In another embodiment, the roofing product includes an overhang section that includes at least a portion of the heater. The roofing product can be installed, and the overhang section can be coupled to an object that extends beyond an edge of the roof or over a plane defined by a roof. Many different manufacturing techniques can be used to form the heaters.

This disclosure provides a heating device. The heating device comprises an electrically conductive fabric and first and second electrical connections. The first and second electrical connections are each connected to the conductive fabric at a first end of the device. When the electrical connections are connected to a power source current flows from the first electrical connection, though the conductive fabric and to the second electrical connection thereby generating heat.

An aerosol-generating system including a liquid storage portion is provided, the portion including a rigid housing holding a liquid aerosol-forming substrate, the housing having an opening and a fluid permeable heater assembly including a plurality of electrically conductive filaments, wherein the fluid permeable heater assembly is fixed to the housing and extends across the opening of the housing. The provided heater assembly that extends across an opening of a liquid storage portion allows for a robust construction that is relatively simple to manufacture and allows for a large contact area between the heater assembly and liquid aerosol-forming substrate. The heater assembly may be substantially flat, allowing for simple manufacture.

A heating element includes a flexible substrate, a layer of adhesive disposed on a surface of the substrate, and a continuous strand of electrically conductive wire disposed on the adhesive in a pattern of coil structures. Each coil structure includes a first coiled part and a second coiled part. The wire in the first coiled part forms a counterclockwise pattern from an outermost turn to an innermost turn of the first coiled part, and the second coiled part has an innermost turn beginning at an end of the innermost turn of the first coiled part. The wire in the second coiled part forms a clockwise pattern from the innermost turn of the second coiled part to an outermost turn. A connector segment of wire connects outermost turns of adjacent ones of the coil structures.

This disclosure relates to an auto run mode for initiating a heating cycle of a heated bedding product. A heated bedding product can include a bedding product body comprising a heating element and a controller electrically connected to the heating element. The controller can include a processing circuit, such as a microcontroller, that is configured to operate in an auto run mode in which a heating cycle of the heating element is automatically initiated in response to alternating current power being provided to the controller.
