Systems of heat consumption of the building with heat pump that uses low-grade heat source are investigated. Effectiveness of heat consumption systems with heat pump is concluded effective for severe climatic conditions prevailing in Russia. Characteristics of heat consumption system with heat pump and the traditional heating system are compared. In this case the heat pump is used the warmth of the environment, that is why considered operating conditions for the autumn and spring. Low inertia of heat systems with heat pump compared to traditional ones during autumn and spring proved.

This paper deals with automatic control systems of heat consumption of buildings. As a method of study we used computational and theoretical method using the theory of differential equations, control theory, methods of analysis and synthesis, including the numerical experiment. In this paper, a comparison of the characteristics of an automated heat control system in buildings, using the heat pump from the low-grade heat source, as well as conventional systems, receiving heat from the CHP for heat networks. Numerical study carried out for conditions of autumn-spring period, as during the research of heat system, the environment is selected as the low-grade heat source. Moreover, It is analysed climatic conditions start of the heating period in 2014 and 2015. for the city of Samara. Based on the numerical investigation revealed that for the autumnspring period automated heat system with a heat pump has a lower inertia than a conventional system with.
