The research is devoted to solving the urgent problem of increasing the efficiency of decentralized heat supply of public buildings and industrial enterprises with typical municipal and industrial heat generators on the basis of heat pump energy conversion of pre-cooling of heat flows of the return energy carrier from the heat network, initial cold water and flue gases. The aim of this work was to analyze and identify conditions that would increase the energy efficiency of the improved system while expanding the total volume of generated heat for decentralized heat supply. Additionally, the work aimed to ensure the environmental friendliness of primary fuel energy use. The proposed approach aims to improve the energy and environmental performance of heat sources by regulating the temperature of the waste energy carrier to its design value, following a standardized temperature schedule. The most important result of the study of the improved system of decentralized heat supply is the established generalized dependence of determining the actual conversion coefficient in the heat pump operation. It allows qualitative analysis of the dependence of energy efficiency of the heat supply s
