Come home, bring in the wood, light it, put your feet up and unwind. Campfire feeling all year round. An open fireplace is the oldest form of fire. You’re right up close – with no glass in between.
An Urfeuer fireplace satisfies the deep human longing for safety and comfort. Sitting by the fire, dreaming, relaxing, feeling good. The heat output is secondary – it’s all about the feeling. The faster life gets, the more popular open fireplaces become.
However, open fireplaces draw a lot of air from the room (300 to 400 cubic meters per hour). Older buildings allow enough air to flow back in through small gaps and cracks in windows and doors.

In well-insulated or airtight houses, this can become a problem. The air in the room decreases, creating negative pressure that can draw smoke back into the living space. To prevent this, BRUNNER developed a sophisticated solution: Urfeuer fireplaces control the pressure balance through a dedicated air supply and exhaust system with an external air connection.
No smoke, no lack of air
Open fireplaces draw a lot of air from the room (300 to 400 cubic meters per hour). Older buildings allow enough air to flow back in through small gaps and cracks in windows and doors. In airtight or well-insulated houses, however, this can become an issue. The air in the room decreases, creating negative pressure that can cause smoke to enter the living space.
To prevent this, BRUNNER developed a sophisticated solution: Urfeuer fireplaces regulate pressure balance through a dedicated supply and exhaust air system with an external air connection.

To prevent exactly that, BRUNNER developed a sophisticated system: Urfeuer fireplaces regulate pressure balance through a controlled supply and exhaust air system with an external air connection. This ensures the fire is always supplied with enough fresh air, directed precisely to the fireplace. As a result, there are no unwanted drafts.
Invisible safety
As inviting and captivating as an open fire may be, caution is needed with sparking softwood or falling embers. The fire should never be left unattended during burning. Since that’s not always easy to manage, BRUNNER has a clever solution. A key safety feature, included as standard in all Urfeuer fireplaces, is the spark guard. It’s made of black-painted stainless steel mesh that slides up and down smoothly.
When retracted, it disappears completely – hidden in a narrow gap between the fire protection panels – and when lowered, it remains almost invisible. The eye doesn’t notice it during operation, so it never distracts from the fire itself.

A special cooking experience
Urfeuer fireplaces come in different models – wall-mounted, freestanding or built into the kitchen. For those who love to grill, that’s something you want to enjoy all year round, no matter the weather. A roast that cooks slowly and gently over an open fire is simply something special – just like grilled fish or vegetables.
The kitchen is also a place where everyone loves to gather – family and friends alike. It’s where people cook, talk and spend time together.

What could be better than a BRUNNER kitchen fireplace that also brings a touch of warmth and comfort to the room? It can be integrated into the design of a new kitchen and built in at countertop height.
A rotisserie with a sturdy gear motor is perfectly positioned in front of the firebox wall of the open kitchen fireplace. Roasts, legs of meat or roast beef cook slowly and evenly – and always turn out perfectly. Alternatively, a grill rack can be placed directly over the embers for classic flame-grilled dishes.
Conclusion
With an open fireplace, you bring the most original form of fire into your home. It appeals to all the senses – you can see the flames, smell the wood, hear the crackling and feel the warmth. You can lean back, watch the dance of the fire and breathe easy thanks to the BRUNNER air supply and exhaust system. The invisible spark guard keeps both embers and sparks safely in check. The kitchen fireplace makes every cooking enthusiast’s heart beat faster – and a grilled, juicy steak prepared in a kitchen fireplace is simply unmatched in taste.
Expert advice
The open fireplace is something truly special in many ways. It’s not just the unique atmosphere an Urfeuer creates – the option to grill and roast over an open flame is the icing on the cake for any passionate home cook.
