Geothermal / Renewable Energy Technology


Geothermal systems are electrically powered systems that tap the stored energy of the greatest solar collector in existence: the earth. These systems use the earth's relatively constant temperature to provide heating, cooling, and hot water for homes and commercial buildings. The Department of Energy (DOE) and the Environmental Protection Agency (EPA) have both endorsed ground source heat pump systems as among the most energy efficient and environmentally friendly heating, cooling, and water heating systems available.
- Closed Loop Geothermal Systems
The ground source heat pump (GSHP) in the building pumps fluid through horizontal and vertical exterior piping, gaining energy from the earth before re-entering the building.

Residential InstallationAllied is the most experienced and knowledgable geothermal contractor in the area. We install more than 1400 loops a year at hundreds of homes.
Tax Credits / RebatesMaryland and its individual counties now offer tax credits and/or rebates for the installation of geothermal systems. For more information, click the links below.
