The HeatWave SuperQuiet® SQ166R comes equipped with all standard features. The Patented ThermoLink® Titanium Heat Exchanger at its core makes this unit a power-house that’s built to last. The SQ166R features IceBreaker® technology which allows you to heat and cool your pool. Plus, IceBreaker® units extend the swimming season longer than any other heat pump by continuing to operate in low temperatures.
