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.
Claims14
A sauna, said sauna comprising:
- a seating area;
- a first halogen tube configured to generate heat towards the seating area;
- a second halogen tube configured to generate heat towards the seating area, wherein the first halogen tube is implemented an adjustable distance from the second halogen tube, and wherein the adjustable distance between the first halogen tube and the second halogen tube is configurable to tune an amount of electromagnetic field (EMF) emitted by the heater;
- and
- 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.
A sauna heater, said sauna heater comprising:
- a first halogen tube configured to generate heat;
- a second halogen tube configured to generate heat, wherein the first halogen tube is implemented an adjustable distance from the second halogen tube, and wherein the adjustable 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 to be lower than a designated amount of EMF;
- and
- 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.
