A static plate heating arrangement includes a faceplate including a port extending from an exterior surface of the faceplate to an interior surface of the faceplate, a fixed resistance heater in thermal communication with the interior surface and surrounding the port, and a self-regulating heater in thermal communication with the interior surface and surrounding the fixed resistance heater. The fixed resistance heater and the self-regulating heater are electrically connected in series.

An electric heater includes a substrate and an inner plane heating element formed on one surface of the substrate. The inner plane heating element includes an inner pattern portion connecting a start point with an end point. The inner pattern portion includes a first track, a second track located outside the first track and spaced part from the first track, a first bridge connecting the first track with one end of the second track, a third track located outside the second track and spaced apart from the second track, and a second bridge connecting the other end of the second track with the third track. A first gap G1 between the first and second tracks is shorter than a second gap G2 between the second and third tracks along a virtual line crossing the first, second and third tracks and closer to the first bridge than the second bridge.

A unitary garment heating device that integrates with a garment to provide uniform heat throughout the garment. The device includes a plurality of nodes that position on various areas of the garment to distribute the heat. The nodes are fabricated from a conductive metallic yarn. A continuous conduit having no junctions carries current for generating heat, and connects the nodes to form a unitary heating device. The conduit is fabricated from the same material as the nodes, thereby forming a unitary device. The lack of junctions on the conduit helps eliminate problems such as shorts, and moisture exposure form rain or sweat. The conduit runs in a series circuitry to minimize shorts and arcing. The conduit is covered with a laminate and urethane to inhibit contact with moisture. A communication apparatus, such as a smart phone, monitors and regulates the temperature. A power supply and microprocessor are also attached.

A heater of the present invention includes jointed heat generating resistors having a positive temperature characteristic of resistance and provided between a first conductive element and a second conductive element on a substrate in a longitudinal direction of the substrate, and a plurality of heating blocks provided in the longitudinal direction, each of which is a set of the first conductive element, the second conductive element, and the heat generating resistor, and power supplied to at least one of the plurality of heating blocks can be controlled independent of other heating blocks.

An electric heater includes a substrate; and a first plane heating element disposed on one surface of the substrate, in which the first plane heating element includes a first track; a second track spaced apart from the first track; and a third track spaced apart from the second track. At least a portion of the second track is located between the first track and the third track, and the first track and the second track are connected by a first bridge, where the first bridge includes a first outer protrusion protruding toward the third track. The third track is formed with a curved portion which protrudes in an outward direction, and the first outer protrusion faces an inside of the curved portion in the outward direction and is spaced apart from the curved portion.
