Chesneys Alchemy Linear Ribbon Burner RB700

Chesneys Alchemy Linear Ribbon Burner RB700

The Chesneys Alchemy Linear Ribbon Burner RB700 brings the visual appeal of a contemporary real flame fire into modern interiors without requiring a traditional chimney or flue system. As part of the Alchemy Bioethanol collection, this linear burner produces a striking ribbon flame effect that suits architectural feature walls, room dividers, media walls, and bespoke fireplace designs.

Its clean lines and minimalist profile make the RB700 a strong fit for contemporary homes, luxury apartments, and commercial interiors where design and atmosphere matter as much as heating performance.

Contemporary Design with a Striking Ribbon Flame

The RB700 stands out through its continuous ribbon flame, which creates a bold line of fire across the burner. This effect produces a dramatic focal point that differs from a conventional fireplace and enhances the visual identity of a room.

Each unit includes an anti-reflective glass upstand fixed to the top plate. This protects the flame from draught disruption while preserving clear visibility from multiple angles.

The burner also uses a V-shaped flame channel that stabilises the flame pattern. This design reduces movement caused by air circulation, helping the flame maintain its impact even in open-plan spaces.

Flexible Installation Options

The Alchemy RB700 offers a high level of installation flexibility.

Homeowners can use it as a freestanding fire visible on all four sides to create a dramatic centrepiece. Designers can also configure it with fewer exposed sides to suit custom fireplace layouts and architectural features.

For a more integrated finish, installers can set the RB700 into feature walls, furniture, or bespoke surrounds as an inset bioethanol fire.

This flexibility makes it suitable for a wide range of interior projects where a traditional fireplace installation would not be practical.

Efficient Bioethanol Performance

The Alchemy range focuses on improving burn efficiency and extending operating time compared with many standard bioethanol appliances.

The RB700 includes a 5-litre fuel tank and delivers up to 6.5kW of heat on its high setting. At this level, it consumes around 1 litre of ethanol per hour, offering approximately five hours of burn time before refuelling.

On the lower setting, it produces 3.9kW of heat while reducing consumption to about 0.6 litres per hour. This extends operation to up to eight hours on a single fill.

These settings allow users to adjust flame intensity, heat output, and fuel use depending on room conditions and preference.

Advanced Alchemy Bioethanol Technology

The Alchemy collection uses patented combustion technology to improve burn efficiency and extend operating time between refills. This system produces a cleaner, more controlled flame that enhances the ambience of a real fire while maintaining the convenience of bioethanol fuel.

The RB700 also works well in smaller rooms compared with many other ethanol appliances, giving designers more flexibility when planning interior layouts.

A Stylish Solution for Modern Homes

The Chesneys Alchemy Linear Ribbon Burner RB700 offers a contemporary fire feature that combines strong visual impact with flexible installation options. Its linear flame effect, adaptable configuration, and efficient bioethanol performance make it well suited to modern interiors where design plays a central role.

Whether installed in a bespoke media wall, a luxury room divider, or a minimalist inset fireplace, the RB700 creates a striking focal point while delivering the warmth and atmosphere of a real flame.
