hansgrohe CoolStart faucets are eco-friendly, only running cold water in the handle center position – whereas with standard faucets, energy is consumed immediately. With CoolStart technology, your plumbing doesn’t get filled with unneeded hot water. The result: fewer resources, CO2 emissions, and 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 questions are on everyone’s mind. The best place to look for answers is in the energy consumers in our homes that we use several times a day, like lavatory faucets. The hansgrohe CoolStart principle is as simple as it is ingenious: With these faucets, warm or hot water only flows when you really need it. You only call up the necessary energy when you actively move the handle to the left.
Standard faucets work differently: The continuous flow heater, circulating pump, and other water heaters already start up when you press the lever in the home position. But we don’t always need hot water, do we? When it comes to having a drink, washing our hands, watering flowers, or getting some cleaning done, cold water is often enough. That’s exactly the trick: CoolStart faucets only heat water when you see a need. You alone decide how high the temperature should be – however many times a day. Typical hansgrohe: with an economical CoolStart faucet, you can enjoy full convenience and beautiful design.
Our example calculation shows how much: A household of four using a hansgrohe CoolStart faucet for 20 minutes a day for a year can consume 508 kilowatt hours less energy than with a conventional faucet. To make this figure less abstract – with 500 kWh, you could:
By way of background: Roughly 90% of a household’s CO2 emissions are the result of providing hot water for the shower, bath tub, and sink. An example calculation: A household of four that heats water with gas can use 51 pounds less CO2 annually with a CoolStart faucet than with a conventional faucet. Specifically:
This is especially important in times when energy prices are skyrocketing. An example calculation: A household of four that heats water with gas can save $61.55 USD every year by replacing their old faucet with a CoolStart model. By the way:
