This research was conducted to quantitatively estimate the performance of a GWHP system compared with that of an air source heat pump by the developed system.

A key part of the GWHP design process is the determination of the well pump power required for a range of ground-water production rates.
For GWHP systems, the following are the primary issues in groundwater handling:
The uncorrected power inputs for cooling at WLHP conditions and heating at GWHP are as follows:
