The RAIS Nexo 160 Bio Bioethanol Fireplace is the tallest model in the Nexo Bio range, combining a bold architectural form with the convenience and flexibility of automated bioethanol operation. Its strict cubic design, sharp lines and substantial height create a commanding focal point for contemporary interiors.
At 1600mm high, the Nexo 160 Bio has the strongest vertical presence in the range. It is particularly well suited to large rooms, open-plan layouts and high-ceilinged spaces where a shorter fireplace may feel visually undersized. Despite its scale, the fireplace requires no chimney or permanent fixed installation, allowing greater freedom when choosing its position within a suitable room.
A grounded 230V electrical connection is required to power the automated ignition, controls and integrated monitoring system. The electronically controlled burner delivers an adjustable heat output from 1.6kW to 3.4kW, together with a 2.5kW ECO mode for more measured operation.
The generous 7.8-litre fuel tank provides an estimated burn time of up to 31 hours, depending on the selected output level. This extended operating time reduces the need for frequent refilling while allowing the flame to provide both noticeable warmth and atmosphere.
Controlled operation is supported by an integrated monitoring system that manages ignition, running and refuelling. If an irregularity is detected, the fireplace shuts down automatically and requires a reset before it can be restarted. This provides a more controlled operating experience than a simple manually filled bioethanol burner.
The flame presentation can be personalised using a choice of decorative elements within the combustion chamber. Ceramic logs create a more traditional firewood-inspired appearance, while decorative glass or stones provide a cleaner and more minimalist finish. Each option is designed to complement the Nexo’s precise architectural styling.
Further customisation is available through a choice of six colours, premium handle options and either a steel or glass door. This allows the Nexo 160 Bio to be configured to suit a wide range of design-led interiors.
With its exceptional height, automated operation and flexible flueless design, the RAIS Nexo 160 Bio is an excellent choice for customers wanting a large real-flame feature with a clean, structured and distinctly contemporary appearance.
