Solar Covers heat your pool in two stages: first by absorbing solar energy to heat the pool, and then by retaining the heat to keep the water warmer longer. The small bubbles on the Solar Cover are filled with air that heats up when the cover is in the sun.
A solar heater, as the name implies, is a mechanism that uses heat from the sun to warm up your pool water. Thin tubes, often made of black plastic, are arranged in either a coil or grid formation. Water is pumped through the solar tubing, and the sunâs heat warms it up.
