    Keep Water and Heat Loss at Bay with Pool Covers

    Hot days are a pain, but they make for a great time to take a dip. A pool can beat the heat as long as the heat doesn't beat the pool first.

    Where there's water and heat, there's bound to be a drop in water levels; pools, reservoirs, you name it. Water loss from a pool depends on the pool size, humidity, temperature, and wind velocity. A 500 square-meter pool in 77-degree weather and 50 percent humidity may lose 49 ml of water a second. A minute later, it may lose as much as three liters.

    When heat comes to your backyard pool, make sure you're prepared to fight the heat's fight. Pool covers are designed to reduce, if not eliminate, the amount of water lost to evaporation. Pool covers in the market can either be silicon or isopropyl alcohol-based that can reduce the evaporation rate by up to 50 percent.

    Pool covers also work in another way: heat retention. Summers are usually mild in the northern U.S., so a warm dip is always good. Statistics show that 70 percent of heat from a pool is lost from evaporation, both for indoor and outdoor pools. This results in increased cost of heating a pool, namely installing a heating system that can cost thousands.
