Geothermal Technology      
  Mid-Atlantic Geothermal has always maintained a very distinguished reputation for their alternative energy efficient services.

Geothermal energy uses the earth’s ground moderate temperature for heating in the winter or a cooling in the summer. This heating and cooling is used to reduce the operational costs of heating and cooling systems, and may also be combined with solar to form a geo-solar system with even greater efficiency.

Geothermal systems harvest the renewable free energy absorbed near the Earth's surface from solar energy. They utilize the mild ground temperature to transfer excess heat from your home to the earth in the cooling mode, or transfer heat from the earth to your home in the heating mode.

The temperature in the ground below 20 ft is approximately equal to a constant 50 degrees Fahrenheit. A geothermal unit is very similar in size to a traditional furnace or air handler that you probably already have installed in your home and there is no outdoor unit. A typical Geothermal Heat Pump system is so quiet inside a house; homeowners do not even know it is operating!

In addition by using a hot water generator, the geothermal process can use the waste heat to generate hot water in the summer and deliver substantial hot water savings in the winter.

Typical Geothermal Designs:
 


 
 
   
Geothermal Vertical Loop

A vertical closed loop field is composed of pipes that run vertically in the ground. A hole is bored in the ground, typically 50 to 400 feet deep. Pipe pairs in the hole are joined with a U-shaped cross connector at the bottom of the hole. The borehole is commonly filled with a bentonite grout surrounding the pipe to provide a thermal connection to the surrounding soil or rock to improve the heat transfer. Thermally enhanced grouts are available to improve this heat transfer.
  
   
   
   
Geothermal Horizontal Loop

A horizontal closed loop field is composed of pipes that run horizontally in the ground. A long horizontal trench, deeper than the frost line, is dug and U-shaped or slinky coils are placed horizontally inside the same trench. Excavation for shallow horizontal loop fields is about half the cost of vertical drilling, so this is the most common layout used wherever there is adequate land available.
  
   
   
Geothermal Pond/Lake Loop

A closed pond loop is not common because it depends on proximity to a body of water, where an open loop system is usually preferable. A pond loop may be advantageous where poor water quality precludes an open loop, or where the system heat load is small. A pond loop consists of coils of pipe similar to a slinky loop attached to a frame and located at the bottom of an appropriately sized pond or water source.
  
   
   
Geothermal Open Loop

In an open loop system, the secondary loop pumps natural water from a well or body of water into a heat exchanger inside the heat pump. Heat is either extracted or added by the primary refrigerant loop, and the water is returned to a separate injection well, irrigation trench, tile field or body of water. The supply and return lines must be placed far enough apart to ensure thermal recharge of the source.
