FIELD: hot-water heating systems.
SUBSTANCE: apartment-by-apartment double-wound heating system has apartment entering unit, feeding and back pipelines connected to the unit, heating devices connected in series with feeding and then to back pipeline, air discharge unit. Apartment entering unit is connected with hydraulic mixing units through feeding and back pipelines. Any hydraulic mixing unit is connected with heating devices through top and lower branch pipes. In any hydraulic mixing unit, which has organ for letting heat-transfer agent through heating device and by-pass, part of heat-transfer agent passing through heating device is mixed with transit part of heat-transfer agent, which flows through by-pass of hydraulic mixing unit. Gas discharge unit is mounted at top part of heating devices at the opposite side of hydraulic mixing unit. Heat flow of heating device is controlled while hydraulic and thermal stability of heating system is kept to a certain limit. The system allows using radiator-type-heating devices.
EFFECT: ability of controlling heat flow of heating device; safe of heat energy.
