6. Water consumption per cycle in litres
7. Noise in the washing and spinning cycles in dB(A)
For tumble dryers, the energy efficiency scale is calculated using the cotton
drying cycle with a maximum declared load. The energy efficiency index is
in KWh per kilograms of load. Different scales apply for condenser and vented
dryers (as shown here in Figures 6.7 and 6.8).
The label also contains:
1. The energy consumption per cycle
2. The total cotton capacity
3. Whether the unit is vented or condensing
4. Noise in dB(A)
For combined washer dryers, the energy efficiency scale is calculated using
the cotton drying cycle with a maximum declared load. The energy efficiency
index is in KWh per kilograms of load. Different scales apply for condenser
and vented dryers (shown in Figure 6.9).
The label also contains:
1. The energy consumption per cycle (washing and drying)
2. The energy consumption per cycle (washing only)
3. Washing performance, with a class from A to G
4. The maximum spin speed
5. The total cotton capacity (washing and drying separately)
6. Water consumption for a full load washed and dried; note that con-
denser dryers may use significant amounts of water on the drying
cycle
7. Noise in dB (A) (separately for washing, spinning and drying)
