The article deals with the methods of transfer of thermal energy of electric heaters to the nodes and devices of non-pressurized spacecraft, which are part of the spacecraft in the target orbits in the conditions of regular use. The basic technical characteristics of perspective electric heaters for operating conditions are developed, the model of regular position of electric heaters allowing to define ways of increase of efficiency and efficiency of electric heaters is developed. The main results of the development of flexible film electric heaters various design using materials produced by the domestic industry and manufactured using a new method based on the method of photolithography and etching the resistive layer, allowing to implement new functionality and improve efficiency of electric heaters, the experiments confirming the calculations in conditions simulating operational influences on electric heaters. The using of flexible film electric heaters increased efficiency in the existing and future spacecraft can improve the efficiency of the thermal control system as a whole, improves manufacturability.
