Abstract
An electrical resistance heating assembly comprises a heater ribbon woven through a first mica board. The heater ribbon extends upwardly from a top surface of the first mica board to provide heat to a fluid passing over the upwardly extending heater ribbon. The heat ribbon on an underside of the first mica board is electrically isolated by a second mica board positioned adjacent the first mica board. The first and second mica boards are held together with by a clamp-containing metal place positioned adjacent the second mica board with the clamps bent over the first mica board to keep the mica boards together.
