How is a solar pool heater installed?
Basically, we cut the return pipe in between the filter and pool, and re-route the water to go in and out of the solar panels. Use of a 3 way valve makes the operation simpler, although it can be done with two 2 way valves. A check valve is placed in line, to prevent water from doing “a loop”. In practice, most of the water should bypass the solar panels, and use a diverter valve to “divert” 10-20% of the water volume in and out of the solar panels. Installing on a roof or on a rack made at a 45 degree angle allows for better heat absorption. Installing solar panels on a roof can be dangerous, so use precautions to keep yourself safe. Installation next to a pool, or on a rack mounted onto a fence or free standing is a simpler affair and should take only a few hours.
