The Jøtul F 370 Advance is a series of wood stoves in cast iron. It differs from steel stoves by using the casting process to create double curved surfaces. It offers a grand view to the fire and rotates to display the fire from all corners of a room. As the first stove in the world, the interior of the burn chamber is white vermiculite. The Norwegian Tech. University has cooperated on the usability of the single air valve and we have succeeded in reducing particle emissions by 30% in daily operation. Soapstone or heat accumulating stones can be added to even out heat curves and radiate heat long after the fire has died out.
