£479.00 £1,199.00

Upgrade your kitchen with the Fohen Flux 4-in-1 Instant Boiling Water Tap - a modern flexible-hose tap finished in striking Gunmetal Grey for a bold, contemporary look. Designed to bring convenience, control and versatility to the sink, the Flux combines standout styling with everyday performance.

The Flux's modern digital touch control replaces the traditional boiling water handle, creating a sleek and uncluttered appearance. Illuminated colour indicators provide instant visual confirmation, glowing red for filtered boiling water and blue for filtered cold or chilled water. Designed with family safety in mind, the child-lock function is activated by pressing and holding the touch control before boiling water can be dispensed, offering an extra layer of protection without compromising convenience.

This innovative system delivers mains hot, mains cold and instant filtered boiling water, with the option to choose either filtered cold drinking water or filtered chilled water from one streamlined tap. The flexible pull-out hose makes everyday tasks easier - from rinsing vegetables and washing pans to reaching every corner of the sink.

Supplied as a complete system with an under-sink boiler and water filter, the Flux offers fast access to boiling water alongside clean, great-tasting filtered water. You can also upgrade to a filtered chilled water system for an additional cost, delivering refreshing chilled water straight from the tap. Please note: installation requires an electrical socket beneath the sink for the boiler (and chiller, if selected).

We have designed our boiling water taps to be extremely energy-efficient, costing less than 10p a day to run. The greatest saving, however, is time. With a boiling water tap, you'll no longer have to wait for the kettle to boil or juggle multiple kettles of water.

Kettles cost a few pence per boil, which means they may cost more to run if they're used multiple times a day.

Yes, our taps are designed with safety in mind. The spring-loaded mechanism prevents little ones from accessing boiling water, while also switching the boiling water function off when you move away from the sink. What's more, at 98°C, the near-boiling water is dispensed in a steady stream without spluttering.

Our taps are safer than kettles for a few reasons:

They can't be moved around the room, unlike a kettle
They don't become hot to the touch, unlike a kettle
They have a spring-loaded mechanism to prevent children from accessing boiling water
