Chamber electric resistance furnaces (CRF), used for performing of various heating processes, are powerful consumers of electric power. During their operation, different deviations from the original construction may appear and defects, such as: defects in the insulation and the gaskets, deformations of the body, and others. They result in increased thermal flow, running from the chamber to the ambience, increased thermal losses and, as a whole, increased electric power losses. This problem is of special concern in view of current energy efficiency criteria and its solution is sought in the following directions: analysis of the energy efficiency of the furnaces at the stage of their design; analysis of the reconstruction and repair works due to worn-out equipment, consisting in replacement of thermal insulation in order to decrease the losses.

Quality management systems based on the International Standards ISO (International Organization for Standardization) is a revolutionary way to increase the competitiveness of Bulgarian companies in the energy sector on the European and international energy market. Тhe implementation of international standards and management systems is becoming a major tool to reduce production costs, increase productivity, reduce the cost of manufactured products and services through the creation of optimal models of governance and organization of the key processes in the energetic sector companies. Development and implementation of management systems, good manufacturing practices and achieving product compliance with European and international standards is a promising trend. In proposed authors post after presentation of the International Organization for Standardization ISO is studying and analyzing systems applied quality management in projects in the field of energy development.
