description: The manuscript considers the main types and structures of district heating systems in St. Petersburg. The features and key aspects of improving the efficiency of heat supply in Primorsky District are analyzed. The average outdoor air temperature and duration of the heating period were analyzed. Heat supply regulation schedules were optimized. A methodology for calculating heat energy overconsumption was developed. Technical and economic analysis and assessment of the feasibility of transition to a closed heat supply system were performed for a neighborhood in the Primorsky district of St. Petersburg. Loads for each subscriber input were determined. Optimal schemes for heat supply points were analyzed and selected. Relative cost reduction for the quarter of Primorskaya boiler house after implementation of energy saving measures was calculated. The amount of investments for the transition from an open heating system to a closed hot water supply system was determined. Calculations have shown that conversion of open heat supply systems to closed systems with automation is not economically viable for any option in St. Petersburg. In order to improve energy efficiency and reduce the populations payment for heating of buildings, it is recommended to introduce optimal schedules of centralized regulation at the sources.
