The RAIS Nexo 100 Bio Bioethanol Fireplace combines a compact architectural form with the convenience and flexibility of automated bioethanol operation. Defined by its strict cubic design, sharp lines and balanced proportions, it creates a clean contemporary focal point for modern living spaces.
At 1025mm high, the Nexo 100 Bio is the more compact option within the Nexo Bio range. Its reduced height makes it particularly suitable for rooms where a lower-profile appliance is preferred, while retaining the same distinctive angular styling and controlled burner performance as the taller models.
The fireplace requires no chimney or permanent fixed installation, giving greater freedom when choosing its position within a suitable room. It can be repositioned when necessary, although a grounded 230V electrical connection is required to power the automated ignition, controls and integrated monitoring system.
The electronically controlled burner provides an adjustable heat output from 1.6kW to 3.4kW, together with a 2.5kW ECO mode. This allows the flame and heat level to be adapted depending on whether the fireplace is being used primarily for ambience or to provide more noticeable warmth.
A generous 7.8-litre fuel tank provides an estimated burn time of up to 31 hours, depending on the selected output level. This extended running time reduces the need for frequent refilling and makes the appliance practical for both regular use and occasional entertaining.
Controlled operation is supported by an integrated monitoring system that manages ignition, operation 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 managed operating experience than a basic manually filled bioethanol burner.
The appearance of the flame can also be customised using decorative elements within the combustion chamber. Ceramic logs create a more traditional firewood-inspired look, while decorative glass or stones provide a cleaner and more minimalist expression. Each option is designed to complement the fireplace and integrate naturally with its precise architectural form.
Further personalisation is available through a choice of six colours, premium handle options and either a steel or glass door. This allows the Nexo 100 Bio to be tailored to suit a wide range of contemporary interiors.
With its compact proportions, automated operation and flexible flueless design, the RAIS Nexo 100 Bio is an excellent choice for customers wanting a real-flame fireplace with a clean, structured appearance.
