District heating systems play a vital role in providing thermal energy to residential, commercial, and industrial consumers, particularly in regions with centralized heat supply infrastructure. However, a significant portion of thermal energy is lost during production, transmission, and distribution due to outdated equipment, insufficient insulation, and inefficient operational control. Improving energy efficiency in district heating networks has therefore become a key engineering and environmental priority. This study investigates modern approaches for enhancing the energy performance of district heating systems, including hydraulic optimization of pipelines, application of advanced thermal insulation materials, integration of renewable and waste heat sources, and implementation of intelligent monitoring and control technologies. Analytical evaluation of heat losses, temperature regimes, and energy consumption patterns was conducted to determine the most effective efficiency improvement strategies. The results indicate that comprehensive modernization—combining pipeline insulation improvement, variable flow regulation, and digital control systems—can reduce heat losses and fuel consumption by approximately 20–40% while maintaining stable thermal supply. In addition to economic benefits, these measures contribute to reduced greenhouse gas emissions and improved sustainability of urban energy infrastructure.
The findings of this research provide a practical and theoretical basis for the modernization and energy-efficient management of district heating systems in developing and transitioning energy markets.
