The paper analyzes the connection diagrams and operation of buildings heat supply systems, taking into account the impact of changing weather and climate influences during the heating season. High-quality central heat consumption control was carried out, at which the heating carrier flow rate was maintained at a constant level, and its temperature varied according to a predetermined schedule. Thermal characteristics or mode of operation of the building differed from the data set in the schedule, as a result, more heat was consumed in certain periods. Its overrun was also observed during the warm period of the heating season, when, due to the maintenance of the hot water temperature at the right level on the outlet from the water-heaters, the heating carrier from the source was supplied with a temperature exceeding the established norms. The results of field tests and the diagrams of heat supply for heating at the heat supply operation in central heating points are presented. The main accent is made on the study of multi-circuit heating systems with frontal control of heat supply.
