Nice video filled with good tips & trix. I'm setting up a solar powered pool heater right now and my goal is 30°C / 86°F in the pool. I'm starting with 250 meters / 820 feet of 20 mm / ¾ inch PEM hose in a flat rooftop setup. A 20V rainwater barrel pump (2,000 liters - 528 gallons / hour) will be connected directly to a solar panel, so it's a completely automatic system controlled and powered by the sun. No sun = no pump = no heating. Since I'm located at 60° latitude in the northern hemisphere,I'll guess it'll be some problems and math to solve along the way, but it'll be fun. Keep up your good work
Nice set up. My question has nothing to do with the pool. I see in the video something that looks like a tower structure. Are you a Ham Radio operator?
Thank you! I'm not sure what you're referring to as I have nothing resembling a tower. I am not a Ham Radio operator, though I did flirt with the notion way back when I was in High School. Just never could get get past the Morse Code. 😂
I tried doing this same technique but the pool in the backyard, the back side of the house is a two-story to the roof and there was just too much head or too much head to push the water up, it couldn't make it up to the second story and around all of the tubing coils and then I tried a separate pump that was good for 45+ ft of head lift. bigish pump (or would I thought was big enough lol) I want to say it was a 1/2hp(gph4000) still wasn't enough to push it up around the coils and back down been trying to figure out a better way to do it as there's really not an easy place to stash a big board of coils in the backyard without it being in the way or looking ridiculous.. says the woman.. lol kind of bummed because it's a 20x40 in ground and in New England water is like freezing to swim in lol And obviously buying a big BTU heater is expensive plus the cost of fuels nowadays is crazy everything's crazy. Oh yeah the only places that I could mount it or mount a fixture or a box of the coils wrapped up wouldn't get a ton of sunlight throughout the day or until later in the day. We used to get a whole lot more sunlight in the backyard but over the years the tops of the trees have gotten very tall and we've lost 3 to 4 hours of sunlight because of it. Need to find someone to trim the tops of the hundred plus foot trees lol. If you have any ways to make it work on the roof being a two-story or any other things I might not have thought of after watching a bunch of these DIY videos feel free to toss some knowledge my way I'd appreciate it thanks for the video too. PS so sorry for the super long story probably won't even read it lol.
My neighbor's in the same situation you are, with his roof way too high. What he did was several long straight runs along the edge of his driveway. He has to be careful cutting the lawn and driving up and down his driveway, but it worked for him. I'm sure you'll figure something out! Good luck!
@@Dr.V. I have lots of great ideas and lots of ways it would work.. But.. they're ugly or look ridiculous or causing clutter blah blah blah lol says the Mrs.. like do you want warmer water or not.. haha oh man this is going to be the second year maybe the third year trying to figure something out I have other ways to mount it to like the side of the wall or the chain link fence but she won't let me either build a case for it or put some kind of back blacking behind it to help soak up the heat so I feel like it's essentially working at 50% you know what's the point why bother?.. lol But I guess I'll figure something out eventually definitely not fun going up on that roof though What a nightmare it was getting all that tubing up there and then having to lug it all back down It is very very steep the pitch of the roof It was so sketchy 😂🤣. But thanks for the reply. fingers crossed!
Hi Is there a certain rule for calculating the length of the hose and the amount of pool water, meaning every thousand liters, how many meters of the hose is needed?
I don't know of any rule, per se. I figured more is better and easy is good, so I used 100 foot long rolls as that's the way Lowes sells them. When stretched out, you can see they offer good coverage of my roof.
@@hambone1113 Length and area are two different things. Such a calculation does not make sense to me. As it turns out, my pool is 648 square feet and that's almost exactly the length in feet of my black pipe and hose on the roof. So even though the calculation doesn't mean anything to me, I nailed it. 😂

Thank you! Good luck with your project and keep us posted on your progress!

What a great idea! Thanks for the explications.
You're welcome Marc!
I missed the significance of the 3.5 coils minimum that you calculated. What does that mean and how is it manifested in your design?
It prevents back-pressure to the pump, which it is not designed to deal with.

Even at 50% efficiency the heat is free@@luckylarz4269. 😉
@@Dr.V. Indeed you are correct sir 😎

Your hose length should equal half of your pools surface area
