Solar Pool Heating - Optimal Timing for Highest Temperature

Surfer Dude on 04/02/2021 - 14:44

Hello Ozbargain,

Can you please comment and let me know what time of the day you are running your solar heating for your pools (include the east/west positioning of your solar heating)?

I am trying to get the pool to the hottest possible temperature (over +30c degs) and am curious to see what others have done. I am currently trialing a 30 min on, 30 min off method from 9am to 12:30pm as my tubular rooftop heating faces East (theory is that it gives the tubular pipes 30mins to get heated up from the sun then 30mins of pumping that heat into the pool).

    My roof top pool solar blanket has a sensor that turns the solar heater pump on and off to maintain a prescribed temperature (in my case 28)

    I just let it do its thing.

      24C setting for us, we leave the blanket off overnight if water reaches 28 and expecting following few days of 30+.
      I remember reading in the booklets that 28 or 29 and above is detrimental to pumps and or seals?
      we currently have it set to winter mode (daily 2 minute flushing cycle) as the blanket is keeping it warm enough

    i have metal deck roof that the tubular pipes sit on.

    on a really hot day the roof gets to about 60 degrees. and the water that comes out of the jets is hot enough to scold you..

      how did the water coming out of the jets scold you? how did you respond?

    Since you are facing east I'd just leave it on all the morning - turning motors on and off repeatedly is what ruins them and whilst it's off some excess heat will go into the atmosphere rather than the pool water. But you'd get a lot better result with a west-facing array; I run my solar from about 10am to 6pm.

      Thanks mate, cant run it west facing as the PV solar panels are on the western side of the house unfortunately..

    The required time it takes your pool to heat up depends on several factors like- heat pump size, air temperature, pool size, and material used to heat the pool. However, you should note that each pool is different, and heating times vary. Heat your pool during the day for more efficiency.
