The most common type of sun cover is a sun blanket. Made with small thermal bubbles, they are excellent for retaining heat and water in swimming pools. A solar disc can provide the same benefits as a solar blanket with much less volume. The 500 micron Sol+ Guard cover is the recommended cover for all outdoor pools and the Geobubble Raeguard or Raeguard Weave cover is the recommended cover for maximum heat retention in an indoor pool.
Clear covers are ideal when the sun shines on your garden for long periods of time. If your pool gets less than 6 hours of direct sunlight a day, you can try a different color cover (such as blue), which will absorb more heat in less time. A sun cover is essential and should be on the surface of the pool at all times when you are not swimming. If a perimeter fence isn't right for your space, it may be better to have a solid security cover for the pool. It is now widely accepted that installing a heat retention cover is the most effective means of reducing pool energy consumption.
If your top priority is a cover that provides maximum solar gain, then a more transparent cover may be right for you. Covering the pool also prevents dirt and debris from entering the pool, maintaining the swimming environment and reducing the demand for chemicals. The surface of the roof can then transfer heat to the water, conducting it or transmitting it, depending on the type of solar cover. Solar covers can also save money by helping to prevent pool chemicals from evaporating into the atmosphere. This cover, a high-quality product made in Great Britain, greatly reduces humidity levels and the heating costs of indoor pools.
The black cover is ideal for keeping sunlight away from pool water and stopping algae growth in the water. Like any other type of cover, solar covers also prevent anything from entering the water, reduce dirt and the need to use additional chemicals for cleaning or the pool. The opposite reflective silver material helps prevent solar rays from escaping the pool, silver reflects heat inward, allowing the pool to heat up more than, for example, a blue sun cover. In addition, when the pool is covered in this way, the risk of evaporation and the consumption of chemicals are reduced. The color and level of opacity allow for very fast heat absorption, which will heat the pool faster than the other covers mentioned above.
By covering the pool with this material, evaporation is reduced by more than 98%, which translates into water conservation and the temperature.
