  • Publication number: 20240130929
    Abstract: Sauna heaters are used to generate heat for saunas. Sauna heaters include a first halogen tube configured to generate heat, a second halogen tube configured to generate heat, wherein the first halogen tube is implemented a distance from the second halogen, and wherein the distance between the first halogen tube and the second halogen tube is configurable to adjust an amount of electromagnetic field (EMF) emitted by the heater. Sauna heaters also include a source of alternating current electrically coupled to the first halogen tube and the second halogen tube such that the source of alternating current is configured to provide the first halogen tube and the second halogen tube with a current, wherein the current powering the first halogen tube is out of phase with the current powering the second halogen tube.

  • Publication number: 20230232505
    Abstract: Systems may include a heater including a plurality of heating elements that may include a first heating element configured to generate heat based on a first current, and a second heating element configured to generate heat based on a second current. Systems may further include an electromagnetic (EM) radiation reducing device configured to cancel electromagnetic emissions from the heater. The EM radiation reducing device may include a first EM radiation reduction element positioned adjacent to a first side of the heater, and a second EM radiation reduction element positioned adjacent to a second side of the heater, where the first and second EM radiation reduction elements have geometries configured based, at least in part, on the heater.
