When people consider adding a sauna to their home or wellness routine, one of the first questions that comes to mind is about cost and efficiency. Saunas provide incredible health benefits, but they also use electricity to generate heat. That naturally leads to the big question: Do infrared saunas use less electricity than traditional saunas? At Salus Saunas, we know how important energy efficiency is to our customers, so let’s explore the differences and help you make an informed decision.
Understanding the Basics: Infrared vs. Traditional Saunas
Before diving into energy use, it’s important to understand how each sauna type works.
Traditional Saunas
Traditional saunas heat the air inside the sauna room using an electric heater (or sometimes wood). The heater warms the stones, which then radiate heat, creating a high-temperature environment. This method relies on heating the air first and then transferring that heat to your body. Traditional saunas typically operate between 170°F and 200°F, making the entire space hot and steamy.
Infrared Saunas
Infrared saunas work differently. Instead of heating the air, infrared heaters emit infrared light, which penetrates your skin directly to raise your core body temperature. This process allows infrared saunas to operate at lower ambient temperatures, usually between 120°F and 150°F, while still delivering powerful therapeutic effects.
Comparing Energy Consumption
The main factor in electricity usage comes down to how each sauna produces and maintains heat.
Wattage Requirements
- Traditional Saunas: These usually require larger heaters, often ranging from 6 to 9 kilowatts (kW), depending on the sauna size. Heating the air and maintaining such high temperatures demands significant power.
- Infrared Saunas: Infrared panels generally require much less power, often ranging from 1.5 to 2 kW for a two-person sauna, with larger models using up to 3 or 4 kW. That’s substantially less than traditional sauna heaters.
Heat-Up Time
- Traditional: A traditional sauna can take 30–45 minutes to reach full temperature. During that time, the heater continuously draws energy.
- Infrared: Infrared saunas heat up in about 10–15 minutes. Since they don’t need to warm the entire room to high levels, they reach usable temperatures much faster, reducing overall electricity use.
Session Duration
Because infrared heat penetrates the body more efficiently, users often spend less time in an infrared sauna to achieve similar results. Shorter sessions combined with lower energy demands make infrared saunas the clear winner in terms of efficiency.
Cost of Running Each Sauna
Energy efficiency doesn’t just benefit the environment; it also impacts your utility bills. Because electricity rates vary depending on your location, sauna size, and usage habits, costs can differ. The table below provides a general estimate of electricity consumption and average per-session cost ranges.
| Sauna Type | Typical Power Usage | Average Session Duration | Estimated Cost per Session* |
|---|---|---|---|
| Traditional Sauna | 6–9 kW | 30–45 minutes | $1.00 – $2.00 |
| Infrared Sauna | 1.5–3 kW | 20–30 minutes | $0.25 – $0.75 |
Estimates are based on common electricity rates in the U.S. and may vary by region.
If you plan to use your sauna several times per week, those differences in consumption and cost can add up significantly over time.
Health Benefits and Comfort Considerations
While the focus here is on energy use, it’s worth noting that infrared saunas also provide unique comfort and health advantages:
- Gentler Heat: Infrared saunas operate at lower temperatures, making them more comfortable for longer sessions without sacrificing benefits.
- Deeper Penetration: Infrared light penetrates muscles and joints, providing relief at a cellular level.
- Sustainable Use: Because they are more energy-efficient, it’s easier to use them frequently without worrying about large spikes in your energy bill.
Long-Term Value
When you consider purchasing a sauna, it’s more than just a one-time expense. Over years of ownership, operating costs matter just as much as upfront costs.
- Traditional Sauna Value: Traditional saunas deliver the authentic high-heat experience many people love, but they do require more electricity and longer warm-up times.
- Infrared Sauna Value: Infrared saunas may be the smarter investment for long-term savings, offering lower operating costs, quicker sessions, and a gentler yet effective experience.
With Salus Saunas, you’ll find a range of options designed to balance performance, comfort, and efficiency—so you can choose the sauna that best fits your lifestyle and budget.
Sauna Electricity Consumption: What You Need to Know
1. How does the room size affect sauna electricity consumption?
The size of your sauna directly impacts electricity usage. Larger spaces require more power to reach and maintain optimal heat levels, regardless of whether it’s infrared or traditional. For homeowners, choosing the right heater size ensures energy efficiency without sacrificing comfort.
2. Can using a sauna frequently raise my electricity bill significantly?
Frequent sauna use can increase your monthly energy bill, but the extent depends on the type of sauna and session length. Infrared models typically have a minimal effect due to their lower power demand, while traditional saunas may add more noticeable costs if used daily.
3. Do modern saunas come with energy-saving features?
Yes, many modern saunas include energy-efficient designs such as insulated panels, programmable timers, and eco-friendly heaters. These features minimize unnecessary power draw and help users control both cost and consumption.
4. How do electricity rates in my area influence sauna costs?
Electricity rates vary widely across regions. A household in a city with high per-kilowatt-hour charges will pay more per sauna session than one in an area with lower rates. This is why estimating sauna operating costs should always take local utility rates into account.
5. Does insulation in a sauna impact electricity usage?
Absolutely. Proper insulation helps maintain heat more effectively, which reduces the workload on the heater. A well-insulated sauna retains warmth longer, translating to fewer energy spikes and lower long-term costs.
6. Are hybrid saunas more or less efficient than single-type models?
Hybrid saunas combine infrared panels and traditional heaters, offering flexibility. While they may consume more electricity than infrared-only models, they are often more efficient than running a traditional sauna exclusively because users can switch between modes depending on their needs.
7. How long does it take for electricity consumption to balance out the investment in a sauna?
The “payback period” depends on frequency of use, electricity costs in your area, and whether you choose infrared or traditional. Many homeowners find that the efficiency of infrared saunas offsets operating costs over time, making them a smart long-term investment.
8. Can smart controls help reduce sauna electricity usage?
Yes, smart controls allow you to preheat at specific times, set session durations, and even remotely monitor energy consumption. This level of precision prevents unnecessary heating and ensures you’re only using electricity when you truly need it.
9. How does sauna placement in the home affect efficiency?
Location matters. Placing a sauna in a well-insulated indoor space reduces heat loss compared to installing it in a cold garage or outdoor area. The more stable the surrounding temperature, the less electricity the sauna needs to maintain consistent warmth.
10. What’s the best way to estimate my sauna’s electricity use before purchase?
To estimate usage, check the sauna’s wattage rating and multiply it by your local electricity rate and expected session length. For example, a 2 kW infrared sauna used for 30 minutes will consume 1 kWh. This simple calculation helps you forecast operating costs accurately. One helpful resource is the Huum Sauna Calculator, which allows you to enter your sauna’s dimensions and structural details to get an estimate of how powerful the heater should be.
The Clear Winner in Energy Efficiency
So, do infrared saunas use less electricity than traditional saunas? The answer is a resounding yes. Infrared saunas require less power, heat up faster, and cost significantly less to operate per session. They’re not only a cost-effective choice but also a sustainable one, aligning with the growing demand for eco-friendly wellness solutions.
By choosing an infrared sauna from Salus Saunas, you’re investing in both your health and your future utility savings.
