Comparison Bosch WTH 83001 UA vs Siemens WT 45W459

The maximum amount of laundry that can be loaded into the dryer; in other words, the largest weight of laundry that the machine can efficiently process in one cycle.

Capacity is usually indicated by the weight of the dry laundry. Thanks to this, when preparing the laundry for washing, you can immediately assess whether it will fit in the dryer at a time or, on the contrary, you can get by with a small drying. However, even the most modest modern dryers (and even slim ones up to 50 cm) in most cases hold 7 kg — this is comparable to loading the drum of a medium-capacity washing machine. And in the most capacious models, this figure can reach 10 – 11 kg. It is quite enough for domestic and even professional use (for example, in laundromats or laundries of hotels, etc.). However, the typical figures are drying for 8 kg and models for 9 kg of laundry. Bigger capacity is relevant for industrial equipment and is not found in consumer-level models.

Also, when choosing, note that in the specs the maximum capacity is usually indicated for linen made of cotton fabric. For other, more voluminous materials, the capacity can be noticeably less — for example, the weight limit for wool products is usually 4-5 times less than for cotton.

The internal volume of the dryer drum.

A larger drum can accommodate more laundry, but there is no rigid dependence here: models with the same volume may differ in maximum load. It is because to process a large mass of laundry, one need not only a capacious drum but also an engine of appropriate power. At the same time, in a larger drum, the same mass of laundry will dry more efficiently than in a small one, because laundry will be more freely distributed over the drum, crumpled less, and warm air will better penetrate the folds of the fabric. As a result, for the same drum volume, a model with a smaller load will be more efficient and performant than a model with a larger load. On the other hand, a volumetric drum takes up more space and the dimensions of the dryer are largely determined by the dimensions of the drum.

This function of the dryer prevents the formation of the crease on the laundry as much as possible, which facilitates subsequent ironing. Of course, anti-crease function does not give a full guarantee against creasing, but it noticeably makes life easier for the user. Especially when working with fabrics like linen or in cases where the things themselves are not particularly wrinkled but can crumple with inaccurate drying.

The presence of a drying basket allows you to carefully place woollen items, as well as shoes, which contributes to delicate drying and the laundry does not “fly” around the drum like in washing machines.

Lighting system for the internal volume of the device. It usually turns on automatically when the dryer door is opened - thus reducing the likelihood that some items (especially small and dark ones) will be forgotten in the drum.

This option allows you to automate the process of draining the condensate collection tank (respectively, it is relevant only for dryers with a condensation principle of operation). At the end of the drying process, the condensate accumulated in the tank is automatically drained into the sewer. To do this, a pump and a hose are provided in a dryer with a drain into the sewer. The function of draining into the sewer allows you to significantly simplify the operation of the dryer, while in models without this option, the user must drain the condensate tank manually. Of course, manual emptying does not require much effort because the average condensate collection tank has a volume of about 5 litres, but still not very convenient.

Only condenser dryers have such a tank (see "Drying type"). The larger the tank, the less often you have to get rid of the accumulated liquid. At the same time, in most models, the volume of the condensate tank is standard — about 5 – 6 litres: this is considered the best compromise between capacity and dimensions.

Drying class describes the overall drying efficiency that the machine provides. It is denoted by a Latin letter, where A is the best efficiency, and further in decreasing order ( drying class B is inferior to class A, but exceeds class C). Naturally, higher efficiency machines cost more (ceteris paribus).

The energy consumption class shows not the actual energy consumption but the efficiency of the dryer. In other words, what part of the electricity consumed goes directly to useful work. For dryers, this parameter is especially important because such devices have high electricity consumption. As a result, models with the same capabilities but different energy efficiency classes differ markedly in terms of operating costs (in terms of electricity bills). However, more economical units themselves are more expensive. nevertheless, this difference quickly pays off.

Initially, classes were marked in Latin letters from A(the highest class) and further alphabetically. In the course of technology development, more economical levels of consumption than the original class A appeared — they are labelled as A+, A++, A+++, etc. Actually, the highest efficiency class in modern dryers is exactly A +++ ; level A — A+ can be called good, B — average, C — acceptable.
