We live in Tulsa, OK and our summer days have been heating up to 100+ with high humidity and high heat indexes. Our inground saltwater pool is 25,000 gallon with a medium lagoon colored bottom with in-floor cleaners. Our pool is exposed to the sun most of the day.
Our pool water was heating up to 95 degrees and it was awful - you would get in and you would just be "wet" - it was not refreshing and not enjoyable.
We started doing research on a pool chiller and found Glacier Pool Chillers. There are 2 models and we went with the larger residential unit to maximize efficiency.
After installation - we had to tweak the pressure and intake valves to accomodate our in-floor cleaning system - but within 4 days (chiller was on entire time) our pool went from 95 degrees to 83 degrees. It is almost too cold!
It is awesome! We highly recommend this product for anyone that is suffering from hot bathwater in their pool. The units are a bit pricey - but isn't having a pool all about quality of life?
