Enjoy hot water selectively and reduce energy costs.
Hansgrohe's CoolStart technology means that only cold water will flow out when set to the middle position. Whereas in standard mixers the continuous flow heaters or circulation pump start up immediately when in the middle position, in CoolStart mixers the piping system does not fill up unnecessarily with hot water. When you move the lever to the left, hot water is added. You decide how high the temperature needs to be. It is not possible to move the lever to the right.
To sum up: CoolStart reduces energy consumption, and therefore CO2 emissions too. This means that Hansgrohe's latest idea automatically reduces the burden on both the environment and your wallet. The innovative mode of operation (the lever for the hot water can only be moved to the left) marks a new trend in the world of bathrooms.
Modern mixers with energy-saving functions – typical Hansgrohe
And in conjunction with EcoSmart, you can also save precious water – up to 60 percent in fact.
