1. An electric heater for an automobile vehicle, the electric heater comprising: an electronic controller; anda heat transmitting net comprising: a plurality of PTC-heating elements;a plurality of contact sheets;a plurality of heat dissipating fins; anda plurality of distance elements,wherein at least one PTC-heating element and at least one distance element is arranged between two adjacent contact sheets,wherein the PTC-heating elements and the distance elements between the adjacent contact sheets and the adjacent contact sheets themselves form a heating element,wherein the heating elements are connected to the electronic controller through connectors that are arranged at the electronic controller and are connected to a power supply,wherein the heat transmitting net is divided into a first area, which contains only distance elements, and into a second area, which contains PTC-heating elements and/or distance elements, andwherein the first area is arranged at a first end of the heat transmitting net that is closest to the electronic controller, and the second area is arranged adjacent to the first 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 area is positioned farther away from the electronic controller than the first area. 2. The electric heater according to claim 1, wherein the electronic controller has heat dissipating elements that extend into the first area of the heat transmitting net. 3. The electric heater according to claim 1, wherein the PTC-heating elements are distributed substantially symmetrically with respect to a centerline, which divides the heat transmitting net in 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. 4. The electric heater according to claim 1, wherein the heating elements are activatable individually through the electronic controller. 5. The electric heater according to claim 1, wherein a heating element contains the distance elements and the PTC-heating elements in an alternating order. 6. The electric heater according to claim 1, wherein the PTC-heating elements are spaced apart in a horizontal direction and/or in a vertical direction across the heat transmitting net by distance elements. 7. The electric heater according to claim 1, wherein at least two distance elements are arranged adjacent to each other in a horizontal direction and/or in a vertical direction to create a cooler spot within the heat transmitting net. 8. The electric heater according to claim 1, wherein the distance elements are electrically not conductive. 9. The electric heater according to claim 1, wherein each heating element is electrically connected to a positive pole of a power supply and a negative pole of a power supply, and wherein a heat transmitting fin acts as a conductive bridge between two adjacent contact sheets. 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.
