WaterFurnace International introduced the 5 Series 504W11 hydronic geothermal heat pump, featuring the company’s patent-pending OptiHeat vapor injection technology.
While most hydronic geothermal systems generate 130°F water, OptiHeat creates exiting water temperatures up to 150°F via an additional heat exchanger that diverts excess heat and reinjects it into the system. This provides increased heating capacities and greater efficiencies, says WaterFurnace.
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.
