Types of Geothermal HVAC Systems

Geothermal HVAC system provides warm and cold air to a building by utilizing the laws of heat transfer. This kind of system’s dual capabilities increases the attraction of geothermal energy to households. A single unit may require less room than both a furnace and a central air conditioner. Three variables will determine which system is the best choice for your house. These include the presence of a water source, the state of the soil, and the amount of rock that surrounds the building.

Installing geothermal loops beneath the surface enables them to capture the heat from the earth and deliver it to the house. The horizontal, vertical, pond/lake, or well water loops are used in the four primary types of geothermal HVAC systems. You can choose the ideal solution for your house with the assistance of an expert.

Horizontal Loop Systems

Horizontal loop systems need additional room. As a result, a bigger lot is required for this choice. A horizontal loop can accommodate continuous liquid flow since it is always closed. For every ton of cooling and heating capacity the home needs, this type of system needs at least 400–600 feet of looping space beneath the ground. Before creating a plan, your HVAC repair professional can do a load value calculation to ascertain your heating and cooling requirements.

Vertical Loop Systems

Vertical loop systems are frequently used in bigger structures, such as commercial buildings and educational institutions. Closed loops are also used in this system. It can be put in place in locations with shallow soil or to lessen the disruption to already-existing landscaping.

Well-Water Loop Systems

One of the more economical solutions for people who have wells on their homes is a well-water loop system. With a single point of entry at one end and a discharge point at the other, this type of system is typically an open loop. To avoid contaminating groundwater, HVAC repair personnel installing open loop systems must adhere to government limitations and rules.

Pond/Lake Loop Systems

Pond/lake loop systems are another affordable choice for landowners who have access to a lake or pond. Since the system is closed, digging is necessary during installation to connect its subsurface and indoor components. Since many homeowners don’t have lakes or ponds on their properties, these are less frequent. However, if you do, it’s the best choice.
