Taking a Closer Look at Geothermal Heat Pumps

Now that you have become acquainted with how geothermal works in Dexter with the first part of our series, it’s time to take a look at the pump and how it generates the heat for your home or business. This post will cover the inner workings of a geothermal heat pump, and hopefully shed some light on the energy savings that are trapped beneath your feet.

There are two main parts to a geothermal heat pump that work hand in hand to heat and cool your building: the condenser and the evaporator coil. The condenser will extract the existing heat that is stored in the ground, while the evaporator coil will work with the heat inside the home. Thus, the heat pump works by transmitting heat from one unit to another depending on whether you need heating or cooling.

The compressor moves an eco-friendly refrigerant that brings the heat in from outside for heating needs. It functions in reverse when cooling is needed for the warmer summer months. When cooling your home, high temperature, high-pressure gas flows through the buried loop and loses heat. This transforms the refrigerant into a high temperature, high pressure liquid. At this stage, it is allowed to expand, absorbing heat from your home as the fan coil unit blows across the evaporator. With the gas stealing the heat from the air, cooler air is distributed throughout your home. The refrigerant departs the evaporator and moves to the condenser to redo the process.

All of our geothermal heat pumps are designed to maximize your heating and cooling efficiencies. Contact Haley Mechanical today for more info on how we can help you save green on your utilities, and stay tuned for part 3 in our Introduction to Geothermal series: Geothermal Loop Systems.
