Introducing the World’s Most Efficient Swimming Pool Heat Pump.

AquaCal’s advanced variable speed heat pump technology will automatically adjust its speed, precisely matching the heating demand to maximize efficiency.

The smart technology calculates the speed required to sustain the desired pool temperature in the runtime allotted. This approach cuts heating cost up to 40% more than a single speed heat pump.

C.O.P.s can reach as high as 10.5 or higher, making it the most energy efficient heat pump available!

PoolSync Ready

Now you can control your heat pump right through your smartphone. Change the mode to heat, cool or autotemp, and set your temperature through the PoolSync app.

  • The investment of the Variable Speed Heat Pump versus a single speed heat pump can be recouped in energy savings in less than 3 years.
  • Running at reduced speed lowers wear on the compressor, extending its service life.
  • Pair it with a variable speed pool pump to achieve the highest efficiency pool system possible.
