Geothermal Energy FAQs

The earth absorbs approximately 47% of transmitted solar energy and stores this free thermal energy beneath our feet. 

Even though the air temperature is hot in the summer and cold in the winter, the ground temperature just a few feet below the surface is relatively constant year round.

Geothermal energy systems take advantage of this by transferring the warmer energy into our homes in the winter. In the summer, the process is reversed. The earth is like a large solar collector and storage battery, with more than enough thermal energy for everyone.

A geothermal energy system utilizes the large amount of energy/heat stored in the earth beneath our feet. Since geothermal energy systems only move heat, and do not need to create this energy by burning fuels or standard electrical consumption, efficiencies as high as 500% can be expected in this area. The small amount of electricity needed to operate the heat pump compressor and ground loop circulators can transfer 4 to 5 times that amount in thermal energy for the home.

Absolutely! The EPA has called geothermal systems “the most environmentally friendly way to condition our homes.” A ground source heat pump does not have an exhaust and emits zero carbon dioxide. Removing the combustion process from heating reduces our dependency on foreign oil and eliminates the potential for carbon monoxide poisoning. Geotherm only uses heat pumps with R-410a – ozone safe refrigerant and clean geothermal antifreeze with deionized water.

Three basic components make up a geothermal energy system:

  1. The Ground Loop Heat Exchanger
  2. The Ground Source Heat Pump
  3. The Distribution System (ductwork, radiant flooring, fan coil, etc.)

That really depends on your situation. There are four basic geothermal system loop types:

  1. Horizontal Closed Loop
  2. Open Loop
  3. Vertical Closed Loop
  4. Pond/Lake Loops
