AquaCal Pool Heaters

AquaCal is a heat-pump specialist rather than a full pool equipment manufacturer, and that focus is the most useful thing to know about the brand. The company builds in St. Petersburg — the brochure carries the 2737 24th Street North, St. Petersburg, Florida address and the line "Producing quality heat pumps since 1981" — and it sits inside the employee-owned Team Horner group. For a Gulf Coast pool that means the factory is across the bay rather than across the country.

The residential line-up is led by HeatWave SuperQuiet, which AquaCal markets as its top-selling heat pump: SQ140R at 114,000 BTU/hr and SQ200R at 138,000 BTU/hr at the 80/80/80 test point, with the SQ160R between them, all covered by the same current national warranty. Below it sits the TropiCal family (T60, T70, T100 and T130), the HeatWave HW160R, and the TropiCool chillers (TC1000 and TC1500) for owners who want cooling only. SunPower, Water Source and the commercial Great Big Bopper round out the catalog, each with its own warranty document.

Two pieces of engineering define the brand. The first is the ThermoLink heat exchanger — patented, pure titanium, and designed so that it adds only 2 PSI of pressure drop at 45 gpm, which is what lets a variable-speed pump run at lower RPM while the heater is on. The second is PoolSync: the Wi-Fi antenna is embedded in the unit, so app control of heating, cooling and autotemp modes, remote diagnostics and real-time performance monitoring work with no added hardware, and a PoolSync Relay Center can take over the rest of the equipment pad. The SuperQuiet control itself is a weather-protected panel with a 24-character full-text display rather than a numeric code readout.

For Florida buyers, AquaCal's ICEBREAKER heat and cool option answers the late-summer complaint that northern pool owners never have, and the corrosion-proof cabinet with louvered panels over the evaporator coil is built for salt air. The warranty is the other reason the brand scores well here: three years of parts and labor, two more years of limited parts on the compressor, heat exchanger and evaporator coil, and a lifetime part-only warranty on the titanium tubing itself. None of it depends on PoolSync any longer — the 2025 document made the third year conditional on connecting the unit to the app within 30 days, and the 2026 documents dropped that. All of it depends on buying through an authorized dealer and having claims authorized in advance.
