Product Overview

The Pentair GulfStream HE125-TA is a high-efficiency electric pool heat pump designed to provide both heating and cooling for residential swimming pools. Rated at 115,000 BTU under 80/80/80 test conditions, the HE125-TA combines a titanium heat exchanger, efficient scroll compressor, oversized evaporator coil, and digital controls to provide dependable year-round water-temperature management. Its reversible heat/cool operation is especially useful in hot climates where pool water may need cooling during peak summer temperatures.

Ideal For

• Residential pools needing both heating and cooling capability

• Warm-climate pools that can become excessively hot during summer

• Pool owners wanting electric heat-pump efficiency instead of combustion heating

• Automation-equipped pool systems requiring heater integration

Key Features

• Heat and cool operation automatically heats or chills pool water toward the selected temperature.

• 115,000 BTU heating capacity at standard 80/80/80 testing conditions.

• Titanium heat exchanger provides excellent corrosion resistance for properly maintained pool water.

• High-efficiency scroll compressor delivers reliable heat-transfer performance.

• Large 20 sq. ft. wrap-around evaporator coil increases available heat-transfer surface area.

• Digital diagnostic LCD display provides operating information and fault messages in easy-to-read language.

• UV-stable, rust-resistant ABS cabinet is designed for outdoor pool-equipment environments.

• Compatible with major pool automation systems.

• Larger, lower-RPM fan design helps reduce operating sound.

Benefits

The HE125-TA allows pool owners to extend their swimming season while also providing the ability to cool overheated water during extremely warm weather.

With a published COP of 6.0 at 80/80/80 conditions, the heat pump transfers significantly more heat energy into the pool than the electrical energy it consumes under those test conditions.

The titanium heat exchanger provides durability in demanding pool environments, while the ABS cabinet eliminates the rust concerns associated with traditional metal cabinets.

Compatibility

The HE125-TA is designed for outdoor swimming-pool applications and uses standard 2-inch plumbing connections.

Pentair specifies a water-flow operating range of 30–70 GPM. Existing circulation equipment should be checked to ensure adequate flow through the heat pump.

The unit can also interface with compatible pool automation systems. Specific automation wiring and control compatibility should be confirmed before installation.

Installation & Electrical Requirements

The HE125-TA operates on 208/230V single-phase electrical service. Pentair specifies a minimum circuit ampacity of 37 amps and a maximum breaker rating of 50 amps.

Because heat pumps involve high-voltage electrical service, refrigerant systems, water circulation, drainage, and required equipment clearances, professional installation by a qualified pool or HVAC technician is recommended.

Confirm Before Ordering

Verify:

• Available 208/230V single-phase electrical service

• Proper circuit capacity

• 2-inch pool plumbing

• 30–70 GPM system flow

• Adequate outdoor equipment-pad clearance and airflow

• Pool size and desired heating/cooling performance

Specifications

Customer Q&A

Does the HE125-TA both heat and cool the pool?

Yes. Unlike GulfStream RA heat-only models, the HE125-TA provides reversible heating and cooling operation.

What is the current BTU rating?

Pentair currently rates the HE125-TA at 115,000 BTU under 80°F air, 80% relative humidity, and 80°F water test conditions.

Can it work with pool automation?

Yes. Pentair states GulfStream heat pumps are compatible with major pool automation systems. Verify the specific controller and required connection method before installation.

What size plumbing does it use?

The HE125-TA uses 2-inch plumbing unions and requires approximately 30–70 GPM of water flow.

Warranty

Pentair currently publishes a 7-year parts warranty and 2-year labor warranty for GulfStream heat pumps. Coverage is subject to current Pentair warranty terms, registration requirements, installation conditions, and exclusions.
