Based on the average standardized energy cost over the entire lifetime of the project, the possibility of choosing a heat pump installation using low-potential heat as a source of heat for an individual consumer is shown. As an example, to assess the economic performance of a heat pump installation in the Chelyabinsk region 6 variants of heat supply systems are considered, taking into account the climatic characteristics of the region for four types of individual houses. The results of the study showed that the most expensive in the Chelyabinsk Region is 100% heat supply because of a heat pump installation. In terms of the average standardized energy cost, the most attractive is the project with 50% heat supply from the heat pump installation. Comparative analysis of the results of the study with the data of the international assessment of the heating systems and costs of EU energy shows the similarity of the nature of the changes in the given indicators.
