Black plastic coiled collector questions

[J.P.M.]

J.P.M. do you have any books you recommend?

I think starting with what's available from outfits that mfg. and sell solar pool heating equip. might be a good toe dip. After that, a for dummies type book on the basics that includes solar thermal would be the next step. See the net.

While not trying to come off as an f-bombing know it all, for me only - It ain't exhausting. But know this: IMO, you will be better off spending 20 bucks on a solar energy book that covers pool heating. An hour or two into it and you may see and begin to understand why some of what you say about exhaustion may hold a kernel of truth for some. You'll also get most of your questions answered. Bonus: The remaining questions you will have will probably get better answers and in the end, your pool heating attempts will be better, cheaper and happen faster.

Thank you Russ and J.P.M. for all of the information provided. I know you guys get noobs like me all of the time and answering the same questions over and over must be exhausting. The information I have gleaned over the past few days has me on what I feel will be the right track.

Ohn gee! Provide half assed information then whine when it isn't accepted.

Do as you want - just don'y cry when it goes wrong. Any flex pipe like that will have far more build up problems - really a bad idea. TrynIndego - this kind of stuff they love

Not whining, just trying to have an intelligent discussion. Build up as in debris inside the pipe? The inside of the pipe is smooth like a regular flex pipe, just the outside that is corrugated. And who is this Indego you speak of?

Although this site does not list a pressure rating, other sites list the same product at w.p 125 PSI b.p 350 PSI.

Labeling something garbage when you don't have all of the information is a little closed minded.

P.S.

This product has a tighter minimum bend radius and higher working pressure then flexible PVC and flexible HDPE pipe; two pipes which I have seen recommended in other places.

Good stuff - no pressure rating - is a drain pipe most likely - zero pressure nominal

This is junk

Thats funny, but this I believe meets all of my previously stated qualities? So would it increase the amount of heat transferred by increasing the surface area of the outside of the pipe without increasing the inner diameter? Everything I know about heat transfer, although not specifically for creating pool heaters, says that it would collect more heat from the sun and transfer that heat to the colder water inside the pipe. Would this not be so?

Russ if corrugated plastic pipe wasn't weaker, is UV stable and is set up with the appropriate control system would it be useful?

Weaker as well - why use garbage when you can use something better?

you stated a tight coil to create the most surface area possible is desired.

And a larger area for heat loss like a radiator. Don't waste your money.

As stated before I am not recommending these to the club. Although I do need to ask why you would be opposed to corrugated pipe? With more surface area to transfer heat, while the coil temp is higher then the temp of the pool water you would have a positive effect on the amount of energy transferred. If set up properly to shut the pump or close a diverter valve when the coil is not heated by the sun there should be no/minimal heat loss from the pool because of the larger surface area.

It seems odd to me you would be opposed to corrugated pipe when in a previous post you stated a tight coil to create the most surface area possible is desired.

[J.P.M.]

Ya, they are undersized for a bucket of water! The only saving grace I see for them is the corregated pipe increasing surface area of transfer and the enclosed system.

Those coils are a total ripoff - you need black plastic pipe
