The paper evaluates the influence of the scale formation on the inner surface of the heat exchanger on its technical characteristics. The subject of research is a heater 12 OST 34-588-68 Number 12 diameter of 219 of the second stage of hot water supply, intended for heating cold water into a hot water supply system. A survey of the Central heating point and connected heat and water supply systems located in the city of Moscow was conducted. For the study, an analysis of indicators of water quality at a heat point was carried out. In the course of the work, the following were calculated: the intensity of scale formation, their thickness, and also the deviation of the calculated value of the formed deposits from the actual one obtained by field measurements was found. As a result of the work, an increase in the hydraulic resistance inside the tubes of the heat exchanger was calculated in connection with the formation of deposits and an increase in the consumed electricity to ensure the required parameters of the hot water supply system.
