5 Series Hydronic Geothermal Heat Pump

Model 502W12

The 502W12 High Temperature Hydronic Heat Pump is our geothermal solution for boiler replacement. Capable of delivering 150°F leaving hot water, this system is perfect for baseboard radiator systems, under floor radiant applications, over floor radiant applications, and fan coils. Typical geothermal hydronic systems are limited to water temperatures around 130°F which can make replacing fossil fuel boilers difficult. This system has been designed specifically to meet these higher temperature requirements and makes upgrading to a WaterFurnace system easier.
