GROHE Red can do much more besides delivering kettle hot water instantly- thanks to the mixing valve.
If your kitchen only has a cold-water supply, you can use the GROHE Red boiler to provide warm water. When the boiler is connected to the mixing valve, it mixes boiling water with cold water from the mains supply, to deliver warm water to the mixed water lever of your tap. Thanks to the Coldfill installation, there’s no need for a water-heater. But assuming you have a warm-water supply – there’s still a waiting-period till the warm water arrives and meanwhile the water is running away down the drain. The mixing-valve intervenes, mixing in kettle hot water to cold to compensate and maintaining a constant, thermostatically controlled, warm water temperature. With the Hotfill installation, warm water becomes available immediately. Saving waiting. Saving water. The mixing valve is available as an additional accessory and can be combined with every GROHE Red set.
