ENERGY SAVING POOL COVERS & REEL SYSTEMS
Swimming pools lose energy in a variety of ways, but evaporation is by far the largest source of energy loss. Evaporating water depletes tremendous amounts of energy. It only takes one Btu (British thermal unit) to raise one pound of water 1° F, but each pound of 80° F water that evaporates takes a whopping 1,048 Btu of heat out of the pool. 70% of energy lost from indoor pools is the result of evaporation. Pools require room ventilation to control indoor humidity caused by the large amount of evaporation, which accounts for another 27% of lost energy.
