Understanding Geothermal Heating Systems
Geothermal heating systems are becoming a popular alternative to traditional heating systems. They work by utilizing the constant temperature of the earth to heat or cool a home in a more energy-efficient way. In fact, according to the United States Environmental Protection Agency, geothermal heating systems can save homeowners up to 70% on their heating and cooling costs.How Geothermal Heating Systems Work
Geothermal heating systems use a series of pipes buried in the ground to extract the heat from the earth. These pipes are filled with a mixture of water and antifreeze and run through an underground loop system. As the fluid in the pipes move through the underground loop, it absorbs the heat from the earth and carries it back up to the home’s heat pump. The heat pump then transfers the heat from the fluid to the air that circulates through the home’s ductwork. In the summertime, the process works in reverse, using the heat pump to remove heat from the home and transfer it to the earth.Benefits of Geothermal Heating Systems
Geothermal heating systems offer a variety of benefits to homeowners beyond just energy efficiency. Some of these benefits include:- Lower operating costs
- Longer lifespan (20-25 years compared to 15 years for traditional systems)
- Low maintenance
- Quiet operation
- Improved indoor air quality (due to lack of combustion and no need for ductwork)
Do You Need Backup Heat with Geothermal?
In most cases, a backup heating system is not necessary when using a geothermal heating system. These systems are designed to provide ample heating for the space they are installed in and come equipped with electric auxiliary heating units that will activate if an issue arises with the geothermal system. However, it’s important to note that in areas with extremely low temperatures, a backup heating system may be required to supplement the geothermal system during cold snaps.The Role of Auxiliary Heating Units in Geothermal Systems
Auxiliary heating units are installed in geothermal systems to provide a backup source of heat in the event that the primary system fails or needs assistance during extreme weather. These units are typically electric and can be programmed to activate automatically if the temperature in the home falls below a certain threshold. It’s important to note that auxiliary heating units are not designed to replace a primary heating system. They are simply designed to provide a temporary source of heat until the primary system can be repaired or until the weather returns to normal.Using Geothermal Heating as a Sole Heating System
In most cases, geothermal heating systems can be used as a sole heating system without the need for a backup. However, it’s important to ensure that the system is appropriately sized and installed to meet the heating demands of the home. It’s also important to ensure that the home is properly insulated and sealed to prevent energy loss. In some cases, homeowners may opt for a backup heating system for added peace of mind, but it’s not always necessary.Troubleshooting Your Geothermal System for Optimal Heating
If you’re experiencing issues with your geothermal heating system, there are a few things you can try before calling for professional help.- Ensure that the thermostat is set correctly and functioning properly
- Check that the air filters are clean and free of debris
- Check the circuit breaker to make sure the system is receiving power
- Inspect the outdoor unit for any damage or obstructions
