Cozy Heat Thru-Wall Sauna Stove

The through-the-wall design allows you to load wood from outside the sauna room. This keeps your sauna clean by preventing ash and debris from entering the bathing space and allows you to tend the fire without interrupting anyone inside.

The choice depends entirely on the cubic footage of your sauna room. As a general rule, the 12kW unit is suitable for smaller, standard-sized home saunas, while the 18kW model is designed for larger spaces that require more heating capacity to reach optimal temperatures.

Yes, because this is a wood-burning appliance, it must be installed with a chimney system rated for solid fuel appliances. You should consult with a local professional or your local building codes to ensure your venting setup meets safety requirements for wood-burning heaters.

The 12kW model holds 175 lbs of stones, while the 18kW model holds 240 lbs. A larger stone capacity is crucial for traditional sauna experiences because it retains heat longer and allows for more consistent steam generation when you pour water over the rocks.

While this model is engineered with minimal safety distance requirements compared to many traditional heaters, you must still adhere to the manufacturer's specific clearance guidelines for combustible materials. Always check the installation manual provided with your unit to ensure your sauna layout complies with these safety distances.

Maintenance is straightforward, primarily involving regular ash removal from the firebox and occasional inspection of the stones. Because the unit is constructed from high-efficiency steel, it is designed for durability and longevity with standard care.
