Solar Pool Heating FAQs

Will a solar pool heater really heat my pool?

Of course! Depending on your weather and climatic conditions, you can expect your FAFCO solar pool heater to:

  • Raise your pool temperature 2 to 5 degrees Fahrenheit each time the water passes through the system, and
  • Raise your pool’s temperature 5 to 15 degrees Fahrenheit over a period of several days of good weather

A solar blanket will help hold in this heat at night or when it’s windy, and can help the system be even more effective.

Can it also cool my pool?

During the hottest part of the summer, running the solar pool heating system at night can cool a pool to a more refreshing swimming temperature — down several degrees in one night if the conditions are right.

Can pool solar panels be used to heat the house?

No. Solar pool panels and controls are designed specifically to heat a large volume of water in a swimming pool, and to operate in temperature ranges of 80 to 100 degrees. Household space heating and household hot water are different applications of solar, requiring heating smaller volumes of household water to higher temperatures.

How much would a solar pool heater cost for my pool?

Solar pool heating system prices for a residential pool can range anywhere from $2500 to $7000. The location and size of the pool, location of the solar panels, desired temperature and season, and type of pool equipment determine system size and costs. Because of all the variables, it is impossible to give an accurate estimate without careful inspection of the site. To set up an appointment for a free analysis and estimate contact us.

Will a solar pool heater save me money?

If a pool owner heats their pool with natural gas through the normal swimming season, an investment in solar can pay for itself in 2 to 3 years. If the pool owner does not have a gas heater or wish to use one, solar will not really “save” money, but the pool will be much warmer and more inviting. A swimming pool, with decking and landscaping, represent a sizable investment for the homeowner. Maintenance costs exist whether the pool is used or not. The investment in solar pool heating will assure that the pool is used and enjoyed much more.

How much does a solar pool heater cost to operate?

The majority of residential solar pool heaters use an automatically controlled valve to divert the existing filtration flow to the solar panels, so there is no additional cost to operate the solar pool heater. Some pools might require an additional solar boost pump that would cost a few dollars per month to operate during the swimming season.

How long will the solar equipment last?

FAFCO solar collectors made of patented stabilized polypropylene can be expected to last between 20 to 25 years. Thousands of FAFCO solar pool heating systems that were installed over 20 years ago are still going strong, even in harsh climates such as Arizona and Florida.

Should I use a pool cover with a solar pool heating system?

With a properly sized solar pool heater, a pool cover is normally not required to keep the pool at a comfortable temperature during the normal swimming season. However, a pool cover does help retain heat at night and prevent evaporation loss. The cover traps the solar heat that has been added during the day, and is very complementary to the solar pool heating system. The solar pool heating system can be viewed as actively adding heat. The cover retains that heat passively.

What special maintenance is required on a solar pool heater?

Usually no special maintenance is required during the season. Modern electronic controls allow you to “set and forget” the solar heater. It is recommended that the panels be shut off and drained in the winter. SolarCraft offers this winterization service for a small fee.

What qualifications should I look for in a solar contractor?

Installers of new solar energy systems are required by the State of California Contractor’s License Board to be properly licensed and insured. The licenses required to install solar heating systems are C46 (solar), C36 (Plumbing) or B (General Building). Contractors holding only a C61, (pool maintenance), license cannot legally install new solar energy heating systems.

Contractors are required to have their license number on all contracts. The status of a license can be quickly verified at
