Solar pool heating systems aren’t universal. When choosing a new system for your pool, you have to determine the proper system size to maximise its heating potential.
There are several factors you need to consider. Perhaps the most important is the size of your pool. The connection is pretty obvious: the larger your pool, the bigger (i.e. more powerful) your heating system should be. More water to heat up requires more power — not to mention keeping it warm for extended periods.
