The modern system solution in attractive heat-storing concrete
Thanks to its precisely fitting heat-storing concrete components, the BRUNNER system fireplace BSK can be assembled quickly and easily. It’s hard to imagine a simpler or more cost-effective installation without sacrificing individual design options. A system fireplace can also be customized – the casing can be extended, or the heat-storing concrete can simply be plastered or painted. Be creative.
The features
- 1. Quick-response stove
A system fireplace is installed when the primary goal is creating atmosphere. Heat is released during the burn phase, generated through radiant heat from the large viewing window and warm air circulation.
- 2. 90° bend
with cleaning opening
- 3. Distinctive appearance & fireplace casing
Particularly striking are the large glass formats and the modern cladding made of heat-storing concrete.
- 4. Throttle valve
integrated
- 5. Heat exchanger ring
Depending on the model, the metallic fireplace insert of the BRUNNER system fireplace features a steel or cast-iron hood. Inside, a cast-iron heat exchanger ring with a deflection plate is installed.
- 6. Heat protection plate
Allows for maintaining a minimal distance to the adjoining wall.
- 7. Combustion air
Combustion air can be supplied via an external air duct. The air guidance system is designed so that the incoming air flows along the inside of the viewing window, creating a protective air curtain that reduces soiling from soot and dust particles.
- 8. Glass panel
System fireplaces feature large glass panels to maximize the fire experience.
- 9. Operating convenience
There are two ways to control the combustion air: manually via a lever, or in combination with an electronic combustion control system (EAS). With the EAS, you only need to light or refuel the fire – the control unit takes care of everything else automatically.
The four
glass pane options
Corner system fireplaces
Corner fireplaces, with their two-sided glass design, offer a generous view of the fire and create an inviting atmosphere that visually opens up the space. Thanks to their slim corner configuration, they require minimal floor space while making optimal use of the room’s sense of openness.
Tunnel system fireplaces
BRUNNER’s tunnel-format system fireplaces feature glass panels on both sides, offering a captivating view of the fire from two directions. Ideal as an architectural highlight or room divider, they connect different living areas and create an open, harmonious atmosphere.
Flat system fireplaces
BRUNNER’s flat system fireplaces integrate perfectly into modern living concepts thanks to their minimalist design and low installation height. They provide an elegant view of the fire and create a cozy, tranquil atmosphere.
Panorama system fireplaces
The panorama system fireplace is always the centerpiece, offering a magnificent view of the fire. With its clearly defined geometric body, it becomes a true eye-catcher in any space. It integrates seamlessly into the living area and provides fire enjoyment from three sides. Also available in a vertical format, it offers maximum fire visibility on the smallest possible panoramic footprint.
Wood fire as a system solution
BRUNNER quality with a customizable fireplace casing
A fireplace or stove can hardly be built faster or more affordably. Precisely fitting heat-storing concrete components allow for quick installation. The parts and design are engineered so that the fireplace system can be built with minimal space requirements while ensuring full functionality and safety. Only components from traditional stove construction are used, offered as a complete kit for professional installation. Every version includes an original BRUNNER heating insert – the same proven product used in handcrafted stove building.
The system fireplace as a “quick-response stove”
System fireplaces are considered quick-response stoves because they provide immediately noticeable warmth during the burn phase. The heating effect is generated through radiant heat from the large viewing window as well as warm air produced by metallic surfaces and an integrated heat exchanger. Room air enters through lower openings, is heated by the hot surfaces, and then released back into the room as warm air. At the same time, the fireplace casing itself heats up. In certain models, a small additional storage module extends the heat output after the fire has burned down. The combustion air can be supplied from outside, and a special air guide keeps the viewing window clean and free from soot and dust.
Heat storage options
Warm-air system fireplace with cast-iron rings
The hot flue gases flow through metallic ring elements. Their ribbed structure and integrated deflection channels provide a large heat exchange surface. This solution is ideal when high warm-air output is required within a small footprint.
Storage system fireplace with ceramic storage rings
The hot flue gases flow through ceramic storage elements. The spiral-shaped design of the rings provides three flue gas channels. This solution is ideal when a storage fireplace with a tiled-stove heating effect is desired within the smallest possible footprint.
Water-bearing system fireplace with boiler module
A water-bearing design with an additional boiler module is also possible. In this setup, the still-hot flue gases from the firebox flow through a boiler body positioned directly above the combustion chamber. This allows the system to not only deliver the cozy fireplace effect but also support the home’s central heating system.
Heat-storing concrete look
Modern fireplace casing
Raw, authentic, and full of industrial charm: made from precisely cast heat-storing concrete elements, assembled with fine shadow joints, the fireplace casing impresses with its striking appearance.
Slight irregularities, pores, or edges are natural and even desired, as they emphasize the unique character of the material. While the shape of the casing cannot be altered, the surface can be customized with a glaze, paint, or plaster finish. You can find out more about these options here.

FAQ System fireplaces
- What are the advantages of a system fireplace compared to a custom-built installation?
While a handcrafted fireplace offers plenty of room for individuality, a system fireplace is more limited in that regard. However, it can be assembled and installed in the living space much more easily. The installer simply puts together the supplied modules, and the system fireplace is ready to use. It delivers the same quality as its custom-built counterpart while saving both time and money.
The best part is that you can still realize your personal design preferences. BRUNNER system fireplaces can be plastered, smoothed, or painted in countless ways. Even steel claddings are possible with selected models. This makes a BRUNNER system fireplace a true alternative – affordable, yet maintaining the same high level of quality.
- What is a system fireplace?
BRUNNER stands for three core values: quality, a passion for craftsmanship, and practical functionality. System fireplaces combine all three in one compact, practical, and high-quality package. Inside, a BRUNNER System Fireplace (BSK) is a genuine BRUNNER fireplace with the same outstanding quality you would expect. However, the outer casing is not individually built by a stove fitter but is made from prefabricated heat-storing concrete elements.
- What does “green” mean for system fireplaces?
The “green” series (e.g. BSK 42-42) includes the new BKH green insert with patented trough combustion, an optional retrofit catalyst and burn control. It falls well below current emission limits – not only in the lab, but also in everyday home operation.
- Can I install a system unit myself?
No – although system fireplaces are designed as kits, they may only be installed by a qualified specialist company. The precisely fitting concrete elements must be assembled professionally, connected to the chimney and operated safely.
- What is the difference between system fireplaces and fireplace inserts?
A system fireplace is a modular fireplace kit with custom-made heat-concrete elements, combined with a fireplace insert. It can be assembled within a few hours, offers large glass fronts, quick heat output and flexible surface design. A fireplace insert, by contrast, is supplied without the finished concrete casing. In other words: system fireplace = insert + cladding/kit, insert = only the inner part.
