Abstract

A vehicle heater comprises a main body carrying a non-intrinsically safe heat conductor layer, and a sensor device allocated to the heat conductor layer and provided to detect an exceedance of a temperature threshold value. The sensor device comprises a sensor layer arranged on the side of the heat conductor layer facing away from the main body which is monitored for current flows which may occur substantially in the direction of its surface normal. In a method for producing a vehicle heater a main body of the vehicle heater is equipped with a non-intrinsically safe heat conductor, and a sensor device for detecting exceedances of a temperature threshold value. A sensor layer provided to be monitored for current flows which may occur substantially in the direction of the surface normal of the sensor layer is allocated to the heat conductor layer on its side facing away from the main body to form the sensor device.
