WaterFurnace International, Inc.’s 5 Series 504W11 hydronic geothermal heat pump features WaterFurnace’s patent-pending OptiHeat vapor injection technology. OptiHeat creates exiting water temperatures up to 150°F (66° C), due to an additional heat exchanger that diverts excess heat and reinjects it into the system. This provides increased heating capacities and greater efficiencies. OptiHeat is the first water to water heat pump for the North American market to feature vapor injection technology.

 

Offering efficiencies up to 16.1 EER and 3.3 COP, the 5 Series 504W11 is ideal for high-temperature applications, such as baseboard radiator systems, underfloor radiant applications, overfloor radiant applications, and fan coils. The units can operate in heating-only or heating/cooling modes.

 

The 5 Series 504W11’s cabinet is fabricated from heavy-gauge steel, while a professional-grade textured finish provides long-lasting protection. Control panels can be placed on either end, which allows piping to be located on the front or back and helps improve serviceability.
