First, Gulfstream Is Now Part of Pentair

Gulfstream heat pumps were made by G&F Manufacturing, a Florida company. Pentair bought G&F Manufacturing in December 2024, so Gulfstream is now one of Pentair’s heat pump lines, alongside Pentair’s own UltraTemp heat pumps. In practice, that makes this a comparison of two Pentair lines and Hayward.

Gulfstream (Pentair)

Gulfstream built its name on heat pumps for Florida and the Southeast. Pentair lists a C.O.P. of 6.0 to 6.1 for Gulfstream’s HE models, a titanium heat exchanger, and a 7-year parts warranty with a 2-year labor warranty.

Pentair UltraTemp

Pentair’s UltraTemp heat pumps use a titanium heat exchanger and a scroll compressor, with heat and cool versions available. Pentair also makes the UltraTemp ETi hybrid, which combines a heat pump with a gas heater in one unit.

Hayward HeatPro

Hayward’s HeatPro heat pumps also use a titanium heat exchanger built to resist corrosion in saltwater pools and coastal air. HeatPro comes in several sizes, and heat and cool models are available.

What They Have in Common

All three brands:

Use titanium heat exchangers, which matters for saltwater pools and homes near the coast.
Offer heat and cool models, so the same unit can cool your pool in the summer.
Come in a range of sizes for residential pools.

The biggest differences are usually in the specific model: its size, its efficiency at the temperatures you actually swim in, its controls, and its warranty. Warranty terms come from each manufacturer and can change, so always check the current warranty for the model you are buying.

What About AquaCal?

AquaCal is the heat pump brand we install most often. AquaCal is made in St. Petersburg, Florida, uses its patented ThermoLink titanium heat exchanger, and offers the TropiCal heat and cool line and variable speed models that can reach a C.O.P. of 10.5 or higher.
