Description/Abstract:	Ground source heat pumps (GSHPs) show promise for reducing house energy consumption, and a desuperheater can potentially further reduce energy consumption where the heat pump from the space conditioning system creates hot water. Two unoccupied houses were instrumented to document the installed operational space conditioning and water heating efficiency of their GSHP systems. This paper discusses instrumentation methods and field operation characteristics of the GSHPs, compares manufacturers' values of the coefficients of performance calculated from field measured data for the two GSHPs, and compares the measured efficiency of the desuperheater system to other domestic hot water systems.
