Solar pool heaters

Plan the decision before comparing equipment

Solar pool heating is a surface-area and solar-access problem. Measure the water surface, map the roof or rack area that receives useful sun, and note how far and how high the system must move water. Collector orientation, shading, wind, pump head and freeze strategy can matter more than a package label. The guides below separate collector sizing from installation constraints so a large-looking kit is not mistaken for a complete design.
