Pentair Heat Pumps

Heat pumps are a great choice if you're looking for an energy-efficient way to heat your pool. They work by pulling heat from the surrounding air and transferring it to your pool water. While they take a bit longer to heat up, they can help you maintain a steady water temperature without breaking the bank.

Popular Models We Carry:

Why Choose a Heat Pump?

  • Energy-efficient operation, making it cost-effective over time.
  • Works best in warm climates with temperatures above 50°F.
  • Ideal for maintaining consistent temperatures over an extended period.

If you're looking for quick heating, a Pentair pool heater might be the better option. These heaters run on natural gas or propane, allowing them to warm up your pool much faster than a heat pump—perfect for those cooler months or when you need your pool ready in a hurry.

Which Option is Right for You?

Choosing between a heat pump and a heater depends on a few factors:
