Why electric pool covers?
Pools lose energy in a variety of ways, but evaporation is by far the largest source of energy loss for swimming pools. When compared to evaporation, all other losses are small. Since evaporation is the major source of heat loss for all swimming pools, to minimize evaporation one must cover the pool. Covering the water with a pool cover when it is not in use is the single most effective means of reducing heating costs. Savings of 50-70% are possible. Increasingly popular, but relatively expensive, are automatic pool covers, which cover and uncover your pool at the touch of a button or even by remote control.
