Determination of efficiency and reliability criteria for the actual district heating system and proposals for the development of a distributed heating supply area based on prosumer

The paper presents the main results of practical application of the developed methodology for efficient expansion of district heating systems. The methodology at issue involves determining the efficiency areas of district heating, assessing technically and economically the implementation of distributed heating sources of prosumers at the boundaries of effective heat supply radius; analyzing and ensuring the reliability of heating to consumers in the district-distributed area of the system.
