Why Pool Cover Required? 75% of a swimming  pool's  heat loss is due to evaporation. A solar  cover  or an automatic slatted pool cover minimizes heat loss from evaporation by acting as a barrier between swimming  pool  water and the air. Specifically, you can reduce your swimming  pool  heating costs by up to 80% by using a solar  cover. Swimming pool Energy loss Swimming pools lose energy in a variety of ways, but evaporation is by far the largest source of energy loss. Evaporating water requires tremendous amounts of energy. A)      Outdoor Pools Energy Loss The evaporation rate from an outdoor pool varies depending on the pool's temperature, air temperature and humidity, and the wind speed at the pool surface. The higher the pool temperature and wind speed and the lower the humidity, the greater the evaporation rate. In windy areas, you can add a windbreak trees, shrubs, or a fence to reduce evaporation. The windbreak needs to be high enough and close enough to the p
