In Texas, geothermal energy provides a reliable and economical source of comfort for almost year-round home cooling requirements. A geothermal energy system provides exceptional cooling at a monthly cost that is usually much lower than other forms of cooling. The overall benefits of geothermal energy make it an attractive option for Dallas area home and business owners.
Basics of geothermal energy
Geothermal cooling and heating systems are based on heat pump technology. Instead of generating heating or cooling, the heat pump system captures heat and moves it in or out of your home. In a ground-source system, this is accomplished in a series of pipes buried in the ground at a depth where the temperature stays about 50-55 degrees all year long. Water-source systems are based on a similar concept, but the pipes are placed in a lake, pond, aquifer, or other body of water at a depth where the temperatures stay consistent.
A water/antifreeze solution (or in some cases refrigerant) flowing through the pipes is the medium of heat transfer. This solution either captures heat from inside your home and disperses it into the ground or water, which cools your home, or captures heat from the ground or water source and brings it into your home, where heat pump technology converts it into heating.
Installing a geothermal energy system requires careful consideration of the area where the underground or underwater pipes will be installed. For example, there must be enough ground space for the trenching and digging required to place the pipes. A horizontal system requires a wide flat area, while a vertical system requires deep holes for installing the heat transfer pipes.
Geothermal energy benefits
As a source of home cooling, a geothermal energy system provides multiple benefits that make it a good choice.
- Very high efficiency: Geothermal heat pumps are extremely efficient, which means they provide indoor cooling at a lower price than other systems. Savings of 25 to 50 percent on monthly cooling bills are common. A geothermal system can often pay for itself in savings alone by about the halfway point of its expected lifespan. Plus, there’s a 30 percent tax credit for qualifying geothermal systems.
- Quiet operation: Geothermal cooling systems run very quietly compared to traditional heating and cooling systems.
- Environmentally clean: Geothermal energy systems do not burn fuel, so they don’t produce exhaust fumes or additional greenhouse gases. Their efficiency means they use less electricity than other systems, which reduces demand from local electricity suppliers.
