Energy consumption heat pump dryer

A heat pump dryer consumes the following energy: per drying cycle it consumes between 0,80 and 1,45 kWh. The consumption of a heat pump dryer amounts to approximately 100 to 170 kWh per year. If you convert this into euro, you will spend approximately €24,- to €40,- on energy costs annually.

What does a heat pump dryer consume

A heat pump dryer has an energy label of A or higher, while a condenser dryer has an energy label of B or C. The difference in energy consumption can be quite substantial, especially after several years of use. We give you an example of the difference: the annual energy costs of a condenser dryer are on average €115, while the annual energy costs of a heat pump dryer are €40. This covers the same usage, about 220 drying cycles per year. Heat pump dryer uses 1.25 kWh per wash, which is 275 kWh per year.

What does a heat pump dryer save

What exactly is the advantage of a heat pump dryer? And when is a heat pump dryer cost effective? Is a heat pump dryer really more economical than a condenser dryer? The savings of a heat pump dryer depend on the type of heat pump dryer and the dryer you compare it to. The first example concerns a new condenser dryer and a new heat pump dryer: the new condenser dryer uses on average €115 per year, while the new heat pump dryer only uses €40 per year. With savings of €75 per year, this can add up to €750 after 10 years. The lifetime of a new heat pump dryer is longer than 10 years, so the savings will be even higher.

Calculation example 1

Calculation example 2 consists of an old washer dryer from 2000 that uses about 3,95 kWh per wash cycle, and a new heat pump dryer that uses a maximum of 1,25 kWh. The cost of a drying cycle is then €0,87 versus €0,19. The difference is €0,68. If you assume that you do 220 drying cycles in a year, the difference is €150 per year. A heat pump dryer can therefore make a significant difference in energy costs, and be a smart purchase for that reason.

  • Condensation dryers cost €115 per year
  • Heat pump dryers cost €40 per year
  • Save €75 per year

Calculation example 2

The heat pump dryer has a different technology, which heats the air by using refrigerant to remove the cold condensation from the air. In doing so, the heat pump dryer reuses its air, resulting in less energy consumption and a more favourable energy label. Most condenser dryers have a poor energy label and may therefore no longer be sold. On the current market, only new dryers with an energy label of at least C may be sold, while some major suppliers have already chosen to no longer offer these and only sell from energy label B onwards. A heat pump dryer has a better energy label and even has environmentally friendly models. Models can call themselves environmentally friendly with an energy label of at least A++. All in all, the difference in energy consumption and thus energy costs is well worth it. And any higher purchase cost of a heat pump dryer will pay for itself over the lifetime of the heat pump dryer.

  • Condensylvanian dryer costs €0.87 per drying cycle
  • This is the most expensive heat pump dryer.Heat pump dryer costs €0.19 per drying cycle
  • Save €0.68 per drying cycle

Energy efficient drying

Besides buying an energy efficient heat pump dryer, there is a lot you can do to reduce the energy consumption of your heat pump dryer. The impact you have is greater than you think. It offers three major advantages: lower energy costs, less environmental impact and a longer life for the dryer. The lifespan is partly determined by the number of washes. If you reduce the number of washes per period, you will see that the dryer will last longer! We will explain how you can have an impact on your energy consumption with a few handy tips. The higher the spin speed, the drier the wash will be. It then needs less energy from the heat pump dryer to dry completely. Now you probably think: but higher rpm’s also cost more energy?   That’s right. However, the energy consumption of a washing machine is often lower than that of a heat pump dryer. This might not be the case, so check the energy label of the washing machine and heat pump dryer before you apply this tip. If you have a new heat pump dryer with an A+++-10% energy label and an old used washer with an F energy label, this tip is not very useful to you. In addition, this tip is only applicable for a heat pump dryer with a moisture sensor. If the heat pump dryer doesn’t have one, the dryer won’t notice that the clothes are already dry and won’t adjust the program accordingly. In this case, you will not reap the benefits of the higher rpm and it is not worth it.

Select ‘Automatic’

The ‘Automatic’ program is available if the dryer has a moisture sensor. The moisture sensor then determines the length of the program, so it will never run longer than necessary. This is more efficient than letting the heat pump dryer dry for too long.

Clean the condenser

This point is very important. This is because a dirty condenser equals higher energy consumption. The user manual will tell you exactly how to clean the condenser. Some heat pump dryers have a self-cleaning condenser or an indicator that tells you when to change it. Make sure you don’t ignore this if the heat pump dryer won’t do it on its own.

Clean the filters

Another important cleaning job is the filter. If the filter is dirty, the heat pump dryer will not work as well. This not only makes it less likely to break down, but it automatically uses more energy. Especially in the warmer summer months, but also for smaller loads, a clothesline or rack can be a great solution. The less you use the heat pump dryer, the less energy you use and the longer the heat pump dryer will last. Simply put: be aware of the drying loads. Is it really necessary, or can this load easily be dried on a clothesline?

Make sure the heat pump dryer is right for you

The size of your household and the amount of laundry determines the fill weight. A fill weight varies from 6 to 9 kilograms. The more people there are, the larger the load. A 6kg capacity is suitable for 1 to 2 people. If you have a household with 3 to 4 people, a 7 to 8 kg capacity is better. For a larger household (5 or more people), choose a 9 kg. This is because an empty dryer is a waste of energy. The heat pump dryer will use the energy needed to run a large drum. Too much laundry for a small dryer is also not energy friendly, you have to switch the dryer on more often, which causes the heat pump dryer to run out of steam sooner, and you clearly use more energy.
