摘要

The invention relates to an arrangement, method and system for simultaneously using geothermal heat and obtaining water for use. Said arrangement (100) is installed in a well bore (3) and comprises a heat exchanger arrangement (12) through which a coolant flows and which forms the evaporator of a pump and is located in an upper part (1) of the well bore (3) that is filled out with cement. The invention also comprises a pipeline arrangement which communicates with a water reservoir (5) and which extends through the filled upper section (1) of the well bore (3), into a lower, unfilled water chamber (2) of said well bore (3).
