Product Description


All of the HeatWave SuperQuiet® Heat Pumps are fully tested and certified by AHRI. Making the right choice just got a whole lot easier. Some of the HeatWave SuperQuiet® models are ICEBREAKERS®, which heat and cool the pool. The ICEBREAKER®units extend the swimming season longer than any other heat pump by continuing to operate in low temperatures.


The only heat pump that allows you to maximize the potential savings of a variable speed pump is an AquaCal®, which utilizes our patented ThermoLink® Heat Exchanger technology with its unique flow characteristics.

  • Patented hydraulic design adds only 1 PSI at 30 gpm, increasing compatibility with two-speed & variable speed pumps.
    Saves money when using a variable speed pump by reducing the RPM needed to achieve the same flow rate.
    Save money in a single speed pump application by reducing the run time needed to achieve the same turnover rate of the pool.

i have a old aqua cal heat pump and it never did the job of warming the pool water in a reasonable amount of time.Also had many break downs on it as to now its been disconnected for some years now. My pool guy just suggested the SQ166R for a heater. We have a 30,000 gallon pool that is in the shade most of the day. What are your thoughts?

A  Answered on 7/14/2018 by InyoPools Product Specialist Lennox H.

Hi, Bob. This unit is a great unit and AquaCal is a highly reputable company. To confirm if this unit will be adequate to heat your pool to your needs, use the AquaCal Sizing Estimator to enter in all variables.

Hi! What is the best way to find a plumber and electrician to install a heat pump? Also on the AquCal heat/cool pumps will it void the warranty if anyone other than an authorized distributor installs it?

A  Answered on 4/16/2020 by InyoPools Product Specialist Hector F.

You can locate a CPC(certified pool contractor) in your are online and these heat pump manufacturers do advise these units are installed by a qualified technician or the warranty may be voided if there is ever an issue with the unit.
