The working project envisages a major overhaul of the heating system of the building of the preschool educational institution "Sonechko", which is located at:   st. Myru, 11, Zmienkove village (former village of Gvardiyske), Odessa district, Odessa region. The project provides for: - replacement of heating system pipelines and heating devices in part of the premises of the ZDO; - connection to the existing heating pipelines that pass through the basement of the building. The overhaul of the ZDO heating system is planned in one turn with the allocation of two start-up complexes, which are located: - 1st start-up complex - premises of the 2nd and partially 1st (in axes 4-9/ A-G) floors of the eastern wing of the building; - 2nd start-up complex - the remaining premises of the 1st floor of the eastern wing of the building, part of the premises of the 1st-story administration block and gallery in axes 4-5/K-L.       The project of overhaul of the heating system provides for a comprehensive modernization of the existing heating system taking into account modern building codes, energy-efficient technologies and safety requirements. The features of the project are the phased implementation of work without stopping the educational process, the use of modern equipment with an increased efficiency and long service life. The implementation of the project is of important social and economic importance, as it is aimed at creating comfortable and safe conditions for students and employees of the educational institution. The project contributes to reducing energy consumption, optimizing heating costs, increasing the reliability of engineering networks and reducing the negative impact on the environment. The need to implement the project is due to the physical and moral wear and tear of the existing heating system, frequent emergency situations, uneven heat distribution in the premises, and high operating costs. An additional factor is the need to ensure a stable temperature regime in accordance with sanitary and hygienic standards.       As a result of the work, the following will be achieved:-ensuring stable and uniform heat supply to all  premises of the educational institution;-increasing the energy efficiency of the heating system and reducing energy costs;-improving the conditions of stay of pupils and work;-reducing the risk of emergency situations and costs for current repairs;-extending the service life of the institution's engineering networks
