N2 - Domestic washing machines typically spend around 80% of the
electricity on heating water. Most of this can be replaced by more
appropriate heat sources like district heat from combined heat and
power production, or gas heating system. In recent years some
washing machine manufacturers have marketed machines which can
take in both hot and cold water and mix it to the temperature
wanted. Such one machine has been tested in daily household use
over 5 months, with habits of very few hot water washes. The
result is an electricity consumption corresponding to 67 kWh per
year for an average household with slightly adapted washing
habits, or 17% of normal today. If the heat is supplied from
combined heat and power production as in the actual experiment,
CO2-emission is reduced by 81%. With hot water from oil or gas
heaters the reduction will be slightly lower, while with solar hot
water it will be larger.
