Description

The Koza K11 stands out not only for its modern design, but also for its high wood-burning efficiency, making it an attractive and functional heating solution. Thanks to an innovative design approach and the use of advanced technologies, this stove blends perfectly with various interior styles while providing efficient and cost-effective heating. The K11 combines functionality with beauty, becoming an elegant decorative feature in any interior.

The K11 stove ensures ease of use at every stage. The classic front is equipped with heat-resistant ceramic glass capable of withstanding temperatures up to 600°C. The cool-handle system allows the handle to be removed, ensuring it remains sufficiently cool for safe opening and closing of the stove door. The ash drawer makes it easy to remove wood-burning residues, helping maintain cleanliness and order around the stove. Additionally, the decorative fence not only enhances the aesthetic appeal but also helps keep the area clean and prevents logs from falling out.

The stove meets the requirements of the Ecodesign (Ekoprojekt) directive as well as the strict German BlmschV II standard. It has also been designed to comply with the rigorous environmental standards of Flamme Verte, ensuring high efficiency, clean combustion, and reduced emissions. This allows you to enjoy a cozy home atmosphere while minimizing your environmental impact.

We are confident in the quality of our products. By choosing our stove, you ensure peace of mind, trouble-free operation, and complete satisfaction with your purchase.
