geothermal systemsYou may have heard of geothermal heating and you may have considered a geothermal heat pump for your home. But you still have a lot of questions. What makes geothermal heating and cooling so energy efficient, and how does it work? What about the cost?

Keep reading to learn more about geothermal systems and find out what your options are to make your Annapolis, Maryland, home more energy efficient.

Geothermal Heating and Cooling?

Geothermal heat pumps may sound fairly new, but in fact, they have been around since the 1940s. The use of geothermal heat dates back even further than that because cavemen were able to take advantage of the natural thermal energy found in the earth in several ways.

How is this process possible? The ground temperature stays constant regardless of the season, about 50 degrees Fahrenheit. Geothermal heat pumps tap into that energy below the ground and use it to provide air conditioning for your home. Liquid-filled pipes are buried a few feet in the ground and heat is transferred via this liquid, sending heat to or removing it from your home. Because the temperature in the ground is always cooler than the summer air or warmer than the winter air, much less energy is used to cool and heat your home.

While the setup and installation costs are higher than with a traditional HVAC unit, the system pays for itself within a few years, in part, through lower energy bills. You may even qualify for a tax credit when you have one installed.

Geothermal Heat Pumps

Geothermal heat pumps, on the other hand, draw energy from the surrounding air to heat or cool your home. We offer several energy efficient geothermal heat pumps. The Performance™Geothermal Heat Pump GT offers a two-stage compression and variable-speed blower, and can be more efficient than a furnace/air conditioner combo. The Performance™ Geothermal Heat Pump keeps you warm in winter and cool in summer and includes an optional upgrade for heating your water. If you want to keep your existing furnace, you can choose the Performance Split System Indoor Geothermal Heat Pump.
