hansgrohe CoolStart Technology: Save energy at every turn


hansgrohe CoolStart taps are environmentally friendly. Only cold water flows when the handle is in the middle position. This is unlike standard taps, where energy is immediately consumed once the handle is operated. With CoolStart technology, you won’t be using warm water unnecessarily. The result? Fewer resources consumed, lower CO2 emissions, cheaper costs. The potential for savings is enormous.

Standard taps work differently: Continuous flow heaters, circulation pumps and other water-heating mechanisms kick in as soon as the lever is activated in the middle position. But we don’t always need warm water. Cold water is often what we want when pouring drinking water, washing hands, brushing teeth, watering flowers or cleaning.
