The Stûv 21

Freedom

Fireplaces designed to be installed without a frame or decorative accessories. The clean lines allow the craftsman who installs the fireplace to give free rein to his creativity.

Retractable glass door

The principle is simple: the glass door slides upwards and disappears behind the wall; the fireplace becomes an open fire, like a hearth. When the door is down, it is very efficient and safe. When the door is partially raised, you can enjoy an open fire without the risk of backdrafts.

Ideal view of the fire

Ideal view of the fire

Regardless of the position of the door, there is no frame to obstruct the view of the fire. Only a 4 cm (1-1/2") metal strip surrounds the hearth. Its look does not change: there is no visible track or mechanism.

Accessible mechanism and tilting door

All of the Stûv 21’s mechanical components are located in the door, which tilts for easy cleaning.

Convection system and insulation

North American safety standards require Stûv 21 fireplaces to be insulated. A prefabricated shell makes it easier to insulate your fireplace and the mandatory convection grills prevent overheating and release heat into the room.

Finishing

Frames

A frame conceals the thickness of the wall into which the fireplace fits and allows for minimalist finishing of the opening.

Finishing

Front Panels

The front panels hide the installation and do not require finishing work. Moreover, the fireplace does not need to be completely fitted into the wall, which reduces the total depth required for the installation.

Ready-to-install elements

Cladding transforms the fireplace into a focal point and gives the fire greater presence: this is the purpose of these ready-to-install elements which allow an installation that requires no finishing work

Cladding for Stûv 21

Stûv 21 fireplaces are designed to be integrated into the building, which is easy with new construction or when major renovations are undertaken.

However, major work is not always an option. Then, cladding is the solution.

Easy to install

The cladding can be installed in a few hours and removed as quickly as it was installed, in case you move.

Integrated convection system and wood rack

Available in several shades

Here is a series of subtle and contemporary shades that harmonize with the colour of the fire. These colours give off a different feel as the ambient light changes throughout the day.

Rust finish

The rust finish

This look is obtained through a natural oxidation process in an outdoor environment. The process is stopped once a nice rusted look has been obtained. This means every piece is unique!

Accessories

Stûv accessories are designed to make your fireplace easier to use.

  • Stûv 21 fire screen

    Used when the retractable glass door is open, it allows you to enjoy the open fire safely.

  • Damper

    A damper will prevent undesirable airflow, when an outdoor air intake is installed.

  • Mobile log rack

    Practical and mobile, this log rack is the ideal solution for storing your wood. Its ease of handling makes moving it effortless. It is the perfect complement to any type of fireplace.

  • Hygrometer

    Stûv fireplaces are designed to only burn wood with a level of humidity under 20%. We recommend this small but indispensible accessory to measure the level of humidity, so you can enjoy your fireplace to the full.
