Stûv 21 Wood Fireplace

Product Overview

The Stûv 21 is an architectural wood fireplace built to disappear into the space and let the fire take center stage. A frameless guillotine glass window rises or lowers to switch between open and closed-fire operation, and only a slim steel frame defines the combustion chamber, so the view of the flames is as wide as the architecture allows.

Design highlights

• Guillotine glass window for seamless open-fire or closed-fire use
• Frameless bottom edge, so nothing interrupts the view
• Single-face and double-face configurations for through-wall, peninsula, or island installs
• Slim steel frame that gives the fire maximum visual presence
• Simplified access to internal mechanisms for service and maintenance
• Mandatory convection system (standard or linear grilles) specified at quote

Configuration options

Choose a face configuration and chamber size to match the architectural plan. Chimney diameters vary by size.

• Single Face (21 SF): 85, 95, 105, 125. For standard wall integrations.
• Double Face (21 DF): 85, 95, 125. For peninsula and see-through walls between two rooms. (No 105 size in the double-face line.)

Performance overview

• Nominal heat output from roughly 43,000 to 65,000 BTU/h depending on size and face configuration (European testing protocol)
• Heating coverage roughly 1,400 to 1,800 ft²
• Combustion chamber volumes from 4.8 to 8.4 ft³. All chambers accommodate standard 16″ logs and larger.
