The GulfStream HE110-RA is a high-efficiency pool heat pump designed to maintain comfortable swimming temperatures while using less energy than traditional electric resistance heating.
Rated at 110,000 BTU under 80°F air, 80% humidity, and 80°F water conditions, the HE110-RA combines a corrosion-resistant titanium heat exchanger, efficient scroll compressor, lower-RPM fan, digital controls, and pool-automation compatibility.
It is the most compact model in the GulfStream lineup and a strong heat-only option for residential pools with lower heating demands.

Heating Performance
The HE110-RA transfers heat from the surrounding air into the pool water to maintain the selected temperature.
Heat pumps are designed primarily for efficient temperature maintenance rather than the rapid temperature increase associated with gas heaters. Performance depends on air temperature, humidity, pool size, wind exposure, desired water temperature, and whether a pool cover is used.
Warmer and more humid outdoor conditions generally improve heating output and efficiency.

Titanium Heat Exchanger
The titanium heat exchanger provides strong corrosion resistance and is suitable for properly maintained conventional and saltwater pool systems.
Correct water chemistry and proper placement of chemical-feeding equipment are essential to protecting the heat exchanger and other pool equipment.
Quiet Operation
The HE110-RA uses an efficient scroll compressor, engineered fan blade, deep-drawn venturi, and larger low-RPM fan to help reduce operating sound.
Actual sound levels can vary based on installation location, surrounding walls, equipment-pad construction, and air recirculation.
Digital Controls
The built-in LCD control provides real-time operating information, water-temperature display, and access to heating settings.
Control features include:
- Pool heating mode
- Spa heating mode
- Separate pool and spa temperature settings
- Power-off mode
- Automatic low-temperature defrost
- Self-diagnostic fault display
- Keypad lockout
- Spa timer
- Remote-control capability
A built-in startup delay helps protect the compressor from rapid cycling.
Pool-Automation Compatibility
The HE110-RA can be operated from its onboard display or connected to a compatible pool-automation system using the unit’s external dry-contact controls.
Automation compatibility and wiring configuration should be confirmed before installation.
Only dry-contact, non-powered connections should be made to the external-control terminals.
Water Flow and Plumbing
The HE110-RA requires water flow between 20 and 70 GPM, with an optimal operating range of approximately 45–50 GPM.
The recommended plumbing sequence is:
Pool → Pump → Filter → Heat Pump → Solar Heating → Chlorination System → Pool
Additional plumbing requirements include:
- Use rigid PVC plumbing
- Install the heat pump after the filter
- Install chlorinators and saltwater chlorine generators after the heat pump
- Install a check valve between the heat pump and chemical-feeding equipment when needed
- Minimize unnecessary fittings and plumbing length
- Confirm correct inlet and outlet flow direction
- Maintain access to the control and service panels
- Use a bypass when system flow may exceed 70 GPM
- Adjust the pressure switch or install an external flow switch when required for below-water-level installations
The full-flow heat exchanger does not require an external bypass when water flow remains within the approved operating range.
Installation Requirements
The HE110-RA is designed for outdoor installation and requires unrestricted access to surrounding air.
Installation requirements include:
- Install on a flat, stable equipment pad
- Provide at least 12 inches of clearance around each side
- Provide at least 4 feet of unobstructed clearance above the unit
- Do not install inside a garage, shed, or enclosed equipment room
- Avoid locations where discharged air can recirculate through the unit
- Keep the control panel facing outward for operation and service
- Prevent roof runoff from pouring onto the unit
- Keep sprinklers directed away from the heat pump
- Keep corrosive pool chemicals away from the equipment
- Provide adequate drainage for normal condensation
- Install an electrical disconnect within sight of the unit
- Isolate the unit from building walls or foundations to reduce vibration transfer
Poor airflow, inadequate clearances, or cold-air recirculation can reduce performance and may cause unnecessary defrost operation.
Condensation
Water draining from the base of the unit during operation is normally condensation collected from the surrounding air.
The amount of condensation varies with humidity and operating conditions and can sometimes appear similar to a plumbing leak.
Proper drainage must be provided around the equipment pad.
Water Chemistry
Recommended water-quality levels include:
- pH: 7.4–7.6
- Free chlorine: 1–3 ppm for pools
- Free chlorine: 3–5 ppm for spas
- Total alkalinity: 100–120 ppm
- Total dissolved solids: Less than 2,000 ppm
- Calcium hardness: 200–400 ppm
Never place solid chlorine in the pool skimmer or introduce concentrated chemicals upstream of the heat pump.
Improper water chemistry, chemical feeding, or exposure to corrosive substances may damage the heat exchanger and other internal components.
Electrical Requirements
The HE110-RA requires:
- Minimum circuit ampacity: 37A
- Maximum breaker: 40A
- Dedicated electrical supply
- Proper grounding and bonding
- Code-compliant disconnect
- Installation by a qualified professional
Electrical service must match the unit rating plate. Wiring, conduit, disconnects, conductor sizing, overcurrent protection, grounding, and bonding must comply with the National Electrical Code and all applicable local requirements.
Warranty
The current GulfStream limited warranty provides:
- 7 years of parts coverage
- 2 years of labor coverage
- No trip charges for qualifying full-warranty repairs
Warranty coverage begins from the qualifying installation date and is subject to registration, authorized installation and service, proper water chemistry, maintenance, and all other GulfStream warranty terms.
Warranty service must be performed by an authorized service provider. Unauthorized repair may not be covered.
What to Confirm Before Ordering
Before ordering the HE110-RA, confirm:
- Pool volume and surface area
- Geographic location and seasonal climate
- Desired water temperature
- Expected swimming season
- Pool-cover use
- Available electrical service
- Water-flow rate
- Plumbing size
- Equipment-pad dimensions
- Required installation clearances
- Automation-system compatibility
Proper heat-pump sizing should account for more than pool volume alone. Wind exposure, nighttime temperatures, humidity, desired temperature rise, and heat loss can significantly affect performance.
Frequently Asked Questions
Is the HE110-RA heat only?
Yes. The HE110-RA is designed for pool heating and does not provide active water cooling.
What is its heating output?
The current published rating is 110,000 BTU under 80°F air, 80% relative humidity, and 80°F water test conditions.
What does a 6.1 COP mean?
Under the published 80/80/80 test conditions, the unit delivers approximately 6.1 units of heat for every unit of electricity consumed.
Is it suitable for saltwater pools?
Yes. The titanium heat exchanger is suitable for properly maintained saltwater systems. The salt chlorine generator must be installed downstream from the heat pump.
Does it include Wi-Fi?
Built-in Wi-Fi is not listed as a standard HE110-RA feature. The unit can be operated through its onboard control or connected to a compatible external automation system.
What water flow does it require?
The approved operating range is 20–70 GPM, with approximately 45–50 GPM identified as the optimal range.
Does it require a bypass valve?
An external bypass is not required when flow remains within the approved range. A bypass is required when system flow may exceed 70 GPM.
Can it be installed indoors?
No. It is designed for outdoor installation with unrestricted airflow and at least 4 feet of clearance above the unit.
Is water draining from the unit normal?
Yes. Condensation drainage is normal while the heat pump is operating, especially in humid conditions.
How quickly will it heat the pool?
Heating time depends on pool size, starting temperature, outdoor conditions, heat loss, and use of a pool cover. Heat pumps are intended to maintain temperature efficiently rather than provide instant heating.
