Florida-Built Pool Heat Pumps: GulfStream vs AquaCal vs Built Right

GulfStream heat pumps are built by G&F Manufacturing on Interstate Court in North Fort Myers, according to the installation manual Pentair hosts. The brand is now part of Pentair Pool: the old gulfstreamheatpump.com address redirects to Pentair, and Pentair states that warranty, service and technical support are managed by Pentair. So a GulfStream is Florida-built, but the company behind the warranty is a national one.

AquaCal AutoPilot builds in St. Petersburg. Its HeatWave SuperQuiet brochure carries the 2737 24th Street North address and the line "Producing quality heat pumps since 1981", and the company makes heat pumps rather than a full range of pool equipment. Built Right says its heat pumps are manufactured locally in Punta Gorda, that most service work in Florida is provided by factory technicians, and that it offers a 24 to 48 hour warranty response time. It sells to licensed contractors only, with no direct sales to the public.

One detail worth knowing about Built Right: its current warranty page is issued in the name of Zodiac Pool Systems LLC, a Fluidra company. We report that as it appears on the page; Built Right's own pages describe the manufacturing and service as local to Punta Gorda.

On the numbers that usually lead a sales conversation, the three are close. Each offers a unit around 110,000 to 118,000 BTU/hr and one around 135,000 to 138,000 at the 80/80/80 test point, each uses a titanium heat exchanger, and each houses it in a cabinet built not to rust: UV-stabilized ABS on the GulfStream, a corrosion-proof, impact-resistant cabinet with louvered side panels on the AquaCal, and a corrosion-free, UV-resistant polymer housing on the Built Right.

The differences are in what each publishes and offers. AquaCal and Built Right publish capacity at 50°F air; GulfStream publishes only that every HE model meets or exceeds a COP of 4.0 at that test point. All of AquaCal's SuperQuiet models heat and cool, while GulfStream and Built Right each sell heat-only and heat-and-cool versions. GulfStream publishes minimum circuit amps and maximum breaker for every model; Built Right's manual tells the installer to read the breaker size off the unit's data label.

This is where the three really differ, and where reading the documents matters more than reading the brochure. The table states each manufacturer's published terms and conditions; we have not ranked them, because the right structure depends on what you are protecting against.

GulfStream's sell sheet promises a no-nonsense warranty with no charges for full-warranty repairs, no trip charges, and parts warranted for 7 years from installation. The catch is inside Pentair's own paperwork: its cross-brand warranty table lists GulfStream Heat Pump at 2 years and GulfStream Heat Pump (Parts) at 3 years, which we could not reconcile with the sell sheet. Pentair's warranty page also states that equipment bought from an internet retailer gets one year of parts only, with no labor.

AquaCal's discrepancy is about call-out fees. Its two 2026 documents disagree: LTP0159 Rev. H, the one linked from aquacal.com, states a trip charge applies for service performed after year 1, while the April 2026 warranty card LTP19255 Rev A states trip and shop supply fees are waived during years 1-3 and may apply in years 4-5. Neither makes coverage conditional on connecting the unit to PoolSync, which the 2025 document did. Built Right's discrepancy is geographic: the current warranty page says the 50 United States, while the warranty sheet bound into the 2017-2018 owner's manual applies to models installed within the State of Florida, and that manual sheet adds a registration form within 30 days, prior authorization for every claim and repairs by a Factory Authorized Service Agent.

On capacity they meet in the middle: the GulfStream HE150-RA and AquaCal SQ200R are both rated 138,000 BTU/hr at 80/80/80, with COPs of 6.0 and 6.1. Below that, the HE110-RA and HE125-RA bracket the SQ140R's 114,000 BTU/hr. The electrical demand differs a little: 37 A minimum circuit amps on the GulfStream RA models, 38.5 A on the SQ140R and 42.1 A on the SQ200R.

Controls are the clearest difference. AquaCal builds PoolSync Wi-Fi into the unit, with app control of heating, cooling and autotemp modes and remote diagnostics, and the heater can also take a heating or cooling signal from an external controller. GulfStream publishes no app or Wi-Fi, and its manual states the heat pump cannot be connected to automation over RS-485; it connects by dry contact only. AquaCal also designs its ThermoLink exchanger around low flow, publishing a pressure drop of only 2 PSI at 45 gpm, which suits a variable-speed pump running slowly while the heater is on.

Heat and cool comes standard across the AquaCal SuperQuiet line; at GulfStream it is the TA models only, which give up a little heating capacity to the RA versions and cost more. On price, GulfStream's heat-only models sit in the mid-range tier on this site and AquaCal's SuperQuiet in the upper mid-range. Put simply: GulfStream for a straightforward heat-only unit with a long parts term, AquaCal for built-in connectivity and heat-and-cool from a heat-pump specialist, with its trip-charge wording read carefully.

These two are the closest match on paper. The GulfStream HE150-RA is rated 138,000 BTU/hr at COP 6.0 and the Built Right BR135XW 135,000 BTU/hr at COP 6.0; the smaller GulfStream HE110-RA (110,000, COP 6.1) sits near Built Right's BR115XW (117,000, COP 6.5). Both offer a heat-and-cool version (GulfStream's TA models, Built Right's BR135XW H/C), both use titanium in a non-metallic cabinet, and both enter defrost below 48°F; GulfStream states its units will not operate below 35°F, and Built Right's manual advises against running below 45°F.

The warranty is the real choice. GulfStream publishes 7 years of parts and 2 years of labor; Built Right publishes 5 years of parts and 5 years of on-site labor. Which suits you depends on whether you would rather be covered for a part failing in years six and seven, or for the labor bill on a repair in years three to five. Each has conditions: GulfStream's warranty runs through an authorized service center and is contradicted by Pentair's cross-brand table, and Built Right's has the Florida-versus-50-states wording and the registration and authorization requirements in its manual sheet.

Neither has an app. GulfStream connects to automation through dry-contact remote thermostat terminals; Built Right through two remote wires for a pool/spa remote or remote thermostat. Installation details differ slightly: GulfStream asks for 12 inches on each side and four feet above, Built Right six inches on all sides, four feet above and 24 inches at the control panel. You will buy either through a professional: Built Right sells only to licensed contractors, and Pentair's full GulfStream term depends on buying from a pool professional or retailer with paid professional installation.

Because all three have something in their paperwork worth clarifying, these are the questions we would want answered in writing before a unit is ordered. None of them is a reason to rule a brand out; they are a reason to know exactly what you are buying.

Write the answers on the quote. If a warranty claim ever comes up, the document number and the name of the servicing agent are the two things you will be asked for first.

GulfStream is the Florida-built brand we can speak to from our own pads. Our project library includes GulfStream HE150-RA installs in Dunedin, Tampa, Siesta Key and Treasure Island and an HE110-RA in Punta Gorda, all with the model read off the data plate, and one of the GulfStream jobs in our gallery was for a customer who specifically wanted a locally manufactured heater.

Our project library does not yet include an AquaCal or a Built Right install, so for those two brands this comparison is built from the manufacturers' documents rather than our field experience, and we say so. We are not claiming authorized-dealer status for any of the three. What we can do is look at your pool, your pad and your panel and tell you honestly which of them fits, along with the national brands.
