As you put a bubble pool cover on the surface of water, the bubbles facing downwards trap the heat that comes from sunlight and transfer it to the water. So the pool cover itself becomes a heating device: and a sustainable one, too! It reduces your energy costs as you don’t need to use electricity or gas to keep the water warm. The sunny weather will do it for you.
You can choose to install a pool cover reel to unroll the pool solar blanket when the pool is resting and roll it back up when it’s time for the next splash. Alternatively, you can spread the pool blanket manually and leave it on for longer if necessary. In any scenario, it will be harnessing the power of the sun and retaining the warmth of the water.
