Saunum Air L 10 Sauna Heater

The Saunum Air L 10 Sauna Heater is a 10 kW wall-mounted electric sauna heater with Saunum's climate equalizer built in, for rooms of 283 to 494 cu ft. It runs on 240V single phase and draws 41.25 A, and it needs the AirIQ control and stones, both sold separately.

A fan inside the heater draws the scorching air trapped at the ceiling down a telescopic intake, mixes it with the cooler, more oxygenated air at floor level, and pushes the blend back out across the room. The point is to close the gap between the temperature at your head and the temperature at your feet, which in an ordinary sauna can be over 100°F.

The large stone volume of the Saunum Air L 10 and the patented air-blending system ensure exceptional steam that is soft and long, and evenly distributed throughout the sauna.

• Air Mixing Technology - Saunum patented air blending system mixes cold oxygen-rich air from the floor with hot oxygen-poor air off the ceiling to solve the discomfort so many associate with sauna.
• European Design - With elegant black steel finish, Saunum combines Scandinavian design and quality materials. Select the the simple elegance of the Nordic black steel body.
• Massive Stone Capacity - Stones are the heart of a Nordic sauna. Ample stones result in softer, more even heat, and can produce more luxurious steam. The Air L boasts a massive 180 pound stone capacity (required 6 boxes sold separately).
• Himalayan Salt Reservoir - Saunum's Himalayan salt tray is positioned within the air stream so that salt ions are propelled throughout the sauna to deliver health benefits more effectively.
• Dry your Sauna - Go ahead, toss water onto the rocks! Saunum is engineered for water-tossing, and when you're done enjoying the steam, the patented fan system will conveniently help dry your sauna.

Two things are not in the box and the heater will not run without them.

Saunum states in this model's installation manual that it is built to UL 875 and CSA C22.2 No. 164. Its published UL certificate names the Air 5, Air 7 and Air 10 only, so we do not describe this model as UL listed. Ask us if your inspector needs a certificate for this exact model.

The distances Saunum publishes in the installation manual for this series. The fan needs clear air in front of it or the equalizer cannot do its job.

Saunum publishes no separate rear or floor clearance for these heaters — they hang on the wall. Follow the mounting height and fixings in the manual.

Saunum lists these as options for this model.

• Hardwired on a dedicated circuit by a licensed electrician. The electrical connection is at the bottom rear of the heater.
• Load the stones loosely so air moves between them, and keep the air intake and outlet clear — the equalizer is a fan, and a blocked fan does nothing.
• Saunum requires a completed installation report signed by the electrician for the warranty to stand.
