Classic Sauna Heaters

Classic Heaters. Evolving Control Technology.

While the classic sauna heaters have remained largely the same for decades, technology has made controls even more simple, reliable, intuitive, and now more accessible. Dialed controls have been replaced with digital and touch pad technology that result in a user friendly experience and less downtime for maintenance or troubleshooting and happier sauna bathers.

Woodburning Sauna Heaters

The Heart of the Sauna Experience

Traditional woodburning saunas really go to the heart of the pure sauna experience: the incomparably soft heat, lush hiss of steam and relaxing crackle of a wood-fueled fire... even the ritual of tending the fire. It is a heritage sauna enthusiasts have treasured for thousands of years. Captured and reinterpreted for modern living in today's Helo wood burning heaters.

The "Coanda" Effect

The patented air channeling system between the outer shroud and inner firebox allows heated air to efficiently pass through the rock chamber for faster and more even heating of the rocks. This improves steam generation and air circulation in the sauna. As the fire dies down, the firebox walls cool and the air stops rising through the rock compartment and is redirected to the side vents. We call this the “Coanda” effect. The stones retain their heat longer, providing long-lasting comfort while using firewood as efficiently as possible.
