Choose responsibly for a wood fireplace
Our state-of-the-art technology has dramatically improved the efficiency of wood fires, especially compared to that of a traditional open fireplace. In a closed hearth, the fire is sealed behind a glass panel. This is not only safer, but also has the advantage of retaining heat and releasing it in a controlled way to the surroundings. Yet the Kalfire W doesn’t sacrifice the sensory pleasure and sociability of the experience of an open fire. frameless glass panel allows for a full, unobstructed view of the play of flames.
The Kalfire W operates independently of the space where it is installed – when it is closed, it does not draw in air from the room. The fire draws in fresh air (often cold) from outside and then discharges the smoke through the chimney flue. The built-in valve system ensures that exclusively cold air from the exterior is used for combustion.
When you open the sliding glass door of the hearth to add wood to the fire, the Kalfire W activates different air flows. The combustion air that the fire draws in directly from the room is compensated by a built-in two-way valve system. The cold air from outside is sent along several integrated heat exchangers and is heated in the convection casing before entering the room. In this way, the Kalfire W not only prevents cold drafts and avoids the release of smoke into the room, but also ensures that air pressure is always in balance.
