In many cases, domestic buildings of the central heating system (radiator) are used for heating production. Engine room is considered one of sectors the high consumption of buildings. The uses of intelligent systems in the engine room due to the unique capabilities that seem very practical. At the beginning of this article analyzes the evolution of energy demand in the domestic sector and then performance engine room intelligent systems and its role as an energy optimizer will be evaluation. Economic topic of this paper will be initial cost, payback period, calculations necessary for gas saving, cost savings resulting from reduced pollutant emissions. Studies show that implementation of optimization plans in the engine room throughout the country will be causes decreased annual gas consumption and production of carbon monoxide
