The ground source heat pump (GSHP) uses pipes which are buried in the ground to extract heat from the ground. This heat can be used to heat radiators, under-floor or warm air heating systems and hot water in an office room. The GSHP were adopted a closed loop and vertical borehole system. This paper describes an experimental result regarding an amount of transported heat and a coefficient of performance of the GSHP. The GSHP system will operate continuously during a month or more. The measuring accuracy of the amount of heat transported by the GSHP were evaluated and discussed.
