WaterFurnace - Model 5 Series 504W11 -Single Hydronic Unit with OptiHeat Technology
The 5 Series represents some of our best features and efficiencies. The 504W11 is a single stage hydronic geothermal heat pump with OptiHeat technology that`s used for high temperature water-to-water applications.
Many 5 Series 504W11 owners use their unit to provide hot water for radiant heat. These systems offer exceptional comfort without moving air. Not only is the floor kept toasty warm, but the entire floor radiates heat to the occupants, furnishings and the air.

5 Series 504W11 units with OptiHeat vapor injection technology are capable of delivering up to 145 degree leaving hot water, which makes it the perfect solution for baseboard or cast iron radiation heating.
For large demands of hot water or for 100% domestic hot water generation, a 504W11 is a great choice. This WaterFurnace unit allows three to four times the efficiency of an ordinary water heater.
OptiHeat Vapor Injection technology incorporates an additional heat exchanger that diverts excess heat and reinjects it into the system. This creates higher exiting water temperatures and optimum compressor operating conditions. Smaller loads are required and result in the ultimate in efficiency.
The 5 Series 504W11 can reduce water heating costs by as much as 60% per year. Ordinary boilers and water heaters operate at a fraction of the efficiency of the 5 Series. With skyrocketing costs of fossil fuels, savings potential will only increase.
