Stûv 21

Wood fireplaces and inserts

Stûv 21, a perfect pairing of architecture and fire

Stûv 21 wood fireplaces are manufactured to blend into the decor, the fire becomes the center of attraction. These modern fireplace models also feature a retractable window that can be raised or lowered for an open or closed fire.

Frameless guillotine glass window

Stûv 21 wood fireplace models have a guillotine glass window. There is no frame at the bottom to affect the view of the fire.

Single or double-sided

Stûv 21 wood fireplaces come in many sizes and are available in single or double-sided format to allow for multiple architectural integrations.

A maximum view of the fire

Only a delicate steel frame delimits the combustion chamber of Stûv 21 wood fireplaces, providing a wider view of the fire.

A perfect combination of atmosphere and efficiency

Due to their very large combustion chamber, Stûv 21 wood fireplaces offer abundant warmth and atmosphere at all times.

When performance enhances the fire

1
The air required for combustion comes directly from under the unit through an airtight box specially designed for the Stûv 21 models.
2
A deviator placed at the top of the combustion chamber constrains the smoke in order to moderate the fire and provide better combustion.
3
Once the gases have burned they are evacuated through the flue pipe.
4
The sweeping air flow removes dust due to combustion from the glass providing a perfect view of the flames.
5
The air is taken from the room (via two air inlets located at the bottom of the unit) the convection air circulates along the combustion chamber to absorb the heat.
6
The heated air comes out naturally from the top of the unit (via two hot air outlets intended for this purpose) and distributes a comforting warmth into the room.

Before the Stûv 21

"The Stûv 20, launched in the early 1990s, was Stûv's first real commercial success. In developing Stûv 21, I wanted to consolidate our lead with other innovations such as a retractable tilting overhead door, a fully or partially retractable door and whose lower part would be frameless. Stûv 21s were also the first wood fireplaces on which it was possible to graft transport handles, for the comfort of the installers."

- Gérard Pitance - Designer & Founder
