FIELD: heating.
SUBSTANCE: invention is aimed at using effluent water heat and can be applied in heating engineering. The method implies using effluent water being purified in the aerotank, resting or moving with the speed close to zero as a heat transfer medium. The remote heat exchanging unit which is placed in the airlift immersed within the effluent water at the total depth of the aerotank is surrounded by a zone of intensive air-water mixture production with the help of, for example, plastic enclosure shields; velocity of the mixture upward flow is regulated by a gate valve mounted at the heat insulated pipe for supplying compressed air to the airlift.
EFFECT: simplicity and efficiency of effluent water heat utilisation.
