ABSTRACT The woven electric heater comprises warp and weft from electric current-insulating material, interwoven with formation of background and selvage. Worked into background is the weft from electric current-conductive material with formation of heating portions and insulating strips. The weft yarn from current-conductive material and the current- carrying strand have complete insulation cover, and their contact is secured by means of commutative elements fixed between the heating portions. The warp yarn has length shrinkage within 0.01-5 % at 25 to 120 degrees C, while the weft yarn is manufactured from material retaining its geometrical pattern in heating conditions.
