The Stûv 6-in 86×60 Wood Burning Insert is the largest model in the Stûv 6-in range, designed for customers who want the broadest fire view, the highest nominal output and the most substantial built-in presence in the collection. It brings together the same core Stûv 6 design principles of compact depth, wide flame view and efficient combustion, but on a larger scale suited to more ambitious fireplace projects.
The broad front opening and taller format make this model particularly striking in larger rooms and feature chimney breasts. The cast iron combustion chamber supports durability and thermal performance, while the curved internal profile helps create an expanded view of the flames. The insert supports natural or fan-assisted convection, with optional ducted convection available, and can be configured with direct external air supply and either oblique or vertical smoke outlet arrangements.
In performance terms, the 86×60 delivers a 10.8 kW nominal output, with an output range of 8 to 13 kW, 75% efficiency and an energy efficiency class of A. It accepts 50 cm logs, weighs 95 kg, and uses a 180 mm flue outlet, 150 mm hot air outlets and a 100 mm outside air inlet. It is the most powerful model in the Stûv 6-in family and the best fit for larger spaces.

Expert Insight
The 86×60 is clearly intended for larger rooms and more statement-led fireplace projects. Its strength is not just output, but also the scale of the flame picture, which allows it to hold its own in larger architectural settings where smaller inserts can look visually lost.
Its 180 mm flue outlet also reflects that larger scale and should be factored into planning from the start.
Suitability
The Stûv 6-in 86×60 Wood Burning Insert is well suited to large feature fireplaces, open-plan interiors, and projects where the inset fire is intended to become a major visual and heating element in the room.
