Geothermal HVAC Systems

How Does Geothermal Heating Work?

Geothermal heat pump systems, also called ground source heat pumps, use the constant temperature of the earth to heat and cool homes and buildings. These systems consist of a network of underground pipes, or loops, that are filled with a mixture of water and antifreeze solution. A ground loop is buried underground and can be installed horizontally or vertically, depending on the available land area and the specific needs of the home.

While in heating mode, the system extracts heat from the earth and transfers it into the building. The fluid in the loops absorbs heat from the earth and circulates it through a heat exchanger inside the heat pump. The heat pump then amplifies the heat and distributes it throughout the building using a duct system or radiant heating.

During the spring and summer months, the process is reversed. The heat pump extracts heat from the air inside the building and transfers it into the fluid in the loops. The heat is then dissipated into the earth, allowing the cooled fluid to be recirculated back into the building.

Benefits of Switching to Geothermal Heating and Cooling

Lower Energy Costs

While the upfront costs of installing geothermal heat pumps are typically higher than other types of HVAC equipment, the long-term savings will make up for it over time. Geothermal heat pumps move heat towards or away from the earth, depending on if it’s set to heating or cooling. This simple operation uses less energy than other types of HVAC equipment, leading to lower heating and cooling costs.

Reduced Carbon Footprint

A geothermal HVAC system uses electricity and geothermal energy from the ground to heat and cool your home. This is a much more sustainable practice than other types of HVAC systems which might use fossil fuels and other non-renewable resources

Improved Property Value

Geothermal systems are growing quickly in popularity due to their overall efficiency and reliability. A home with a geothermal heat pump installed can significantly increase its property value.

Year-Round Comfort

Contrary to other types of HVAC systems, geothermal HVAC units provide both heating and cooling from a single system. This means you only have to maintain a single system, rather than a separate heating and cooling system.

Geothermal Repair and Maintenance

While geothermal HVAC systems are typically very durable and reliable systems, issues can occasionally occur that require professional repairs. Rusk provides homes in the Greater Cincinnati and Northern Kentucky areas with high-quality repair services. If your system isn’t providing even temperatures or energy bills are rising, contact our team today.

Like all other appliances and HVAC systems, geothermal heating and cooling units require maintenance to keep the equipment running at optimal levels. Schedule semi-annual maintenance to help your system run well and prevent issues from developing.
