Abstract
A method of manufacturing a gas heater heating element including a support and channel structure with a plurality of channels formed in the monolith includes shaping an electric heating element and at least partially coating the electric heating element with at least one coating material. The at least partially coated electric heating element is positioned in a mold for producing the monolith. The monolith is produced and surrounds the at least partially coated electric heating element. The coating material of the at least partially coated electric heating element is removed. The gas heater heating element includes at least one electric heating element in the monolith and the electric heating element is guided in the plurality of channels of the support. Heat within the plurality of channels is configured to be transferred by the electric heating element to a gas flowing through the plurality of channels to heat the gas.
