FIELD: electrical engineering; electric heaters, including electric fans. SUBSTANCE: device has insulating former and coiled resistance unit; former has base that carries at least two supporting members mounted in a spaced relation to each other to form slots which make it possible to place adjacent turns of resistance unit coil on supporting members in opposing directions. During manufacture, each turn is followed by transfer of resistance unit through slot over diagonal line with one-pitch displacement. Resistance unit coil can be placed not only around insulating former but also in central part of space inside former. EFFECT: reduced size and mass for same technical characteristics. 2 cl, 7 dwg
