Comparison Bosch WLT 24440 white vs Bosch WLK 24247 white

The volume of water used by the washing machine during a standard wash cycle. It is measured while washing the maximum amount of cotton underwear for this model with a normal programme and a temperature of 60 degrees.

When evaluating efficiency, one should consider not only the actual water consumption but also the maximum load. So, for example, a model with a load of 7 kg and a consumption of 49 litres per kilogram of laundry will be more economical than a model of 5 kg with a consumption of 40 litres: the first consumes 49/7 = 7 litres per 1 kg of laundry, the second 40/5 = 8 litres per kilogram. This moment is important, first of all, if a large amount of washing is expected.

Many modern automatic washing machines are equipped with intelligent systems that can adjust the water consumption to the actual load and avoid overspending.

Washing machine with an inverter electric motor.

Such motors are also called brushless because they do not have commutator brushes. Thanks to this feature, the noise level, heating and wear are significantly reduced, which has a positive impact on efficiency, reliability and durability. In addition, the accuracy of rotation speed control is increased. The reverse side of the coin is the rather high price of such machines.

When selecting a washing machine based on the number of programs, it's important to keep in mind that having 12 to 16 modes is typically sufficient. More programs, such as 25 or more, may simply offer variations of the same standard programs with different settings for duration, temperature, spin speed, etc. This may not necessarily provide a wider variety of programs. Additionally, machines with the same number of modes may have different specific sets of programs. While more modes increase the possibilities for selecting an optimal mode, it also significantly increases the cost.

The quality of the machine spin mode. The spin class depends on the residual moisture content of the laundry after the end of the washing programme and is indicated by the Latin letter from A to G, where A is the best efficiency, B and C are good, D, E are medium, F, G are very weak. The quality of the spin is closely related to the maximum number of revolves of the drum in this mode. Naturally, machines with better spin quality are more expensive, other things being equal.

This parameter characterizes the efficiency of electricity consumption by the washing machine. Classes are designated in Latin letters from A to G, in ascending order of energy consumption. At the same time, in class A there are subclasses "A+", " A++ " and "A+++"; more pluses means less energy consumption, and the most economical option to date — A +++ — outperforms class A by almost a third.

Machines of classes A + and above are today considered economical, class A — medium, lower classes — high consumption. However, indicators below A are typical for semiautomatic low-cost models. As well as for units with dryers (see above) in which high energy consumption is simply inevitable.

The maximum noise level produced by the machine during operation. Most often indicated for spinning — this is the noisiest mode of operation; for units without spinning (such as semiautomatic devices), this paragraph indicates the overall volume or the volume in the noisiest mode.

The quieter the machine works, the more comfortable it is for others. This moment is especially critical if there are small children in the house. However, the decibel used to measure loudness is a non-linear unit, and the actual noise level is best estimated from comparative tables in special sources.
