Is your washing machine old?
Then it may be costing you money, as the following recent report found:
“….in order to achieve the same washing performance as a modern machine does in a 40 °C wash, a 15-year-old washing machine must be operated in a 60 °C programme, and a 30-year-old one in a 90 °C programme (on average). By contrast, on average a 15-year-old washing machine requires approximately twice as much energy and water as a new one to achieve the same level of performance, and a 30-year-old washing machine about four times as much.”
