1. An electric heater for an automobile vehicle, the electric heater comprising: an electronic controller; anda heat transmitting net having a plurality of PTC-heating elements, a plurality of contact sheets, and heat dissipating fins, the PTC-heating elements being respectively arranged between two adjacent contact sheets and form a heating element with the contact sheets,wherein a portion of the contact sheets are connected to connectors that are arranged at the electronic controller and are connected to either a positive pole of a power supply or a negative pole of a power supply and are arranged in an alternating order, andwherein a quantity of connectors that are connected to a positive pole of a power supply and a quantity of connectors that are connected to a negative pole of a power supply differs by one,wherein the heat transmitting net has a first heat transmitting area and a second heat transmitting area, and wherein the PTC-heating elements are arranged only within the second heat transmitting area, andwherein the first heat transmitting area is arranged at a first end of the heat transmitting net that is closest to the electronic controller, and the second heat transmitting area is arranged adjacent to the first heat transmitting area and extends to a second end of the heat transmitting net that is opposite the first end of the heat transmitting net, such that the second heat transmitting area is positioned farther away from the electronic controller than the first heat transmitting area. 2. The electric heater as claimed in claim 1, wherein the first heat transmitting area has a plurality of distance elements that are arranged between adjacent contact sheets such that they create a distance between these adjacent contact sheets. 3. The electric heater as claimed in claim 1, wherein the electronic controller comprises heat dissipating elements, which extend into the first heat transmitting area of the heat transmitting net. 4. The electric heater as claimed in claim 1, wherein a portion of the contact sheets protrude from the heat transmitting net and are connected to the connectors of the electronic controller, and wherein a number of protruding contact sheets is equal to a number of connectors. 5. The electric heater as claimed in claim 1, wherein the PTC-heating elements are distributed substantially symmetrical with respect to a centerline, which divides the heat transmitting net into a left area and a right area, and wherein the centerline runs parallel to the contact sheets from the first end of the heat transmitting net to the second end of the heat transmitting net. 6. The electric heater as claimed in claim 1, wherein at least one heating element has PTC-heating elements, which are arranged in the second heat transmitting area of the heat transmitting net, and wherein distance elements are arranged in the first heat transmitting area and the second heat transmitting area of the heat transmitting net. 7. The electric heater as claimed in claim 1, wherein the heat transmitting net is connectable to the electronic controller in two different orientations, and wherein the first orientation and the second orientation differ in that the heat transmitting net is flipped about 180° around a centerline of the heat transmitting net. 8. The electric heater as claimed in claim 1, wherein the heating elements are activated individually through the electronic controller. 9. The electric heater as claimed in claim 1, wherein the heating elements are activated through the electronic controller such that the heat production of the heating elements and the heat distribution is independent of an orientation of the heat transmitting net relative to the electronic controller. 10. The electric heater as claimed in claim 1, wherein the heat transmitting net has an even number of contact sheets. 11. The electric heater as claimed in claim 1, wherein the contact sheets are divided into pairs of contact sheets, wherein a first contact sheet of each pair of contact sheets is connected to a respective connector and wherein the heat dissipating fins are provided between the first contact sheet and a second contact sheet of each pair of contact sheets. 12. The electric heater as claimed in claim 2, wherein the distance elements do not generate heat.
