On average, a 4-person electric sauna can consume between 4.5 to 6 kilowatt-hours (kWh) per hour of use. For context, running such a sauna for one hour daily would add about $50 to $70 to your monthly electricity bill, assuming an average electricity rate of $0.12 per kWh. To minimize costs, consider using a timer to preheat the sauna only when needed and ensuring proper insulation to retain heat.
Infrared saunas, on the other hand, use infrared heaters to directly warm your body rather than heating the air. These saunas operate at lower temperatures, typically between 120°F and 150°F (49°C to 65°C), and are often praised for their energy efficiency. A 2-person infrared sauna generally consumes around 1.5 to 3 kWh per hour, significantly less than its electric counterpart. This translates to roughly $18 to $36 per month for daily one-hour sessions. Infrared saunas also heat up faster, reducing preheating time and further cutting energy use. For those prioritizing energy savings, infrared saunas are a compelling option.
While infrared saunas are more energy-efficient, the choice between the two depends on personal preference and intended use. Electric saunas provide a traditional, high-heat experience that some users prefer for detoxification and muscle relaxation. Infrared saunas, however, offer a gentler heat that penetrates deeper into tissues, making them ideal for those with heat sensitivity or joint pain. To maximize efficiency regardless of type, ensure your sauna is properly insulated, use a cover when not in use, and opt for models with energy-saving features like LED controls and low-energy heaters.
Ultimately, the electricity usage of saunas varies widely based on type, size, and usage habits. Infrared saunas are the clear winner in terms of energy efficiency, consuming up to 50% less electricity than electric saunas. However, both options can be optimized to reduce energy consumption without compromising the sauna experience.
