Header Manifolds for Geothermal System

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the summer can also be used to provide a free source of hot water.”

Ground Heat Exchange Systems

Closed-loop Systems
Closed-loop systems generally consist of a buried piping system constructed from high density polyethylene (HDPE) pipe and fittings. This piping system is filled with a water or water-antifreeze solution and is buried in the ground, usually in horizontal trenches or vertical wells. This ground loop acts as the primary heat exchange device for the home. The fluid is circulated through pipes where it either absorbs heat from the ground (heating mode) or rejects heat to the ground (cooling mode) before returning to the GSHP unit.

Open-Loop Systems
Open-loop systems extract water directly out of a water well or pond and run it through the water-refrigerant heat exchanger in the GSHP unit. After the transfer of heat between the extracted water and heat pump takes place, the water is then expelled back into a well, into a pond, or into a drainage ditch depending on local codes.  

There are factors to be considered when selecting the proper ground heat exchange system for your needs, both effective and efficient, and Gap Mountain Drilling will discuss those with you during your consult.
