Technical-economic justification of the choice of heat source autonomous heating schemes

One of the priority tasks of improving the fuel efficiency in the Russian Federation is the development of district heating systems. Such a policy spelled out in the Federal law “On heat supply” dated 27.07.2010 No. 190-FZ, the number of bylaws and regulations of the government. However, there is strong growth of low-rise, primarily residential construction in the country. Today major Russian cities are surrounded by settlements and gardening, where the laying of heat networks economically not justified. In the current environment are higher requirements for energy efficiency schemes for Autonomous heat supply heat sources to meet the seasonal and year-round loads, and also search of alternative ways of using the heat systems with heat pumps and solar systems. The paper discusses options for using in the circuits Autonomous heating such heat sources, like traditional and condensing hot water boilers. In this experiment you performed the study on the impact of modes of heating systems to customers in fuel efficiency. This is very important for technical applications results efficient operation of the systems of Autonomous heat supply
