What is a Geothermal Heat Pump?

Go Direct  May 31, 2021

Purchasing a new heating or cooling system for your home or business is a big financial decision. Many consumers will research what works best for the environment and the size of the facility. With a Geothermal Heat Pump, your building’s temperature can be controlled in the most energy-efficient form possible. By mitigating the use of fuel used, as well as heavy electricity, savings will be returned, thanks to geothermal efficiency. Follow along as Go Direct Appliance shows why a Geothermal Heat Pump is one of the smartest investments you can make.

How does a geothermal heat pump (GHP) work? By using earth’s constant temperature from below the frost line, the GHP is then able to move that heat from the ground to your facility at your desired temperature. Since there are little fluctuations in temperature below ground, geothermal heat pumps are able to use less energy to heat and cool as opposed to a traditional furnace, which uses frequent temperature changes happening above ground. Geothermal heat pumps are designed as a renewable alternative to a traditional furnace. A typical furnace will create heat by burning oil or gas in a combustion chamber, while a GHP conserves energy by moving heat from the ground that already exists. 


A geothermal heat pump typically consists of two major components. The first component is the actual GHP that sits inside the building, typically where a traditional furnace would be installed. The second component are the sets of ground loops, which are underground pipes that help regulate heat. These loop systems are installed in the yard below the frost line. The two types of geothermal heat pumps supplied by Go Direct Appliance include horizontal pumps and vertical pumps. Horizontal pumps are generally better suited for residential projects, as the loop systems are installed in a shorter trench, which minimizes installation costs. Vertical systems are often used in commercial settings or for schools, minimizing the disturbance of existing landscapes. These geothermal heat pumps can last for 20 to 25 years, and the underground loop systems can last for 50 to 100 years!


Geothermal heat pumps are designed to operate with little maintenance required. To ensure your system runs to the best of its ability, be sure to change out filters every three to six months. Every five years, have a qualified technician inspect your system to ensure that there are no issues with internal components. By having the GHP installed indoors, your equipment will be protected from harmful pollutants and debris outside. Typical furnaces are composed of inner parts that could lead to combustion. Geothermal heat pumps on the other hand, have no combustion chamber, meaning your system will not be prone to damage from flames. GHPs are very efficient, for every one unit of energy used to power a geothermal system, four units of heat are supplied. In short, geothermal heat pumps are practically 400% efficient!
