POOL  HEAT & EVAPORATION

Swimming pools lose energy in diffferent ways, but evaporation is easily the most significant cause. Evaporating water requires a lot of energy. It only takes 1 BTU to raise 1 pound of water 1 degree, but each pound of water that evaporates takes 1,048 BTU's of heat out of the pool.

Blanketing your pool when it's not in use is the most effective way to reduce pool heating costs. Savings of 50-70% are possible; but taking a cover on and off all the time is a hassle. The tropical Fish Liquid Solar Blanket is 100% easier to use.

A 7 mph wind at the surface of the pool can increase energy consumption by 300%. Adding wind breaks such as fencing, trees, shrubs, can lower heat loss if they are not overhanging and creating shade, but are high enough to reduce wind.
