Kalfire W100/61F Wood Fireplace — Large Front Wood Fire with High Heat Output
The Kalfire W100/61F Wood Fireplace delivers a powerful front-facing fire experience with a wide flame view and strong heat output. Designed by Kalfire, it combines efficient combustion with a clean architectural design, so it fits naturally into modern wall units and mantelpiece installations.
Because of its larger format, this model suits bigger living spaces where both performance and visual impact matter. In addition, it maintains high efficiency while delivering a bold wood fire atmosphere.
Kalfire W100/61F Wood Fireplace front glass design
The Kalfire W100/61F Wood Fireplace uses a single front glass panel, so the flames remain fully visible from the main viewing direction. As a result, the fire becomes the dominant visual feature in the room.
Moreover, the wide glass surface enhances flame depth and movement. Therefore, the fireplace creates a stronger and more immersive fire experience. In fact, it also works well as a central feature in larger interiors.
Interior options for Kalfire W100/61F Wood Fireplace
The interior plays an important role in both appearance and heat behavior, even when the fireplace is not in use. For this reason, Kalfire offers multiple interior finishes.
You can choose skamol for a traditional heat-resistant structure, while lamellas add a more textured visual effect. In addition, a design interior creates a more modern and refined finish. Consequently, the fireplace can be matched to a wide range of interior styles. Furthermore, each option subtly changes the visual depth of the flame.
Mounting trims for flexible installation depth
Mounting trims allow flexible adjustment of installation depth, so the fireplace integrates neatly into different wall constructions. For this model, options include 2.5 cm, 7 cm, and 10 cm depths with 4 mm or 8 mm thicknesses.
Moreover, this flexibility supports precise architectural integration. Therefore, installers can achieve a clean and tailored built-in appearance. In turn, this improves both design accuracy and installation versatility.
