The SunHeater® S240 is a high-performance DIY solar pool heater designed for pool owners who want more heating power and a longer swimming season without the expense of gas or electric heaters. Featuring two 2' x 20' solar collector panels for a total of 80 square feet of solar heating surface, the S240 captures free solar energy and transfers it directly to your pool water through your existing filtration system.
Ideal for above-ground pools and many inground pool applications, this DIY solar pool heater can help increase water temperatures by up to 6–10°F under favorable conditions while reducing heating costs to virtually zero. The modular design allows installation on the ground, a rack, fence, deck, or rooftop, making it a flexible solution for a wide variety of backyards.
Constructed from durable UV-resistant materials and proudly made in the USA, the SunHeater S240 delivers reliable performance season after season. Whether you're looking to swim earlier in the spring, later into the fall, or simply enjoy warmer water all summer long, the S240 provides an affordable and environmentally friendly pool heating solution.

* IMPORTANT: For rooftop installations or inground pool applications, SunHeater should be connected to your pool equipment with rigid 1-1/2" Sch. 40 PVC piping, not cuffed pool hose. The S240U kit includes adapters for connecting to cuffed hose; in order to adapt to PVC, two 1-1/2" MPT x Slip adapters (not included) will be required.
