This invention relates to methods of operation of heaters for fluid media equipped with means for heat obtaining and intended for extraction of latent heat from exhaust gas through condensation of water vapor present there. Method for contact heating of water is in the fact that the preliminarily heated back water is heated to maximal temperature at bubbling its layer with combustion products from apparatus for immersed burning, those are than directed to the heat exchanger - utilizer for preliminary heating of back water where there are simultaneously the combustion products cooled and the water vapor included in those condensed. At that, the burning air is heated and humidified in evaporation scrubber, due to feeding to it a part of the back water supplied for heating, this is at the same time cooled and than used in heat exchanger - utilizer for the smoke gas deep cooling.
