The paper presents a proposal of economic aspects application in the process of optimizing the construction of heat recovery unit. The proposed model includes the cost of heat exchanger installation and the predicted economic benefits during the operation of the device. The predicted benefits include an increase of energy efficiency resulting from the number of modules of heat recovery unit, decrease unit efficiency during operation, the cost of heat production, average temperatures in the geographical location and working time. A case study was carried out on the example of a spray booth.
