The Stûv 22/110 DF Double Sided Inset Wood Burning Fire is a large double-sided built-in fireplace designed to make the fire visible through two opposing glass faces, allowing it to act as both a high-performance heat source and a transparent architectural divider between spaces. It is the largest double-sided model in the Stûv 22 range, combining substantial output with retractable glass on both sides.
What defines this model is the way it balances openness with control. In closed-fire mode, the glass remains lowered and the appliance delivers strong heat output while preserving a clear view of the flames from both sides. In open-fire mode, the retractable glass allows a more direct experience of the fire. The product data also states that the unit uses external air and compensation air systems so that open-fire use does not pull warm room air out of the interior or upset internal ventilation balance in the same way as a conventional open fireplace. Because both sides are glazed, the fire can be enjoyed in transparency between two adjoining areas, making it especially effective as a dividing feature without visually closing off the space.
The technical design is built around high-output performance and airtight combustion. The Stûv 22/110 DF delivers a 20 kW nominal output, with a usage range of 8 to 23 kW, 77% efficiency and an energy efficiency class of A. It accepts 80 cm horizontal logs, uses a 250 mm smoke flue, and supports direct external air inlet, compensation air, primary and secondary air control, post-combustion and high airtightness. The door also swings forward to make cleaning the inner face of the glass easier, which is especially useful on a double-sided appliance where visibility from both rooms matters. Optional additions include a barbecue kit, façade, log rack, front insulation kit and multiple ready-to-fit fireplace and frame solutions, including the D4 frame shown in the supplied example.

Expert Insight
The most important difference with the 22/110 DF is that it is not simply a wide fireplace with glass on two sides. Because it is engineered as a double-sided retractable appliance, it can divide two spaces while maintaining visual connection through the fire. That makes it far more architectural than a standard front-facing inset and especially effective in open-plan layouts where zoning is needed without blocking light or sightlines.
The forward-swinging door is also a meaningful practical detail. On a double-sided fireplace, keeping both inner glass faces clean matters more, and access for maintenance becomes more important than on a single-sided unit. Combined with the external and compensation air design, this is a technically resolved fireplace rather than a simple decorative see-through fire.
Suitability
The Stûv 22/110 DF Double Sided Inset Wood Burning Fire is well suited to open-plan interiors, room-dividing fireplace projects, large architectural renovations and homes where the fireplace needs to connect two spaces while providing major visual and heat impact. It is a strong choice for customers who want the widest Stûv 22 double-sided fire with retractable glass and substantial output.
Installation / Technical Notes
