Only those who know how much water is actually consumed can take appropriate measures. The first step should therefore always be to measure the water flow in showers and washbasins using the bucket test bucket test. Afterwards you calculate with the savings calculator to calculate your personal savings potential.

Washbasins can be equipped with flow restrictors can be easily reduced to 5 liters per minute.

With showers, this is a bit more challenging. Conventional economy showerheads or flow limiters do reduce hot water consumption, but they also reduce showering comfort. Additionally, if everyone were to switch to a low-flow showerhead, it creates a lot of waste.

That's why, as part of this initiative, you can buy a small "mini turbine for the shower" at a discounted price. This is simply screwed in between the shower fitting and the shower hose and - while retaining full showering comfort - reduces hot water consumption by around 40%. The patented system uses the Venturi principle to generate a strong water-air mixture, which guarantees a powerful shower spray despite the reduction in water flow.

For showers with a flow rate of over 8 liters per minute, this allows you to save hot water and still enjoy full showering comfort.
