Abstract: A heater assembly for a haircare appliance includes an air duct defining an air flow path extending from an upstream end to a downstream end; a first heater element positioned in the flow path, the first heater element having a first electrical path defined between cut-outs in a first sheet, the air flow path extending through said cut-outs; and a second heater element positioned in the flow path downstream of the first heater element, the second heater element having a second electrical path defined between cut-outs in a second sheet, the air flow path extending through said cut-outs. The thickness of the first sheet is different to the thickness of the second sheet.

Abstract: A heater assembly for a haircare appliance includes an air duct defining an air flow path extending from an upstream end to a downstream end; a first heater element positioned in the flow path, the first heater element having a first electrical path defined between cut-outs in a first sheet, the air flow path extending through said cut-outs; and a second heater element positioned in the flow path downstream of the first heater element, the second heater element having a second electrical path defined between cut-outs in a second sheet, the air flow path extending through said cut-outs. The first electrical path has a first width and the second electrical path has a corresponding second width which is different to the first width.

Abstract: A heater assembly for a haircare appliance includes an air duct defining an air flow path extending from an upstream end to a downstream end; a first heater element positioned in the flow path, the first heater element having a first electrical path defined between cut-outs in a first sheet, the air flow path extending through said cut-outs; and a second heater element positioned in the flow path downstream of the first heater element, the second heater element having a second electrical path defined between cut-outs in a second sheet, the air flow path extending through said cut-outs. The heater assembly includes electrical circuitry for connection to a power source. The first and second electrical paths are provided in respective first and second circuit branches which are connected in electrical parallel within said circuitry.
