Ground Source Heat Pumps (GSHP) uses have been increasing in recent years. In areas where the technologies of heat pumps has been applied, because of their reliability, high level of comfort, low demand, and low operating costs, they are one of the best system for application. Initially these systems were most popular in rural, residential applications where heating requirements were the primary consideration. However, recent improvements in heat pumps units and installation procedures have expanded the market to urban and commercial applications.

One of general forms of ground source heat pump (GSHP) system application is space heating and cooling. Building cooling may be provided by circulating water directly between the ground loop heat exchanger and chilled ceilings or beams. In this system, the heat extracted from the ground for heating is replaced during the cooling season.
