  • Stainless Steel
Evaporator Coils
  • Large Air Coils
    Raised lanced-fin design maximizes heating at lower temperatures. Raypak engineered coils are highly optimized to meet our specific design requirements. From the proper fins per inch to advanced distribution circuiting. We are the only heat pump pool heater company to actually manufacture our own coils.
  • Venturi Fan Cowling
    High-capacity 3000-cfm 825 RPM fan provides unrestricted air flow for better heating. Precision engineered and manufactured cabinet design eliminates unwanted air gaps. This means more air over the coil which translates to greater efficiency
  • Scroll Compressor with Cover
    Scroll compressors are quiet and efficient compared to piston-type compressors. They provide higher efficiency, lower sound levels, superior durability and unsurpassed reliability, with an added cover to further reduce noise. The unique design of a scroll compressor actually wears in over time, not out!
  • Sound-Absorbing ABS Base
Heat Exchanger
  • Spiral Titanium Tube
    Our spiral titanium-tube heat exchanger provides a corrosion-free waterway that can withstand the abuses of harsh pool chemistry. The spiral tube helps reduce deposit build-up and increases efficiency by performing a “scoop-and-lift” action.
  • Internal Bypass Valving
    Automatically compensates for normal day-to-day changes in your pool’s hydraulics, maximizing heat transfer efficiency.
  • Plumbing Connections
    Offset 2” PVC union connections are included for ease of installation.
Controls - Digital
  • Pool/Spa Control
    Your digital heat pump pool heater can be set to have a different target temperature for your pool and your spa. This allows you to dial in just the right spa temperatures and never have to adjust it again. The pool can be set to a lower, more energy saving temperature.
  • Remote Compatible
    The digital heat pump pool heater can be easily controlled by most two-wire and three-wire remote systems.
  • On Board Diagnostics
    Tells the homeowner if there is a problem. Provides the service technician with detailed diagnostic information.
