Cozy Heat SW Thru-Wall

The through-the-wall configuration allows you to load wood from outside the sauna room. This keeps your sauna interior free of ash and debris while maximizing the available floor space inside.

The Cozy Heat SW is rated for sauna volumes between 317 and 635 cubic feet. It is best to calculate your total cubic footage, including any uninsulated stone or glass surfaces, to ensure it fits your specific room size.

Because this is a wood-fired unit, it requires a properly installed chimney system that meets local building codes. We recommend consulting with a certified installer to ensure your venting setup complies with safety standards for wood-burning appliances.

With a 160 kg stone capacity, this heater holds a significant amount of thermal mass. This allows for a more consistent, gentle heat and produces a much smoother, longer-lasting steam when you ladle water over the stones.

BIMSCH certification indicates that this heater meets strict German environmental standards for emissions. It confirms that the stove is engineered to burn wood efficiently, resulting in cleaner operation and lower particulate output compared to non-certified models.

Yes, while the design is compact, you must adhere to the manufacturer's specified safety distances from combustible materials. Always check the installation manual for the exact clearance dimensions required for the walls and ceiling in your specific sauna layout.
