Kalfire W85/40F Wood Fireplace
The Kalfire W85/40F is a high-output front-facing wood fireplace designed to combine strong heating performance with a clean and modern built-in appearance. With a focused flame view and carefully engineered combustion system, this model delivers the atmosphere of a traditional wood fire while fitting naturally into contemporary living spaces.
Its balanced proportions make it suitable for wall units, fireplace surrounds, and bespoke cabinetry installations. The design creates a clear focal point within the room while providing the heat output needed for comfortable everyday use.
The result is a fireplace that combines visual impact with practical performance, making it well suited to homeowners looking for both style and efficiency.
Wide Front Glass Design
One of the key features of the Kalfire W85/40F is its large front-facing glass panel. The design provides a clean and uninterrupted view of the flames, allowing the fire to become a natural centrepiece within the room.
The focused flame picture enhances the atmosphere of the space and adds depth within the firebox. Whether installed within a modern feature wall or a more traditional fireplace setting, the front glass design creates a refined and balanced appearance.
Because the flames remain fully visible from the primary seating position, this model works particularly well in living areas where the fire is intended to be enjoyed as a main visual feature.
Interior Options
The interior finish contributes significantly to the overall appearance of the fireplace, even when the fire is not burning. Kalfire offers several options that allow the fireplace to suit different interior styles and design preferences.
Skamol provides a traditional fire-resistant finish with a lighter internal appearance. Lamellas introduce added structure and texture, creating a stronger visual effect inside the firebox. For more contemporary projects, the design interior offers a cleaner and more refined finish.
Each option slightly changes the overall character of the fireplace, allowing homeowners and designers to create a look that complements the surrounding space.
Flexible Installation Options
The Kalfire W85/40F is designed with installation flexibility in mind, making it easier to achieve a tailored built-in appearance across different projects.
Mounting trim options are available in 2.5 cm, 7 cm, and 10 cm depths with thickness choices of 4 mm or 8 mm. These options help installers align the fireplace accurately within different wall constructions and finishing materials.
This flexibility supports seamless integration into feature walls, custom cabinetry, and larger architectural installations while maintaining a clean and professional finish.
If you would like additional guidance on a professional stove installation or the wider wood-burning stove installation process, proper planning can help ensure the fireplace performs exactly as intended.

With an output of 14.8 kW, an efficiency rating of 81%, and an A+ energy label, this fireplace is well suited to medium and larger living spaces where consistent heat delivery is important. The combustion system is designed to maintain stable performance while supporting controlled fuel use.
