Replacing thermotechnical systems with fossil fuels is an important area of research in order to use renewable energy sources to create better environmental and economic conditions. To assess the possibility of using high temperature heat pumps in the industry, it is necessary to look at available amount of useful waste heat energy from industrial processes. Thus, in the introduction to this paper, the values of energy consumption within the industrial sector and the currently active limitations defined by the European protocols are mentioned. After describing the basic parameters of the process with heat pump, refrigerants are processed which due to their properties show the possibility of use at high temperatures required for industrial processes such as pasteurization, drying, distillation, etc. Using such working substances opens the possibility of applying a new method. obtaining thermal energy. Industries with large amounts of waste heat can be of great importance from the development of high temperature heat pumps that replace conventional systems to meet thermal needs. This means that the operating costs of current systems can potentially be reduced while also reducing the negative impact on the environment. Despite the still insufficient development and application of industrial heat pumps, there are such commercially available devices and some of them are applied in real industrial plants. Examples from practice and available devices on the market are described within the fourth chapter. Finally, an analysis of the cost-effectiveness of installing a high temperature heat pump of a specific industrial process was performed, which showed that the temperatures of the heat source and heat sink are very important for the selection of the refrigerant which define the evaporation and condensation temperatures. When supplying waste heat at higher temperatures, there are greater possibilities for the choice of refrigerant, and in the end better process parameters are achieved.
