The energy efficiency of heat networks is determined not only by heat losses, but also by the actual service life, since energy is also expended on the production of new pipes and the replacement of worn-out ones. The article describes the main characteristics of the state of the centralized heat supply system, which ensures the quality and safety of heat supply. Based on the analysis of existing models of physical wear of pipelines and equipment of heating networks, as well as the probability of their trouble-free operation, a mathematical model of damage accumulation has been proposed. The model presented in the article makes it possible to qualitatively describe the process of damage accumulation in heat networks as they are used.
