Short programme running times, low energy consumptionMiele’s EcoDry technology guarantees short drying times throughout the entire service life of your appliance. In systems without EcoDry, the heat exchanger may clog with fluff over time. This results in less warm air inside the drum to absorb moisture from the laundry. This extends the programme running time required to achieve the desired drying results. brLonger programme running times also mean that the heat pump has to operate for longer. This increases energy consumption and energy costs. After a certain amount of use, this can mean that the tumble dryer no longer uses energy as efficiently as before.
