Pros & Cons
Of Each Technology
The US Department of Energy (DOE) reports: "Geothermal heat pumps are among the most efficient and comfortable heating and cooling technologies available. This technology has been keeping consumers comfortable for more than 50 years."
​There are two types of Geothermal Heat Pumps - Closed and Open Water Loops and Direct Exchange.
​
-
Closed & Open Water Loops - use water/glycol/methanol circulated in buried plastic pipes to transfer heat from the ground.
-
Direct Exchange 'DX' - uses refrigerant circulated in copper tubing as the heat transfer medium.
All use the same physics principle, using the earth as a 'heat source" and 'heat removal".
​Along with two geothermal technologies comes more than one methodology to transfer geothermal energy from the ground into a structure. You can transfer the earths heat by circulating refrigerant in copper pipes ('DX' Direct Exchange) or circulating water through plastic pipes (water loops).
Both geothermal technologies are many times more efficient than conventional oil or gas systems. Consumers save up to 75% on annual heating and cooling bills. i.e. a 4000 sq. ft. home in Westchester, NY is comfortably heated and cooled for about $135. per month - all in! (request the case study).
The Geo Groups vast knowledge of building performance allows us to determine the best geothermal system for your application, structure and location. For most applications, Water Loop Systems is the technology of choice. Both are incredibly efficient. ​ There are many applications where Water Loop Systems better serve the project. The Geo Group will specify and install the system or combination of systems, most suited to the application.
​
Most HVAC and drilling contractors install one or the other. The rationale has more to do with their comfort level with installation rather than the appropriate technology and equipment for a specific application.
​
The Geo Group specializes in all technologies with firsthand experience in both, 'DX' Direct Exchange and Water Loop Systems for new construction and retro-fits for residential and commercial properties.
Pros & Cons
Pros - Water Loop Systems
Cons - Water Loop Systems
-
Water Loops require larger field to accommodate drills and excavation.
-
Higher field disturbance - large diameter holes generate 'tailings'.
​The Geo Group has supported Direct Exchange across various projects; however, it's essential to evaluate several factors to identify the technology that aligns best with your project's needs, comfort level, and goals. Below, we present the advantages and disadvantages of each technology.
​
​
-
The Water Loop System Installation industry generates $8 billion annually.
-
There are 15 leading US brand manufacturers, including Enertech, Water Furnace, Bosch, and Dandelion, to name just a few, who provide competitive pricing on equipment.
-
A Substantial Resource Base includes:
a. Drilling - Water Loop Systems require standard water well drills with a diverse range of trained and experienced crews.
b. Service/Maintenance - With advanced technology comes the need for service and maintenance. Major brands offer reliable warranties, along with knowledgeable technicians and technical support.
c. System Technology - The water loop system features a convenient remote monitoring system and user-friendly thermostats compatible with geothermal systems.​​​​​​​
​​
​​
Pros - 'DX' Direct Exchange
​
-
'DX' requires smaller equipment which can be maneuvered in tighter locations - accommodating many locations and structures.
-
Smaller bore holes require less excavation and field disturbance.
-
Copper-based transfers are more efficient in transferring energy (heat) to and from the ground, resulting in greater energy savings. 'However, there are ongoing debates about the safety of copper and refrigerants in the ground.'
​​​
Cons - 'DX' Direct Exchange
​
-
Only One (1) Manufacturer builds and supports DX heat pumps.
-
DX is a niche market (under 2% market penetration).
-
Few trained and experienced DX technicians - service can be challenging and costly.
-
DX necessitates specialized drills and operators, which are not widely available. Limited drills and qualified operators.
-
Equipment is more costly than water loops - heat pumps and copper infrastructure.​
