Stuv 21 - 135 - Fireplace

The Stûv 21-135 is the largest single-sided model in the acclaimed Stûv 21 fireplace range, designed to deliver a spectacular panoramic view of the fire while maintaining a clean, frameless architectural appearance. Featuring Stûv’s signature retractable guillotine glass door, the 21-135 allows you to enjoy the ambience of an open fireplace or the efficiency of a high-performance slow-combustion heater with the door closed. Its expansive 135cm-wide viewing area makes it an exceptional centrepiece for luxury homes, large open-plan living spaces, and bespoke architectural projects.

Manufactured in Belgium, the Stûv 21-135 combines advanced combustion technology with minimalist design. The frameless retractable door disappears completely from view when raised, while the large combustion chamber delivers powerful heat output and accommodates substantial firewood loads. With optional convection systems, external air connection, and a wide range of fascia and cladding options, the Stûv 21-135 offers outstanding flexibility for both contemporary and traditional interiors.
