Description
KOZA K9 ECO - choose cast iron durability in an eco-friendly version
KOZA K9 ECO is a classic cast iron wood stove with a modern twist. It combines timeless aesthetics with eco-friendly solutions and exceptional efficiency. Thanks to its solid construction (165 kg, 8 mm thick cast iron walls) and a vermiculite-lined combustion chamber, the device ensures rapid heating, a cleaner glass, and better combustion of exhaust gases. This reliable heat source will heat areas from 85 m² to 125 m² and is ideal for both private homes and commercial spaces.
Durability and Reliability
The K9 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 its external 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 a three-deflector system ensure this device will provide reliable service for many 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 firebox, 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 K9 ECO STOVE?
- K9 ECO cast iron wood stove - heats from 85 m² to 125 m².

I recommend products from kratki company. They are very good quality and what proud to say from Poland. I once had contact with the company and it was great. They do not oil the customer served me and without any resistance replaced the worn out component under warranty. Keep it up. I have a Blanka 12kW fireplace and a K-10 stove and I am mega satisfied. For the home I recommend to everyone a minimum of K-10 for me stove or if you prefer a goat plus pipes. As it will be "cooking" in the world I will have something to cook papu on and the heat will be there. A "must have" product worth every penny. Bravo team grids bravo Mr. Mark!!! I wish the people of kratki all the best and only successful products.
P.S..
Maybe someday there will be some kind of stove with an oven so that bread can be baked.
I sincerely greet you,
Jacek from PiasecznoThe content of the review was translated automatically. Show original contentPolecam produkty z firmy kratki. Są bardzo dobrej jakości i co dumnie można powiedzieć, że z Polski. Kiedyś miałem kontakt z firmą i było super. Nie olewają klienta obsłużyli mnie i bez żadnego oporu wymienili zużyty element na gwarancji. Tak trzymać. Mam kominek Blanka 12kW i piec K-10 i jestem mega zadowolony. Do domu polecam każdemu minimum K-10 dla mnie pieco-kuchnię albo jak kto woli kozę plus fajerki. Jak będzie "gotowało się" na świecie to będę miał na czym papu ugotować i ciepło będzie. Produkt "must have" wart każdej złotówki. Brawo team kratki brawo Panie Marku!!! Życzę ludziom z kratek wszystkiego dobrego i samych udanych produktów. P.S. Moźe kiedyś będzie jakaś pieco-kuchnia z piekarnikiem żeby chlebek można było upiec. Serdecznie pozdrawiam, Jacek z Piaseczna
