Liquid-to-Air Nordic Heat Pumps

The Nordic® Liquid-to-air heat pumps is a water to air heat pump that harvests their heat from deep below the ground, and distributes it throughout the house in the form of hot air. In the summer, these heat pumps reverse the process and cool your home.

Nordic® R Series Water to Air Heat Pumps

Nordic®’s liquid-to-air heat pump is called the R Series. The R Series is a full package active heating and cooling unit. The R Series works with either well water or geothermal ground loops. This water to air heat pump comes with optional domestic hot water and provides hot water in both the heating and cooling modes. The R Series is available in slim horizontal, vertical, and split configurations.

This type of heat pump is commonly used in residential renovation projects when retrofitting from other air duct systems. The R Series is available in all configurations in sizes from 0.75 to 6.5 nominal tons.
