If you want the feel of a traditional wood-fired sauna, the COZY 12 SW is built around the essentials: stone mass, consistent heat, and the ability to generate steam by ladling water over hot stones. With 11.5 kW of output and a target sauna size of 6–12 m³, it supports classic home sauna rooms where steady warmth and responsive “löyly” matter.
Cozy Heat’s approach emphasizes documented performance targets and installation guidance, including defined safety distances and ventilation considerations for wood-fired sauna rooms. The stove platform also specifies durability-focused details like a 5 mm stainless steel flame cutter in the hottest zone of operation and a 24-month manufacturer warranty.
For long-term ownership, the COZY 12 SW includes the core stove components and instructions needed for planning and install, while leaving stone selection to your build preferences (within the documented stone size range). This makes it a straightforward fit for builders who want a traditional stove experience with clearly defined operating and installation expectations.
