Bullerjan Free Flow - The classic among wood-burning stoves

40 years ago, Eric Darnell revolutionised heating with wood with the invention of the Free Flow. Thanks to his innovative technology, rooms that were previously considered unheatable can now be heated quickly and evenly. The unmistakable shape of the Free Flow is a prime example of well thought-out and functional design. These features make it one of the best known and most recognised stoves in the world. With the introduction of smaller models, thousands of households of different sizes now benefit from the exceptional heating properties of the Free Flow.

Storage ceramics

Alongside steel and cast iron, ceramic is a classic stove material that is characterised by its heat resistance and excellent storage properties. In terms of design, ceramic offers a wide range of possibilities for individual shapes and colours. This natural material is characterised by its homely appearance, durability and ease of care.

Why ceramic?

Ceramic is one of the most classic materials for wood-burning stoves, alongside steel and cast iron. This is due to its outstanding heat resistance and excellent storage properties. In terms of design, ceramic offers a wide range of possibilities in terms of shape and colour, making it an attractive choice for individually designed stoves. In addition, this natural and sustainable material radiates a particularly pleasant and cosy atmosphere and impresses with its durability and ease of maintenance.

Surfaces and colours

In addition to the glazes selected exclusively for Bullerjan by designer Sebastian Herkner, we offer a wide range of additional surface options. With sufficient lead time, we can even realise individual desired colours.

Processing quality

The B4 & B4 S impresses with its exceptional robustness, which is based on the use of above-average strength steel for the body. In addition, the wearing parts that are particularly exposed to fire can be replaced at any time and can be renewed even after many years.

RLU/DIBt-compliant

With a tested nominal heat output of 5 kilowatts, the B4 S can be used in almost all room situations. It can optionally be operated independently of the ambient air (RLU) in accordance with the requirements of the German Institute for Building Technology (DIBt) and is therefore ideal for use in low-energy and passive houses with a controlled ventilation system.

Which wood-burning stove is right for your room?

DChoosing the right wood-burning stove depends largely on the appropriate heat output. This is determined by the nominal heat output in kilowatts (kW), which is a calculated average value of the heat output per burn.

A general guide value for the selection is

1 kW nominal heat output is sufficient for rooms of around 8 to 15 m² with a ceiling height of 2.5 metres. This value can vary depending on the installation site, geographical location, room characteristics and chimney type. The room volume and the degree of insulation (floor, walls, windows, roof) also play a decisive role in determining the required output.

For a precise determination of the required heating output in your specific room situation, we recommend consulting your Bullerjan specialist dealer and your chimney sweep.
