An electric resistance heater array having an open metal frame with multiple heater wires of heavy gauge, U-shaped Nichrome wire that are vertically spaced across the panel. The lower vertical portions of the heater wire are encased in ceramic sleeves which insulate the wire from the small apertures in the metal frame that support the wire by its constraints upon side to side and fore to aft movement.
