  "textContent": "A positive temperature coefficient electric heater for a vehicle includes a support part, a control circuitry, and a first and a second radiating layers overlapping one another, each radiating layer having a plurality of heating rods extending from the support part and connected in parallel to the control circuitry. Each radiating layer has a first layer sector and a second layer sector controlled independently of one another. The radiating layers may be controlled independently of one another. In the first radiating layer, the second section of the heating rods is capable of generating greater thermal power than the first section of the heating rods and, in the second radiating layer, the first section of the heating rods is capable of generating greater thermal power than the second section of the heating rods.",
