Ground-source heat pumps use the thermal energy of the ground or groundwater to provide a heating or cooling source for a home. There are three basic types: closed loop, open loop and direct expansion.
The cooling function is measured by an energy efficiency ratio (EER), and the heating function is measured by a coefficient of performance (COP). The higher the EER or COP number, the more efficient the heat pump is.
Which Heat Pump is best for me?
Selecting a geothermal heat pump is not something you have to do on your own. Give us a call we'll go through your individual application and determine the best heat pump for you! Some of the questions we will answer together include:The Earth Connection: Water well, water based ground loops or a waterless direct expansion system installation?
Heat Distribution: Air Duct System, Infloor heating or BOTH?
Sizing your geothermal heat pump: Maritime Geothermal has a very helpful Selection Guide for homeowners and contractors alike to decide the size of unit that fits!

DXTF: Eliminating what comes between your geothermal heat pump and the ground
DX Series heat pump is unique in the geothermal industry, as it eliminates the plastic pipe secondary heat exchanger normally found in conventional systems. Heat exchange is carried out by introducing liquid refrigerant via copper tubing buried directly in the earth. | DXTF Product Ratings EER: 17.6 - 21.0 COP: 3.7 - 4.1 |
Energy Star® Requirements EER: 16.0 COP: 3.6 |
TF Series: NORDIC®'s solution for today's integrated heating and cooling
Triple Function heat pumps are the solution for a home that requires in-floor heating in part or all of the structure while also requiring ducted heating and cooling throughout the building. ECM fan motors are standard, for increased efficiency and comfort.TF Series Product Ratings
Closed Loop: EER = 18.2 - 21.7 COP = 3.8 - 4.2
Open Loop: EER = 22.2 - 25.9 COP = 4.4 - 4.8
Energy Star® Requirements
Closed Loop: EER = 17.1 COP = 3.6
Open Loop: EER = 21.1 COP = 4.1
W Commercial: NORDIC®'s strength and reliability for big loads
Liquid to water - for use on open water wells and closed ground loops - hot water output up to 120°F (49°C) - for in-floor heating, pool heating or any other hot water requirement.W Commercial Product Ratings
Closed Loop: EER = 17.3- 19.2 COP = 3.2 - 3.4
Open Loop: EER = 21.0 - 23.8 COP = 3.9 - 4.1
Energy Star® Requirements
Not Available on Commercial Units.
EMW Series: Efficiency that saves you time and money
The EMW is NORDIC’s all in one solution for in-floor heating systems. The EMW is essentially a premium water-to-water heat pump with buffer tank, backup heat, indoor circulators, and control electronics in a single unit, utilizing the Copeland Ultratech 2-stage compressor for industry-leading efficiency.EMW Product Ratings
Closed Loop: EER = 16.7 - 18.4 COP = 3.2 - 3.3
Open Loop: EER =20.7 - 23.0 COP = 3.8 - 4.0
Energy Star® Requirements
Closed Loop: EER = 15.1 COP = 3.0
Open Loop: EER = 19.1 COP = 3.4
