    Another crazy solar pool heater diy idea....

    Are you guys familiar with 'pillow tanks' used for water storage? Can be used for agriculture or potable water needsome etc... Any ways the sizes vary from small to huge...

    I have an idea to route pool water into a black storage tank, let the sun heat the bag, then route it back into the pool.... say I have a 10'x14' 2400 gallon bag. I could use it seasonally then store it in the winter.

    Thoughts? If you Google pillow tank you'll know what I'm talking about. Made from high strength pvc material. I don't like the idea of buying new solar panels when they are only useful about a month or so on each end of the swim season here in AZ And have them exposed to the elements the rest of the year...

    Are you suggesting continually moving water through the bag?
    It is much more efficient to heat a lot of water a couple degrees that a little water a lot of degrees.
    And solar heating is about sqft of exposure to the sun.

    How big is your pool?

    My pool is 15000 gallons. Yes I'm thinking I'd continually move water through the tank and place it on an unused patio next to the pool in the sun. I'm in Scottsdale AZ.

    So why not just get some inexpensive solar mats to sit in the same place that you can roll up and put away?

    Solar mats? I've seen some on Amazon and Ebay but was skeptical of the quality. Anyone with reviews? They seem too small to do any good...

    Solar mat/panel whatever you want to call them. You need many of them to have surface area for the sun to hit.

    If surface area is what you need, then this is the solution. Holding 2500 gallons of water vs a 4x4 mat holding 1 gallon.

    But you want high flow rate and small temperature rises for better efficiency.
