How to make a pool heater under $100

[@BRI33NOR]

I worked on a campground in Scotland. The pool was heated by passing water from the pool through two metal household radiator units. These were situated in a small purpose built glasshouse. The whole heating surfaces were painted Matt black to absorb more heat. The supply pipes were insulated to prevent heat loss. The whole set up was quite simple. It was very efficient indeed even with moderate sunlight, extended the usable period of the pool considerably. Cost was virtually nothing. Brian Williamson.

I did a similar experiment 10 years ago in southern Arizona under full sun. The water going in was 80 degrees and the water coming out was over 110 degrees. Flow rate appeared about the same but I didn't measure it. However, in a 15,000 gallon pool the amount of heat gained didn't compensate for the heat loss overnight. After many experiments with black irrigation tubing and several hundred dollars in costs, including getting a used Fafco 4'x8' solar panel to test, I tried a solar blanket. Like day and night. A solar blanket is a thousand times more cost effective. It doesn't so much heat the pool as it keep evaporation from cooling the pool, day or night. Even during our high humidity rainy season it prevented heat loss partly due to evaporation but also due to insulation (reducing radiation, conduction and convection heat loss). That being said, I once tested using heating coils and using a pool blanket in the middle of summer (100 degree highs are not uncommon in the summer here). Pool was a little over 80 in the morning after cooling down overnight. It was a full sunny day with no clouds. When I got home the pool was 105 degrees! I had a pool sized hot tub! If I had just used the coils the temp would have been around 90, without the coils the pool temp would have been around 87. So my testing, 192 sq ft of coils and connectors (I have a hose bib on my pool pump so I didn't need to buy a sump) overall costing about $300 and passing through it what appeared to be about the same GPM as you have in your video will raise my pool temp 3-4 degrees above what it would have risen without it. It looses all the heat overnight and has to heat it again the next day to the same temp. Compare to a $100 solar pool blanket which cuts heat loss due to evaporation overnight and during the day. The first day gets you about 2-3 degrees warmer simply from blocking evaporation, so the first day is not as good as the solar coils. However, the second day starts you off 4-6 degrees warmer than it otherwise would have been without the blanket and you get another 2-3 more degrees heating that day for a total of 6-9 degrees over what it would have been without the solar blanket. The efficiency starts dropping at that point, but you get far better results for your dollar with a solar blanket. -- The disadvantages of a solar blanket are that you have to keep the pH above 1.2 and the Chlorine below 3 ppm (removing it to shock) otherwise the plastic will degrade and you will end up with tiny popped plastic bubbles floating around your pool and clogging the filter. No solar blanket warranty covers broken bubbles. But if you have a salt water chlorine generator it will be very easy to maintain these levels since it is constantly raising pH and can be set at a lower generation rate (as you will also need less chlorine while using a solar blanket). HINT: Use a SCH 40 PVC pipe capped at both ends (so it's airtight and will float) and slide it under the middle of the solar blanket (short way, not long way) and you can easily lift off and roll up the blanket if you have someone helping from the other end. I hope this is helpful to someone.

Very helpful thanks

[@TheFailroad]

It's all true. Solar blanket makes a big difference. I had good results with the cheap intex solar mats. Link 3 or 4 of them with a solar cover and you're good to go. My small pool will easily go up 10F+

[@roycerichardsphoto]

Thank you brother. I really appreciate this information. My backyard is shady ass all get out thanks to my neighbors MASSIVE trees. It's a blessing and a curse. The pool is not hot enough to swim in on most days. The water is usually around 72-76 degrees. I have never seen it go above 83. I'll give your recommendation a shot. I live in PA by the way. Thanks again.

[@badmandansanchez1823]

In planning stages for a similar project also in southern AZ. You are correct evaporation certainly cools the water and in Tucson we lose 100" a year. At certain points of the year that's an inch a day. I have dogs so blankets are a no go for fear of them drowning. I'm thinking 500' tube, pond pump and a solar panel I already have. The warmer the water the more chlorine, but I made a solar copper ionization thing that seems to be working great so not too worried about that. My biggest concern is finding the right pump that will carry the water to the roof but be slow enough flow for the water to heat up.

[@Dennyh025]

@@roycerichardsphoto I live in PA also, my parents don't live too far from me, maybe 15 miles, and my mom has a pool and I was looking for DIY ways to heat her pool. She does have a solar cover, but I wanted to be able to try something more. It's been a crazy year for temps in PA this year, yesterday it was sunny and only in the mid to upper 60s, then this morning it actually got down to 32 degrees. I live in north, northwestern la right near the PA/NY border.

[@franklinwilson3783]

I live in Michigan ...I have a 24x52 round above ground pool. I made a similar system to this but with a few differences. I built a wooden tray and lined it with black plastic for better sun absorption as well as insulation. On top of that I put a 600 watt plant warming mat then I put 100 ft. of coiled 1/2 in. black poly tubing on top of that and covered that whole thing with more 6 mil black plastic for even more sun absorption and added insulation for heat retention. I used a 1000 GPH fountain pump to push the water through the tubing. Before I started my unheated pool water was a rather chilly 68 degrees. After using my home made solar heater as well as my 8 mil solar cover I can keep my pool water just over 80 degrees consistently, even with night time air temps of 50 degrees. The solar cover is vital to maintaining, and insulating the warmth in the pool. Without it I lose any temperature gain from my DIY solar heater, and the solar cover also adds warmth as well. The whole thing is about 3ft by 3ft. and I have it stashed on an inconspicuous sunny side of the pool. I also put the whole thing on legs about 3 ft. high to keep the cold ground from cooling off the tubing. Obviously this is not nearly as efficient as a gas heater but it does give us about an extra 2 weeks in the spring and 2 weeks in the fall that we didnt have previously. The whole thing including solar cover cost me under 150 bucks . I only use it in mid May till mid June and then again in MId August till mid Sept. Then I close it down for the winter.

[@praveenchawla6999]

Great comment, Franklin. How is the system going? Can you post some pictures of your system?

[@JoeLampshire74]

Franklin Wilson any pictures please mate

[@SaintBrook]

By my calculations, that's a 2.2 kW heater you have there. I live in New Mexico, so we get a lot of sun. I recently made a solar heater like this using 400 feet of garden hose and tubing placed on the roof of my house. I'd prime the whole line with water first so the water coming down would act as a siphon for the water going up so my 1/10 HP transfer pump didn't have to work very hard. I'd get a 15 degree F temperature rise at 1.8 GPM flow rate, which corresponds to 4 kW. Not bad for the 150 W I was using to drive the pump.

[@charliehome9198]

Awesome, Any pictures or videos of your setup?

[@richardmarquez3394]

Smart

[@chrisbowe4238]

I have a 16' round (5000 gal) above ground pool and pretty much did this. 4 - 100ft 1/2" poly tube and submersible pump. Today in Indiana temp is 76* and good sun. I've raised the temp of the water from 69* to 73* in about 4ish hours. The setup is pushing out close to +5* difference from ambient temp of water. Is it pretty? No. Does it work? YES. Way better than the 2 dome solar heater setup I did a few years ago.

[@crazykuup9271]

That’s a great setup!!!!! I seen a guy that put the pipe on his roof and buried the line to the pool so no one even saw!

[@fidelcarter9162]

Really cool. Thank you. Maybe You're losing heat from the stone on the pool deck. Maybe a stand or foil wrap might increase the temp

[@Happiwappi]

i'm not sure but i think that if you put the coils in series instead of parrallel it would work better because the water would run trough more tube so it would have more time to heat up.

[@user-mj9im5lt8z]

Actually that is not true. Heat will transfer faster to the pipe when the temperature of the water is colder (Heat Transfer 101), also the flow rate is reduced. So with a parallel connection you get more heat from the sun into the pool even though the water comes out cooler.

[@LeSa97SaLe]

The best combination is to make few of these to rise the temperature, and then cover it with solar blanket, and you'll have such a huge difference

[@chalmrast]

I have a 20,000 gallon pool with a 400,000 BTU gas heater. Takes about 6-7 hours to heat it up 10 degrees. This is a clever idea but the delta T (difference in water temp entering and leaving the system) is much too low and the flow rate is much too low. You have a very large pool with a lot of surface area and you will never over come the losses from the outside air and evaporation. It takes 1 BTU to raise 1lb of water 1 degree F. You are pumping (5 gal/min * 8.34 lbs/gal * 60min/hr) = 2,502 lbs per hour and raising it 4.7 degrees which is about 12,000 BTU/hr. With a perfectly insulated system (no heat loss) and an estimated volume of your pool of 40K gallons it will take 27 hours in the sun to raise the temperature 1 def F

[@emailjwr]

This guy gets it. Thanks for saving me doing the calculations. These systems don't with for anyone unless the pool is very small.

[@milleniumann28]

Yes this is correct! The amount of water leaving his return is doing nothing. I've tried this, solar blanket, small heat pump and after all that wasted money I could have purchased a 180k btu heat pump and been done with it. You must have return flow heated at desired temp let's say 80 degrees to even make a difference on my 20k pool. I'm not a math genius but common sense tells me pump flow at 80 degrees is better than 2 gallon per hour dribbling out at 180 degrees. Not to mention spring and fall where I'm at gets into 50s and 60's so heat loss will happen no matter what cover or not. One cold night could kill a week's worth of solar heat its like pissin in the wind with the diy solar heater. Next year I will take this advice and get a nice sized heat pump or gas heater it's the only way to go if your serious about heating the pool.

[@tomn5880]

We made a heater by using a 55 gallon drum and placing a 30 drum can inside. We filled the space between the two with a copper coil and sand then built a fire using fireplace wood. We used a bilge pump for the circulation pump and achieved 110 F @ 4 GPM. Took a while to heat the 19 foot round pool but it worked.

[@adjuster57]

Pool cover!! More effective, and less of a headache.

[@rugvedkulkarni1593]

How does it work? Won't a cover just prevent sunlight from hitting the water?

[@crypto6347]

it works best when enclosing with glass or plexiglass.you get 5 to 10 degree!

[@forjoining1]

you should connect the coils of hoses in one continuous flow, and not using T's to branch off each coil. You should get more efficient distribution, better heating.

[@notawinemom8540]

That is the most beautiful backyard I have ever seen!

[@Livedan330]

[@AnN-tv4hv]

Pretty cool! 800 ft ~$96 It should be warmer if you place on your roof on something black. It is probably better to elevate it above the ground as it might lose some heat warming the white stones around the pool. Do you if those hoses release some chemicals when heated?

[@dougschust1]

I love this! At first I wasn't sure

[@KarlH1980]

I have to chime in with the other comments. This is a half done project. Measuring the temperature of the water coming out of the tube is like stopping sex in the middle of it. You ain't done!! How much does the T of the water increase over a period of time, 24 hours, 7 days, etc... Increasing the T of ~1% of the water by 7 degrees is unlikely to result in measurable increase in entire body of water. [EDIT] I just did the math. A pool that size depending on the environment should be using a heater with a BTU rating between 80,000 and 110,000. The system you've described generates 453. If I've done the math right, that's 0.3% - 0.6% of the needed energy.

[@Think-dont-believe]

🤣😂🤣😂🤣😂

[@MsScruffy4]

But how much did the pool itself heat up? Kind of the point. At least put the intake on the other end?? Might work on a sunny day with a timer to allow the water to sit in the hose 20 min and then dump.

[@Bar9roy9]

[@joebenforte5184]

I see a few issues. 1 it's hard to tell if you are measuring the temp of the water or touching the side of the piping which would be considerably warmer. 2. That little amount of water leaving the hose is neglible compared to the remaining amount of water in the pool that is cooling down at the same time. This would likely make a significant impact with a solar blanket though. The other thing is to remember to shut it off at night when it would be cooler out than inside the pool.

[@boherrmannsen8219]

could be fun to know if you can predict when the pool will be at a given temp if you know the flowrate and the inlet and outlet temp of the heater coil or a solar heater mat

[@bullionhomeinspections2473]

Put the coils on your roof and you will get a lot more heat.

[@SahilMalik]

This is great, but you have to keep the pool open (i.e. evaporation loss). Just cover it with a cover, and let the sun bake it. Wouldn't that be better? Of course a system that allows you to have both a solar pool heater and a cover would be the best.

You need an exchange rate of running the whole volume of tour pool in 8 hours. If you are running 5 degrees higher you would increase the pool temp by that much. Need to generate more heat for it to work. Good idea but with an in ground pool you have a lot of water.

You do not want to use poly tubing for a pool because chlorine will destroy it over time. Instead, get black flexible PVC pipe.

... the trickle coming from that pipe would lose half its heat into the air within a few seconds of it hitting the water... if u have a spa, I guess this would work alright, but if u have a 30,000L pool, this method would surely take days to actually make a noticable difference... And theres no way I'd manage to buy all of those pipes for 100 dollars. The other issue is that if you have cold weather, this isn't going to do jack shit, cos all the heat from the sun would be lost straight away to the air convection... Most people want a heater for when they have cold weather. so I don't see the point.

[@rronmar]

Solar 101: to maximize output, reduce losses... put the coils on something insulated, preferably black. Cover them with clear plastic, sealed to trap some air for insulation. 200 GPH at 5 deg F temp rise is about 8000 btu/hr, or about the same amount of energy contained in 1lb of wood pellets How many gallons is that pool?...

I cannot figure out why I am the first that I see saying this .. but buddy you need to measure the pool temp away from where the water is re entering the pool. You are measuring water that is basically the temp of the heated water. This is why so many people are giving you shit about the small gains. Your pool water measured at the opposite end of the pool from your heated water, would most likely be closer to 60 degrees.

[@leslieb6881]

Being a pool owner, I thought the same thing.

[@stewtheman]

Let’s go with your figures that you can get a 7 degree rise out of this setup at 3 gallons per minute for 8 hours a day. Let’s also assume your pool is 15,000 gallons. That setup will heat the pool by 2/3 of a degree over the course of the day (3 gallons x 60 minutes x 8 hours x 7 degrees = 10,080 gallons / 15,000 gallons = 2/3 of a degree of heat). This is a lot of work for something that doesn’t actually work. And anyone who’s paid attention to their pool temps knows that a pool will naturally gain several degrees of heat on a warm, sunny day. I monitored my pool yesterday and it went from 81 degrees at 10:00 AM to 86 degrees at 4:00 PM all by itself! And this is in Ohio. Let’s look at the math of that a little: (6 hours vs. 8 hours, 2/3 of a degree vs. 5 degrees) .67 degrees x .75 time = .5 degrees in 6 hours with this system vs. 5 degrees in 6 hours from the sun alone. For me, the sun was literally 10 times more efficient all by itself than this system. You’d be much better served keeping a solar cover on the pool at night so that the water can retain the heat it gained during the day. The other issue is the pump required to pump 3 gallons a minute through 800 feet of hose. That thing has to be using a fair amount of energy to accomplish that. That energy isn’t free. It’s a little ridiculous that you’re presenting this system as successful without showing any meaningful results. The purpose is to heat the pool and you have not done that. The figures you mentioned make for some very easy math that demonstrates that this idea will not work (as I demonstrated above). If your pool gets up to your desired temperature, it will be doing so in spite of your system. Also, this isn’t under $100. I’m using a tankless water heater that cost $80 and I could make the same deceitful claim. But why would I do that? I’m also using a pump, a thermostat and some other things that put the price at $200. But it also actually heats my pool and can be scheduled to maintain a specific temperature.

[@williambrennan5701]

That system would do little to nothing. I have 160ft of solar pool heater on top of a south facing metal roof that gets 8 plus hours of sun per day even in winter in North Florida. If i TURN the flow rate up to max My flow rate is just under 10 gallons per minute and the water coming out of the heater is 10 degrees hotter than what went into it. I run the pump every day for 8 hours a day during the hottest part of the day. Assuming mostly full sunlight heating an above ground 24 ft round pool. i can keep the pools temperature at whatever the day time high temp is . For example if the daytime high is 90 then my pool will be 90 by about 2 pm every day. But when it gets into the 50's thats all i can heat it up too. That pool heater shown in the video with half the flow rate of mine and only 1/5th the temp rise would be useless especially on a pool that size. Just go buy a real solar heater, check craigslist i paid 40 dollars for both of mine that are 4 ft wide 20 ft long cause it had a leak that cost 10 cent to fix. Also even though THEY ARE black plastic , black plastic fades to grey paint it black again every couple of years, i gained 1 degree doing that!

3 watts (or about 1/20th of what you can steal from your phone jack) can power a 70 gallon per hour pump, or 14 Watts (slightly more than an 11 watt modern light bulb) can pump 200 gallons per hour. I'd go for the 14 watts. It would take a few days to a week to jack up your pool by 10 degrees.

[@doubleclutchonline5811]

My dad, an engineer, always said he wanted to build me this type of system so that I don't waste tons of propane heating my pool. Though the water appears to only become lukewarm through this system, and not enough to be substantial. I wonder what the benefit would be if a system like this was used in conjunction with a conventional pool heater? Even if a solar setup helped keep the water a couple degrees warmer so that the propane heater could work less, I guess it might be worth it.

[@Livedan330]

Exactly. We did notice a difference when we used it. Save some money. Fun project. Scale it how you want. It was a proof of concept.

[@iggyarctic5711]

This video appears to be a joke ? Are you adding additional water from your faucet (much higher water bill) or are you connecting your black hose to the pool equipment,using the water already in the pool?

[@natileekittentop2841]

No this is not a joke, you place one end of the black hose up into the end of the water coming out of the water filter/pump. That will push the water into the hose system that will inreturn end up running back into your pool but much warmer. It is very effective and easy especially on a warm sunny day! The water coming out could be up to 100-120. Depending on how hot of a day it is.

[@guciochris5297]

You just increased the pool by 4 square meters. WOW !!! how about use dark tiles?????

How warm is the bottom of the pool. This sucks

I made it by myself. I used Avasva solutions for that.

What's Avasva please ? Thanks, Gerry from Cali

66 - 68 degrees is perfect. Why spoil it by making it hotter? Hot pools are more difficult to maintain.

Good point! Maybe a cheap wetsuit will do the trick also

Losing lots of heat by having it on the cold stone. You're heating the stone also. OT: Why would you want your .com on the bottom of your pool so people can find your house?

dude if u r worried about 4degree difference in ur pool, then u should fill ur pool in with dirt.

[@Baer1990]

Impressive, but not warm enough on a shady day

[@JoseJimenez-vw2cw]

so you bought one half inch poly pipe but its looks like half inch to me ! !

[@dudndadn12212]

This will literally do nothing to heat your pool up. The sun blasting it will heat it way more than this. Also solar cover. They are heat but they work.

[@endlessadventure541]

This video is insane. Where is the before and after POOL temperature? Are you really going to swim in a 70 degree pool? Are you nuts? You need to really calculate your water displacement based upon the pool volume and overnight energy loss. I bet that after an entire day you don't raise your pool even 1 degree. Are you planning on swimming in that bucket???

[@nocomment3404]

70° is perfect pool temperature I have to drain water out and refill to lower the temperature when it get too high

[@pumpkin9916]

@@nocomment3404 Olympic standard pool temperatures are 77 to 82 degrees. Water below 77 is considered cold. Below 70 can actually start getting into dangerous levels. So, no, 70 is not at all a good temperature to have. 82 to 85 is warmish. 91 is your skin temperature, usually the most comofortable temperature when you shower.

[@nocomment3404]

Bobbin apple. 77 is way too warm. There is no way I'd be comfortable in there. Like I said I'd have to drain some out I like to keep my pool at 70° maximum. Anything higher and you might as well get a hot tub

[@WVgunfun]

@@pumpkin9916 LOL, olympic standards.....are you having a lot of meets in the backyard? 70 is perfect, the kids love it and it's refreshing, it's not a bath. Cooler pools are easier to maintain also. Do you even have a pool?

[@pumpkin9916]

@@WVgunfun Argue with facts from the National Center of Cold Water Safety. Anything below 70 is not "comfortable." Kids that are actively running around and keeping an increased heart rate should be fine staying warm. I understand you think 70 is warm, but 70 is not what your thinking it is. Ambient air temperature and water temperatures are entirely different things. Water also pulls heat from your body around 25 times faster than air. 70 outside does not equal 70 degrees in water/pool. Yes, i own a pool. I also have a thermometer (something you apparently dont use or know how to read because you think 70 degree water is warm). www.coldwatersafety.org/WhatIsCold.html Edit: Before you read this and start backtracking by saying "oh i never said it was warm," I will instead quote you for saying 70 is "perfect." 70 is extremely far from perfect seeing as how your skin temperature is around 91 degrees and anything less over long periods of time can and will eventually lead to death. Way to go!

A black pool blanket is way more efficient and cheaper.

what about just painting the whole pool in black? or using black tiles for the entire pool..?

Its always good to be frugal and save when you can, then when he has some gs saved up he can get a proper one. Very inovative idea for cheaper :)
