Description
Classic cast iron in a modern, eco-friendly version
KOZA K6 ECO is a cast iron wood stove that combines timeless style, durability, and modern ecological solutions. Designed for homes that need both an effective heat source and an elegant interior design element. It heats areas from 50 m² to 110 m², ensuring a cozy atmosphere and thermal comfort in your home.
Durability and reliability
The K6 ECO STOVE has been designed to meet the strict environmental requirements of regional regulations regarding emission standards for fireplaces and other solid fuel heating appliances, including Ecodesign, BImSchV 2, and Flamme Verte.
This guarantees clean combustion, high energy efficiency, and environmental friendliness. Thanks to the outside air intake, the stove can be easily connected to heat recovery systems, making it an excellent solution for modern, energy-efficient buildings. Solid cast iron and precise technical solutions make the K6 ECO STOVE an investment that will last for years.
Vermiculite lining - what do you need to know about it?
Lining the combustion chamber with vermiculite significantly increases the comfort and efficiency of the stove. Thanks to its excellent insulating properties, this material retains heat inside the combustion chamber, which translates into a higher combustion temperature, cleaner soot combustion, and longer-lasting glass transparency. Vermiculite is an insulator - it doesn't heat up as much as, for example, TERMOTEC, making it an excellent thermal insulator. Furthermore, it's safe in contact with fire - it doesn't emit toxic gases and doesn't burn. Thanks to these properties, the stove reaches optimal operating conditions faster. Additionally, its light, natural color highlights the aesthetics of a burning fire, creating an even more pleasant atmosphere in the home.
Why choose the K6 ECO STOVE?
- 8 mm cast iron walls - durability, high temperature resistance, and long-term trouble-free operation.
- Heating from 50 to 110 m² - the perfect choice for medium-sized rooms.
- Vermiculite lining - higher combustion temperature, cleaner glass, better efficiency, and lower fuel consumption.
- Deflector system - extending the exhaust gas path for optimal energy use.
- Classic front equipped with Heat-resistant glazing that withstands temperatures up to 600°C.
- Cold handle system - convenient for everyday use (the handle can be removed to prevent it from heating up after the ignition process is complete).
- Drawer-style ash pan - quick and easy cleaning of the stove.
- Decorative fence - enhances aesthetics and prevents wood from falling out.
- Eco-friendly solution - meets EU and regional emission standards.
- Factory-installed air intake - ideal for homes with heat recovery.
- Adjustable exhaust outlet (at the back or top of the stove) allows for various installation conditions.
- Intuitive air supply regulation and combustion process control (regulators in the base; air enters through one channel under the ash pan and the other directly into the combustion chamber).
