The paper examines single-stage layout connection of hot-water supply heaters in residential buildings to closed heat-supply system. The performance of two automatic regulation systems is analyzed: firstly, of the system with a heat-feeding regulator to direct-action hot-water supply and, secondly, of the system of indirect action, with regulation by two-way valve with electric actuator. The modes of heat consumption are studied and relative values of heat consumption of hot-water supply for two buildings are determined. Recommendations for heat consumption decrease have been developed.
