Solar pool heating is the most cost-effective way to heat your pool, as it has an endless supply of free energy from the sun, has no monthly recurring costs, and has a low annual maintenance schedule. In review of annual and forecasted electricity and natural gas prices, it was found you could save nearly between $12,000 and $28,000 over a 15-year period by selecting a solar pool heating system over a natural gas heater or an electric heat pump. In addition, using thermal energy to heat your pool qualifies you for a tax credit through the State of Arizona*. You could reduce your tax debt by up to $1,000 just for heating your pool!
