The colder the hose is, the more ambient heat it absorbes. (a thin walled hose also absorbes more heat than a thick walled, due to shorter travel distance from the water to the ambient heat). This is, as mentiond by @Flapswgm, the principle of heat exchange. If the flow is high, the hose (and the outlet water) will be colder than with low flow, but it will transfer more total BTU's to the pool. As @MrPensiveThinker said: Try to isolate the spiral from wind by building an air tight box around it, with a glass (or polycarbonate) top. This will make your setup work alot better.

I am running 4x 500ft coils running in parallel and my output water temperature is 135. Mine is and inground 20,000 gallon pool and it heats it beautifully. We haven’t used the pool heater this year
@@carloscasillas7867 very nice. I usually have to run mines because the temp change at night. I need to find an option to retain the heat overnight. I’ve seen solar covers but seems like a pain to put on and take out each time. Otherwise my solar heater works great and I have 3 currently. 😀
Should do a followup video seeing the difference in overall pool temperature. The pitcher was a good test case, but it'd be cool to see the entire pool temp difference as well. Thanks for sharing!
Lovely video! I think the flow isn’t really that important since the heat is going to be put in the pool anyways. If you could build a glass box to go over your solar panel that would probably increase the heat by a few degrees since it wouldn’t allow it to escape. I would also have all the hoses with the heated water submerged into the pool as the water contacting air while its falling cools it off.
Flow does matter though. Its the difference between the water in the coil heating up 4 more degrees or it being pushed through too quickly and only soaking up a little bit of heat. Cars go through this thermal dynamic process when trying to get cold air to the intake plenum. The restrictive piping allows for the air move slower through the whole system which results in what we call heat soak (Unlike a car you want this for the pool), so in a car we open the pipes to a bigger diameter to move more quickly to the intake without heat soaking so much. So the idea with the pool is finding the perfect flow to where you get maximum heat soak in a good amount time to heat the pool. If you dont do this it wont matter if you get the coil water up to 200 degrees, if it takes 60 hours to heat it up. Too much time will allow the heat being pushed to dissipate, especially with larger pools. Gotta find the perfect Time x heat soak
@@don_wynn no worries. Just thought I'd make it known. I'm also battling with a too cold pool. That's how I stumbled across your video. Great job by the way
Its not about temp as much as it is about volume. Remember that your pool's surface area will remove higher temps unless the volume or hot water is so great the pool can't get rid of the heat. If you transfered 200 degree water into your pool but it came in at a rate of 3 gph, your pool would not get any hotter. You would lose all that heat from lack of volume. Remember heat exchange is either EXOTHERMIC or ENDOTHERMIC. Very important info to measure.
@@MrJjohnson28021 hi no, you’d have to find a way to cover it. Our water temp drops overnight and I have found a good way to cover the pool overnight without having to deal with a large cover I don’t cover it

@@joarandrehansen thank you so much. That was a superb explanation. I will work on improving the model.
@@don_wynnat least learn how to appreciate people's hardwork. You can politely suggest your thought. Stop being rude please. This is 21st century.

Nice. Loved the real time ingenuity/creativity on display during the build section! Respect Sir!

cuanto tiempo tarda en calentarse toda la piscina y cual es la temperatura inicial y final? gracias

For sure I will try to get a video up but that was last year I haven’t even open my pool this year because of crazy California weather 😂
What adapter did you use for the return to tubing?
Can you run the center pipe (inlet) under the palette? No shadow/shading on the coil.
🤯 I didn’t think about that, that’s a great suggestion 😀
Nice job and great video!!
@@drewpearson7911 thank you so much
Where did you source the plastic pallet from?

@@hardstyle4life0 thanks I appreciate it 😀
How did you get the water into the black hose and where is the return hose hooked up to?
Water came from the return of the pool pump…

The whole video is complete nonsense, one of the many videos to many time regurgitated BS.
Enjoyed the video. Thanks for sharing
Thanks. And thanks for watching
Does the water stay warm at night once the water is warm
@@MrJjohnson28021 hi no, you’d have to find a way to cover it. Our water temp drops overnight and I have found a good way to cover the pool overnight without having to deal with a large cover I don’t cover it
Don't forget about heatless overnight
Is there anyway to contact you directly
In what world is 22 degrees to cold? Dont tell me: “the California world”….
