Abstract
A tubular thin film resistance heater including a substrate ( ) having an electrically non-conductive surface on which is deposited a thin film electrical conductor ( ), such as tin oxide. A pair of electrical terminals ( ), preferably bus bars, are electrically connected at spaced apart locations on the conductor ( ), such as at longitudinal spaced opposed ends or at circumferentially spaced opposed edges of the conductor ( ). The thin film conductor ( ) is molecularly bonded to the substrate ( ) for durability and efficient heat transfer. A method of forming a tubular thin film resistance heater also is disclosed.
