Converting water consumption into litres per year from new EU energy labels - KBCN1548
The following conversion factors may be used to convert the water consumption on new EU energy labels from litres per cycle (L/cycle) into litres per year (L/year):
Dishwasher: multiply water consumption figure on EU energy label by 280 (to go from L/cycle to L/year).
Washing machines: multiply water consumption figure on EU energy label by 220 (to go from L/cycle to L/year).
This follows equivalent guidance for converting energy consumption (see
KBCN1462).
25 Aug 2023 - Correction to 'typo error' for dishwasher conversion factor - previously shown as 208, now corrected to 280.
Washer dryers - KBCN0699
Where a washer dryer is specified, the water consumption figure for the wash and dry cycle should be used.
The drying cycle of a washer dryer is taken into account because it usually uses water during this drying process (e.g. for cooling during the drying cycle) and in some cases, this water usage can be significant.
