Clean-burning built-in bioethanol fireplace with a real dancing flame. Designed as a striking architectural feature, it delivers warmth and atmosphere without a chimney or gas connection — just pure, elegant ambience for contemporary interiors.

Foco One 800 Slim
Not every wall has the depth for a standard built-in fireplace. The Foco One 800 Slim is designed for exactly those situations — a one-sided built-in bioethanol fire with a depth of just 20 cm, built into walls that a conventional insert would never fit. At 80 cm wide, it delivers a genuine, adjustable flame without demanding structural compromise, making it one of the most versatile built-in fires in the Foco range.
A real flame in a 20 cm recess
The 3.5-litre Superior manual burner produces up to 3.2 kW of heat output with a burn time of up to 7.5 hours per fill — enough to run through a full evening without interruption. The flame is adjustable, so intensity and burn duration can be balanced to suit the room. Rooms up to 70 m³ are comfortably within range. A tempered glass panel is included, positioned in front of the flame to stabilise it against draughts and enhance the visual clarity of the fire.
Designed to disappear into the wall
The 4 mm stainless steel frame with black powder-coated finish is the same construction used across the entire Foco range — durable, neutral, and visually restrained. The Slim profile means the fire sits flush with a shallow partition wall without any visible projection or awkward surround. The black finish ensures the frame recedes and the flame takes full focus.
No electricity, no certification required
The Foco One 800 Slim requires no electrical connection and no specialist certification to install. The frame is set into the prepared wall opening, the glass panel is positioned in front, and the burner is placed inside. If the wall is combustible, fire-rated insulation board — Skamotec fire boards or similar — should be used to line the recess before installation.
Clean-burning and straightforward to use
Bioethanol produces no smoke, soot, or ash. The burner is lit with a long-reach lighter and extinguished by closing the burner cover. Adjust the flame height by varying the size of the burner opening. Fill only with the fuel you intend to burn in a single session.
