A lot of information about pool heating is either incorrect or portrays a negative view of the industry. One popular myth is that, when using solar pool heating, you only need 60% collector coverage to efficiently heat the water to a comfortable temperature. The total area of the solar collectors should be at least 80%, if not 100%, of your pool’s surface area. Anything less than 80% will mean that your pool will be inadequately heated. Many factors influence the design of a solar pool heating system. These include location of house and pool, trees and other structures causing shade over the collectors and pool, climate. All of these factors influence the size of the collector system required to sufficiently heat your swimming pool.
