Solar Pool Covers

Solar Pool Covers

Thermo-tex technology maximizes the heating blanket’s ability to absorb thermal energy and maintain it. Superior light diffusion properties enhance the sun’s solar rays. The result is a warmer pool, energy conservation and lower operating costs. By minimizing convective heat loss, the blanket is also effective in keeping indoor pools warmer.

Pool covers are the most cost-effective measure to reduce heat loss, water evaporation, and chemical use. Not having a solar pool cover is akin to heating a home with the doors and windows open.
All heating systems should be used in conjunction with a solar pool cover to ensure a cleaner, warmer, and more enjoyable pool.

In addition to significant energy savings, solar pool covers do the following:

– conserve water by reducing the amount of make-up water needed by 30%–50%
– reduce the pool’s chemical consumption by 35%–60%
– reduce cleaning time by keeping dirt and other debris out of the pool

Why do I need a solar pool cover?

Covering a pool in-between periods of use is the single most effective means of reducing pool heating costs. As much as 70% of heat loss from a swimming pool is evaporative. A pool cover acts as a vapor barrier for both indoor and outdoor pools, dramatically cutting heat losses from evaporation, resulting in significant energy savings.

Why does evaporation cause so much heat loss?

Evaporation requires a tremendous amount of energy. While it only takes 1 Btu (British thermal unit) to raise 1 pound of water 1 degree, each pound of 80ºF water that evaporates sucks 1,048 Btu of heat out of the pool.

The evaporation rate is dependent on the pool’s initial temperature, the surrounding air temperature and humidity, and the wind speed at the pool surface. The higher the pool temperature and wind speed and the lower the humidity, the greater the evaporation rate. Though a windbreak— such as trees, shrubs, or a fence—can reduce evaporation, it may shade the pool from the sun, which is a strong natural heat source for the pool.

Do indoor pools lose heat to evaporation?

Though indoor pools aren’t subjected to the elements, they still lose the same percentage of energy from evaporation as an outdoor pool. The humidity in an inside pool area is evidence of high amounts of evaporation. An indoor pool requires ventilation and air conditioning systems to cut through the humidity, which increases energy costs.

What are the climate considerations for pool covers?

To determine the effectiveness of a pool cover, consider whether the evaporation and other losses prevented by the cover exceed the solar gain reduction caused by the cover.

Dry or windy conditions increase the evaporation rate off the pool’s surface. A pool in this environment benefits from a transparent or bubble cover to maximize light absorption. As warmth and humidity increase, the evaporation rate decreases.

What are the different types of pool covers?

Pool covers are designed using UV-stabilized polyethylene, polypropylene, or vinyl to resist deterioration. A cover lasts several years.

Solar covers are reminiscent of bubble packing material, but using a thicker grade of plastic with UV inhibitors.

Vinyl covers consist of a heavier material and have a longer life expectancy than bubble covers. Insulated vinyl covers are also available with a thin layer of flexible insulation sandwiched between two layers of vinyl.

Pool covers have a greater net gain when combined with use of a solar energy system. Ask our friendly customer service representatives about pool covers and solar pool heating systems by calling 1-866-786-7763
