Quick answer

Electrical needs range from a household outlet for some blankets and infrared cabins to a dedicated hard-wired 240V circuit for traditional heaters. Use the exact model manual and a licensed electrician; the heater's kW rating, breaker, conductor, GFCI requirements, disconnect, clearances, and local code all matter.

What to bring the electrician

Provide the exact model, heater manual, nameplate load, control system, lighting load, installation location, cable route, and manufacturer clearance drawing. Do not size a circuit from a category page or a similar model.

  • Confirm dedicated-circuit requirements.
  • Ask whether the listed load is continuous.
  • Separate lighting and heater requirements where the manual does.
  • Do not use extension cords unless the manufacturer explicitly allows them.
