Development of consumption figures
for dishwashers
Measures aimed at improving efficiency include:
■
Consumption-optimised wash programs
(in conjunction with new detergents)
■
aquaSensor: saves water and time
■
Flow-through sensor: Water quantity
is precisely regulated
■
autoLoad: time and water quantity
is automatically adjusted to the load size
Preserving resources for future generations
At Siemens, we are aware of climate protection and the importance of developing resource-efficient appliances.
We believe that high-performance appliances and lower energy consumption are by no means mutually exclusive.
That’s why we take resource efficiency very seriously, to the extent that our appliances have gained ranks amongst
the most energy and water efficient in their class. With that in mind, we will continue to develop innovative
appliances with cutting-edge technology to ensure the highest efficiency. As part of our commitment,
appliances with high resource efficiency prominently show the Siemens ecoPLUS label.
Production
(raw materials, energy and water consumption)
4 – 9%*
Based on appliances sold in Europe,
about 90% of the total environmental
impact of household appliances occurs
during the appliance’s long service life.
This is why the development of resource-saving
products is Siemens’ most enduring
contribution to protecting
the environment.
Distribution
(energy consumption for transporting the item)
< 0.5%
Disposal
(energy consumption for recycling)
< 0.5%
Operation
(water, energy and chemical use)
90 – 95%*
Raw materials
(non-ferrous metals, steel,
plastic, glass, other)
