For many people, geothermal heating and cooling systems might seem a bit mysterious and even confusing. The main concept is simple though. The temperature of the ground just below the surface remains at around 55 degrees year-round. In the summer, this temperature is low enough to cool a home. In the winter, the temperature is warm enough to heat a home. The confusion arises perhaps in how this temperature is transferred to a home or building to produce heating and cooling. We have broken down the basic facts and benefits behind geothermal heating and cooling to give you a better understanding.
The Basic Facts
The engineering elements of geothermal systems include the heat pump and a series of underground pipes. The way these systems are designed provide many benefits both environmentally and financially. The following are just few of many ways geothermal can help the environment, and your wallet.
- The EPA touts geothermal as a clean, energy-efficient heating and cooling source
- Geothermal heat pumps save money due to their low operating costs
- Geothermal is a renewable resource
- The technology reduces greenhouse gasses by as much as 40 percent over traditional systems
Largely because of these efficiencies, the market for geothermal systems has grown in both residential and commercial clients in recent years. Its growth has been spurred by a number of local, state, and federal tax credits.
The Bright Future
Geothermal heating and cooling systems have been around for many years. With each year comes new and improved changes, including some particularly profound ones in recent years. These changes have been fueled by past experience and new technologies. The biggest advances have been in the efficiencies of high-end motors and compressors. Their control systems have also seen marked improvements in unit controls that analyze data and allow for remote monitoring and other smart systems.
