ELLESS - Best at water saving - in reality

Consumers are often misled to think that they need to replace the entire mixer in order to obtain best water saving results. This would be the same as forcing consumers to replace the entire fitting to save electricity. As long as the existing mixer is dense and does not need any extensive reparation, replacing old aerators and showers with ELLESS energy efficient water saving devices is all it takes. We have proved, through field studies and contacts with consumers, that water saving does not depend on the mixers, but on the aerators and showers assembled onto them.

ELLESS water saving products can be compared with a low energy lamp. An 11 W low energy lamp saves 49 Wh during one hour of use. ELLESS shower heads save the same amount of energy during 12 seconds, and ELLESS aerators make the same saving during 18 seconds. The ELLESS system allows a maximum water flow of 9 liters per minute in kitchen sinks and showers, and maximum 6-7 liters per minute in bathroom sinks. Users regulate the water flow by themselves to what suits them the best. Consequently, the water flow usually varies between 3,5-6 liters per minute in sinks and between 6-9 liters per minute in showers. Under these circumstances an average household makes a yearly energy saving of 1000-2000 kWh and a water saving of 20-40 m3.

Laboratory tests on aerators and showers are made with taps open to their maximum. In such case, the poduct that obstructs the water jet the most "wins". This is deceiving as, normally, taps are fully open only when one needs to fill something up, a bucket for instance. ELLESS has instead proved to be best at water saving in reality, under normal behaviour and under conventional circumstances.
