Get the ultimate time-saving convenience with kettle-hot water from the new Grohe Red Duo single-lever tap

Now you can get kettle-hot water instantly from the Grohe Red Duo to get a flying start on a range of kitchen jobs. The Grohe Red Duo kitchen mixer in stylish Hard Graphite delivers water heated to 99° instantly. The water is perfect for making tea and coffee, but also filling pots and preparing meals. The kettle-hot water function is activated via the child-safe touch buttons, while standard hot and cold water is controlled via a slim, forward-rotating lever. The high C-shaped spout makes filling pots easy, and it has a swivel range of 150° for further flexibility. Grohe Silk Move ensures smooth, precise lever operation. Safety is paramount with this product - the mixer features an automatic Grohe Child Lock function, operated via the touch buttons. Rated A for energy efficiency, the boiler can also be switched to Holiday Mode, where the temperature is limited to 60° C. Instantly providing up to 3L of heated water, the boiler is made of titanium for excellent corrosion protection and the tap's scratch-resistant Grohe Star Light finish will stay pristine for years to come. The Grohe Red filter also reduces lime scale and heavy metals in the water, prolonging the life of both tap and boiler. Customers may want to also purchase the Cold fill Mixing Valve (40841001) to replace your low-pressure kitchen tap, which mixes mains water with boiling water to give you immediately warm water too, meaning no waiting for water to heat up, and less water wasted.
