Abstract

An electric heater (2) is manufactured comprising at least one elongate ribbon-form electrical resistance heating element (12) supported relative to thermal and electrical insulation means (8). The at least one elongate ribbon-form electrical resistance heating element (12) has at least one portion (12A; 12B; 12C) thereof overlapping and welded to at least one electrically conductive element (28A; 36A; 54) at a predetermined zone of overlap (44). A plurality of weld points (46; 46A; 46B) are provided directly between the at least one portion (12A; 12B; 12C) of the at least one heating element (12) and the at least one electrically conductive element (28A; 36A; 54) within the zone of overlap (44).
