High insulation performance that ensures safety Double chimneys mainly feature a metal seal that encloses the insulation material, which connects the internal and external chimneys with metal, creating a "heat bridge" that allows heat to escape from the chimney interior, thus reducing insulation effectiveness. DINAK's chimneys connect the insulation materials, forming a single unit inside the chimney, preventing internal heat from escaping. Top-level corrosion resistance rated V3 DINAK is the only brand in Japan that uses 0.6mm SUS316L, which has excellent corrosion resistance, among chimneys sold domestically. It has obtained the highest rank "V3" in the corrosion resistance classification of metal chimneys under the European "CE mark," which is the most stringent safety standard for industrial products in the world. (Many double chimneys for wood stoves are rated "V2.")

Compliant with European standard EN13240. This product has passed combustion tests in Europe, the home of wood stoves. Cast iron wood stoves have a high far-infrared effect due to radiant heat, making them retain warmth for a long time once heated, warming you from the core of your body. The combustion method employs secondary combustion, which burns the impurities generated by burning wood again, reducing wood consumption and soot in the chimney, resulting in clean exhaust. The flickering of the wood stove's flames has a unique fluctuation known as "1/f fluctuation," similar to the twinkling of stars, the movement of the wind, and the murmuring of clear streams, and this fluctuation provides us with healing. The soothing effect of the flames is truly captivating.
