How Does a Geothermal Heating & Cooling System Work?
Geothermal heating and cooling systems draw heat from the groundwater and transform it into heat for your home. Likewise, these modern systems can cool your home by extracting hot air from your home in the summer and transferring it to the ground outside.
What Type of Geothermal Heat Pump Systems Exist?
Horizontal Ground Loop System
This type of geothermal system design is cost-effective on smaller projects or where there is sufficient space for the loop to be installed. Trenches, three to six feet deep, are created and a series of parallel plastic pipes are laid inside them. These loops are folded and connected to the heat pump where the fluid is then circulated, absorbing or rejecting heat from the earth depending on the mode of operation. A typical horizontal loop will be 400 to 600 feet long but will vary according to the soil type and the layout of the piping. Usually, these alterations are in place due to space restrictions.
Vertical Ground Loop System
This type is used mainly in commercial buildings where the need for heating and cooling is strong but the space restrictions are high. Vertical holes 100 to 400 feet deep are drilled in the ground and a single loop of pipe with a U-tube at the bottom is installed. The borehole is then sealed with grout to ensure good contact with the soil. The vertical ground loops are connected to a horizontal underground header pipe that carries fluid to the unit. The earth’s temperature is more stable farther below the surface, which is an advantage for the system's rapid cooling and heating needs. Vertical ground loop fields may be located under buildings or parking lots, making them extremely convenient for large establishments. The life expectancy is in excess of 50 years, proving reliability and ease of functionality.

Benefits of Geothermal Heat Pump Systems
There are many advantages to installing a geothermal heat pump on your property. These benefits include:
- Less costly to operate than traditional HVAC systems: Studies show that geothermal heat pumps can save homeowners as much as 80% on their heating and cooling costs.
- Better overall comfort indoors: Since geothermal heat pumps deliver precise amounts of air, this eliminates hot and cold spots inside your home. Ordinary gas furnaces may provide blasts of warm air, but geothermal systems provide consistent temperatures throughout the rooms on your property.
- Quiet operation: Traditional air conditioners and furnaces as well as air-source heat pumps can be noisy, but geothermal systems are designed to operate quietly.
- Reliable: These modern systems are installed indoors and pipes go underneath the ground outside so they require little maintenance. They are also not subject to wear and tear from rain, snow, ice, and extreme temperatures as are units that are located outside of the house.
