Help with pool heating design

Forced to post too! What a system

I am interested in doing something like this and want to see pictures/attachments(?), and I have to post, so I am!

My message is apparently too short, so I am posting more here...

Hello Attachments and welcome to Solar Panel Talk!

[attachments11]

Want to see pictures...

are there any downsides to doing all of this i like the idea of the manifold but will my pool suffer as far as water quality from bypassing the 3 jets that stream into the pool or would all be fine?


heres a quick diagram i threw together would it be something like this?

Hi...,

Solar pool must have the high resistance polymer central body, with mixer for hot and cold water to set the perfect temperature. It must have pool filter for passing the water at least once in the day. These are some of the required conditions for designing the pools.

I think on a slanted platform, it would be better to have the water entering the heating pipe on the higher side and the outflow on the lower side to help the pump. Am I correct?

No pump in the low side and out the top

intake & outlet locations

Great ideas. Should help with my build.

That may be , but being such a stickler to take an off hand comment and try to drive home scientific requirements is foolish. I agree on the 100ft but if you look at the original post he had a very nice and very well laid out set of 5 coils 200ft each. Thais why I stated to make the manifolds with 5 200ft coils.

[Naptown]

Russ wasn't questioning your method (although I would limit the individual coils to 100' and have more of them)
This is the proper way to do it
The math and performance claims was being questioned

[tonytheroofer]

Go ahead and run 1000ft of tubing in one long string and claim it is the best way to transfer heat back to the pool. If any claim is wild it is that senseless claim. Manifolds make the system perform leagues better and if your mind needs a math equation to understand it that's an issue for you to solve not me. I stand by 1 1/2 pipe t reducers to tubing size feeding each 200ft coil feeding it back into a return manifold the same as the inlet manifold powered off the filter pump.

[russ]

Your project so you do it - I am just pointing out you are making a wild assed guess and posting it as fact - some believe this type of claim.

Will be a very small increase in the real world.

[tonytheroofer]

Maybe not 10 but the manifold system would be so much better it would be like apples and oranges , and because I am not interested in exact math feel free to do it

[russ]

Doing it this way you will get max flow with least effort on pump and gain 10 times more heat to pool then using a single coil of 1000ft. If I had used 1000 feet i would have made 5 200ft coils and piped it into the manifolds.

Think your math is a bit questionable - less length is less pressure drop but gaining 10 times the heat - no.

Manifolds are a MUST

Hi, I have made solar my heater with 500ft of irrigation tubing , I used 1 1/2 PVC and T connectors for 5 upper and lower headers. I used 3/4 to 1/2 reducers off the T and coiled up each 100 roll of tubing. I set it up on my flat roof with a manifold inlet on the lower and the out let on the upper , make sure intake and out let are opposite ends of manifolds and the return line is higher then the out let manifold to ensure all coils are fed proper water. Doing it this way you will get max flow with least effort on pump and gain 10 times more heat to pool then using a single coil of 1000ft. If I had used 1000 feet i would have made 5 200ft coils and piped it into the manifolds.

As far as return water pr even feed you will use the same hoses you already use on the pool so size PCV and adapters by that standard.

Indeed, I believe the connectors are a differant grade/formulation of EPDM. I've seen the same and they do hold up pretty well. There is also much less surface exposed to water in the connector.
The collectors I had the problem with were "solar rolls" and the EPDM was more like the membrain they use for roofing. It's my understanding that the company had to pull all of this product and do a redesign.
