Abstract: Power feed connections and sauna heating panels include a power feed having a first insulated conductor electrically coupled to a first terminal and a second insulated conductor electrically coupled to a second terminal. The first and second terminals are electrically coupled with at least one heating element. In some cases the power feed includes a supply portion, a connection portion, and an extension portion. The extension portion has one or more conductors in a twisted configuration extending away from the first and second terminals. In some cases the power feed includes an extension conductor portion coupled to a return conductor portion in a twisted configuration. The extension portion extends away from a second terminal past a second connection point and the return portion returns back to and connects to the second connection point at the second terminal. Methods for providing power connections to heating panels are also provided.

Abstract: An infrared (IR) heating panel system comprising a thermally and electrically insulating substrate, a power buss, an at least one substrate supported IR heating element electrically coupled to the power buss, and a return element electrically coupled to the power buss and IR heating element. A printed shield substantially covers the IR heating element(s). The heating panel emits radiation when an electrical current is passed therethrough. The printed shielding layer is electrically coupled to a low impedance grounding matrix and configured to harness and shunt electrical field charges emitted by the IR heating element. Some embodiments include two or more IR heating panels coupled in an electrical parallel configuration supplied by one twisted and shielded power feed wire. Twisted two-wire shielded plus ground conductors are soldered to the corresponding IR heater solder points while simultaneously maintaining the twisted wire configuration for EMR cancellation and EF grounding shield conductivity.

Abstract: Examples of infrared heating panels are described as having a non-linear power density profile along a length of the heating panel. The power density profile can include a first power density zone and a second power density zone, each zone corresponding to an area of the heating panel having a separate power density in response to a current flow. An infrared heating panel can include multiple heating elements arranged adjacently in a row and electrically connected together by at least two power buses extending perpendicularly across the heating elements. In one example, the first power density zone is located between a first power bus and an end of the heating elements. The second power density zone can be located between the first power bus and an opposite end of the heating elements. Infrared sauna systems and methods of generating heat for a sauna are also provided.
