The Stûv 22/70 Single-Faced Wood Burning Fireplace is the most compact one-sided model in the Stûv 22 range, designed to combine a clean architectural flame view with strong built-in heating performance. With its almost invisible frame, retractable glass and wide operating range, it is made for projects where the fire should feel fully integrated into the wall rather than framed as a conventional fireplace insert.

A defining feature of the Stûv 22 range is the retractable glass. In closed mode, the appliance delivers efficient, controlled heating with an uninterrupted view of the flames. In open-fire mode, the glass slides away to create a more direct fireside experience, while the system is designed so that external air is brought to the stove opening rather than pulling warm room air out of the space. That is a major technical advantage over a traditional open fireplace. The hidden integrated door frame also helps the visible finish material come as close as possible to the fire, which is central to the Stûv 22 concept.

This 70 model is the narrowest of the three one-sided widths, making it the easiest to integrate where the opening is more limited but a premium built-in fire is still required. It offers a 12.3 kW nominal output, an operating range of 6.9 to 16.5 kW, nominal efficiency of 80.6% and an energy efficiency class of A. It accepts horizontal logs in 55 or 33 cm lengths, uses a 180 mm flue outlet, and supports direct external air inlet, compensation air, primary and secondary air control, post-combustion and high airtightness. Optional additions include a barbecue kit, fan, façade, log rack and a range of frames and ready-to-fit fireplace options depending on the final installation approach.

Expert Insight

The 22/70 is the most space-conscious option in the single-faced range, but it still offers a substantial output and a true retractable-fireplace experience. The most important technical feature is not just the rising glass itself, but the way the stove is designed to manage air in both closed and open-fire modes. That allows it to offer the atmosphere of an open fire without behaving like a traditional inefficient open hearth.

The integrated frame system is also significant. It is designed so the surrounding finish can sit very close to the fire, which is one of the main reasons the Stûv 22 reads so cleanly in architectural projects.

Suitability

The Stûv 22/70 Single-Faced Wood Burning Fireplace is well suited to high-end built-in fireplace projects, modern renovations and interiors where wall space is more limited but a premium architectural fire is still required. It is a strong choice for customers who want the Stûv 22 experience in its most compact one-sided format.
