Abstract
An exhaust gas heater for an exhaust gas system of an internal combustion engine includes a carrier arrangement and a heating conductor arrangement carried on the carrier arrangement. The heating conductor arrangement has at least one heating conductor. At least one carrier-arrangement supporting unit is provided for carrying the heating conductor in an electrically insulated manner with respect to the carrier arrangement. The carrier-arrangement supporting unit includes at least one of the following: an insulating coating applied to the carrier arrangement; and, an insulating coating applied to the heating conductor supported on the carrier arrangement via the carrier-arrangement supporting unit.
