AquaComfort ACT-1750R Signature XL Pool Heat Pump, 143K BTU, Factory Refurbished
Big-pool heat at refurbished pricing.
The AquaComfort ACT-1750R (SKU PST-ACT1750R) is the factory-refurbished version of AquaComfort's flagship Signature XL 143,000 BTU in-ground pool heat pump, rebuilt and bench-tested by the manufacturer to deliver the same performance as a new unit at a meaningful discount. You get a scroll compressor, a TurboGuard titanium heat exchanger, and AquaComfort's low-ambient design that keeps heating when other pumps shut down. It is built for serious pool owners who want the longest possible swim season without the operating cost of a gas heater.
TurboGuard Titanium Heat Exchanger
Pool chemistry is brutal on heaters, and standard cupro-nickel coils corrode out long before the rest of the unit. The ACT-1750R pairs the scroll compressor with a TurboGuard titanium heat exchanger that shrugs off high chlorine, low pH, and salt-system water. AquaComfort backs this exchanger with a lifetime warranty on the new units it is built from, so the refurbished ACT-1750R inherits the same corrosion-proof core that lets these heat pumps run 10 to 12+ seasons.
Heats When Others Quit
Most pool heat pumps stop producing usable heat once the outside air drops below the low 50s. The Signature XL is engineered to keep heating down to 40F ambient, which adds real swim days at the front and back of the season. AquaComfort rates this platform to deliver 30 to 40 percent more heat than similarly sized competitors in the critical first and last 30 days of the season, turning your pool from a summer-only investment into a spring-through-fall asset.
Big Pool Power Without the Gas Bill
At 143,000 BTU output and a 6.0 COP efficiency rating, the ACT-1750R produces roughly six units of heat for every one unit of electricity it consumes. Compared to a gas heater of similar size, that means you can heat a large in-ground pool, a long lap pool, or a heavily used family pool for a fraction of the operating cost, with no propane tanks, no gas line, and no combustion exhaust to vent.
Who It's For
Large In-Ground Pools
Sized for residential in-ground pools in the 20,000 to 40,000 gallon range, including kidney, rectangle, and freeform shapes.
Long Swim Seasons
Ideal for owners who want to swim from April through October in temperate climates without paying gas-heater fuel bills.
Salt Chlorinated Pools
The titanium heat exchanger is built for salt water and aggressive chemistry, making it a natural fit downstream of a salt cell.
Replacing Tired Gas Heaters
A direct swap for owners stepping off propane or natural gas who want predictable monthly heating costs and lower lifetime maintenance.
Why PST Customers Pick This
Scroll Compressor
Fewer moving parts than a reciprocating compressor means quieter operation, better reliability, and a longer service life.
50 Amp Service
Runs on a 230V single-phase circuit with a 50 amp minimum breaker, standard residential service in most regions.
20 to 70 GPM Flow
Wide flow window works with most variable-speed and single-speed pumps without a separate bypass loop in many installations.
Built in the USA
Designed, built, and refurbished in the United States by AquaComfort, with parts and service support based in the US.
Factory Bench-Tested
Each refurbished unit is rebuilt to factory spec and run-tested on the bench before it ships, so it arrives ready to install.
Refurbished Value
Same Signature XL performance as a new unit at a lower price point, ideal if you want flagship capacity on a tighter budget.
Installation Notice
The ACT-1750R is a hard-wired 230V single-phase appliance and must be installed by a licensed electrician on a dedicated 50 amp circuit, with bonding and GFCI protection per NEC 680. Improper wiring, undersized conductors, or missing bonding can cause compressor failure, energize pool water, and will void the warranty.

Frequently Asked Questions
What does 'Factory Refurbished' mean for the ACT-1750R?
The R suffix means the unit was returned to AquaComfort, rebuilt to factory specifications with new or inspected components, and bench-tested before shipment. You get the same Signature XL performance as a new ACT-1750 at a lower price, with a 1-year parts warranty and 90-day labor warranty through AquaComfort.
What pool size will the 143K BTU output heat?
The ACT-1750R is rated for residential in-ground pools roughly 20,000 to 40,000 gallons. Exact sizing depends on your climate, whether you use a solar cover, your target water temperature, and how many hours per day the heat pump runs. In warmer regions or with a cover, it can comfortably handle the upper end of that range.
How is the ACT-1750R different from the ACT-1750HC?
The ACT-1750R is heat only, refurbished. The ACT-1750HC is a heat-and-cool model that can also chill pool water in hot southern climates. Both share the 143K BTU Signature XL platform, but the HC version uses a reversing valve and additional refrigerant components for the cooling cycle.
What electrical service do I need to install this?
A dedicated 230V single-phase circuit with a 50 amp breaker minimum. Wire size is sized by the run length and your local electrical code. The unit must be bonded to the pool's equipotential bonding grid per NEC 680, and the disconnect must be within sight of the unit.
Will it work with my variable-speed pump?
Yes. The 20 to 70 GPM flow window covers most variable-speed pump heating schedules. Run your VS pump at a speed that delivers at least 20 GPM through the heater during heating cycles, typically the same speed you would use for chlorinating or running a salt cell.
Can I install this heat pump myself?
Plumbing is straightforward 2-inch PVC. The electrical work should be done by a licensed electrician who is familiar with NEC 680 pool bonding requirements. Improper wiring is the most common cause of early heat-pump failure and will void the AquaComfort warranty.
How long does an AquaComfort heat pump last?
AquaComfort rates the Signature XL platform for 10 to 12 or more seasons in normal residential service. The titanium heat exchanger does not degrade from aggressive pool chemistry the way older cupro-nickel exchangers do, and the scroll compressor has fewer wear surfaces than reciprocating designs.

Does what a small weed- eater would do it minutes versus an hour
Great product does exactly what was advertised to do.
I ordered the wrong part. Customer service was very helpful. I returned it and within the week my credit card was credited back. Excellent customer service policy.
There was a delay in shipping due to postal service. They sent another part right away.
New model 59303 works great, but too bad the last generation Balboa WiFi module 50350 became un-useable.
Exactly as advertised and super fast shipping and delivery
