Solar Pool Heating

“Solar pool heating is the most cost-effective use of solar energy.”

Residential Pools: Swimming in the Warmth of the Sun


Every year, nearly 140,000 solar pool heating systems are sold to residential pool owners.

Every year, nearly 140,000 solar pool heating systems are sold to pool owners who want safe, efficient solar pool heating.

Around the world, there are over 15 million residential and commercial swimming pools – about half of these are located in the U.S. Residential pool owners are looking to maximize their investment by swimming earlier in the spring and later into the fall. But gas and electric heaters are costly to operate and repair, contribute to pollution and consume our limited supply of natural resources.

Solar is the most cost-effective form of pool heating, with no additional operating costs, low maintenance and an endless supply of free heat from the sun. Solar can act as a standalone heater or in conjunction with an existing heater as a hybrid heating system.

Commercial Pools: The Perfect Candidate for Solar

Commercial swimming pools like those at hotels, resorts, apartment complexes, HOAs, health clubs, camps and schools are perfect candidates for solar pool heating, since owners and operators have no choice but to keep their pools at a comfortable temperature. According to industry statistics, two-thirds of the commercial pools worldwide have either seasonal or year-round heating requirements.

Most of these pools are heated with fossil-fuels such as natural gas, propane, or heat pumps. Aside from increasing these facilities’ operating costs, using fossil-fuels to heat swimming pools increases the United States’ dependence on imported fuels, and pollutes the air. Furthermore, fossil-fuel prices fluctuate significantly and are expected to rise over the next decade. Solar pool heating systems can provide a clean, domestic and affordable way to reduce the monthly energy bill for heating commercial swimming pools.

NSF-50: Required for Commercial Pool Equipment

Approval - NSF copy

Aquatherm is the only U.S. manufacturer of solar pool heating systems to meet the strict safety, durability, and toxicity standards required for NSF-50 certification, which is mandatory for commercial and recreational pool products in most of the United States.
