Electrolux energy saving system, as standard on versions “A” & “B”, cuts h e a t i n g c o s t s b y h a l f a n d s a v e s between 20 to 30 kW/h:

The energy saving device reduces the electric consumption by pre-heating the incoming cold water using the steam from

During the dishwashing process, the machine is taking in cold water via the

c o n d e n s e r a n d a t t h e s a m e t i m e t h e e x h a u s t f a n i s e x t r a c t i n g t h e s t e a m , generated in the rinsing and washing z o n e s , f o r c i n g i t t o p a s s t h r o u g h t h e aluminium lamellas of the condensing unit. The steam condenses on the cold fins and the heat is transferred to the cold incoming water. The water temperature is increased from ~ 10 °C to ~ 50 °C, that means an initial energy saving by heating up the incoming water of ~ 40 °C.

The extra price of an “A” or “B” version compared to a “C” version will normally be repayed within one year of use, taking in consideration energy savings and the
