Description

Redefine your kitchen workspace with the Arno Flex 4-in-1 Brushed Gunmetal Instant Boiling Hot Water Tap. This all-encompassing system merges industrial-chic design with ultimate utility, dispensing standard hot, cold, filtered 98°C boiling water, and fresh filtered drinking water from one tap.

Why Choose the Arno Flex 4-in-1 Gunmetal?

Industrial Elegance & Durability

The muted, metallic tone of Brushed Gunmetal hides water spots and fingerprints better than polished finishes, making it perfect for busy kitchens. Prefer a square design in this colour? View the Arno Square 4-in-1 Gunmetal Tap.

Versatile Pull-Out Spray

The retractable hose with a 30cm reach offers superior flexibility. Whether you are washing vegetables or rinsing down the sink, the pull-out function makes daily tasks effortless.

Smart Safety Features

Operated by a digital touch screen, the system allows precise temperature control. It also features a child-proof safety lock, ensuring boiling water is never dispensed accidentally.

Installation & Care

The system is supplied as a complete kit (Boiler, Tap, Filter, Pipes) for straightforward installation. A standard electrical socket is required. For detailed diagrams, check our Installation & Care Guide.

To ensure the best water taste and boiler longevity, we recommend changing the filter cartridge every 6 months. Order water filter replacements here.
