FIELD: liquid handling facilities. SUBSTANCE: invention is designed for heating transferred liquid media. Proposed method of operation includes heating of liquid medium is water heating device, delivering heated liquid medium into heat consuming device and delivery of cooled liquid medium from heat consuming device for heating into water heating device, thus forming liquid medium circulating circuit. Cooled liquid medium is delivered into water heating device through restricting device. Plant contains water heating device connected from side of heated liquid medium flow outlet to heat consuming device and the latter is connected by cooled liquid medium outlet to water heating device to form liquid medium circulating circuit. Water heating device is provided with restricting device from side of inlet of cooled liquid medium from heat consuming device. EFFECT: improved reliability and safety of plant in operation. 8 cl, 1 dwg
