Solar Cover Heat Retention Calculator
Calculate how much heat and money a solar cover saves by reducing evaporation and retaining thermal energy in your swimming pool.
Stop the Evaporation
Over **70% of a pool's heat loss** occurs due to evaporation. When water turns into vapor, it carries away a massive amount of thermal energy. A solar cover provides a physical barrier that stops nearly all evaporation, keeping that heat in the pool where it belongs.
Pro Tip: Transparent or "clear" solar covers are best for heating during the day, while opaque or blue covers are slightly better at retaining heat at night.
Frequently Asked Questions
Should I use a solar cover during the day?
Yes, it helps heat the water using the sun's energy (the "greenhouse effect"). However, if your pool is already over 90ะยฐF, you might want to leave it off to let it cool down slightly via evaporation.
Does a solar cover affect chlorine?
It actually helps! By blocking UV rays and stopping evaporation, it can reduce chlorine consumption by up to 30%. Just remember to take it off for a few hours after a heavy shock treatment.
