In summer, the situation is clear: if you want to save energy, the environment and your wallet, you can hang your laundry on a clothesline or drying rack and let the sun do the work. A tumble dryer is usually not necessary.
In winter, however, the question of the more environmentally friendly choice is not that easy, because it really depends on the circumstances whether you should use a drying rack or a tumble dryer.
However, not everyone has the opportunity to do so, so the laundry has to be dried in the apartment – and here you should be particularly careful in winter, because damp laundry increases the humidity significantly. In order to avoid mold growth, good ventilation must be ensured.
A open window in the freezing cold does not exactly create a feeling of well-being – and if you live in a small apartment, for example a 1-room apartment, it is not at all possible to ventilate the room continuously for days at minus temperatures. In order to get to acceptable temperatures here, the Heating counteracted.
And when that happens, the drying rack can indirectly help horrendous heating costs worries. In this case, therefore, it can cheaper be, one clothes dryer to let it run short.
