How Geothermal Drilling Works

The most common method is to drill vertical boreholes from 300ft to 1000ft and drop HPDE loops onto them.  These loops are set in place with a thermal conductive grout and then tied into the buildings heat pump.   Heat pumps move heat from one place to another using electricity.  Air conditioners and refrigerators are examples of heat pumps but use the air around them to dissipate the heat.   Geothermal heat pumps use the earths underground formations to acheive the same result but at a much lower overal energy cost.

Below the ground surface, at depths of 30 ft, the temperatures remains relatively constant year round between about 50°F (10°C) and 60°F (15°C)).  This means the formation temperatures are usually warmer than the air in winter and cooler than the air in summer. 

Geothermal heat pumps take advantage of these constant underground temperatures to efficiently exchange temperatures, heating buildings in the winter and cooling buildings in the summer.


About Geothermal Wells

Paired with solar, wind or any other power source, Geothermal Heat Pumps are the best way to achieve NetZero results.  Geothermal Heat pumps use the earths properties as thermal battery for storage.  The ground serves as heat sink to dump heat in the hot summer months and a heat source in the in the cold winter months.  When the outside ambient temperature are colder than the ground (less than 50-60 °F) then the heat pump pulls heat from the ground and transfers it into the building.   When the outside ambient temperatures are hotter than the ground (above 50-60 °F) then the heat pump pulls the heat from the building and deposits it into the ground.

Choosing a Drilling Company

Choosing the right company is a crucial decision. It is important to ask questions, get information, and know what is expected of you and the driller. Asking the right questions now will prevent problems down the road.

First and foremost, a Driller must have the proper license and insurance. Ask around, and get lots of opinions about the drilling company you are interested in. Compare estimates; if one is cheaper, find out why.

The more you know beforehand, the better you will feel when making your final decision.
