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.
why would i heat watter in pool when its hot outside in summer and if you want to swim in winter this window can not heat up enough wholle pool, maybe outside warm jakuzzi...
Паралельность труб , холодной и гарячей, тем более соприкосновение снижает производительность на 25%-- 30%.
ta hadica nevydrzi teplotu 100 stupnov co tam moze kludne byt
Je to napojené na bazén cez pieskovú filtráciu 3m3/h ktorá je ovládaná cez časovač v rozmedzí 8:00 až 20:00 ,tak že teplota vody v hadici pri takejto vysokej cirkulácii nepresiahne ani 40 stupnov
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
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
What's with the music?
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.
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
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
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.
What's the super annoying music adding to your great project? Spoils the acceptance big time, sorry
I've watched a number of these 'DIY heater' videos looking at what's good and what's not before I design and build my own for heating my hot tub (and a video of course). I also look through the comments. What amazes me the most is the utter lack of understanding of the Physics at work here amongst the general population. Were all these people bunking off school from physics lessons or are our Western education systems really this bad?
The two most common misconceptions I observe being: 1. you gotta "paint it black" and 2. turn the flow rate down or the water won't heat up!
Can you please enlighten us to the essential details to improve efficiency of these things? What is a good flow rate in GPM? Should hoses be left exposed?
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!
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.
how much hot water can you produce with this per minute/hour? and temperatures?
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 ?
How about adding some vegetable oil to the chamber so heat evenly distribute for all sides of the pipe and also trapping the heat itself without losing any to the air?
Actually, the effeciency can be increased by creating a vacuum (or just lowering the pressure) inside the unit rather than adding any other material.
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.
🤔 Plus efficacité si le circuit était métallique et votre 2 eme vitre était transparents car une vitre noire ça chauffe mais empêche la lumière de passer et dans ce cas là je ne vois pas l intérêt de peintre en noire l intérieur.
De plus la deuxième vitre n’a aucun effet , une plaque isolante aurait été mieux pour garder la chaleur
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.
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'
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.
I use a 90mm pvc sewer pipe [holds 20 liters ] painted black and the water gets too hot to use in the middle of the day
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
Hi I am looking into heating my pool. Between the polycarbonate and the black pipe which one would you recommend?
Would it not have been more efficient either to paint the top surface matt black, or leave clear to allow heat to pass through glass with less attenuation?
The glass side he used actually blocks heat. What you are supposed to do is to get a square or rectangle uv double pained window; Heck, even a triangle-shaped one. Then you do what he did, except you flip the top glass putting the uv protection facing inward. This way light goes in and helps with insulation by reflecting light that went through, hit the back, and bounced back up. The bounced back up light hits the UV and bounces back down.
Its much easier to use old waterradiators and skip the whole tiresome building process - You only need to spray them black!!!!
Tried this once . In summer pipe melt and explode. Use copper pipes and paint black instead
No it didnt
Любые шланги взорвутся , если не будет циркуляции воды ..
Sweet heater. the video gave me anxiety
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.
Надо же додуматься в окно вставить! О голова!
Hello, excellent work, just one question, how many feet of hose did you use in the video, greetings and congratulations.
bonjour;tu est un exellent bricoleur ;là y as pas photo;par contre au niveau technique là ;y as des progrés à faire;il te faut le double de tyaux pour doubler le débit sans doubler le diametre des tuyaux;et le plus grave ;et là tu peux me croire si tu veux;le font doit etre en alluminium froissé;et la vitre de réception ne doit surtout pas etre opacivié par quelque peinture que ce soit;les rayon doivent atteindre le cerpentin ;de plus c'est uniquement ton serpentin qui doit etre noir(moi je prefere gris foncé) ha et pour un meilleur rendement ;utilise du tube de cuivre recuit;mais bon il faut un commençement à tout;moi je fait de l'eau chaude avec du fumier (2 mois de chauffage jours et nuit et apres c'est du composte pour le jardin)
Выкинь за тонированное стекло поставь обычная она нижняя наклей светоотражающую плёнку и вода нагреется в два раза быстрее
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.
EXCELENTE TRABAJO FELICIDADES
BENDICIONES PARA TODOS
Non c'è niente di nuovo, esiste già questo tipo di pannello scalda acqua, ma con serpentina di rame, che è sicuramente più professionale,
Good quality! What kind of pump do you use to moving the water? How loud is it? Thanks for your answer in advance.
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
Always cut away from you with a razor knife speaking from experience
Nice design, very neat. Hook it up to a water butt and solar powered pump.
Grande idea!!! Funziona
Yeah, but try to put it on a pool with a flow at 2 or 3000 litres an hour. It gives nothing or so little that its not worth the effort.
Thanks share!
👍L📸i☀️k🪟e♨️!💦
It has got low efficiency. 🙄
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.
Great project but I am surprised that both glass are black. Should the one facing the sun not be clear to allow transmission into the black interior??
My question as well. Both pieces of glass painted black? Doesn't this mean the sun isn't directly heating the tubing of the back glass (to direct sunlight), just the air around it? If so, does it matter what color anything is on the inside?
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.
I had this idea meny years ago but I haven't an hause still now ⁉️🙄😭
Very Thanks for good idea. As i undestood 16 C befor and 46 C after heating. But what is temperature of air ?
Guten Abend ich habe eine Frage, ist die obere Glasscheibe auch von innen mit schwarzer Farben besprüht worden?? Auf dem Video sieht es so aus. Bitte mal kurz Bescheid geben, MfG Danke in voraus.
EXCELLENT WORK! QUALITY AND FINISH IS INDUSTRIAL GRADE!
мужик явно не в себе надо было медную трубу кпд будет выше ))))
yes, if you trickle the water through the hose i'm sure it gets very hot
just watched a video of geothermal system. He could add a set of these to make his system even more efficient!
showing only the temperature is not relevant, you have very little flow. Double the flow and the temp difference drops to half.
He can effectivly accumulate 1kW with this 1m² big heating area.
@@RawData i dunno if you guys think about this... but.. if it were possible to make perfect insulation so that no heat could ever escape. This item could get hotter and hotter forever. Assuming you could also stop the whole thing from melting or catching on fire.
If we come back to the realm of reality. We could do a reasonable job of insulation, and you could probably get something up to around 350 degrees Fehr.. or 176 degrees celcius. Of course as soon as you use the heat for heating something, or if you use it to do work.. it will cool to some extent based on how fast your system can replenish the heat.
Anyway.. these thoughts are interesting to me.. hope to u also.
Your right , If you read the store bought pool solar panels manual The idea is to use high flow with a lower temperature going into the pool. they also recomend 5-10 panels depending on the size of pool. if your pool is 72 degrees and the output is 78 degrees but at a high flow that will eventually heat the pool to 78 now you have 78 being heated to 82 degrees. These you tubers are wrongfully concerned with high temps, they need to be concerned with flow and you also need a lot of panels. this solar panel is very efficient . I hope to make about 8 of these. Not sure about how to combine them efficiently.
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
WOW I need one of this heater on my roof for the all house.
таким слабым потоком бассейн не прогреть!
Don't cover the collector. It's a myth! For pool collectors where the pool water is about the same or typically lower than the roof temperature, such glazing insulation will actually prevent warm roof air from transferring to the pipes, but secondly about 10-15% of sunlight is reflected back into space by the surface of any glazing material. So you lose that much straight off the bat and then there are the potential overheating issues. Keep it simple don't glaze it, you'll get a better result.
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.

I am curious to see how pass the sun throw the colored glass
Génial, ça réchauffe une carafe d'eau en 2 minutes...
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
Plastik has a bad warmth-conductance - better take aluminium or silicon . Also the glass isolates : better fill the window with silicon gel..

Hello, I am writing from Turkey. I'm asking you, is the pipe you are using a specially insulated pipe or a pipe used for normal irrigation?
Are both sides of glas are black ? i mean...the glass on which the snake is lying is black and the glads on top too?
Sollen wir Fenster putzen lernen diese Zeitverschwendung kann man weglassen
Сэр ,Kukomio ! Вместо монотонной музыки , лучше сопровождать видео краткими комментариями !
Wouldn't running cold and tubes next to each other reduce efficiency?
It is better to take one end from inside the spirsl and another from outside.
Woooo, eso me preguntaba yo !! Si se podría poner cristal y luego la manguera !! Muchas gracias !! Excelente video!!
I wonder if it would get even hotter with deep matt black paint layer
Matt black compared to gloss black does get hotter, the gloss is reflective losing energy matte black is absorbing more energy.
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.
Pity this isn't warming up enough to be legionella proof (65ºC). I guess you could win some extra heat if you would insulate the back instead of just painting the glass black.
I'd like to see how much the temperature rises with a normal flow instead of that half full flow you show at the end of the video.
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 .

some techmical data of interest, such as how many degrees in how many days would be its improvement in temperature of how much volume of water ?
What about storage for hot water?
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
How much drip line did you use?
Cuantos metros de manguera negra uso?
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 !
bonjour monsieur vous utilizer como pinture merci
Did you connect the heater directly to the pool pump?
Sont bon nos français 🇫🇷
Para que quiero agua caliente en varano.
Very good system. I will make a similar one. What is the glue/mastic that you use to hold the hose on the glass ?
great caulk hander
Excelente idea pero ya ay una nueva presentación de manguera de silicona y funciona estupendo
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.
bueno el principio es lógico ,pero es muy poca el agua de salida ,si la deja correr como al principio tendríamos que ver en que temperatura real queda ,desde mi punto de vista por ejemplo para calentar 10 grados una piscina de 60.000 litros se necesitaría unos 15 rollos conectados en paralelo a un caño negro de dos pulgadas ,también tendría que tener válvulas de presión para el vapor ,termostato válvulas solenoide mas bomba se agua etc y.... sol jejeje
Ja też mam pytanie jaka była zastosowana pompa i z jaką przepustowością pompowała wodę oraz jaka grubość wężownicy? i czy przy ciągłej pracy pompy, zakładając oczywiście, że jest piękna pogoda dogrzewa wodę cały czas do takiej samej tempetarury?
Długość rury 35 metrów, grubość 16 mm - objętość 7 litrów. Używam pompy z basenu - jest to filtracja piaskowa Marimex ProStar 2 (2 m3/h). Woda w basenie o pojemności 5 m3 podgrzewa z 25 stopni na 30 stopni w ciągu 5 godzin (9:00-14:00)
Wirklich tolle Idee. Super umgesetzt. Darf man fragen wieviel Wasser im Pool sie erhitzen!? Also qm³ in zeit und Temperatur unterschied. Wie verhält sich das im Winter, lassen sie das Wasser ab oder bleibt es drin!? LG Grüße
