Kit system fireplace

The modern solution with a system

Attractive thermal concrete in system construction

The BRUNNER BSK kit system fireplace can be assembled relatively quickly thanks to the dimensionally accurate moulded parts made of thermal concrete. It could hardly be simpler and more economical, without you having to forego individual design options. Because even a kit system fireplace can be customised: the fireplace cover can be extended or the thermal concrete can simply be filled or painted. Be creative.

The metal fireplace insert of the BRUNNER system fireplace has a steel or cast-iron hood, depending on the version.
The large glass formats and the modern cladding made of thermal concrete are particularly attractive.
Quick-reaction furnace
The heating fireplace with steel hood offers a fast and high hot air output, but cools down quickly after burn-off.

For priority fire atmosphere with warmth

A system fireplace is installed when primarily atmosphere is desired. Construction, fuel quantity and the associated heat output are adapted to this.

Kit system fireplaces are also called "quick- reaction furnaces" because of their heat output. The heat release takes place during the burn-off. The heating effect results from the radiation of the combustion chamber through the large viewing glass and the hot air.

Wood fire as a kit system solution

BRUNNER quality with a customised fireplace cover

There is no easier or cheaper way to build a fireplace or stove. Dimensionally accurate moulded parts made of thermal concrete enable quick assembly. Components and shape are designed in such a way that the fireplace system can be created with minimal space requirements, taking into account function and safety. Only components of handcrafted stove construction are used, which are offered to the specialist company as a finished kit. An original BRUNNER heating insert is installed in all versions. The same product that has also established itself in artisan stove construction.

The design of the cladding is possible in different quality levels:

  • In the practical version with thermal concrete shell, untreated and deliberately left in exposed concrete as an architecture element.
  • Or a hand-finished surface, which is painted, plastered and covered with ceramic elements.

Furthermore, the cladding elements can be extended in height. Room-high versions have thermal insulation to the room ceiling and on-site warm air outlets. If the system cladding is structurally extended, all ideas and concepts can be realised with BRUNNER fireplace panels. The distance to the wall can be minimised with heat protection plates (accessories) mounted on the fireplace insert.

Heating fireplace with cast iron hood

During combustion, heat is extracted from the heating gases across the metallic surfaces and the integrated hot air exchanger. The fireplace insert becomes hot. The room air flowing into the fireplace cover via the lower openings is heated on the hot surfaces and released into the room as warm air. Of course, the fireplace cover is also heated from the inside via heat radiation. The combustion air can be supplied from the outside via a duct. The combustion air duct prevents the air from entering the combustion chamber by forming a protective screen in front of the viewing glass, which reduces soot and dust particle contamination.

Easy to operate

Simple and uncomplicated

Manually operated or automated

The combustion air can be controlled manually with just one operating element (lever). Effortless and easy to understand. The symbols on the glass provide additional support.

Of course, the white display (EAS) shows that it can also be operated automatically. The most convenient version is the combination with an electronic combustion control (EAS). All you have to do is light the stove or add fuel, the control system takes care of everything else. High efficiency is the result, because the EAS servomotor never forgets to readjust and always stops the combustion air supply at the end of the burn-off. This is particularly convenient if the stove cannot be operated any further after its kindling, either because you go to bed or you leave the house.

Thermal concrete look

Modern fireplace cover

Puristic, stylish and elegant - the fireplace body in its simplest form and appearance. Precisely fitting thermal concrete elements, poured and assembled with shadow gap. Here, perfection lies in the imperfect. The concrete surface has edges and irregularities, which is precisely why it looks so clear and unobtrusive. It is highly advisable to seal the thermal concrete elements with carnauba wax after assembly. This is absolutely recommended to avoid unwanted stains permanently. Because once a hand or shoulder with natural skin grease has leaned against the cold fireplace cover, the dark stain is almost impossible to get rid of. Other liquids are also absorbed by the concrete surface and permanently change its appearance.

BRUNNER has three top priorities: quality, a love of individual craftsmanship and practicality. System fireplaces combine these three categories in a compact, practical and high-quality package. Inside, a BRUNNER kit system fireplace (BSK) is a genuine BRUNNER fireplace, in the usual excellent quality. But here the stove cover is not individually built by the stove fitter, but is industrially prefabricated.

While a hand-built system creates plenty of room for individuality, you are much more limited with a kit system fireplace. But on the other hand, a kit system fireplace is much easier to assemble and place in the living space. The craftsman simply assembles the supplied modules and the system fireplace is ready. It delivers the same quality as its counterpart from individual fireplace construction. This saves time and money. But the best thing is that you can still fulfil your own wishes in terms of design and implementation. Because BRUNNER kit system fireplaces can be plastered, filled or painted in countless ways. Even metal covers are possible. This makes a BRUNNER system fireplace a genuine alternative, inexpensive and acknowledged high-quality option.

A fireplace or stove is a thermo-physical, interior design element. This means that it must meet not only visual but also technical requirements. Just like central heating, proper installation is important for proper operation. But don't worry: the installation of a BSK is so practical and simple that it can sometimes be completed in just a few hours.

There are currently 11 different versions of the BSK, which often differ in their glass format. BRUNNER Kit system fireplaces are available in corner format, as a tunnel, as a panorama or as a classic flat version. In some cases, you can also choose between left and right versions, as well as between revolving and sliding door. A special highlight are the formats that are also available as water-bearing versions. This means that it is not only possible to install a real BRUNNER fireplace in your home in the simplest way, cheaply and quickly. You can also generate hot water at the same time and save money.

The core of a device, a heater or a car, is always the most essential. Whether a computer chip, a boiler or an engine, the ultimate quality of a technical product always goes back to its core. And that is precisely why the Kit System fireplace BSK from BRUNNER is so popular: although its stove cover is prefabricated, made of high-quality thermal concrete, its core is a genuine BRUNNER fireplace insert. And like each of its siblings, this one is the result of decades of experience and a willingness to innovate. The need to make everything that is good simply even better and to question everything in the process is part of our culture. The icing on the cake is that every one of our customers, whether tradesmen or end customers, gets a real contact person quickly and easily if they have questions or problems.

We heat the first winter with a stove installed by stove builder Stefan Hock from Bessenbach. Not only does the stove look great and fit perfectly into the picture, it also makes you really warm, and with far less wood than we needed before.

Better some euros more for the brand quality of BRUNNER
Ralf Lenz: Dear Ladies and Gentlemen, The chimney sweep just came. He wouldn’t believe that we had left our stove burning all winter. It turns out that it's better to spend a few euros more on brand quality such as a Brunner stove than to buy cheap junk. It pays off in the long run - and the environment is happy too :-) Cordia...
