description: In this work, thermohydraulic as well as durability calculations of a regenerative high-pressure heater were performed. The heater was developed on the basis of PV standard sizes existing in the LDPE nomenclature 900-380-18M. The device should be designed in a vertical design. The thermohydraulic calculation showed that the developed heater has hydrodynamic stability and provides the necessary heating of feed water. The steam velocities in the inter-tube space, as well as the water velocity in collectors and spiral tubes, are within acceptable limits, which prevents erosive wear of pipeline elements, as well as reduces hydraulic pressure losses. As a result of the strength calculation, the reliability of the main unit was proved under working loads and the size of the flange connection parts was selected.
