In a heat-storing NunnaUuni fireplace, the atmosphere of the Golden Fire continues as pleasantly soft radiant heat long after the flames have gone out. An enjoyable warmth and the clean burning of the Golden Fire method are guaranteed by the heat resistance, good heat storage capacity and excellent thermal conductivity of the Mammutti soapstone. The material of the NunnaUuni fireplaces is Mammutti soapstone from the fire chamber to the surface.
Mammutti soapstone transfers heat quickly into the internal structures of the fireplace, unlike bricks or cast elements, which are classified by their thermal characteristics as insulators. Quick heat storage shortens the heating time of the fireplace and reduces the amount of wood needed for burning.
Fine-grained Mammutti soapstone withstands intense heat, which means it can be used in the fire chamber. The excellent heat storage capacity of the fire chamber increases the amount of heat stored in the fireplace, so a great amount of heat can be stored even in a smaller size.
The great amount of heat stored in the NunnaUuni spreads out evenly on the entire exterior surface. It is slowly released as steady radiant heat and emits an enjoyable warmth.
Fireproof Mammutti soapstone makes it possible to utilise the patented Golden Fire gasification burning method in NunnaUuni fireplaces. The hot and efficient burning of the Golden Fire ensures clean flue gases with abundant flames.
