Don't Settle For a Hot Room

Saunum Air Flow

Electric saunas have one big problem.

Stratification.

Hot air rises and becomes stale without combustion from a wood fire.  It’s not uncommon for an electric sauna to be 200 degrees at head height and under 100 degrees at foot height. 

The best oxygen is low, while the best heat is high, where your head is most sensitive to heat.

Saunum Air is the only heater designed to solve heat stratification in saunas, providing even heat and oxygen levels throughout the space.

The World’s Most Advanced Sauna Solution

These state-of-the-art sauna heaters deliver a superior sauna experience, thanks to the patented air blending technology that mixes cool, oxygen-rich air from the floor with hot, oxygen-poor air from the ceiling. This technology ensures consistent temperature and oxygen levels throughout the sauna, improving comfort and enhancing your sauna sessions.

Saunum Air Series is available in elegant Nordic Black and polished Stainless Steel finishes, a nod to Scandinavian design aesthetics. They come with an adjustable valve for cool air intake, located 12 inches off the floor, and an output for blended air, ensuring perfect air circulation.

 

A Personalized Sauna Environment

  • Classic Nordic Steam Sauna
    • for temperatures from 140°F – 194°F. Valve of the Climate Device open to 25% with speed level 1.
  • Humid Steam-rich Sauna
    • for temperatures from 113°F – 140°F. Valve of the Climate Device open to 100% with speed level 2 or 3.
  • Mild, Relaxing Sauna
    • for temperatures from 104 °F – 131 °F. Valve of the Climate Device open to 25% with speed level 1.

The Standard Saunum Air Series can accommodate rooms from 123 to 353 cu. ft., with each model designed for a specific range: the Saunum Air 5 for 106-212 cu. ft., the Saunum Air 7 for 177-282 cu. ft, and the Saunum Air 10 for 247-424 cu. ft. All models operate on 240VAC and are UL-certified, assuring safety and reliability.

The newest Saunum Air L series comes in three additional sizes.  The Saunum Air 10 L 247-459 cu. ft, The Saunum Air L 13 for 317-565 cu. ft, or the Saunum Air L 15 for 459-741 cu ft.  

*Contact us to calculate the impact of glass and uninsulated materials to best size your saunum.

Each Saunum Air model features a large stone capacity, ranging from 99 lbs to 231 lbs, producing softer, more even heat. The unique Himalayan Salt Reservoir, included with all models, releases healthful salt ions throughout the room, while an optional aromatherapy system enhances the sauna experience further. The Saunum Air Series also offers a Wi-Fi control option for convenience and customizability.

With the Saunum Air Series, you can experience the best of sauna bathing, delivered through innovative technology and elegant design. Transform your sauna sessions with Saunum – it’s all about the air you heat, feel, and breathe.

Calculating You Sauna Volume to Size Your Saunum Air and Air L Heater

Selecting the right heater for your sauna involves considering the room's volume and the materials used in its construction. Materials like glass, tile, brick, concrete, or stone, which do not retain heat well, necessitate a more powerful heater.

Step-by-Step Calculation:

  1. Determine Room Volume: Calculate the room's volume by multiplying its height (Z), width (X), and length (Y) in feet. This gives you the basic cubic volume of your sauna.

  2. Account for Specific Materials: If your sauna includes walls made of glass, tile, brick, concrete, or stone, you need to adjust the volume calculation. First, calculate the total square footage of these materials by adding up their surface areas. Then, for each square foot of these materials, add an additional 3.9 cubic feet to the room's volume. This compensates for their lower heat retention.

  3. Adjust for Log Walls: If your sauna has log walls, take the room's volume from step 1 and multiply it by 1.5. This accounts for the insulating properties of logs.

  4. Final Volume: The resulting figure from these calculations represents the sauna's adjusted volume, which you can use to select the appropriate heater size. If your calculated volume is between two heater sizes, opt for the larger size to ensure adequate heating.

Sauna Room Heights:

  • Standard sauna room heights range from 83 to 91 inches.
  • For installations involving the Saunum Air L climate device, the minimum ceiling height is 71 inches.

Refer to Table 1 in the provided pages (12-13) for optimal sauna sizes for the Saunum Air climate device. This guide ensures you choose a heater with sufficient output for your sauna's specific conditions and materials.

 

Q&A

Saunum Air is the US version of the Saunum primary with UL listings.  The tradeoff with UL listings is they require a maximum temperature of 194 degrees Fahrenheit, while European models can be programmed to 230f.  However, with air movement and a more evenly heated sauna, you’ll find 194 degrees in the Saunum is a far more envigorating experience than any other heater on the market.  

Compared to the solid black finish, the stainless steel rock basket distributes more air from the side of the heater, resulting in greater side clearances and higher minimum ceiling heights.  The stainless steel options can handle larger spaces as well.

The minimum ceiling heights are to provide the minimum safety clearances and are not necessarily the physical limitations of the heater.  

Yes, the Saunum AIRIQ WiFi upgrade lets you control the Saunum from your phone.  

No, the Saunum distributes power to the fan.

We are working on pairing Saunum with our larger SaunaLife and Thermory barrel saunas.  It may require a heat shield and other considerations.  Please get in touch with us for details.  

Yes, there is a Saunum option for most indoor and outdoor Auroom and SaunaLife saunas.  Please get in touch for options.

There’s a Saunum dealer in Australia:  https://www.saunum.com.au/

We’ll have to stop free shipping (a $500 value) in the coming weeks.  Moreover, the stock is tight in North America and we are unsure when more will arrive.  We recommend getting your orders in now for fast and free shipping.

Saunologia's Saunum Review

Saunologia is a Finnish sauna design company that helps customers around the world to secure healthy, sustainable and functional sauna designs. It was founded by Dr. Lassi A Liikkanen and is based in Finland. It features some of the best information about sauna design available in print and online. Sauna Marketplace is not affiliated with Saunologia.

Learn more about Liikkanen's work by reading his highly acclaimed The Secrets of Finnish Sauna Design.

Before the introduction of the Saunum circulating air heater, Erkka Suominen, a long-time sauna and hockey enthusiast, had a traditional setup in his small apartment sauna with a Harvia Cilindro. "I knew there was room for improvement," Erkka expressed, highlighting his discontent with the uneven heat distribution in his sauna, forcing him to uncomfortably raise his feet to the upper platform for a smoother sauna experience.

In late 2022, Saunologia gave him an opportunity to test out the Saunum circulating air heater, which draws in hot air and moisture from the edge of the ceiling and blows it down to the floor, evening out temperature differences and moving the steam lower in the sauna. The experiment was carried out in November-December 2022, with the heater noticeably improving Erkka's sauna comfort. "Now, I'm able to spend a longer time in the sauna than before," he stated.

A month into the trial, Erkka found that he could create different sauna conditions with the Saunum heater by changing the combination of the sauna room's target temperature and fan strength. After the experiment, he also noted a significant reduction in temperature differences within the sauna, saying, "Before, the temperature difference from the ceiling to the footboard was more than 30 C, but now it's below 15 C."

Six months after the beginning of the experiment, Erkka was delighted with the Saunum air heater's performance. He remarked, "Saunum rocks and is in heavy use." Moreover, he found the Saunum remote control practical, allowing him to turn on the sauna from his phone.

In summary, the introduction of the Saunum circulating air heater significantly improved the sauna experience for Erkka, enhancing the heat distribution and allowing him to spend more time comfortably in the sauna.

PLAN THE WHOLE SAUNA

The room and heater still have to work as one system.

Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.
