Innovative Water- and Energy-Saving System for the Shower
Save up to 50% on water while enjoying 100% shower comfort

Save water and energy while showering!

With the innovative Ecowaterjet by rabmer®

About one-third of total water consumption in households, hotels, and sports facilities is used solely for showers and personal hygiene—a very large amount! That’s where saving water really pays off. However, conventional water-saving showerheads have one major drawback: less water also means less showering comfort. Our water-saving shower insert offers the perfect solution: This small, easy-to-install water-saving device swirls the water to create a powerful air-water mixture that saves up to 50% in water and energy—and thus also reduces costs—without compromising the intensity of the shower spray.

Reduce water consumption, save energy, and lower operating costs.

Hot water consumption—primarily in showers, but also at sinks—results in high energy, water, and wastewater costs, particularly in the hospitality industry. Added to this are increasing ESG and taxonomy requirements. Rabmer’s water-saving system addresses precisely this issue and makes it possible to reduce water and energy consumption during showers.

The innovative Ecowaterjet by rabmer® shower insert can be installed quickly and easily and creates a highly swirled mixture of water and air that can save up to 50 percent* in water and the energy required to heat it.

You can use our savings calculator to determine your individual potential savings on water, energy, and costs based on the consumption data you enter.

They ensure hygiene
The powerful water turbulence keeps the showerhead and hose free of deposits and biofilm. This significantly reduces the risk of bacterial growth and Legionella.

You can reduce CO₂ emissions
Lower hot water consumption also reduces the energy required for water heating. Depending on the energy system used, this can help reduce operational CO₂ emissions.

You are using a certified system:
This water-saving device from Austria has been tested by TÜV Austria and independent experts. The shower insert has been awarded the Federal Environmental Label.

How the Water-Saving Ecowaterjet Works

This innovative shower insert simply screws onto the shower hose—quickly and easily. Its funnel shape significantly accelerates the water flow, and negative pressure causes air to be drawn in and mixed with the water.

The result: a voluminous, swirling water stream that uses up to 50% less water without compromising comfort. At the same time, the powerful stream cleans the showerhead and hose, prevents mineral deposits and biofilm, and reduces the risk of germs and Legionella.
