Living and the heat demand of homes have changed over the decades. We pay attention to the stylish design and convenient use of fireplaces. We work in close co-operation with experts in design, construction and energy technology.
In total, we have been granted close to 60 registered patents and registered over 100 protected designs. All our fireplaces include protected innovations – inventions that make your NunnaUuni unique.
The success of NunnaUuni is based on the uniquely durable Mammutti soapstone type, our own innovations that promote efficient burning and fast heat storage, continuous product development, and a design and product range that have significance to the customers.
The Golden Fire gasification burning method produces pure and superior heat effect. Unlike cast fireplace materials in ceramics, the uniform, oriented and natural Mammutti type of soapstone conducts heat rapidly into the structures of the fireplace. This ensures that heat is captured and stored efficiently. You can burn wood rapidly at a high temperature […]
NunnaUuni’s patented Golden Fire wood burning method (Pat. no. EP1008808) produces an extremely high temperature, in which wood gasifies evenly and burns efficiently. As a result, NunnaUuni fireplaces produce only minimal wood-burning emissions. Genuine NunnaUuni fireplaces, tested in accordance with heat storing fireplace test method, are built to adhere the emission limits of the future […]
Soapstone is a natural material with many different types as regards composition and structure. They all share one thing in common, which is their high content in talc, which makes them a soft natural stone. The Mammutti soapstone types of NunnaUuni’s own deposit are primarily made of half talc and half magnesite. Talc has become […]
The Mammutti soapstone injector unit (Patent no. 122079) rapidly recovers the great heat generated by burning through its four channels, thanks to the great thermal conductivity of the Mammutti type of soapstone. This heats the injector unit, which stores an exceptional amount of heat in regard to its mass. As the injector unit recovers the […]
NunnaUuni-Aqua+ can be used as part of your home’s hydronic heating system or just for heating domestic water. Only some of the heat produced by the fireplace is used for hot water, while the rest radiates slowly and evenly into your home. The heat exchanger is at the core of the fireplace Does not affect […]
Carefully selected Mammutti soapstone conducts heat quickly in the direction of the talc foliation and more slowly against the foliation. DEKO Due‘s double shell structure takes advantage of this relationship between thermal conductivity and the direction of foliation. The double shell structure evens out the intense heat of the stove, contrary to a soapstone […]
