Capacity
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.
Quick dry
Quick dry programme that dries in a relatively short time. It saves time, but the laundry wears out more than during normal drying and is not suitable for delicate types of fabric.
Drying basket
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.
Self-cleaning heat exchanger
System
for automatic cleaning of the heat exchanger from fibres and all kinds of deposits that prevent easy air circulation. The self-cleaning function is performed during each drying cycle. It extends the life span of the heat exchanger and ensures consistently low energy consumption over the life span of the dryer.
Drain into sewer
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.
Condensate tank volume
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.
Energy class
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.
Noise level
The noise level generated by the dryer during operation. Usually, the specs indicate the maximum volume of the device, in the noisiest mode — when other programmes are running, this figure may be lower. We note that the noise level also depends on the features of the installation: for example, if the machine does not stand firmly on all four legs, vibration from drum rotation can create additional noise. And the tiled walls amplify the sound by creating an echo. Nevertheless, it is best to evaluate the device precisely by the noise level stated in the specifications. And here it is worth bearing in mind that the decibel used to denote loudness is a non-linear value, and it is best to evaluate the actual loudness of the unit using comparative tables. Here is the simplest such table for the volume range in which modern dryers operate:
65 dB — a person's voice in raised tones at a distance of 1 m;
70 dB — a loud conversation of several people at the same distance;
75 dB — loud laughter at a distance of 1 m;
80 dB — motorcycle engine, medium power vacuum cleaner.
The quieter the machine is, the more comfortable it will be to use and the better it will be suitable for a specific environment (for example, if there is a small child in the house or if you plan to run drying at night). At the same time, it is worth considering not only the actual noise level but also the installation location of the device. If the dryer is planned to...be installed in the basement of a private house with thick ceilings and the bedroom is located on the second floor, you can not pay much attention to the noise level: even the loudest unit is unlikely to create inconvenience.
