Guide: Questions you should ask yourself before buying a Bosch heat pump dryer

What makes Bosch heat pump dryers different from other manufacturers?

In general, it can be said about Bosch that it is one of the best-known and also most renowned manufacturers - especially for household appliances. Bosch stands out for the high quality and durability of its products. Awards such as those from "Focus Money", "Stiftung Warentest" and "Europe's No. 1 brand" are proof of the popularity and quality of the Bosch brand. However, when choosing a Bosch heat pump dryer or a competitor's brand, it always comes down to personal preference and the purpose of using the product. The above examples show that Bosch is an attractive brand for heat pump dryers (as well as other products), but as with so many things, it still comes down to individual preference.
Did you know that we actually have our legislators to thank for the introduction of heat pump dryers? The principle of using heat and waste heat was discovered as early as 1824 by the Frenchman Carnot. However, many manufacturers were sceptical for a long time because of the longer drying time. But due to the uniform energy efficiency class introduced by the government, manufacturers were practically forced to come back with the significantly more efficient heat pump dryers.

What are the advantages and disadvantages of Bosch heat pump dryers?

Heat pump dryers are one of many different types of dryers, each with their own advantages and disadvantages. Heat pump dryers use significantly less energy than, for example, exhaust air or condensation dryers.
Depending on which model you choose, you can save up to 50% energy consumption compared to other models.

So in the long run it may be worth spending a little more. Compared to exhaust air dryers, which release the extracted water into the environment, the heat pump dryer (just like the condensation dryer) collects the water in a container integrated into the dryer, so you can easily place it wherever you want However, heat pump dryers make more noise than competing models, which can be annoying. Especially in smaller flats, this could be perceived as a significant disadvantage. Furthermore, most appliances of this type are somewhat more expensive to buy. You should carefully calculate whether this is outweighed by the lower energy consumption or not

What is the lifespan of Bosch heat pump dryers?

Generally speaking, it is in the interest of anyone who buys something expensive, such as a dryer, to be able to use it for as long as possible. At Bosch, the warranty period for dryers is two years, but this can also be extended by 36 months for a one-off surcharge of €99 In general, it can be said that the lifespan of heat pump dryers is somewhat shorter than that of waste water or condensation dryers. This is due to the sophisticated technology, which makes the appliances more susceptible to repair. However, the quality and thus the lifespan of heat pump dryers, especially from brand manufacturers such as Bosch, has improved significantly in recent years The service life of heat pump dryers can also be extended many times over with the right treatment and care.

What alternatives are there to Bosch heat pump dryers?

Besides Bosch, other well-known manufacturers, such as Siemens, also offer heat pump dryers. But what are significant differences? The following table lists some of these differences
Manufacturer Differentiation
Bosch Bosch heat pump dryers can particularly shine with their ease of use, a large selection of drying programmes, as well as a large capacity. In addition, Bosch models are slightly cheaper than Siemens models.
Siemens Simens heat pump dryers, on the other hand, are particularly quiet and offer a wide range of programmes and are easy to operate. Furthermore, many of the Siemens models can be connected to the waste water pipe with a hose, so that emptying the condensation tank is no longer necessary.

Decision: What types of Bosch heat pump dryers are there and which is the right one for you?

If you have decided to buy a Bosch heat pump dryer, there are two basic types of this product:

    • Bosch AutoClean dryer
    • Bosch dryers with Smart Dry function

It all depends on your personal preferences which of these models will suit you more and support you in your household management as best as possible. To make this decision as easy as possible for you, we have listed some of the advantages and disadvantages of these Bosch appliances in the following sections:

What makes a Bosch AutoClean dryer special and what are its advantages and disadvantages?

The AutoClean function of Bosch heat pump dryers is mainly characterised by the fact that you no longer have to clean the lint filter with every drying cycle, but at most with every 20th drying cycle. The condenser also cleans itself. Since dryers lose their energy efficiency over time if they are not cleaned properly, this function is definitely advantageous, as it keeps energy consumption permanently low However, you should bear in mind that this convenient function also goes hand in hand with significantly higher dryer prices

  • Very convenient
  • Helps keep energy consumption continuously low
  • Less work
  • Usually more expensive
  • Due to increased technical features often more susceptible to repairs

What distinguishes a dryer with Smart Dry function from Bosch and what are its advantages and disadvantages?

Bosch dryers equipped with the Smart Dry function make your work easier by setting the drying programme automatically and individually by the dryer itself. Through "Home Connect", your Bosch washing machine and dryer communicate with each other. The washing machine then sends information such as the load weight and the degree of residual moisture to the dryer, which can then select the perfect programme and treat your laundry as best as possible A disadvantage here could also be the higher price compared to simpler models. However, it is also a prerequisite that your washing machine must also be from Bosch and equipped with a Home Connect function

  • Significantly higher comfort due to reduced workload
  • drying programme is always perfectly selected by the dryer
  • prevention of incorrect settings
  • Usually relatively high price
  • Requires a washing machine that is also equipped with the Home Connect function
  • Technical misadjustments cannot be completely ruled out

Buying criteria: You can use these factors to compare and evaluate Bosch heat pump dryers

In the following, we will show you which aspects you can use to decide between the many possible Bosch dryers. The criteria you can use to compare the dryers with each other include:

In the following sections, we will show you in more detail what the individual criteria are.

Power consumption

Dryers and washing machines are among the biggest power guzzlers in the household.

As already mentioned in previous sections, the electricity consumption of heat pump dryers is significantly lower compared to other types of models. This is due to the further development of the components. Instead of a condenser, an energy exchanger is now used, which in turn uses the heat extracted during cooling to dry the remaining laundry In general, you should always pay attention to the energy efficiency class when buying a dryer, because the less or more your dryer will consume. In the following table we have listed a small comparison of the energy efficiency of different dryer models:

Type Electricity consumption
Heat pump dryer approx. 1.3 - 2 kWh per Drying cycle
Condensation dryer approx. 3.5 - 4.4 kWh per drying cycle
Exhaust air dryer approx. 3.25 to 3.9 kWh per drying cycle

Bosch heat-pump dryers are no lower than A+ in the energy efficiency class, because Bosch attaches great importance to good quality and technical progress.

Self-cleaning condenser

A self-cleaning condenser can definitely make your everyday life easier and is therefore one of the purchase criteria you should definitely keep an eye out for when buying a Bosch dryer. Bosch puts a lot of emphasis on efficient operation, as well as gentle and perfect drying of your clothes. A self-cleaning condenser relieves you of the task of having to clean the condenser or heat exchanger of your heat pump dryer at regular intervals. If this is not done, the heat exchanger can become clogged over time, which in the worst case scenario will make your dryer unusable and you will have to buy a new one. If you don't like to do this or forget to do it, it may be a good idea to buy a Bosch heat pump dryer with a self-cleaning condenser to get the most out of your dryer for as long as possible.


The capacity of a heat pump dryer indicates the maximum number of kilos of laundry you can dry during one drying cycle. Especially if you have a large family or a lot of laundry in general, you should look for the highest possible capacity when buying a dryer.

In general, the capacity of various Bosch heat pump dryers ranges from 7 kg to 9 kg.

This is also an aspect that should not be neglected when it comes to energy consumption. After all, a very good energy efficiency rating is not much use if the capacity is too small and the dryer has to run twice as often as one with a lower energy efficiency rating.

Drying time

The drying time of your Bosch dryer always depends on the particular appliance and its technical features. For the standard cotton programme, the average drying time is between 122 and 199 minutes. Generally speaking, it is better to have a dryer with the shortest possible drying time, especially if you have a large household. However, it often depends on the programme you have chosen to dry your laundry, as well as the load. Compared to other dryer models (for example Bosch condensation dryers), Bosch heat pump dryers take a little longer on average, but are relatively more energy efficient.

The volume can be an important factor in the purchase decision, as the dryer should not be too loud, especially in relatively small flats. This criterion can also vary from appliance to appliance and you should think carefully beforehand about where you want to place your Bosch heat pump dryer and how loud it can be accordingly.

The noise level of Bosch dryers can vary from around 59 to 65 decibels and is usually a little lower with heat pump dryers than with condensation or exhaust air dryers.

So if you have a small flat, and the dryer may even be placed in the bathroom or kitchen, it might be worthwhile to go for a rather quiet heat pump dryer.

Number of special programmes

The more programmes your Bosch heat pump dryer has, the more individual and better your laundry can be treated. After all, there is almost nothing worse than taking your favourite top out of the dryer and finding that it has shrunk completely. That's why it's even more essential when buying your new Bosch dryer to make sure that it has all the programmes you need for your everyday laundry. Generally, the more special programmes your Bosch dryer has, the more expensive it can be. Meanwhile, the various programmes are no longer limited to the degree of drying, but offer a variety of other options. For example, there are settings depending on the material, e.g. down programmes, programmes for particularly sensitive fabrics or wool programmes. But also special settings to get the laundry out of your heat pump dryer as crease-free as possible can make your life much easier.

Facts worth knowing about Bosch dryers

What is the best way to clean a Bosch heat pump dryer?

It is particularly important to clean your Bosch heat pump dryer regularly, as this can have a significant impact on the lifespan of your appliance. If you want to enjoy the benefits of your dryer for as long as possible, you should pay attention to some of the following points. There are several parts of your Bosch dryer that need to be cleaned at regular intervals, unless they are equipped with one of the self-cleaning functions:

      1. The housing: If necessary, you should clean it with a soft cloth and a little washing-up liquid. You should also remember to remove any lint that may collect on the back of the dryer.
      2. The lint filter: This is located inside your heat pump dryer and should be cleaned after every use. Otherwise, the performance of the dryer can lose efficiency and the dryer may not be ready for use at all.
      3. The condensate container: This should also be removed from the dryer after each drying cycle and emptied over a sink.

More detailed cleaning instructions can also be found in the operating instructions of your Bosch heat pump dryer. For more specific advice, you can of course also contact Bosch customer service.

Can Bosch heat pump dryers be connected to a waste water hose?

In principle, it is possible to connect a Bosch heat pump dryer to the water system with a waste water hose. This eliminates the need to empty the condensation tank after each drying cycle. However, this also involves the risk of water getting into the interior of the dryer and the connection is relatively costly. In addition, such a connection cannot be installed everywhere. So you should think twice before spending more money on a heat pump dryer and take the risk. It is probably easier to empty the condensation tank after use with a simple movement of the hand.
