*Figures based on a 1,000 square-foot, outdoor pool heated with an 80% efficient natural gas heater at $.80 per therm and uncovered for 8 hours per day.

If you’re replacing a gas pool heater, you can use the following formula to determine your annual cost savings with a higher efficiency gas pool heater model:

Current Annual Cost x [1 – (Current Efficiency ÷ New Efficiency)]

INSTALLATION AND MAINTENANCE

Proper installation and maintenance of your heat pump pool heater can optimize its efficiency. It’s best to have a qualified pool professional install the heater, especially the electric hookup, and perform complicated maintenance or repair tasks.

Read your owner’s manual for a maintenance schedule and/or recommendations. You’ll probably need to tune up your pool heater annually. Because of a heat pump pool heater’s many moving and electrical parts, it will probably require periodic service by an air conditioning technician.

With proper installation and maintenance, heat pump pool heaters can last 10 or more years.
