The Stûv 21/85 SF Single Faced Inset Wood Burning Stove is a mid-size single-sided retractable fireplace designed to combine architectural integration, broad flame visibility and strong wood burning performance. It sits between the more compact 75 model and the wider 95 and 105 versions, making it a versatile choice for a wide range of interiors.
Like the rest of the Stûv 21 family, it works in two distinct ways. With the glass raised, it offers the atmosphere of an open fire. With the glass lowered, it becomes a sealed, high-efficiency stove with better safety, controlled combustion and reduced heat loss. The wide glazed opening gives a generous view of the flames, while the pivoting door makes it easier to clean the glass and access the mechanical parts. The mechanism itself remains hidden, preserving the clean minimalist appearance of the opening.
The 21/85 SF is often a useful balance point in the single-sided range because it gives a noticeably broader fire than the 75 without stepping into the larger visual scale of the 95, 105 or 125 models. In performance terms, it offers a rated output of 16.1 kW, an optimal range of 7.6 to 20.7 kW, 77.8% efficiency at rated power and an energy efficiency class of A. It accepts 60 cm logs, weighs 234 kg, and uses a 200 mm flue outlet. It also supports outside air connection, optional barbecue use and a wide selection of Stûv claddings, frames and ready-to-fit fireplace options.

Expert Insight
The 21/85 SF is one of the more adaptable models in the Stûv 21 range because it offers a stronger visual presence than the 75 without becoming overly demanding in terms of width and scale. That often makes it a sensible choice for customers who want a meaningful architectural fire but do not need the wider firebox formats.
It also benefits from the option of either partial raising or total raising of the glass depending on installation approach, which can be useful where height limitations affect the final design.
Suitability
The Stûv 21/85 SF Single Faced Inset Wood Burning Stove is well suited to modern living rooms, feature chimney breasts and interiors where a medium-width retractable built-in wood fire is wanted with strong performance and flexible styling options.
