hansgrohe’s tips for saving water

What you can do for the environment and your wallet on a daily basis – with some simple tricks

Water is precious. We should conserve it – for the sake of the environment. Yet all too often, too much of this precious resource trickles down the drains in our bathrooms and kitchens, unnoticed. Some simple water-saving tips and a few small changes to our everyday habits can help to conserve this precious resource, often automatically reducing the energy consumption as well. Because every drop that is saved no longer needs to be heated.

Easy to implement: water-saving tips for everyday life

When washing your hands, cleaning your teeth, or shaving: don’t leave the water running

Depending on the mixer, some 5 to 20 litres of water are lost in this way – every minute!

Water-saving tip 1: Turn off the water when you don't actually need it. When cleaning your teeth, you can use a tooth brush tumbler. A wet shave requires only a small amount of water, which you can run into the bowl before shaving.

Constant dripping wastes thousands of litres every year

A dripping mixer may well have little effect on the individual water bill. However, the amount of dripping taps adds up when you consider every household – plus the extra consumption becomes an unnecessary factor in water treatment for the municipality.

Water-saving tip 2: Get dripping mixers sealed as soon as possible. Sometimes simply replacing a seal is enough to do something good for the environment.

For a full bath, you need at least 140 litres of water

Water-saving tip 3: Take a shower instead! That way, you consume far less water. Especially if you are using a Hansgrohe shower featuring EcoSmart technology

Incidentally, the most economic showers are those such as the Crometta 85 Green hand shower. This Hansgrohe shower consumes just 5.7 litres of water for every minute you spend in the shower (at 3 bar) – while you still enjoy the ultimate showering experience. A bath can be wonderful, but perhaps you could save it for just a few special moments of indulgence per year?

EcoSmart technology: Save water, protect the climate

Water-saving tip 4: Get an EcoSmart mixer or shower. With this water and energy-saving technology, Hansgrohe is promoting greater water efficiency.

EcoSmart in mixers:
Mixers featuring Hansgrohe EcoSmart technology consume up to 60% less water than conventional products. A precision elastomer reacts automatically to changes in the water pressure and changes its shape, ensuring that the water flow is constantly limited – to around 5 litres per minute. Save water and energy the smart way with Hansgrohe EcoSmart mixers – and conserve valuable resources. Without sacrificing any comfort. 

EcoSmart in showers:
Even in the shower cubicle, with Hansgrohe EcoSmart showers you can save up to 60% of water compared with conventional shower heads. The inner workings of the Hansgrohe shower make all the difference: here, the water flow is limited to around 6 to 9 litres per minute. Since this reduction means that less water needs to be heated, EcoSmart also helps you save energy.

A large portion of drinking water is the water used for flushing the toilet

Water-saving tip 5: It's worth installing a flush/stop button or a dual flush system. Small flushes don't usually require more than 3 litres of water. This can save up to 8,000 litres of drinking water per person per year (= 0.8 cubic metres). Your water supply company bill will tell you what that represents in your locality.


Water-consuming appliances: pay attention to energy efficiency and capacity

Water-saving tip 6: When buying a new washing machine, dishwasher, mixer or shower head, pay attention to their energy efficiency class. Which appliances save particularly large quantities of water and energy? Opt for eco-friendly models rated class A, or even better: A+ or A++.

Did you know that lots of Hansgrohe showers and basin mixers have received top marks because of their environmentally friendly features? Check out these products here: WELL – the eco quality seal of the European sanitation industry for water and energy efficiency

Talking of efficiency: don’t run washing machines and dishwashers half empty. Only set the machine going when it is optimally loaded. More often than not, the pre-rinse or prewash program is not necessary. For slightly soiled laundry, lots of washing machines have an environmentally friendly short wash cycle.

Limit hot water consumption – reduce CO2 emissions

Anyone without solar collectors on the roof or not using geothermal energy invariably consumes fossil fuels for hot water provision. Therefore: people who save hot water are also reducing consumption of carbon dioxide, which damages the climate. A household of four people can reduce consumption of CO2 by up to 600 kg per year by using water-saving showers.

Water-saving tip 7: A Hansgrohe CoolStart mixer reduces your energy consumption – and hence it automatically reduces CO2 emissions too. This innovative technology reduces the burden on both the environment and your wallet, and marks a new bathroom trend.

Incidentally, did you know that Hansgrohe SE is the world's first sanitation industry manufacturer to introduce environmental life cycle assessments for hand showers?

Consider the environment when washing the car

Water-saving tip 8: Car washes that bear the Blue Angel eco-label use the wash water multiple times. It is cleaned in a recycling system, and oil residues are removed. An environmentally friendly car wash such as this not only provides you with a clean car, but is also easier on the environment.

AirPower technology: less water, more fun

Water-saving tip 9: Use less water, but more air. That was the simple yet ingenious formula used by several Hansgrohe developers in the early noughties. This was how the Hansgrohe AirPower technology, which enjoys worldwide popularity, came into being. Enjoy feeling luscious pearls of AirPower water all over your skin when showering. Water enriched with air makes the droplets particularly plumper, lighter and softer. The shower spray is more voluminous, yet you save water at the same time. AirPower – enjoy a more intensive, eco-friendly shower.


Single lever mixer instead of two handle mixer. Or Select your shower pleasure – fun at the touch of a button

Water-saving tip 10: It is quicker to set the required water temperature with a single lever mixer than with a two handle mixer, and this reduces the amount of water going to waste down the drain.

Alternatively, you can even opt for a leverless mixer for your wash basin and sink. With Hansgrohe Select technology, the lever disappears altogether. On wash basin and sink unit mixers, therefore, the water can be turned on and off at the touch of a button. This encourages you to save water – and is fun to use, at the touch of a button.

Green lawns are nice, but not at any cost

Water-saving tip 11: Lawns generally do not need watering, even brown grass recovers on its own after getting the next shower of rain. In the rest of the garden you should use water sparingly and only water plants and flowers at dusk. That way, less water evaporates unused on the beds and in pots.

Buying habits have an influence on water consumption

For example, producing 1 kg of paper made from fresh fibres creates 100 litres of waste water, while the production of recycled paper obtained from waste paper uses only 15 litres of water per kg, and conserves resources. 

Water-saving tip 12: When buying toilet paper or writing paper, look out for “Blue Environmental Angel” certification.

Be mindful of conserving resources when grocery shopping

Often, fruit and vegetables have travelled a long way by the time they get to our supermarkets, and a lot of water has been used in producing and processing them.

Water-saving tip 13: Regional products – as well as seasonal fruit and vegetables – are richer in vitamins, healthier and more environmentally friendly.

Returnable bottles protect the environment – and the water balance

A lot of water and energy is lost in the manufacture and disposal of non-returnable bottles.

Water-saving tip 14: Buy deposit bottles. Whether these are made of glass or PET: they limit the consumption of materials and energy.

Use water twice – that would really save water

Grey water processing – the targeted reuse of only slightly dirty domestic water from the shower and bath tub is really smart. The Pontos AquaCycle system from the Hansgrohe brand prepares the waste water for reuse without the use of chemicals: This saves valuable drinking water. Planned in good time, this technology can be easily integrated in new constructions or in the case of a complete redevelopment of projects with a process water requirement from 2,000 litres per day. More about water recycling with Pontos AquaCycle.

This technology is even more profitable when combined with heat recovery. Pontos HeatCycle recovers energy from the grey water before it disappears down the drain, reducing the outlay and costs needed for supplying hot water by up to 20 percent. Good for the environment, good for your purse.
