Tumble driers

Market evolution needs A+++ ranking.
 There are today on the market tumble driers labelled
as 40% better than A class.
 The proposed labelling scheme would allow a good
differentiation between good and better appliances.
 The top class would represent a challenge and would be
very close to the technological limit.
 The proposed scheme is perfectly aligned with the
proposals on fridges, washing machines and
dishwashers.

Efficiency rating is closer to consumer behaviour.
 Full load and half load cotton programs are used to
assess tumble drier efficiency rating.
 Half load is of major influence with regard for the
energy efficiency class:
Without an excellent performance at half load, the
tumble drier would lose one efficiency class.
 Energy consumption during Standby is included in the
energy efficiency rating.

Bigger is better, sometimes.
 It is better to dry the same quantity of laundry in bigger machines,
if all of them are labelled “B“ according to Commission proposal

Standard Annual Energy consumption can be improved.
 The label should be able to highlight the best tumble
drier for a given load.
 The Standard Annual Energy consumption proposed
could point to sub-optimal choices, with a net increase
in annual energy consumption.
 CECED wishes to propose the following formula for
SAEc, so to foster a fair comparison among product
sizes:
200
SAE C  92  c 

The proposed SAEc will balance the comparison
 It would be more difficult to get to the proposed “B“
class for bigger machines, but without unbalancing the
market

A fair comparison between Gas and Electric.
 Measurement procedures are today different
 Electrical operated and gas operated tumble driers are
measured differently. Any direct comparison will be
possible only when the measurement procedures will be
harmonized.
 Any conversion factor between electric energy and gas
will have to evolve over time:
 The conversion factor depends on the share of renewable
energy in each country.
 Gas operated appliances should be handled separately
