How to Choose Solar Covers For Pools

by Pool Builders on 05-11-2010 in Articles

The greatest loss of heat and water from your swimming pool is due to evaporation. Even when the sun is shining down, the water reflects much of it's warmth and evaporation causes significant cooling of the water and water loss.

A solar pool cover can help capture the heat of the sun and stop much of the evaporation saving energy, water and money.

A solar pool cover may also be called a solar blanket. Solar covers are not safety covers and lay on top of the water in your pool. They do not attach to the pool. Solar covers must be removed before using the pool. They are relatively light weight and reels are available to make it simple for only one adult to remove the cover.

Solar pool covers look like large sheets of bubble wrap. They are usually transparent, but are available in colors. The air in the covers absorbs warmth from the sun and transfers it to the water.

The plastic of the cover prevents water from evaporating. Users of solar covers have reported savings of between 40% and 70% on the cost of heating their pools.

Most solar pool covers are sold in standard rectangular sizes. There are other solutions for pools that are irregularly shaped. There are round solar pads with magnetic edges that can be tossed into the pool and will act as a solar cover.

While these discs are not quite as effective as a standard solar blanket, they still can save a significant amount of energy. In addition to the round pads, there are liquid filled solar "fish".

These fish shaped solar collectors are not effective at preventing evaporation, but they will collect and disburse solar heat and can be left in the pool while it is in use.
