The Stûv 21/125 DF Double Sided Inset Wood Burning Stove is the widest double-sided model in the Stûv 21 range, designed to create a dramatic see-through fire between two spaces while delivering substantial heat output. With retractable glass on both sides, it allows the flames to be enjoyed in transparency, making it ideal as an architectural divider.
Its main appeal is scale. The 21/125 DF offers the broadest double-sided fire view in the range, creating a major focal point between adjoining rooms or open-plan zones. As with the rest of the Stûv 21 family, the glass can be raised to create an open-fire effect, while lowering the glass turns it into a high-efficiency closed stove. The mechanical parts are housed in the door, which pivots for easier maintenance and cleaning.
In performance terms, the 21/125 DF offers a rated output of 27.4 kW, an optimal range of 13.0 to 30.0 kW, 75.1% efficiency at rated power and an energy efficiency class of A. It accepts 100 cm logs, weighs 310 kg, and uses a 300 mm flue outlet. It also supports outside air connection, optional barbecue use and multiple cladding or ready-to-fit fireplace solutions.
