Covering a pool when it is not in use is the single most effective means of reducing pool heating costs. According to the Department of Energy, almost three-quarters of the heat lost by a pool is due to evaporation. By minimizing evaporation, pool covers significantly reduce heating needs and save energy, often by 50% to 70%. Minimizing evaporation also reduces the amount of make-up water by 30% to 50%. In addition, pool covers keep contaminants and debris out of the water, lowering the pool’s chemical consumption by 35% to 60% and reducing the filtration system’s energy consumption.
Automatic pool covers make it especially easy to be environmentally conscious.
