Objectives . The study was aimed at improving the reliability of heat supply systems. At present, this is one of the most relevant topics in the field of heat supply. The issue of reliability of heat supply is of great importance in terms of the safety of citizens and the state as a whole. Due to the severity of winter conditions and risk of hypothermia, heat supply security can be considered to be as critical as food security. Therefore, the reliability of heat supply systems becomes one of the most important aspects of the security of the state. Method . The study was carried out using the method of reservation of the heat supply system by looping. Result . In order to avoid the defrosting of the heat supply system and reduce additional costs, a redundancy scheme was proposed with one-way connection to the looped main pipelines, additionally looping the pipelines of the heat supply systems between two boiler rooms. The calculation of losses in the event of an emergency in the heating system was carried out. Conclusion . The most important problem requiring immediate solution is how to increase the reliability and redundancy of the heat supply system itself, in order to achieve minimal discomfort for consumers of heat energy at the time of failure of the source or transmission of the heat supply system. The proposed method for increasing the reliability of operation of heat supply systems is characterized by a high efficiency, since allows the number of idle hours and the total amount of short-received heat to be reduced.
