DescriptionThe Thermo-Tex™ Solar Spa Blanket is manufactured with THERMO-TEX™ technology, which is an additive that maximizes the blankets ability to absorb thermal energy and maintain it, providing superior light diffusion properties that enhance the sun’s solar rays. The results are a warmer spa, cutting heating costs up to 70%, energy conservation, reducing water evaporation by up to 95% and lowering your use of chemicals. Made from top quality, low-density polyethylene Dow prime resins with super strong seams and wider panels this blanket will lay flatter and is lightweight and easy to handle. The THERMO-TEX™ Solar Spa Blanket is also effective in keeping indoor pools warmer due to the reduced convective heat loss. Blankets are square and can be cut to fit round spas. Back to Top
More InfoWhy 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 and spas, 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 80°F 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. Back to Top
