FIELD: geothermal water energy utilization for heat supply to miscellaneous users. SUBSTANCE: method includes transmission of geothermal water heat energy through intermediate heat-transfer apparatuses to secondary heat-carrying agent using chemical energy of dissolved gases as additional energy source with aid of primary and secondary separators; used as additional energy source is associated potential energy of geothermal water and as potential-energy users, expander and compressor mounted on common shaft; gas-holder and gas- distribution center are used for utilizing energy of dissolved gases. EFFECT: enhanced thermal efficiency of energy utilization without using additional energy sources. 1 dwg
