The panel radiator for use in the field of heating voltage up to 1000 V, comprises an electrically conductive cellulose non-woven material (1) that forms electrical resistance required for heating, and two electrical strips (2), which electrically contact the non-woven material. The panel radiator provides infinite thermal output up to 2 kW/m 2>. The non-woven material is connected by an electric contact with a current source. The non-woven material consists cellulose fibers that contain carbon-nanotubes and nano silver. The panel radiator for use in the field of heating voltage up to 1000 V, comprises an electrically conductive cellulose non-woven material (1) that forms electrical resistance required for heating, and two electrical strips (2), which electrically contact the non-woven material. The panel radiator provides infinite thermal output up to 2 kW/m 2>. The non-woven material is connected by an electric contact with a current source. The non-woven material consists cellulose fibers that contain carbon-nanotubes and nano silver. The non-woven material is manufactured after a lyocell method. Spinning of the non-woven material takes place after a normal spinning process by an air gap, a blow spinning process, a centrifugal spinning process or nanoval process. The non-woven material has a panel mass of 40-150 g/m 2>and is spun bonded. The contact strips (2) are formed from metal wires and/or metal foil and/or metal conductive lacquer. The non-woven material is insulated completely by an electrically insulating material and waterproof material. Die Erfindung betrifft einen Flächenheizer, der für Anwendungen im Bereich von Heizspannungen bis zu 1000 V zur Anwendung kommt, erzielbare Leistungen bis 2 kW/m2 liefert und der dadurch gekennzeichnet ist, dass der für die Heizung erforderliche elektrische Widerstand durch ein elektrisch leitfähiges Cellulosevlies gebildet wird. Eingearbeitete metallische Kontakte sichern den Anschluss des leitfähigen Cellulosevlieses an eine Spannungsquelle. Beidseitig aufgebrachte Polymerfolien geben mechanischen und elektrischen Schutz und verhindern das Eindringen von Feuchte in das Cellulosevlies.
