Without a cover
Like a house without a roof, a pool without a cover is impossible to heat cost effectively. Without a cover pool owners must continually replace heat and chemicals lost to simple water evaporation. And because the water is is exposed to the elements, pool filtration pumps use more electricity than is necessary. That wastes valuable resources needlessly and can cost you a lot of money.
With a Cover
There is no better way to to conserve important natural resources than a pool insulation cover whether it is a solar or automatic Venetian, Its like a roof for your pool that helps keep out the undesirable things like dirt, insects and leaves whilst keeping in the good things like heat, pool chemicals and water. Its the perfect "green" solution for pool owners who care about the environment and want to save money on operating costs.
Water evaporation is the single largest cause of heat loss from a swimming pool. For every gallon of water lost, over 10,000 BTU of heat from your pool is wasted Using your insulation cover when the pool is not in use will reduce water evaporation and heat loss up to 70%
Proper pool chemical levels are essential to maintain healthy water, but they need to be replaced and balanced frequently in pools without a cover. A pool cover helps pool chemicals from dissipating so rapidly which helps keep them in balance longer. That means less expense and effort in keeping the water ready for swimming.
Pool filtration is vitally important for a healthy pool. An open pool needs to be filtered at least every 8 - 10 hours a day because of dirt, leaves and insects as they accumulate in just a few hours. Because most of the dirt and debris that normally falls into a pool is sealed out, filtration cycles can be limited to just a few hours a day saving you up to 50% in electricity.
In many parts of the country water conservation is a major issue for local governments, water companies, and environmentalists. Concerned pool owners should do all they can to conserve this important resource. Like a lid on a jar an insulation cover prevents most water evaporation, That makes it possible for you to do your part in conserving water in your community,
