Home laundry is becoming more and more convenient and efficient – washing products that can handle any kind of dirt, skilled washing machines. But to wash laundry is only half the battle – it has to be dried somehow.
Back in action fast
A washer-dryer, like any other appliance, consumes energy. And that means it spends it more or less sparingly. For an objective assessment of energy consumption, there are standard criteria developed in the EEC. They are obtained by a single scale, allowing you to compare between the models produced by different companies and countries.
In terms of energy consumption, there are gradations from Class A to G. With A – the best results, low consumption, G – high. The figure in kWh corresponds to the test readings based on the drying program “cotton linen” and the residual moisture content for “cupboard storage”. Energy class C is the most common. The difference in consumption between it and class G is about 0.3 kWh per 1 kg of laundry.
One important factor affects energy consumption – in what condition the laundry enters the machine, in other words, there is a difference if it is spun at 800 or 1600 rpm. By the way, the latter speed allows drying one third faster, and thus saves energy.
