Here is an interesting product for swimming-lovers, especially with the winter approaching. These are the floating rings that collect and use the solar energy to raise the temperature of an average-sized pool by 3-4 per week. Hence it is not only energy-efficient, but also removes the hassles of electrical heaters or the effort required to place, remove, and store traditional tarp covers. And, it can dot he job by covering just 70% of the water surface.
It addition to that, each of these rings also acts as a partial barrier, slowing the water and chemical evaporation, thus, also reducing heat loss at night. Grab some before the winter sets in and enjoy your weekend afternoons in the pool.
