Why choose a modern Nobis wood-burning stove?
A wood-burning stove is an efficient source of heat that you can use at any time. Whether during transitional seasons, for leisure, or when the power is out. The Nobis Classic wood-burning stove on legs features a very large firebox that easily accommodates logs up to 50 cm long. This alone makes it just as effective for heating as typical fireplace inserts. An undeniable advantage is the minimal space required to install the wood-burning stove.
The large, modern firebox window showcases a stunning fire, thanks to the high wood combustion efficiency of 86%. The minimalist door handle and simple form are hallmarks of Italian design.

Technologies used:
Sealed firebox design
The firebox body has been designed so that the stove can operate in buildings equipped with mechanical ventilation (heat recovery). When outside air is connected directly to the combustion chamber, even in buildings with natural ventilation, residents will not feel a lack of air in the living room.
Grate-less firebox
The firebox is lined with fireclay, which provides a beautiful view of the fire and improves wood combustion efficiency. Wood is burned using the ash-bed method, which means that even when burning large amounts of wood, frequent cleaning is not necessary. Air supplied “from above” allows the wood to burn longer and provides more efficient heating. Additionally, the firebox door is equipped with a clean-glass system featuring upper and lower air curtains. This design ensures that the glass remains clear even after prolonged use.
Precise Fire Control
The combustion process in the stove is controlled by a single slider, which precisely regulates the flow of air into the firebox. Fully opening the primary air intake helps get the fire started in the fireplace by generating additional draft in the chimney. Secondary air and exhaust gas afterburning, on the other hand, are essential to ensure that the wood burns completely.
