The electrothermal complex on a basis of face electrosteam and gas generator for thermal influence on productive layers of high viscosity oil and a control system of this complex is considered. This control system allows to support automatically the set technological parameters depending on operating modes of a complex.

The basic ways of control of power, transferred to a heating element of coal-face electrothermal devices are considered. Research of influence of work of a heating element on quality of the electric power in distributing networks is carried out.
