🔥 Product description – GMT 900×400 Box wall-mounted bio-fireplace, black structured matt with glass

Imagine an evening when everything slows down. The overhead lights dim, and the soft reflections of the fire begin to dance to the rhythm of the house's breathing. With a single gesture, you ignite the GMT 900×400 Box wall-mounted bio-ethanol fireplace, in matte black with glass, and in seconds you have what you've been longing for after a long day – a natural flame, soothing warmth, a sense of luxury. No chimney. No smoke. No ash. This chimneyless bio-ethanol fireplace runs on bioethanol, so it doesn't require any wiring or permits; simply hang it on the wall, pour fuel into the burner, and light it. Simple, clean, modern.

The minimalist, geometric BOX frame in a textured matte black creates a powerful graphic accent – ​​a stunning addition to lofts, under the TV in the living room, in a hallway alcove, and even in an elegant bedroom. The tempered glass visually organizes the composition, protects against direct contact with the flame, and discreetly "calms" the airflow, giving the wall-mounted bio-fireplace the feel of a gallery piece. It's a detail that instantly elevates the interior's class – and not just in photos.

Inside, a TÜV-certified burner with ceramic wool ensures a steady, predictable flame. The 535 mm flame line is impressive, and the output of approximately 2 kW allows for a 2–3°C temperature increase in an area of ​​approximately 25 m². This is why a bio-fireplace from this series is chosen by residents of apartment buildings and flats: it creates ambiance, adds warmth, looks spectacular – and doesn't require all the "logistics" of a traditional fireplace. Isn't this the perfect solution for a modern apartment?
