Battle of the Solar Covers Solar Blanket vs. Liquid Solar Cover

When looking for ways to conserve money and resources while maintaining a pool, liquid solar blankets are commonly overlooked. To put it simply, a liquid solar blanket is an evaporation suppressant. The liquid solar blanket is often compared to putting a lid on a boiling pot of water.  It creates an invisible barrier on the surface of the water and helps to control the rate at which the vapour escapes from the pool. Liquid solar blankets are not meant to heat your pool or replace your heater, they simply retain the radiation from the sun therefore keeping the water warmer for longer and allowing for less water to evaporate. Less evaporation of course means having to add water to the pool less frequently, resulting in cost and energy savings.

 

When evaporation occurs, only pure water leaves. This of course means the water left in the pool will have a higher TDS reading and higher calcium hardness. If the source water one is filling their pool with has metals or phosphates, that is another potential expense to the pool owner as getting rid of metals and phosphates ends up costing money for labour and of course chemicals.

 

When Evaporation Occurs Most in Your Pool
  • Pools with a large surface area are more susceptible to water evaporation
  • If your water temperature is higher than surrounding air
  • Windy conditions
  • Humid environment
  • Strong radiation from the sun

 

Now you might be asking yourself why you would use a liquid solar blanket rather than a physical solar cover. One of the biggest reasons simply comes down to the size and the storage required to keep a solar blanket in good condition. Simply, the solar blanket distracts from the beauty of the pool! Some pool owners are even convinced they use their pool less because they dread having to deal with their solar blanket every time they get in and out of their pool. On the other hand, the liquid solar blanket continues to work when bathers are in the pool. As the tension formed at the surface of the water is broken by the bather but reforms quickly.

 

How to Use a Liquid Solar Blanket
  • With circulation running, add product to the skimmer (this disperses the monomolecular layer on the surface of the water)
  • If desired, use physical solar blanket and liquid solar blanket at the same time for double the protection
