Geothermal Solutions

GroundHog TechnologyYes it’s finally here. The heat pump that addresses all your fears about ground source and air source heat pumps. The GroundhogTM is our new geothermal heat pump combines air source and ground technology to produce a superior geothermal/air source combination heat pump system. 

Atlas Offers Affordable Direct Exchange (DX) Geothermal Solutions

No matter where you live, the underground temperature remains relatively constant all year, even though outdoor temperatures may vary widely. Geothermal systems utilize this stable resource as a renewable energy source for your home.

Geothermal Heat Pumps = Lower Energy Bill

Air Source / Ground Source Heat Pump

A direct exchange (DX) geothermal heat pump system is a geothermal heat pump system in which the refrigerant circulates through copper tubing placed in the ground. The refrigerant exchanges heat directly with the soil through the walls of the copper tubing. This eliminates the plastic water pipe and water pump to circulate water found in a water-source geothermal heat pump. This simplicity allows the system to reach high efficiencies while using a relatively shorter and smaller set of buried tubing, reducing installation cost. DX systems, like water-source systems, can also be used to heat water in the house for use in radiant heating applications and for domestic hot water, as well as for cooling applications.

Drilling for the geothermal systemBecause of their small earth loop size, DX systems can be installed in relatively small areas and in relatively shallow soil. This provides a flexibility of installation that is useful in allowing many properties to be served by geothermal that could not be served otherwise. A direct exchange system ground loop can be drilled with a small drill rig that can fit into small side yards and gardens under existing trees. It can be drilled in areas where rock is found 50 foot (15 m) to 100 foot (30 m) below ground without the need for actually drilling into rock.

What are the advantages of an air source/ground source geothermal heat pump system?

  • Greater efficiency. Air source heat pumps are often more efficient in less extreme weather. The endless supply of free flowing outdoor air can provide a great source of convection for longer run times without the thermal depletion of the earth field that can occur with geothermal units. Ground source systems are often more efficient in extreme weather conditions. The constant and more stable ground temperatures can provide an efficient source of convection as long as the earth field is not over worked. The ability to utilize both sources gives the Groundhog a unique advantage to achieve comfort and efficiency.
  • Lower installation cost = Lower geothermal heat pump cost. The Groundhog’s multisource technology requires less drilling to obtain the same BTUH as conventional geothermal systems.
  • Faster installation time. Less drilling is less time consuming, and better still, the Groundhog can function without being attached to the earth field which is ideal when a nonfunctioning system needs to be replaced quickly. The earth field can be installed at a later date, and the homeowner can start enjoying the comfort as quickly as with a typical air source system installation.
  • Less threat of a total system failure. In the rare event of a ground loop failure, the Groundhog can still produce adequate heating and cooling.
  • More efficient dehumidification. The Groundhog system uses a multi-speed compressor, as well as a variable speed fan motor to remove more unwanted humidity in the cooling mode.
  • Better balanced heat control. The Groundhog air handler is equipped with MaximizerTM technology which measures the temperature rise at the indoor coil. This allows the system to determine the correct compressor and heat stage mode for the best balance of comfort and efficiency.
