Saunum Air 5 Sauna Heater

The Saunum Air 5 Sauna Heater is a 5 kW wall-mounted electric sauna heater with Saunum's climate equalizer built in, for rooms of 106 to 212 cu ft. It runs on 240V single phase and draws 20.63 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.

This equalizes room temperature by more than 60% for a significantly better sauna experience. You'll enjoy longer, more satisfying sauna sessions with more intense sweating. All sauna bathers have experienced the same issue - extreme variance in temperature and oxygen from the ceiling to the floor. The temperature at the ceiling can often exceed 200°F, while at the floor it will be under 100°F, causing your feet to feel uncomfortably cool and your head to be too hot. The temperature and oxygen level should be more consistent throughout.

• 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 an elegant black steel finish, Saunum combines Scandinavian design and quality materials.
• 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. Large 110 pound stone capacity (required 4 boxes sold separately).
• Himalayan Salt Reservoir - Himalayan Salt Spheres are positioned within the air stream so that salt ions are propelled throughout the sauna to deliver health benefits.
• 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.

UL listed. Saunum's certificate of compliance covers the Air 5, Air 7 and Air 10 as permanently installed wall-mounted sauna heaters, UL-US-2310119-2 in the US and UL-CA-2308849-2 in Canada, to UL 875 9th edition (US) and CSA C22.2 No. 164-18 (Canada).

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.
