  • Todays video is How to Build a DIY Pool Heater for Any Size Pool - Why All My Other Pool Heaters Failed!!!
    This is my 3rd design and my favorite so far for my DIY Pool Heater Ideas. This Pool Heater design is perfect for anyone / any pool. All you need to do is build be more less of them for your pool size. Each one is 200 feet of tubing. I designed these to heat water much slower than the previous pool heaters and ensured that this pool heater had the proper support to stand up to the California Sun.

    I was a little concerned about the mixed reviews, but I used it last year and hooked it up again this year and it was great czcams.com/users/postUgkx-izdrK3eF-HMvjzeBOxToD6Fx-4ulJUh . I couldn't get my 10' Intex pool above 76 degrees the year prior and last year I got it to 90 and had to put ice in it. This worked so well! I have just 1 mat hooked up to a 1,000 GPH Intex pump and it makes a significant reduction in the flow rate coming back into the pool, but that is to be expected with how far the water has to travel through the mat.

    For 20 years we had a large oval above ground pool in Michigan. We used 3 commercial pool heat panels 4x20 ft on a ground mounted platform. The design of the panels was such that you could easily run them in series but the dealer suggested not to do that as it increases the load on the pump and lowers the flow rate. So we used a custom manifold to connect the three panels in parallel. We also used a separate pump to run just the solar heater so we could run it whenever we wanted and it was 1/3 the electric use of the primary pump. I built a simple Arduino controller that ran the pump only when the pool was below our preferred temp and the solar panel was at least 5 degrees above that. In full sun the water coming back into the pool was about 10 degrees higher than the pool through a 1.5" pipe at full flow, so that's a lot of BTU! To prevent cycling I also set a minimum cycle time of 5 min either off or on though this rarely was an issue. This was a set it and forget it solution for the entire summer and the pool was always nearly the perfect temperature.

    Nice video but a recommendation... I don't think you should be trying to throttle flow based on temperature. It's all about the BTUs going into the system from the sun. That doesn't change so it doesn't matter if you are flowing 1 gpm and getting 150 degree water or flowing 20 gpm and seeing a 2 degree temperature rise because the BTU heating into the pool is the same. The difference is in where you mention you keep the polycarbonate off the roof because it gets too hot. You are actually allowing BTUs to "escape" by doing this and thus not putting those BTUs into your pool. You'll be far far better off in this case to keep the poly ON but keeping flowrate HIGH to keep the temperature down so it doesn't melt your piping. Doing that will put more BTUs into your pool. Anyway, just wanted to point out that the temperature on your outlet pipe doesn't matter... it's the BTU input. :)

      Somebody needs to manufacture a coil through some molding process where each coil shares a common wall. This would reduce material by at least 25 - 40% and you wouldn’t have to spend all that time wrangling tubing into a circle. You could even design it with 90 degree corners to fit well in an enclosure, even though the fluid passages maintained a radius for good flow that took advantage of the wasted corner spaces to improve efficiency. The model could be scaled in any ID tubing, and rectangular shapes for different installations. You could use extruded Aluminum with 90 degree corners like a screen is made for site assembly. The extrusions could have mounting tabs that align with holes in the molded flow tubing. Maybe someone already makes something like that, or there really isn’t any demand. Just seems like a good idea…

    This is a great video. However the times have changed in favor of the products in today's given time. Instead of doing solar paneling and having to wait till the sun can generate enough heat to get hot water to the pool. I opted for a 8 gallon electric tankless water heater. I wanted the ability to have on demand hot water at well and not wait for the sun and what if overcasting was an issue. But after 1 hour of installation with a water transfer pump two hoses I now get 150° of water at will. I also bought a digital timer so that way The tankless water runs 15 minute intervals and turns off 1 to 2 minutes and restarts again. I could have went with solar and was about to do so but by the time I would have calculated all the pieces needed for an extra $100 I decided to splurge with the tankless water heater, it's just the options today you don't have to work as hard using solar. Not saying solar is not a good solution it is for those who get plenty of sun.

  • @eCitizen1
    @eCitizen1 Před 10 měsíci +4

    Here are a few suggestions for making your solar heater system better, safer and more efficient.
    #1 Get a water pump dedicated to supplying your solar heater system. A "hot water recirculating pump" would be ideally suited for this.This will also negate the need for any valve or valve adjustment between the inlet and outlet of your solar heater, and unburden your main pool pump from pushing water up to the solar heater.
    #2 Use a temperature controller to activate your solar water pump whenever the temperature in your solar panel is above 100 degrees.
    This will automate the fill and flow process and protect your solar panel from overheating, melting and from operating when cold.
    #3 Setup a manual override to force the solar pump on during testing.
    #4 Use solenoids to allow filling and draining of your solar heater. Empty when not used and freeze protection.(need separate drain)
    #5 Add an enable switch and temperature controller for your fill and drain solenoids, also with a manual override for testing.
    (note" #2 would be enabled by #5 if you use solenoids)
    I hope this gives you some food for thought and helps you to upgrade your system.

    I was on a building job back in 91 in the UK and the owner had a pool with a black hose pipe going all around the edge, probably 10-20 times to heat the water. It was great to take a dip on a hot sunny day but one day we weren't told the pump had been switched of and the temp had got down about 10 degrees so we had a shock when we jumped in!🥶

  • @swingman141414

    As someone who has done these for pools myself, I recommend keeping your plumbing at 2 inch. Then restrict the 2 inch pipe on the roof down to your 3 heating coils, then back to 2 inch going back down to the original plumbing, this will help to make sure your pressure does not spike, it will also move the water much quicker through your system so it doesn't melt your system. And also you won't have to use a ball valve to force it. You can shut the ball valve off completely and the flow and pressure would stay the same. Also of you're going to keep the roof seal with the plexiglass, I recommend you find a way to vent it. That heat held in like that drives the air temp up to 250-300° in the summer time.

      Yes, I agree with this theoretical plan. The rate of flow is critical to success and the weakness of these long tube systems is in their rate of flow. Thank you very much for the video, all of the difficult work that was put into designing and building these systems from plastic. Your timing is good.
      I’m in the middle of building a system using copper. this is my second system with copper. The first one lasted 41 years. It is expensive compared to plastic, but reportedly it is 60% more efficient and it certainly does last.
      I am installing two sets of four panels. The Total is just under 300 ft.² with a 3/8 inch copper tube every four inches. 96 tubes v. 3. The pool surface is about 800 Square feet. So maybe my new system is a little undersized.

    Lots of good info and learning from experience in the video and in the comments.
    I'd make the spirals with the send and return lines paired, with a U bend in the centre. Lines could enter/exit together or on opposite edges. This way the spiral can stay flat without overlaps.
    Slow flow is great if you want to make a cup of coffee, heat radiators for the house or do the washing up, but high flow within reason is best for getting energy out of the system.
    Of course, running at a high flow rate uses peak rate energy so a trade off is needed. A couple of solar panels could do this as it only needs to pump when the sun is up.

  • @GramSchweikert
    @GramSchweikert Před rokem +6

    You clearly don't understand thermodynamics but decent build. Increase flow through heaters to increase heat into the pool. This will also keep the heaters cooler which will make the plastics happier. Also think about thermal expansion., Slowing the pipes to move as they heat up and get longer.

  • @Dem0n1337

    So, there are a few reasons your other attempts failed actually. The first is going to be water flow. I come from the PC liquid cooling space personally and this is something we pay attention to quite alot. You need more flow through the black tubing. Doing this will mean that the tubing can only get so hot at any given time but still give a great chance to let the water heat up. This is due to the fact that water will pull a ton of heat out of the tubing. The more flow the better. The second is already mentioned in another comment. Putting the plexiglass over the top will drive the temps way high. Which is good to some degree but partnered with the problem of not enough flow this will instantly start melting pipe. So instead you should have some sort of venting mechanism. It doesn't have to be much but just enough. If you even did something as simple as putting venting holes in the side of the case it would be enough. So first increase the flow through the tube, ideally all of your water flow through that tube for best results. Next, the venting. If you do both of these you won't have any issues.
    Think of this like the balloon with water in it. If you put water in a balloon and hold a lighter to it, it doesnt pop. Because the water is keeping the temperature under control.

  • @Solar750
    @Solar750 Před 11 měsíci +3

    Great Vid, I appreciate all the attempts, as I've been doing similar things. One thing to keep in mind is that the goal is not to get the water as hot as possible, its to get as much heat into the pool. You slowed the flow several times to show increases temp, but that is also what's making your other attempts fail. Said another way, a small amount of super hot water is not better than a large amount of slightly hotter water. The thermal dynamics are the same in the main body of water. Increase your flow as much as possible to protect the heater. You won't gain anything by slowing it down. I've had several attempts fail with the "Sprinkler Hose" for too. It just isn't made for this kind of heat. Pex hose or garden hose allow much more flow, and have higher temp ratings if you have to try again.

  • @karlbridger4110
    @karlbridger4110 Před rokem +15

    Since you're more interested in the pool temperature and not the temperature of the water coming out the heater - you should have the flow as high as you can. This will give the best thermal transfer ability and heat the pool more.

    • @jamesmcdaniel2132
      @jamesmcdaniel2132 Před rokem +1

      This is correct temperature differential is what you want but slowing the flow through the solar panels makes the differential greater in the pipes but slows the heating of the pool water. It is not a big difference in the time it takes to change the temperature of the pool water temperature but your system will run cooler and save on maintenance You should also add a vacuum breaker to the 2" pipe on the roof to drain the system when the pump goes off.

    You mention "shutting off" the heater once the pool is up to desired temperature. The only way to do so would be to cover the collectors. Uncovered with water inside will result in boiling, steam, then rupture. Uncovered with water drained will result in melted tubing and fittings.

  • @Suncoastinc
    @Suncoastinc Před rokem +4

    It appears that if you close the 2 valves on the risers going to the roof, the tubing can get so hot that it creates steam pressure and blows the system apart. It appears that if you left one side a straight flow, excess pressure would transfer to the pool piping and not over pressure the heater coils. Just an explosive thought.

    What I found doing water cooling systems for computers is that the flow is more important than the temperature. Meaning, that if you have like 1 to 2 degrees more on the pipe coming from the heating unit at a higher flow rate it is better than having like 10-20 degrees coming from it at a lower flow rate. Also you do not want to feel like crazy warm temperatures at the outlet in the pool, but slowly increasing the temperature. That way the materials live longer 🙂

    Do you have to stand it up vertically? or have it directly facing the sun? My panel is mounted high up, slightly tilted but tilted toward the pool and not the sun, but it does get full exposure to sunlight. I do notice the water gets way hotter before i mount it up and it was below pool level and standing up leading against the pool.

My new system only increases 1-2 degrees but I’m moving 20,000 gallons a day through it so my pool heats up better than the old one that had 30 degree increase but I could only move 2000 gallons of water through it.

One for the pool water temperature to turn it on when the pool needs heat and one for the temperature at the collector which turns off the flow if the temperature of the collector is not warmer than pool water to prevent the heater from radiating heat from the water and cooling it off. This optimises for cloudy weather and automatically shuts the heater off at night.

    Reading that more flow works better this is my question - I have a roll of "sort of" flexible 1.5" black plastic pool pipe leftover. Would using that larger pipe (with connectors) in the box like a radiator (in at bottom row, out at top row) transfer enough heat? This would keep the entire run at 1.5" like the rest of my inground pool avoiding reductions and pressure changes. This would be connected to pump/return system with valves etc. Any thoughts?

    • @chrisbuildsitall

      It could work, problem with that is that it probably won’t pick up much heat as it moves through the pipe. It’s definitely worth a shot though, even if you can get 1 or 2 degrees increase it would work for the long run I think.

    I appreciated you walking us through the trial-and-error process and the lessons you learned. I believe you used a 5/8" pex pipe. Was it type A or B, and what was the approximate cost? The earlier comment on CPVC not being available in black. Is it materially different based on color? I noticed some others were spray painting the pipe black - suggesting the paint had UV protection while the pipe itself did not. I have a 34,000 gal. pool. I just installed the Hayward 140k heat pump, but I'm afraid to rely on it for all my needs. Electrical costs just took a 40 percent hike here in PA. Any suggestions would be sincerely appreciated.

      I used landscape tubing, probably won’t use again because of how easily it can rupture when hot. I would use pex a since it’s the most flexible type. If you can’t find it in black then you’ll have to paint it black once you’ve built your heater. Guessing your pool is around 20’ wide and 40’ long so you’ll need around 800 feet of tubing, or 4 of these heaters I built. Heat pumps are tough to run if you don’t have solar power. You might look at getting a small array just to power your pool equipment. Then you can run your heat pump all the time and get some good use out of it.

    You don't need to restrict the flow my friend. The more water you flow through the system, the more kilowatts of heat you get out of the collector and into your pool. it doesn't matter if the returned water is not so warm, because the total amount of heat is greater due to the increased water flow. The only limitation is the amount of power you want to consume with your pump.

    You've got your heart in the right place but thinking a little skewed. The macro is capturing the available energy from the sun and not letting it go. Energy transfer is based around, materials conductivity, temperature differential, convection and time. You don't want to lose energy is the missed point, a great way of energy loss is temperature differential, heating the water way up on the roof then passing it through the down pipes, underground plumbing to the pool then the localised surface and pool wall is an easy way to loose heat simply because the high temperature differential. Lifing the temperature slightly over the pool temp is very efficient (not including pumping losses) to minimise temp losses per time. The reverse is working for you on the roof, large temp gradient of the air in the roof boxes by the sun heating and extra cold water throughout the hose loops offers maximum available temp transfer/time. The pool industry sell "solar" blankets and these things work by trapping in the heat or really slowing the losses. Increasing the flow rate to maintain a small temp rise will maximise the energy gain from the sun and minimise the losses in the system.
    If you want an optimised pool setup, an insulated pool shell, a Dark tile or Dark liner pool (they look deeper when dark), insulated plumbing, a pool surround of dark WPC deck that runs water through it (patented) back to the pool, a pool blanket and roof top tubing is the max passive design for heating. Your pool is hotter and gains more usable days while the deck is cool and in winter the deck is warmed by the pool water (that you're not using) so allows for greater deck usage.

    You would have a better, balanced flow to each heater panel if you reversed your heater panel discharge header. You should have first panel in on supply header is the last panel out on the discharge header. Your supply header is panel 1 (tee), panel 2 (tee) and panel 3 (90) (from holes in the roof, near to far). So your supply header should be panel 3 (tee), panel 2 (tee), panel 1 (90) and have it 90 back down through the pool eq house roof near panel 3. Return it to the pump under the roof a/n. Try to keep the total amount of pipe before and after the panels back to the pump room the same length. As you have it piped in this video it's likely one of the panels is carrying more load than the others.
    I agree with another commentator, the total pipe sizing of the panels should be the volume of the pool piping itself 2". Rule of thumb the capacity of a pipe doubles for each regular plumbing line size, 1/2" is half of 3/4" is half of 1" is half of 1.25" is half of 1.5" is half of 2". You can check this by computing the area of the interior diameter of the pipe, (multiply by length for volume). Area of 2" pipe (ID 2.067 for sch 40) = 3.3556 sq in. Area of 5/8" irrigation tube (ID 0.6) = 0.28274 sq in. With three panels you are at 0.28274x3=0.84822. You can make it work but you have to guesstimate how to throttle that ball valve (not made for that use case.) That BV should be replaced with an actual flow control device if you're keeping this set up.
    On version 4, go 4 coils of 1" tube pulling off of 2" headers. First panel in on supply header, is last panel out on return header. If the tubing is rated for the pressure you can leave the ball valve and just shut it when you want to use the heater. Open it, and close the valve on the heater supply side when you don't. Inside the pump room, I'd also put a ball valve just after the tee on the heater supply side and a check valve (you only need one,) then up through the roof.

    You've stumbled onto the main problem of solar water heaters, which is that if the sun is out water NEEDS to flow thru the heater, even if you don't need it heated. This is true for househould solar heaters too, and you need to be able to dump the hot water somewhere even if you don't need it. If the sun is out and water is not flowing temperatures in the system get so high they all get ruined eventually. so keep the pump running if the sun is up (or get a smaller solar pump for that)

      The water would be much warmer that way but you lose 2/3 of your water movement.

    @7:50 You said, you've got 1.25" pipe and three 5/8" hoses that is more than what 1.25" ends up being. This is incorrect. Each "hose" has a cross-section of 0.30679 in^2 totaling 0.92036 in^2. While the cross-section on 1.25" pipe is 1.2271 in^2. You will still have a restriction at your sink-elements.
    Also, because you're using manifold to distribute your water through the three sinks, and each sink as the same size fittings, you will see less flow through the last sink on the manifold. This means the temp will be higher in the last sink compared to 1st.
    I agree with Brent Franker. Adjust the flow for max BTU transfer, not temp delta. This will ensure max heat is being removed from the system. i.e. Protecting all that Polyvinyl chloride :)
    I am surprised that you didn't use CPVC or copper considering your prior experience with overheating the PVC. Painting the PVC is not doing you any favors either. The problems are only going to get worse when you shutoff the water flow because you've reached the desired temp. The pipes are going to cook without the water flowing.
    One last food for thought. If you are not condensing the Freon in your A/C with your pool water, you're missing an opportunity to save money on your electric bill to cool your house AND heat your pool at the same time. Mention me in a reply, if you want more details.

    i'd suggest replacing a few feet of your PVC pipes (probably on the high side just after your filter, the heated return line, and the main return) with clear piping. it's just nice to see what's going on at a glance, and if the filter material ever migrates downstream, you'll be able to see when the heater coils are clear. there are some nice flow meters you can get to get really good data over time (though can restrict flow if not oversized), and pressure sensors, and temp sensors, so that you can measure all that stuff every 5-10 minutes and hopefully catch stuff going wrong before it goes crisis. the sensors can be run off inexpensive electronics that can report over wifi - look up projects with the esp based SOCs. pie in the sky - you'd have temp sensors and powered flow adjustment valves so that you can increase flow when the upstairs tubing gets too hot and needs more flow to keep the temp up there down. i suppose you have a reflective tarp cover for times when it gets too hot. oh, and the pressure sensors are nice to keep tabs on when the filter needs maintenance.
    anyway, nice to see your progression through DIY heating options. i like that you've used the main circulating pump to do your work for you - i think the way our landscaping works, we'll have to have a separate pump for the solar heating system.

    Use black ABS pipe instead of white PVC.
    Starting at the lowest unit on the inlet side you could have saved money by using a 1.25x1x1 tee. Then reduce the 1 inch to 5/8 inch going to the 1st heater.
    At the 2nd heater use a 1x5/8x5/8 tee. Then run 5/8 inch line to tge 2nd and 3rd heaters.
    Repeat on the outlet side of the heaters.
    Further if you reduce flow to the heaters you will see a higher heater outlet temperature. Except with your setup you also increase the flow of water bypassing the heaters.
    This means you are combining the hot water with cold water. You will find that although the temperature of the heater outlet is higher the combined water should remain the same.
    Think of it this way.
    Decreased flow of heater with higher temperature.
    increased flow of cold water
    The average temp stays the same.

    You just forgot the time for heating. The water can not flow without stop to get heat.
    May use a timer or a thermostat. The thing is: water gets up and fill the hoses; stay imobile for some minutes; go back to the pool. After 10 minutes stoped under the sun the water can reach 100°C. But in a nonstoping cicle it gets less than 50°C

    If your goal is to get the most solar energy into the water, faster flow will get more energy into the water than slower flow. The temperature of the water from the roof will be lower, but you will get more water at that lower temperature, which will be more heat energy. Cold water absorbs heat energy better than warmer water. Put all the water to go up to the heater and more of the solar energy will get into the water, and your whole system will run better. You cannot run the water through the solar system too fast - the energy still goes into the water.

    A comment and a question:
    If the pipe is HOT it heats up the air around it, not the pool. Keep the pipes cool by running more water through.
    Have you measured the load on the pump motor? The pump has to work harder to push water through the extra pipe. I wouldn't be surprised if you're paying more for electricity for the pump than you would for gas for the heater.

    • @chrisbuildsitall
      @chrisbuildsitall  Před 11 měsíci

      Purpose of this system was to move more water faster which it did well but not good enough.
      Most pumps today show you the actual load/usage right on the screen. Almost no change on this system because it was such a short run.

    I think your polycarbonate covering causes you far more problems and about half of your cost than is will ever help you. Use larger black poly pipe or more circuits so that you can have your entire pump volume go through the heater without excessive pressure loss. The water should leave the heater only a few degrees above the pool temperature. At this temperature, there shouldn't be much loss to the surrounding air.

  • @FutureChaosTV

    You have the hot californian sun and a huge mound of stones/boulders that heat up in the sun...
    Why don't you use those hot stones/boulders and run the water from the pump over those in the style of a natural waterfall?

  • @falsedragon33
    @falsedragon33 Před 11 měsíci

    Those panels are quite inefficient. I have been using commercial solar panels for 15ish years. You want the water to flow as fast as possible without adding too much drag. The pool pump should be fed into a 2 inch header, where small poly pipes parrallel off that header 10 to 12 feet to another 2 inch header. I use a dozen 4ft x 12ft panels that have 30-50 pipes each, parralleling from one header to anotoher. The solar should not restrict the pool pump too much. If the panels are elevated above the pump, you will also need a vaccume release valve. Should really use one reguardless. It goes at the highest point of the system. Meaning, the solar pannels need to be oriented in a way where the feed ends highest corner is the highest part of the sytsem, and the vacuume valve get placed there. This will allow the pressure to equiilize when the water accelerates down the pipe. I use a valve at the bottom end to restrict the flow just to the point of satisfying the vaccume release valve. Without it, the pipes will heat, vaccuume, and collapse.

    Unfortunately, that's not PEX. That's irrigation tubing. Not nearly as resilient as PEX. I suspect this system may fail again due to the temperatures in your system. I hope I'm wrong, because you put a lot of effort into this, and I appreciate the video.

    You call that drip line “PEX” but it’s nowhere near as thick. I made the same mistake in using the drip line when I first built my system. It melted within a weeks. Use actual PEX TUBING and vent the enclosure. Water has to flow if the sun is out. I’ve had a system almost identical to yours heating my pool for the past 5 years. I live in the desert with temperatures over 110 at times and my heater is running strong.

    It better and cheaper and easier to just install Black plastic pool and cover it with clear plastic wrap. if you want it to last longer, install cheapest clear panels you can find, perspex, Acrylic, or glass. Keep a modest inclination on the mini pool on the roof, maximise surface area that is reliably facing the sun, avoid any shadows evaporation is a consideration too, and run the cool water into low point and let warm water rise to the output siphon. use the smallest pump possible. every watt you use pumping is a watt of heat lost...
    The pumping losses using poly tube is ridiculous. the heat loss on poly tube is ridiculous too..
    AND really obviously.. USE a pool blanket, you just cant beat it if you have good sun coverage on your pool.. simple cheap easy...

    @ryankenealy4837 Před rokem

    I’ve spent three straight summers doodling around with similar solar set ups, and I’ve come to this conclusion. Once the initial warm water inside the tubing is flushed out, you’re only circulating cold water. The only way this setup will be effective is if you have a timer for the pump that allows the pump to run for about 2 minutes, then shut down for a few minutes to allow the water inside the tubes to heat up again. Rinse and repeat. Also, the size of the pool is a big factor. The bigger the pool, the harder it is to heat.

    Don't know if you can hear yourself speaking, but you seem to be complaining a lot about how hot it gets. If it's so hot why do you need a pool heater?

I'm in New Jersey we get 3 months I definitely need a system to get my pool hot. Your weather seems to be fine

  • @EDesigns_FL
    @EDesigns_FL Před 10 měsíci

    I'm guessing that your third pool heater, like the prior versions, is not going to last very long. The primary issue is the wrong choice of materials. PVC is only rated for 140º F. Though polypropylene has a much higher rating (180º F), it's still not the best choice. CPVC and PEX are both rated for 200º F and would perform far better. Something above 212º F would be preferable, but the costs might be prohibitive.
    Heat management is the next major issue with your design(s). You want to get your pool a little warmer, not boil water. Getting the highest output temperature from your solar array is irrelevant to this goal. The most efficient method of accomplishing this goal is to heat a large volume of water slightly above your desired temperature, but you also want to keep the velocity of the water low. So you need more paths that are much shorter. Long coils are very inefficient.
    My suggestion would be use 2" CPVC for manifolds on the ends with 1/2" CPVC pipe collectors in between. The collectors should be attached to an aluminum plate, and all of it needs to be painted flat black. Water has to be keep in this system to prevent it from overheating or a solar shade needs to be employed.
    The negative pressure, created by the weight of the water in your system trying to drain back into your pool, combined with high temperatures, is what caused your prior designs to fail. The negative pressure problem can be resolved with a check valve on the input and a auto-closing valve on the output.

I do not see any temp ratings on the drip hose but it is for very low pressure non-heated water. If you are going to all that work, it might be worth your time to spend a little bit more on real hot water rated rated Pex. They use that stuff in heated floors.

    Plastic is doomed if you put it in an enclosed box...ideally stainless steel would be the ultimate solution but yeah, spendy.
    PEX home piping was my solution with 3/4 diameter and a high flow rate. It gained my enclosed pool with tight screen 7 degrees in the summer (NE Florida), which got me to high 80s which my wife was good with.
    I plumbed from the return and send side of the pump to get the pressure necessary, valve controlled. Make sure your pump timer kicks on at sunrise to avoid high heat gain at the start of the day. And off at sunset. If you arent pumping that tubing will melt down again...
    Sacrifice some temp for function...high flow to keep it cool...it will keep the system from melting down.
    Again from experience...and $$$ spent...
    The other option is some sort of temp controlled venting of the box to maintain a reasonable temp...never tried that though
