One of the first and most significant factors that you should know about geothermal heating systems is that they not only provide heat during the cold months but also cool your home when it is hot. To switch from heating to cooling, you just flip a switch, so the system keeps the indoors comfortable year around. To get the most from a geothermal system, HVAC contractors can evaluate the needs of your specific home and determine if any supplemental heating or cooling equipment will be needed, whether vents will need to be installed, and additional details that are specific for your home.
How a Geothermal Heating System Works
The sun heats the earth, and the ground below the surface of the earth retains the heat. While we go through cold, hot, and intermediate seasons, the temperature four to six feet below the surface stays constant. A geothermal system is placed underground where it can absorb the heat from the earth and transfer it to the home. When cooling is required, the system pulls hot air out of the home and transfers it to cooler ground beneath the surface.
The geothermal system is made with an indoor unit and an earth loop that is buried outdoors. The indoor unit heats the home by compressing the heat so that it is at a higher temperature before distributing it through the home. When too much heat is inside the home, the system pulls the heat from indoors and carries it to the earth through the earth loop. HVAC contractors will also be able to determine whether an open- or closed-loop system will work best in your home. Many homeowners also appreciate the fact that the heating system is out of sight, unlike heat pumps that are unattractive and exposed to the elements, and which pose a hazard to children playing outdoors.
Qualities Associated with Geothermal Heating Systems
A geothermal system will provide 80% to 100% of your heating and cooling, without the cost associated with burning fossil fuels. This makes it a very cost-efficient method of making your home comfortable. Another difference between geothermal and traditional HVAC units is that the geothermal system is virtually maintenance-free. Although the cost of geothermal is initially higher than other types, it will normally pay for itself quickly and continue to save you money by providing heat without a fuel source.
Importance of Professional Installation
Like any heating system, the efficiency of geothermal heating systems depends on the accuracy of the installation. The buried loop that the system uses to operate lasts for several generations, while the indoor unit is protected from the elements and requires only filter changes and periodic checks. Also, appropriate earth-to-coil contact is necessary for optimal operation. Some locations also have laws and regulations related to the installation of geothermal units. Hiring a professional HVAC contractor will ensure that the installation of your unit is compliant and performed accurately, for the best and long-lasting operation.
The area where the heating system will be installed will determine the best type of system and a number of features that will determine how well the system operates. Professional HVAC contractors have the expertise to determine the best configuration for your new system and provide you with the best installation process. To learn more, call (770) 908-8488.
