Get down to your kitchen jobs without waiting around – thanks to kettle-hot water from the new GROHE Red Duo single-lever tap

Replace waiting for the kettle with the convenience of kettle-hot water from the GROHE Red Duo. The GROHE Red Duo kitchen mixer 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 L-shaped spout makes filling pots easy, and it has a swivel range of 150° for further flexibility. GROHE SilkMove ensures smooth, precise lever operation. Safety is paramount with this product – the mixer features an automatic GROHE ChildLock 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 5.5L of heated water, the boiler is made of titanium for excellent corrosion protection and the tap’s dazzling, durable GROHE StarLight chrome finish will stay pristine for years to come. The GROHE Red filter also reduces limescale and heavy metals in the water, prolonging the life of both tap and boiler. Customers may want to also purchase the Coldfill 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.
