Frequently Asked Questions (FAQs)

1. Is solar pool heating worth it?

You can significantly reduce swimming pool heating costs by installing a solar pool heater. They're cost competitive with both gas and heat pump pool heaters, and they have very low annual operating costs. Actually, solar pool heating is one of the most cost-effective use of solar energy in some climates.

2. How much will a solar heater heat my pool?

Right now, an unglazed solar system can heat a pool to 78-85 degrees Fahrenheit without much effort. Solar pool heating panels last about 20 years, so in that scenario you could be looking at about 17 years of cost savings.

3. How long does a solar pool heater take to heat a pool?

It takes an average of 15 hours to heat a 10,000-gallon pool, which is the quickest way, but also the most expensive. If you are operating an Electric Pool Heat Pump it would take 2 days to reach 10 degrees and 5-6 hours of operation.
