This solar swimming pool film is placed directly on the surface of the water, inside the edges of your swimming pool, and can thus increase the temperature of the water in your swimming pool by up to 1°C, depending on the amount of direct sunlight. With PE bubbles all over its surface, heat is contained much longer. This is the cheapest way to heat your pool. At the same time, it helps reduce chemical consumption, as well as water evaporation. It is easily adapted for smaller sized pools. As it is lightweight, its installation and handling are very easy.
