Your interest in geothermal (ground source) heating and cooling systems indicates that you are among a growing number of residential and commercial users who recognize the cost savings and environmental benefits of this superb renewable energy source.

Earth River Geothermal, Inc. is located in Annapolis, Maryland. This area is fortunate to be located in a region that is well suited to geothermal applications. The ground temperature at depth is a constant 57 degrees, which is ideal for both heating and cooling.

Seventy-five percent of the energy produced by geothermal systems comes from the ground under your property. Energy use is typically half the amount used by conventional HVAC systems with similar reductions in green house gas emissions. Geothermal systems provide excellent comfort, a long service life, and pay for themselves through reduced utility bills, normally within five to fifteen years, depending on the type of HVAC system they replace.
