Annotation: The paper has characterized the plants for central heating supply of the cities with the independent joining of the users’ systems of heating and hot-water supply. The advantages of the independent connecting of the local systems to the heating supply networks providing reliability and quality of heating supply protecting users’ leads-in from destruction at emergency have been determined. Water losses are established to be decreased in local heating and hot-water supply systems and protect them from defrosting at pipework pumps shut-down. The joining up of high-rise buildings to the heating supply networks because of the filling up of the system and providing with static pressure on the upper floors enables only in the independent systems. A number of advantages of the independent systems has been determined even in heat supply open systems where the water to the hot-water supply is not contaminated in a heating system that promotes its quality and colourfulness. The application of heating and storage plants with three-contour heat exchangers at the individual points has been determined to solve the problem of independent joining of users’ systems of heating and hot-water supply systems and provide a hydraulic mode in buildings of various number of storeys. The design technique enables to optimize heating and storage plants and increase the heat mass exchanging efficacy.
