Object of research - processes of heat exchange in tubular gas heaters, which affect the unitary and complex attribute of reliability of heat supply systems. Purpose of research - to ensure the reliability of the heat supply systems with tubular gas heaters. Methods of research - theoretical researches are based on the deductive and inductive approaches with the use of common laws of conservation of mass, movement and energy tasks of calculation of processes of heat and mass exchange for the estimation of workability and control of the regimes of heat supply systems with tubular gas heaters. Chapters of scientific work are focused on the research of unitary attributes of the reliability of heat supply systems with tubular gas heaters, such as the infallibility and control of regimes. The classification of states and development of large systems of energetics is presented in the work. It can be used for the heat supply systems with tubular gas heaters. Criteria of reliability for infallibility and control of regimes were offered. Methods of their calculation were listed. With the help of evolutionary search and T.Saaty matrices the estimation of parameters of the breakdown of tubular gas heaters was made. The use of evolutionary search of the most preferable decisions allows to improve the processing of expert evaluations with the help of this matrix. Quasi two-dimensional mathematical model TGH was constructed on the base of experimental data of temperature allocation along the perimeter of the tubular gas heater, depending on the constructive and regime parameters. Experimental researches were implemented on the real objects - tubular gas heaters, which were installed in the operating heating systems and on the stand during testings. All chapters were driven to its logical end in the form of the practical use of the results in the practice of building design and construction of tubular gas heaters for systems of air-radiant heating and in the educational process of higher educational establishments.
