Pentair's pool heat pumps are dependable, easy to use and budget-friendly. And while both gas pool heaters and pool heat pumps achieve the same goal - warm pool water - they both work differently.
Swimming pool heat pumps use electricity to circulate a refrigerant through the unit to extract free heat out of the air. They extract the heat using the thermodynamics of evaporating and re-compressing refrigerants. This process uses less electricity than it would take to produce the same amount of heat with an electric heating element. With a pool heat pump there is no need to install a gas line. And a heat pump pool heater does not release any emissions.
Pool heat pumps are popular in many climates and are for pools and spas where the goal is temperature maintenance, as opposed to fast heat-up.
