How do solar pool covers work?

Solar pool covers or blankets, are specially designed sheets that are placed over your pool in order to contain warmth. Solar pool covers work by creating a barrier between the water and the air. This barrier is made up of numerous bubbles that provide a magnifying type effect, which enhance the heating power of the sun’s rays. Additionally, as the blanket covers the pool water, evaporation is greatly reduced, ensuring that the warm water stays in your pool.

Solar energy is the most efficient way to heat your pool. It provides you with a cost effective way to maintain comfortable swimming temperatures all year round. When combining your solar pool heater with a solar pool blanket or cover, you can reduce the workload of your solar pool heater by containing the heat within the water. Resulting in you requiring the solar pool heating less frequently.

Other benefits of solar pool covers include, preventing the loss of cleaning chemicals via evaporation and shielding your water, stopping bugs, leaves and debris from falling in.

So how do you use a solar pool cover?

To prepare your Solar Pool Blanket for installation, lay it out with the bubble side facing downwards over your pool. The bubbles provide separation from the pool water and provide a magnifying effect that will increase the heat gained from the sunlight over your pool.

Depending on the size and shape of your pool, you can trim the pool cover to better fit over your pool. It is most effective if your pool cover fits exactly over the water of your pool and acts like a skin on the surface. Ideally you do not want any extra segments of the cover to extend over the edge of your pool, as this will significantly reduce the effectiveness of your cover by allowing for greater evaporation to occur.

You will want to use your Solar Pool Blanket to cover your pool whenever it is not in use. Of course, daytime is the most important time for heating your pool as it relies on sunlight, and leaving your pool covered overnight will prevent the loss of heat through evaporation. This means that you may be removing and replacing your cover routinely during your swimming season.

How do I remove and store my solar pool cover?
If you swim in your pool regularly, removing the Solar Pool Blanket can be tedious and reduce the enjoyment you get from your swim. In order to more easily remove your pool blanket, you have some options available:

  • You can trim the blanket into smaller pieces. These smaller sections can be removed individually with less difficulty.
  • You can pull the end of the solar Pool Blanket from the pool and fold sections at the end of the pool.
  • You can install a Solar Blanket Reel so your blanket can be rolled up neatly.

Solar Blanket Reels are a practical way for you and your family to remove, store and replace your blanket on your pool each time you want to swim. The reel can be permanently installed at the side of the pool or often reels can be wheeled into place prior to use.

Whether you decide to buy a Pool Cover Reel or not, it is important that you remove the cover completely before anyone swims in the pool. If anyone is to swim whilst the pool cover is on, there is a high danger of that person being trapped under the blanket.

Solar Pool Blankets are an effective and convenient addition to any solar pool heating solution. By trapping the heat in the pool you lose very little water via evaporation, and ensure that the heating system is working to its full potential.
