Introducing the Stûv 21‑105, a premium single-face built‑in fireplace with a vertically sliding, frameless guillotine glass door. Slide up for open‑fire ambiance, or close down for radiant heating and clean efficiency. Only a slender steel frame surrounds the firebox—to maximize your view of the flames.
This model requires a recess of approximately (~1210 × 1425 × 613 mm), optimized for modern masonry or clad installations that showcase minimal framing.
Rear-retracting frameless glass: Maximizes flame exposure for either full fire or controlled heat mode.
High-performance warmth: Abundant firebox capacity with powerful heat output for mid‑large spaces.
Effortless maintenance: Tilt-out cleaning door, user-friendly service access, and modular filters.
Architectural integration: Choose from minimalist or statement frames, with options for fully built-in or visibly finished installations.
Nominal heat output: (~19 kW), heating up to (~130 m²).
Efficiency: About 77% with closed glass or partially raised configuration.
Firebox capacity: ~, handling logs up to 32″ (≈80 cm).
Retractable guillotine door: Lifts into the recess behind the surround, then tilts forward for simple glass and seal maintenance.
Natural convection system: Combines two lower room air intakes and two upper heat outlets to temper the firebox and warm the room evenly—no fan required.
Accessible mechanics: Invisible slide rails and pulley cables sit hidden yet remain serviceable without disassembling finishes.
Multiple frame options: From minimalist steel frames (SF5/SF6 style) to recessed hemlock finishes—available in StûvGrey or rust tones, depth-adjustable for flush finish.
Outside air connection: Optional airtight combustion air intake (Ø 150 mm / 6″) keeps indoor air clean and supports high-performance sealed-home setups.
Optional accessories: Guillotine spark screen, linear convection grilles, integrated front panels, and adjustable stands available.
