Hello to All,
Summer in the south is here !! I really liked when the water was 70-72 and it cooled you off 2 months ago.
Have relatives in for wedding this weekend, and wanted to get all of your opinions on what ways cool the water the best and what is the primary reason the water is cooled? I will state that a chiller is best, we do not have one and adding one at this point is not feasible.
Any circulation at night seems to be the winning answer, but what and how it cools is my question? When I turned on the two scuppers, the water that came out for about 10- seconds was really cool. This is bc the pipes are buried 2+ feet deep and not exposed to the sun and the water cooled in there by not being circulated and mixed w warmer pool water. I would conclude that running the scupper pump at night would cool the water X [minimal] degrees bc it's moving water from the pool and circulating it w the cooler air than pool water temperature. Also, since the ground cools at night, thus where the PVC pipes are located, doesn't running water thru a "cool zone" or stretch of PVC pipes in a cooler area cool the water as it runs thru it? Our PVC pipes from equipment pad to pool makes about a 100-110ft run. I am assuming the long run of buried PVC pipes are similar to the principle of a tankless water heater.
So, what really is the prime reason that cools the water at night? I know it has to be circulated, but is it just the circulation process of moving the water from deep to top or cooling the water going thru the cooler pipes? Would assume it is a combination of both, but I am seeking to ascertain what is the main or prime reason?
