Geothermal energy:

an inspiring energy

What are the pros and cons of geothermal energy?

Types of underground loops:

Horizontal loop

Trenches are dug to a depth of 5 to 6 feet, measuring 300 to 500 feet in length.

  • There are several options for pipe configurations, depending on the available space.
  • A minimum 0.5 acres is required for a typical residential home.

Vertical loop

  • These are drilled down to depths of 50 m to 150 m and more.
  • They are appropriate for new constructions and additions to existing residences with small lots.
  • These do not require much space.
  • Their installation does require specialized equipment and personnel.
  • The cost of installation is higher.

Where does geothermal energy come from?

The sun’s energy heats the ground.

The loop absorbs the heat from the soil and carries it to the building.

The geomatics unit transfers the heat to the house.

Exciting project

The Hellisheidi power plant ranks sixth among the world’s biggest geothermal power plants by installed capacity.

 Interesting facts

Heat is captured in the ground

The heat captured in the ground can reach upwards of 300 degrees Celsius. That happens at depths of over 1,500 metres, and this type of installation is normally found in volcanic zones.


Residential drilling

For residences, drilling goes no deeper than 100 metres, and the captured heat can reach 30 degrees Celsius.
