FIELD: heating systems and hot water supply systems. SUBSTANCE: flow of liquid is treated with acoustic field in range of frequency of pulsation of flow of 3.8 to 4.8 kHz for amplifying cavitation mode of operation of rotary pulsation apparatus at resonance frequency of pulsation of liquid flow through active members of rotary pulsation apparatus. EFFECT: enhanced efficiency. 2 dwge
