FIELD: heating.
SUBSTANCE: method of cleaning heat exchanger from carbonate deposits is provided, comprising feeding of geothermal water with a concentration of carbon dioxide above the equilibrium value, which is generated by increasing the total, respectively, and the partial pressure of carbon dioxide in the cleaned heat exchanger. The cleaned heat exchanger is connected in series to the clean the heat exchanger, and from the geothermal water before feeding to the clean heat exchanger a part of carbon dioxide is removed to the equilibrium value and fed into the geothermal water before feeding to the cleaned heat exchanger, the partial pressure of carbon dioxide in the cleaned heat exchanger is maintained at a level above the equilibrium value.
EFFECT: invention enables to improve the efficiency of cleaning the heat exchanger and to avoid heat loss of geothermal water used for hot water supply.
