hansgrohe CoolStart taps are eco-friendly, only running cold water from the handle positioned in the center. This is an improvement from standard taps where energy is consumed immediately. With CoolStart technology, your water system does not get filled with hot water at all times. 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 generate less CO2? What can we do to combat climate change? These are environmental concerns that affect everyone. The best solutions to these concerns are to identify the sources which we consume energy in our home, multiple times a day. For example, basin taps.
The hansgrohe CoolStart concept is as simple as it is ingenious: Warm or hot water will only flow out of hansgrohe CoolStart taps when you actually need it. This means that you only use the energy when you move the lever handle to the left.
Standard taps work differently: Most of the water heater systems such as continuous flow heaters and circulation pumps start to heat up the water as soon as you move the lever to turn on water flow. But it is not every instance that we need warm water. Where it comes to drinking, washing our hands, water flowers or light cleaning, cold water is often enough.
With CoolStart taps, water is only heated when you need it. Plus, you can decide the temperature of the water in every instance it is needed. This means that we consume water and the energy to heat the water at the appropriate level only when required. In this way, we save water, save energy and save money. This is typically hansgrohe: Enjoy total comfort and beautiful design with an economical CoolStart tap.
How much? Here’s our calculation for the scenario with a four-person household: By using a hansgrohe CoolStart tap for 20 minutes everyday in a year, the household will consume 508 kilowatt hours less energy than with a conventional tap. To put this into absolute savings, 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. Using the scenario with a four-person household who heats water with gas, it is possible to consume 23 kilograms less CO2 per year with a CoolStart tap than with a conventional tap. To put this into absolute savings:
In times when energy prices are soaring, reducing consumption and saving is important. A four-person household that heats water with gas can save 61.97 euros every year simply by replacing their conventional tap with a CoolStart tap. In this way:
A CoolStart tap will pay for itself after less than two years with the amount saved!
