FIELD: treatment of water used in the hot-water supply systems. SUBSTANCE: invention relates to the sphere of water treatment with the purpose to remove from it aggressive gases - oxygen and carbon dioxide and may be used in the hot-water supply systems. The method is realized by feeding of the heated water under pressure to deaeration at the temperature of 55-60°C . The deaeration in a separator is conducted in a pressure mode under pressure of 4-6 kg/cm2 and at maintenance of temperature of the initial water. EFFECT: simplification and price reduction the method realization.
