Washing Machines

How much does it cost to run a washing Machine?

For washing machines the energy efficiency scale is calculated using a cotton cycle at 60°C (140°F) with a maximum declared load. This load is typically 6 kg. The energy efficiency index is in kWh per kilogramme of washing.

With advances in energy efficiency nearly all washing machines are now A rated and so A+ and A++ ratings have been introduced. So is it worth basing a purchasing decision on the energy rating? In the table below are some examples of the annual running costs of 3 different washing machines rated A, A+ and A++.An A++ machine saves approximately 4pence per wash or £ 10 per year over an A rated machine. This difference is pretty small, especially if the A++ rated machine costs £ 100 more! Also reliability and longevity need to be taken into account. The running costs of a machine are not just energy consumption, it includes repairs and how long it lasts before it has to be replaced.

The annual running costs are based on a single wash each day
Energy rating Energy consumption kWh/cycle Cost per wash (Carbon Dioxide Emissions) Cost per year (Carbon Dioxide Emissions)
A 1.52 £0.234 (0.6kg) £85.498 (203.8kg)
A+ 1.36 £0.209 (0.5kg) £76.498 (182.3kg)
A++ 1.2 £0.185 (0.4kg) £67.498 (160.9kg)

Because the energy cost differences are so small; it should not be used as the basis for a buying decision. The number one priority should be to buy a good quality reliable machine that fits your budget. A washing machine that breaks down regularly, requires expensive spare parts and needs replacing far too soon is bad for your wallet and the environment, even if it is A+ rated.

Can you give me any data on the energy use of washing machines using different washing temperatures e.g. 30,40, 50, 60oC?

Yes, search for the (online) thesis on washing machines by Emir Lasic, University of Bonn. He tested nine machines on the market, ranging from 5kg to 11kg max load. For each of them the electric energy consumption was registered for washes at 30°, 40°, 60°C and for full, 3/4, 1/2, 1/4 (and empty) drum filling. Sinthesis and raw data are in the thesis.

Hi Patrick. can you be more specific. i.e. is it data about microwave ovens you are after or is it habits in the use of them in a single person flat?CheersRich ard

I am trying to work out the average annual electricity consumption in a single person flat, excluding space heating. I wonder if you have any figures for microwave ovens?ThanksPat rick Fisher
