About us

From a simple question to a global solution.

Sustainable water consumption should become the new standard. That is why GREENJET was founded in November 2021.

Our mission

An end to needless water and energy waste.

The question at the start: why are millions of litres of hot water wasted every day when better technology has long existed? It was never only about less water, but about uniting comfort, efficiency and sustainability in one intelligent solution.

Measurable.Economical.Simple.

Up to 66 % less water consumption
Significantly reduced hot-water energy demand
10-year manufacturer warranty
Full shower comfort, constant pressure
TÜV-certified performance
