Inverter Heat Pumps for Swimming Pools

About

Inverter Pool Heat Pump Need a heater that keeps your pool warm without running up your electric bill? An inverter pool heat pump is the most efficient option on the market. We carry inverter models from AquaCal, Madimack, and Moov, with free shipping on every order. Pool Inverter Heat Pump A pool inverter heat pump pulls warmth from the surrounding air and transfers it to your pool water through a refrigerant cycle. The difference between an inverter and a standard heat pump is the compressor. Inverter models use a variable-speed compressor that modulates to match demand. Standard heat pumps run at one fixed speed and cycle on and off. That difference makes inverter units: Quieter at part-load speeds. More efficient at maintaining temperature. Longer-lasting with less compressor wear. Better in cold weather than fixed-speed units. How an Inverter Heat Pump Pool System Works An inverter heat pump moves heat from outside air into your pool through a refrigerant cycle: Fan draws ambient air across an evaporator coil filled with refrigerant. Refrigerant absorbs heat and changes from liquid to gas. Variable-speed compressor raises refrigerant pressure and temperature. Heat exchanger transfers heat from the refrigerant to the pool water. Refrigerant cools and condenses, then cycles back to start over. Because heat pumps move existing heat instead of creating it, they deliver four to seven units of heat per unit of electricity. Inverter compressors push that ratio higher by matching speed to demand. Inverter Pump Technology and Variable-Speed Operation A standard compressor runs at one fixed RPM set by AC line frequency (60 Hz in the U.S.). It shuts off at setpoint and restarts at full speed when water cools. An inverter converts AC to DC and back to AC at a controlled frequency, modulating compressor RPM continuously between low speed and full speed. The compressor never has to stop and restart. What that looks like in practice: Initial heat-up runs at high speed to brin
