* All calculations are estimates. Actual results may vary due to a range of factors including, but not limited to: environmental conditions, pool type/construction/materials/configuration, geographical location, installation details and various operational parameters. Cost savings estimates are based on 65°F air temperature and 82°F water target temp for an uncovered pool operating 180 days under moderate wind conditions and the cost of natural gas is $1.22 per 100,000 BTU and comparing energy use to a gas heater that is 82% efficient. For assistance with sizing and selecting a pool heating product, please consult a swimming pool professional.
