What is a Solar Blanket and How Does It Work?

May 03, 2021

Every pool owner knows the importance of having a pool cover. It’s essential for keeping dirt and debris out of the pool and making pool maintenance much easier. There are so many types of pool covers available, it can be tough to choose the right one for you. Lately, one option that’s become more popular is the solar blanket. But exactly what is a solar blanket and how does it work? We’ll explain!

What is a solar blanket? 

A solar blanket is a pool cover that basically looks like a giant sheet of bubble wrap. This cover sits on the surface of your pool water and uses the sun’s rays to warm your pool water.

Solar blankets come in many shapes and sizes and vary in thickness. They can be completely customized to suit your pool. 

How does it work?

The bubbles in a solar cover are actually thermal bubbles that grab UV rays from the sun. As they soak up that heat during the day, it traps the warmth in the bubbles during the night and helps to maintain your pool’s temperature. This is especially effective when you keep the solar blanket on as much as possible when nobody is using the pool.

Yes, your pool will naturally gather heat during the course of the day, but it’s not typically enough to keep it consistently warm during cooler seasons. Just like when you’ve heated water on the stove, you put a lid on it to lock in the heat. In much the same way, a solar blanket will prevent heat from being lost overnight or in cooler weather. 

Benefits of a Solar Blanket

Using a solar blanket saves you both energy and money. When the heat for your pool is coming from Mother Nature, you’re using the most efficient way to heat your pool. Not to mention, it’s cost effective when you’re not using energy to run an electric heat pump or gas pool heater. If you’re not using energy, your costs will obviously decrease. And who doesn’t love a lower utility bill?  

A solar blanket can also minimize evaporation. On average, a pool can lose about two inches of water each week. While not a lot by itself, it can add up to over 10,000 gallons of water lost over the course of the pool season each year. A solar blanket helps with controlling evaporation so that you don’t find yourself topping off your pool water quite as often.

Water isn’t the only thing your pool loses to evaporation. Chemicals can also be reduced when evaporation happens or when they’re diluted due to new water being added to replace what was lost. A solar blanket prevents loss of chemicals from your pool water, which will also save you money in the long run.
