Selecting the Ideal Pool Heating System for Your Pool
Discover how to select the perfect pool heater to ensure year-round enjoyment. Learn about sizing, energy sources, and budget considerations for replacing or installing a new pool heating system tailored to your needs. Keep your pool comfortable and functional regardless of the season.

An in-ground swimming pool is a fantastic feature for any home, offering fun and relaxation during warm months. As colder seasons approach, its usability can decrease. Installing a pool heater allows you to enjoy your pool all year round, expanding usage beyond the summer and maintaining its value and comfort during chilly weather.
1. Determine if you need a new unit or a replacement
Are you purchasing a brand-new heater or replacing an existing one? If replacing, ensure the new unit matches the current setup by measuring and noting specifications to prevent size or compatibility issues. For new installations, consider the extra costs for professional setup and plan your budget accordingly.
2. Select based on your pool's dimensions and desired temperature
The pool heater size should correspond to your pool’s volume and your preferred water temperature. Larger pools need bigger heaters, which can increase costs for purchase, installation, and operation. Achieving higher water temperatures also requires more powerful units, so size accordingly.
3. Choose the appropriate energy source
Your available backyard power sources influence your choice of heater. Options include natural gas, propane, electric, solar, and heat pumps. Modern trends favor solar, heat pump, and electric heaters over traditional gas and propane systems due to efficiency and environmental benefits.
