B⁴ Steel, Keramik und Keramik+

Design: Sebastian Herkner

Our latest B⁴ fireplace was designed by Sebastian Herkner, just like the B3 model. The B⁴ has a spacious combustion chamber with a large viewing panel, which gives you an unobstructed view of the beautifully calm burning fire. The B⁴ can be used in virtually any room thanks to its wide power range (6 kW, 8 kW and 10 kW). Intuitive control and an extremely high build quality are a given with any Bullerjan product.

The B⁴ is available in three basic versions differing in look and function. Moreover, you have a wide range of interesting ways in which to adapt your B⁴ to your interior design.
