Urban renovation of the hot water supply system

By Taraday Oleksandr, Gvozdetskiy Oleksandr and Fomich Sergii


Issues related to improving the reliability of hot water supply systems are considered. Currently, centralized hot water supply systems are in an emergency condition due to the fact that the external networks are made of black pipes without anticorrosive coatings. A fundamental difference between hot water supply systems and heating systems is the nature of black metal corrosion. The purpose of this article is to conduct a research of the state of hot water supply systems and consider options for their recovery. The options suggested for restoration of hot water supply systems in cities and settlements of Ukraine are the following: complete replacement of failed networks with new pre-insulated plastic pipelines; refusal from external networks of centralized hot water supply systems and a central heat point with the installation of individual heat points in each house; decentralization of hot water supply systems by installing electric water heaters. A technical and economic comparison of these options is carried out, and the advantages and disadvantages of each option are considered. The arrangement of a set of individual heat points instead of one central point cannot be considered as the recommended method, because of the need for large additional costs for the reconstruction of heating, water supply and electricity supply systems. The most technically and economically justified method from the considered renovation methods of hot water supply systems is the complete replacement of failed steel pipelines with new nonmetallic pre-insulated structures
