Abstract: To improve environmental protection from hydrocarbon emissions particularly from vehicles a heater (1) for fluids comprising heating elements (2, 2') of an electrically conductive monolith, wherein the heater (1) comprises a passageway for the fluid to be heated with a defined flow direction of the fluid during heating operation, the heater (1) comprising at least two heating elements (2, 21) arranged side by side inside the passageway, so that they are arranged in parallel with respect to the fluid flow, is proposed improved in that one of the at least two heating elements is a controlled heating element (21), which has a slightly larger heating power, and a temperature sensor (19) is provided at or close to the downstream end (23) of the controlled heating element (2'), and wherein the temperature sensor (19) is connected to a control means (11) for temperature control during heating operation of the heater (1); and a method of operating such a heater (1).
