1. A method of manufacturing a gas heater heating element including a support and channel structure with a plurality of channels formed in a monolith, comprising:
shaping an electric heating element;
at least partially coating the electric heating element with at least one coating material;
introducing the at least partially coated electric heating element into a mold for producing the monolith;
producing the monolith to surround the at least partially coated electric heating element; and
removing the coating material of the at least partially coated electric heating element,
wherein the gas heater heating element includes at least one electric heating element in the monolith,
wherein the electric heating element is guided in the plurality of channels of the support and channel structure, and
wherein heat within the plurality of channels is transferred by the electric heating element to a gas flowing through the plurality of channels to heat the gas.
