Domestic Washing Machine - Appliance Ownership Levels


Estimated ownership of UK domestic washing machines and washer dryers (percentage of households) Historic data suggests that the average annual unit energy consumption for a domestic washing machine in the UK is 268 kWh (1999). It is assumed that a 60C wash uses 40% less energy than a 90C wash; and a 40C wash uses 40% less energy than a 60C wash for estimated number of uses of each cycle). An average load capacity of 5.58 kg in 2006 was assumed, rising by 0.025 kg/year to allow for the future availability of larger capacity machines. Washing machines typically do not adjust water and energy consumption if a smaller load is washed. Average water consumption per wash was estimated to be 50 litres (2006); 80% of energy consumption is for heating water in the wash phase.
It is assumed that the best available appliances will be A (2006-2009) and A+ (2010-2020).
