Koza K12 - modern minimalism and the strength of cast iron

Koza K12 is a freestanding cast iron stove distinguished by its solid construction, high efficiency, and aesthetic, minimalist design. Its austere yet elegant form makes it an excellent alternative for those seeking a modern design with all the advantages of our cast iron stoves.

Thanks to its simple design, the stove blends perfectly with both traditional and modern interiors, becoming not only a heat source but also a decorative element.

Efficient heating and long-lasting warmth

The stove's high-quality cast iron construction allows for extremely efficient and – crucially – long-lasting heat release, even after the fire has been completely extinguished. The K12 guarantees thermal comfort and economical fuel use. The technical solutions used, including the exhaust gas post-combustion system, increase the device's efficiency and make heating more environmentally friendly.

Solid construction and precise control

The K12 model was designed with a focus on durability and functionality. Massive cast iron walls guarantee stability and resistance to high temperatures for many years. The stove also offers convenient and practical control over the combustion process thanks to a system of two independent regulators.

Ecology for the environment

The K12 stove has been designed to meet Ecodesign standards and other strict environmental requirements of regional regulations regarding emission standards for fireplaces and other solid fuel heating appliances, including: BImSchV 2. It has also been tested to the new, more stringent EN 16510 standard.

This guarantees clean combustion and high energy efficiency for the environment. It can operate in homes with heat recovery, making it an excellent solution for modern buildings. It is a reliable heat source that combines safety, durability, and environmental friendliness.
