  • The FHP RT Model is a heat pump system, so it can provide both heating and cooling in one single package. It uses an integral energy recovery wheel to provide, in FHP’s view, a “high quality, engineered alternative for 100% outdoor air applications.” This can be a better choice than relying on custom-built equipment.

  • The FHP RT Model features a coaxial water-to-refrigerant heat exchanger, chlorine-free R-410A refrigerant, refrigerant drier, serviceable refrigerant reversing valves, overload protected compressor motor, integral service/charging ports, hot gas bypass for low load control, and refrigerant accumulators for additional protection against potential compressor damage.


  • Rooftop units like the FHP RT Model can, depending on your climate, experience a lot of inclement weather. This can result in substantial corrosion, so be sure to factor that into long term cost calculations.

  • Rooftop applications are mostly relied upon when attempting to heat and cool a large interior space like a warehouse store. If you don’t fit the criteria, another type of HVAC system may be a better option.

Bottom Line

The FHP RT Model Rooftop Water Source Heat Pump is a medium range system specially designed for rooftop applications. Its reasonably energy efficient and comes with quality features. If you need a rooftop installation, this is not a bad choice.
