According to the U.S. Department of Energy, backyard swimming pools lose energy in a number of ways, but evaporation is the most significant source of energy loss. In fact, 70% of energy loss in swimming pools can be attributed to evaporation.
Four factors determine your pools’ evaporation rate. Temperature, on air temperature and humidity, and on the wind speed at the pool’s surface. The higher the temperature of the pool, the higher the wind speed, and the lower the humidity, the greater the rate of evaporation. If you live in a windy area, you should install a wind barrier like strategically planted trees, or a tall fence, evaporation. The wind break should be high enough and near enough to the pool so that it doesn’t create turbulence over the pool, which will increase evaporation. You also don’t want the windbreak to block the sun from the pool; the sun helps to heat the pool and keeps it warm over time.
Creating an environmentally friendly swimming pool is achievable, important and simple to do. First, use Solar Covers, also known as solar blankets, to cover your pool. Solar Pool Covers or Blankets resemble enormous sheets of bubble wrap. The bubbles trap heat from the sun and convey the heat to the pool, keeping the water temperature warm and comfortable. The solar cover also helps to trap the water’s heat and prevents heat loss in the cooler air at night or on cooler days. Solar covers float freely on top of a pool without the need for tie-downs or anchors to secure them. Solar covers are usually folded and stored or rolled up in a large roll and wheeled out of the way. Solar Blankets are perfect for use in sunny climates because the more heat they can trap, the longer they can extend the swim season. Solar pool covers can increase water temperatures by as much as 10-15 degrees.
Besides offering energy savings, pool covers also do the following:
- Save water by decreasing the amount of make-up water needed by 30%–50%;
- Reduce the pool’s consumption of chemicals by 35%–60%;
- Reduce cleaning time by preventing dirt and other debris from entering the pool.
