Yes, as a wood-burning stove, proper ventilation is essential for safety and optimal performance. Ensure there is a sufficient air inlet to feed the fire and an exhaust to remove smoke effectively.
Seasoned hardwoods, like birch or oak, are recommended as they burn longer and hotter, providing consistent heat output and creating a pleasant aroma, enhancing your sauna experience.

Yes, it is designed with safety in mind for both home and commercial use. It must be installed according to the manufacturer's clearance guidelines around the walls and ceiling to ensure user safety.
