super Video.Danke!
Thanks :)
@@kukomio Super ❤
нижнее стекло и шланг-трубу в кипельно матовый черный цвет (глянец отражает много света и тепла), результат будет намного лучше, да и верхнее стекло не закрашивать. идея крутая, эстетика есть, но можно добиться выхлопа по градусам выше
Good idea.
Attention only max 500w/m2, not a power revolution, in hte better position : well oriented to the south, etc, etc,,,
Be carefull to the condensation.
Fine business !
Genialne
Excelente idea pero ya ay una nueva presentación de manguera de silicona y funciona estupendo
Très beau travail ...
Your mentioning low volume of water passing through the coils is super important as the black tubes are not good conductors of heat, like copper tubing would be. Therefore, run the water through very slowly, giving the water more time within the coils to absorb more heat. Good DIY project and can be done so inexpensively. I have used this same system since the early 1970s.
Don't think it makes much difference running the water slow or fast.
Energy is the same
If you want to warm up something quickly, you have to raise the flow. Cold water warms up more quickly then warm water ;) So if you would use this for like a swimming pool, you want higher flow rate. The water that is comming out will be less warm but you have more volume that is slighlty warmer then your pool water
This is a common misconception about the science involved. I heard the same argument with car engines and radiators. The fact is that heat transfer occurs more quickly between more widely disparate temperatures. By moving the fluid more quickly, you expose cooler water to the heat in the tubing. That is a more efficient strategy.
It was not a good idea to paint the upper glass, too. In that way the solar energy gets transformed to heat at the inner edge of the upper glass. That directly heats up the upper glass and that is cooled by the outer air. Almost nothing of the solar energy hits the coil directly. Change the upper glass to a clear unsprayed one, and everything’s fine 😎
FYI, painting the upper glass will protect the tubing from UV light, which could damage the tubing over time.
@@OldMadScientist aren't there UV resistant tubes that could make better use of solar energy?
Definitely do not want to paint the upper glass you want the full spectrum of light including radiation to heat the pipe..glass serves to prevent heat loss due to convection..by painting the upper glass black you will be defeating the whole point of the glass in first place .
Glass itsself blocks alot of UV. And could do clear coat on the tubing aswell to protect it.
Yes it will cut off about 50% of energy. E. G. black Windows in busses.
Grande idea!!! Funziona
Thanks for the vid. But can we do something about every single 15-minute youtube hero adding cheap China techno music to their vids? Please.
Hi..This job 100% butifull..I love it and like to do that,Can youplease explain me where you connect the in/out sides ?
And I did Not understanding how the water flow - is it need to be connected to the pool pump Or it can be "on the side"of the pool and the heated water will do the circulation ?
I have on-above ground 3X5 X1.2m pool.
Thank's for this nice video /work
Very Thanks for good idea. As i undestood 16 C befor and 46 C after heating. But what is temperature of air ?
Plus simple: Je déroule un tuyau d’arrosage dans les gouttières de la maison exposées au soleil .Longueur environ 40 mètres .Après 30 minutes l’eau sort à 60° . Je peux alimenter si besoin ma douche de piscine ou avec une dérivation apporter cette eau chaude gratuite dans la piscine .
how much hot water can you produce with this per minute/hour? and temperatures?
Nice
Exelente!!
Gracias :)
great！
la ultima capa de vidrio tambien tiene aerosol?
I wonder if painting the recipient side of the glass isn't less efficient than keeping it clear. In cars and greenhouses the temperature will be lower when making the glass darker or painted.
superbe travail, très bien conçu et fabriqué...!! reste à savoir pour combien de litres d'eau d'une piscine ce procédé sera-t'il valable... Bravo en tous les cas pour la superbe finition de ce montage...!!
Dans l'Est de la France et avec unes solution encore plus artisanale : Le serpentin directement sur la toiture (assez plate), une feuille de polycarbonate posée dessus et maintenue par des briques et un piquage en sortie de pompe pour alimenter. Résultat: un mois de gagner en amont et autant en aval sur la saison…
you should not have painted the front glass black it would have worked better if the sun could heat the pipe and back panel directly ,, it would get the water hotter , if you constantly let the water run thru it ,, sure if you just let it heat up and "then" just open the water and take the temperature ,, but good job looks awesome'
Bravo
Hello, excellent work, just one question, how many feet of hose did you use in the video, greetings and congratulations.
If the glass is black, the sunlight going to the pipe will be less and the water will heat less. Glass should be transparent.
above side yes
is that irrigation hose, great work
Thanks
Muito bom. Fique pensando... Você colocou o vidro e se precisar da manutenção?
What could go wrong? Does the plastic pipe rust?
This just needs to be used.
I wonder if cleaning the inside of the glass with paint thinner and then painting it with ultra black might increase the heat absorption? I would suggest using soft copper tubing painted ultra black. The non sun facing side could be insulated with foam to prevent heat escaping the non facing side of the sun. Maybe the area on the edge of the heater could stage temp sensors, and and a digital flow meter.
If the whole double glazing were used and not cut, it would be more efficient. But then another extra cover would have to be made under that double glazing for that hose.
wonderful..
The answer burns brightly above us in the sky.......
Great job this was my plan for doing it since I have an old window I just didn't know how to connect the inlet outlet pipes won't the tent on the secondary window stop the Sun or is it on the inside of the glass
very good
👍👍👍👍👍👍
Thanks share!
👍L📸i☀️k🪟e♨️!💦
Good Job :)
Thanks :)
You would need a lot of these plumbed together to make any difference in the pool temperature
Great video. Should the water be fed through the pipe slowly? Otherwise how will it have time to heat up?
That is also what I would like to know..A bit unclear that part.
The water will always heat up as solar energy is absorbed. The temperature rise depends on how cool the water water in the pipe is (cold water will absorb more heat than hot water, because the temperature differential between inside and outside is greater). So if you're heating a pool, run water through the heater quickly. It will only heat up slightly each pass through but as it is repeatedly cycled through it will heat more each time
That will heat a whole pool more quickly than passing the water through slowly and getting it really hot, then diluting that tiny bit of hot water in a cold pool.
I.e. Run the water quickly. Cold water in the pipe will pick up more heat than water which is already hot.
The only problem is with this method is as soon as you turn the water pressure up you lose the heat, the water flow has to be really slow for water to be hot
Será q é 50m ou 100m de mangueira?
