Cozy Heat O Thru-Wall

The through-the-wall design allows you to load firewood from outside your sauna room. This keeps your sauna interior free of wood debris, ash, and clutter, ensuring a cleaner and more relaxing environment.

This unit is rated for sauna rooms between 317 and 635 cubic feet. If your sauna falls within this range, the 18 kW output will provide optimal heating performance.

Yes, this heater is specifically optimized for steam generation. The design allows you to pour water directly over the stones to produce intense, traditional steam without compromising the unit's durability.

The firebox accommodates firewood up to 15.74 inches in length. Using logs within this size limit ensures proper combustion and efficient heat output.

Yes, the circular rim is engineered to promote better airflow and heat distribution throughout the sauna. It helps circulate heat more evenly compared to standard box-style heater designs.

Because this is a through-the-wall unit, installation requires cutting an opening in your sauna wall to accommodate the loading tunnel. It is a floor-mounted unit, so ensure your sauna floor is level and capable of supporting the 181-pound weight.
