Energy Savings - Alta Enterprises



Energy saving Pool Covers

A hallmark of Alta swimming pool covers is energy efficiency. Our customers routinely experience a 35% - 40% percent reduction in their natatorium heating bill. This typically equates to $12,000-$20,000 in annual cost savings, depending on the size of the pool. To receive a cost savings estimate for your facility, please click here.

Swimming pools lose energy in a variety of ways, but evaporation is by far the largest source of energy loss. Evaporating water requires tremendous amounts of energy. It only takes 1 Btu (British thermal unit) to raise 1 pound of water 1 degree, but each pound of 80ºF water that evaporates takes a whopping 1,048 Btu of heat out of the pool.

 

Indoor Pool Covers

Indoor pools aren't subjected to the environment, but they still can lose a lot of energy from evaporation. They even require room ventilation to control indoor humidity caused by the large amount of evaporation. The ventilated air also must be conditioned, which adds to the energy costs. Pool covers on indoor pools not only can reduce evaporation but also the need to ventilate indoor air and replace it with unconditioned outdoor air. You can also shut off exhaust fans when an indoor pool is covered, which saves even more energy.

Outdoor Pool Covers

Outdoor pools gain heat from the sun, absorbing 75%–85% of the solar energy striking the pool surface. This is an important contribution to the pool's heating needs. A pool cover will decrease the solar gain contribution to some extent, depending on what type you use. A transparent bubble cover may reduce pool solar energy absorption by 5%–15%. A completely opaque cover will reduce it by 20%–40%. You need to consider this when selecting a pool cover.

 

Other Pool Cover Benefits

Besides offering energy savings, pool covers also 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.
