Pool & Spa

These pool and spa systems are purpose-built for residential and light commercial water heating. Whether you manage a small property, maintain a home pool, or handle multi-unit amenities, you’ll find Heat Only and Heat & Cool options to match your climate and usage. Models span budget-friendly price points from about $310 to $5,695, with pro installation recommended to meet code and warranty requirements.

Match capacity to your application with sizes around 115,000, 118,000, 125,000, and 142,000 BTU. Select units are available in 3 Phase 208/240v for light commercial service rooms. All featured models use R-410A refrigerant for dependable performance and broad service support. Note: SEER2 and HSPF2 ratings apply to space-conditioning HVAC and are not used for pool heat pumps; focus on BTU capacity, power requirements, and water flow specs instead.

Choose Heat Only to efficiently maintain a comfortable water temperature through most of the season, or step up to Heat & Cool (reversible) to chill water during heat waves and protect specialty pools and spas from overheating. These systems are ideal for replacing aging pool heaters with efficient R-410A technology while keeping operating costs low and runtime quiet.

Frequently Asked Questions

  • What BTU size pool heat pump do I need for my pool or spa?

    Size by pool surface area, climate, wind exposure, and desired temperature rise. Many residential pools fit 115k-142k BTU. Choose the higher BTU for windy sites, extended seasons, or spa duty.

  • What is the difference between Heat Only and Heat & Cool pool heat pumps?

    Heat-only units warm the water. Heat & Cool (reversible) models can also chill, helping prevent overheating in hot climates or for therapy and specialty pools.

  • Can these GulfStream pool heat pumps operate on 3 Phase 208/240V power?

    Yes. Select models are built for 3 Phase 208/240v. Verify the nameplate voltage and phase, and have a licensed electrician make the connection.

  • Do these units use R-410A refrigerant and what are the implications for service?

    They use R-410A. Any refrigerant work must be done by an EPA-certified technician. R-410A support remains widely available despite the industry phase-down.

  • Are these pool heat pumps suitable for residential vs light commercial pools?

    Yes. Capacities up to about 142,000 BTU suit many residential pools and small commercial amenities, provided electrical and flow requirements are met.

  • What maintenance is required for a pool heat pump to maintain performance?

    Keep the evaporator coil clean and unobstructed, maintain proper water chemistry and filtration, check flow rates, and winterize per the manual in freezing climates.

  • What installation considerations are there for electrical service and plumbing?

    Provide a dedicated circuit, correct breaker and disconnect, bonding/grounding to code, a level pad, clear airflow, and PVC plumbing with a bypass if flow is high.

  • How do operating costs of a pool heat pump compare to gas heaters?

    Heat pumps typically deliver a COP around 4-6, often costing 50-70% less to run than gas for maintaining temperature, though they heat more gradually.

  • Can a DIY homeowner install a pool heat pump?

    We recommend professional installation. Licensed electrical and plumbing work protects safety, ensures code compliance, and preserves manufacturer warranty.

  • What ambient temperature range do these heat pumps work in?

    Most operate efficiently down to about 45-50°F ambient, with defrost protection. Performance improves as outdoor temperatures rise.
