Understanding the Basics of Thermal Energy Transfer in Geothermal Heat Pumps

How do geothermal heat pumps transfer thermal energy?

Geothermal heat pumps utilize a closed-loop system to transfer thermal energy from the ground to heat or cool a building. The installation process involves drilling boreholes and inserting pipes filled with a heat transfer fluid into the ground. This fluid absorbs heat from the earth and carries it to the heat pump unit.
