hansgrohe CoolStart taps are environmentally friendly: Only cold water will flow when the handle is in the middle position, whereas energy is immediately consumed with standard taps in the same position. So with CoolStart technology, your pipe system will not be filled with warm water unnecessarily. The result? Fewer resources consumed, lower CO2 emissions, cheaper costs. Good for the environment and your wallet!
Where can we save energy, how do we send less CO2 into the atmosphere, what can we do to combat climate change? These are questions that concern us all. The best approach is to find solutions for the energy consumers in our home that we use several times a day. Basin taps, for example. The hansgrohe CoolStart concept is as simple as it is ingenious: Warm or hot water will only flow out of these taps when it is actually needed. You only use the energy when you actively turn the lever handle to the left.
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, right? Cold water is often what we want when pouring drinking water, washing hands, watering flowers or cleaning. And that’s the kicker: Water is only heated in CoolStart taps when you see a need for it. You alone decide how hot to make it – several times a day. Typically hansgrohe: Enjoy total comfort and beautiful design with an economical CoolStart tap.
How much? Here’s our example calculation: A four-person household that uses a hansgrohe CoolStart tap for 20 minutes every day for a year can consume 508 kilowatt hours less energy than it would with a standard tap. To put this into perspective, with 500 kWh, you can:
By way of background: Roughly 90% of CO2 emissions in the bathroom occur in the utilization phase i.e. through the providing of hot water for the shower, bath tub, and sink. Example calculation: A four-person household that heats water with gas can consume 23 kilograms less CO2 per year with a CoolStart tap than with a conventional tap. To put this into perspective:
In times when energy prices are soaring, this is so important. Example calculation: A four-person household that heats water with gas can save 61.97 euros every year simply by replacing their old tap with a CoolStart model. By the way:
