FIELD: power industry.
SUBSTANCE: heat station (HS) of two-pipe water system of centralised heat supply has circulation electric pumps of heating and hot water supply (HWS) systems, which are connected to heating network as per an independent scheme, includes pressure bypass line mounted on return pipeline parallel to outlet main line gate valve by means of two process gate valves or cranes and including rotary machine with high efficiency and rotary machine with low efficiency; at that, rotor of machine with high efficiency is kinematically connected to rotor of circulation electric pump of heating system, and rotor of machine of low efficiency is kinematically connected to rotor of circulation electric pump of HWS system.
EFFECT: reduction of electric power consumption with heat station from external electric network.
