Short video of how I hooked up the GAME solar water heaters to a solar powered water pump. With this flow rate the water coming out is 4 to 5 degrees warmer than the water going in.

It was early June and the outside temps were probably 85 and the pool does seem to be 2 or 3 degrees warmer than this time last year (they have been hooked up for over a month now). If you decrease the flow rate the water will get actually very warm but as far as thermal transfer to the pool you probably wouldn’t gain anything.

These things get bad reviews on Amazon and I understand why. If you used a hi flow high pressure pump as suggested in the instructions I doubt there would be any heat transfer at all. But with this little solar water pump the pressure and flow are pretty low and I think its allowing them to work as advertized.

If you were to use a similar setup at a cabin to heat up maybe 40 gallons (continuous circulation) for hot water I have no doubt it would work great.

    Nice setup. Do you have a link for the pump and the Sun panel?

    So what was your final conclusion on how your setup worked? Was the 1/2 piping enough? I would like to convert my 3 solar heaters to a solar pump so i dont have to worry about turning the the pump off in colder shady days

    Hi could I ask what solar pump you used…as it seems to be 38mm connections

  4. Mat Burchett Posted on July 7, 2020 at 8:58 pm

    What about when your in it do you turn pump off?

    DO NOT BUY ONE OF THESE! The parts are obsolete within 3 years of product creation. Such a scam! Need to throw away $150 item because cannot find the $30 part. So bogus!

    My works too. Used Avasva handbooks and build it with no problems.

    Any chance you could share a link to the solar panel you used? thanks

    what kind of solar pump was it, and would you recommend buying one.

    I have to run the bypass because the water gets too warm. I'm using 2

    Update, this weekend we had temps in the mid to high 90s and the water exiting the heater was over 10 degrees warmer. Its actually working very well in my opinion.
