FIELD: heating.
SUBSTANCE: invention relates to devices for resistive heating and can be used for heating of various media, for example, air, water or oil, and can be used in industry and household. Tubular electric heater includes housing, inside which there is tube from dielectric material, rod installed inside tube, and current-conducting spiral installed on tube, and is characterized by that it contains additional current-conducting spiral, wherein tube with rod and spiral are arranged inside additional spiral, and spirals are isolated from each other, at that diameter of additional current-conducting spiral exceeds diameter of current-conducting spiral installed on tube by at least 5 %.
EFFECT: higher efficiency of heating and reduced risk of short circuit.
