Condensers and heat pumps are among the most common options for dryer technology.

The amount of energy the dryer consumes is crucial to predicting its long-term costs.

But which is more efficient, a condenser or a heat pump dryer? I’ll discuss this and more throughout this article.

A heat pump dryer is better than a condenser dryer based on energy efficiency. Although these have similar systems, the closed loop system of a heat pump allows the recycling of hot air. This economy of action lessens energy consumption—whereas condenser dryers expel hot air, leading to energy loss.

Through this article, I’ll help you reach a practical decision regarding dryers.

So, keep reading as I discuss why heat pump dryers are more energy efficient and the pros and cons of each technology.

Appliances like dryers consume energy to function. This energy does not only affect us environmentally; it also impacts us financially.

Thus, considering the energy efficiency of a dryer is crucial to making an informed decision.

If you compare a condenser and heat pump dryer, the latter is more energy efficient. Various sources estimate that the energy consumed by a heat pump dryer is around half or less than half of that of a condenser dryer.

But why is there such a drastic energy consumption difference between the two technologies? The closed loop system of a heat pump dryer sets these drying systems apart from the alternative dryer systems.

Closed Loop System

Both condenser and heat pump dryers use hot air to collect moisture from clothes and dry them.

However, condenser dryers release hot air and humidity from the system as they operate, which is wasteful.

Heat pump dryers, on the other hand, use an evaporator to take the water from the hot air so that only the moisture is released. The hot air (with the moisture removed) is then recycled and used again to further the drying process.

This continuous cycling process is why the heat pump dryer system is called a closed loop. The hot air in use is recycled, which leads to less energy consumed or lost.

Automatic Sensors

Another feature in most heat pump dryers is the automatic sensor. These may also be called moisture sensors.

This technology allows dryers to stop the drying process without manual intervention once the clothes are dry. This automatic response saves energy because the appliance won’t have to keep functioning even when the clothes are dry already, which can happen with manual dryers.

This feature is also present in many condenser dryers, making both dryers more energy efficient than their manual counterparts.

Energy efficiency is an important topic, both for the environment and for your wallet. We’ve put together a free eBook guide that provides a range of ideas on making your home more energy efficient.

Although heat pump dryers are already pretty energy efficient, there are ways to make them more so.

You can take these steps for a more energy-efficient household:

  • Energy Certified Dryers. When purchasing a heat pump dryer, look for models that have energy efficiency certificates, like ENERGY STAR.
  • Energy-Efficient Washer. Using a washer and dryer that are both energy efficient (e.g., ENERGY STAR certified) will help cut long-term costs. 
  • Lowest Heat Setting. Using the lowest heat setting leads to less heat used; thus, less energy consumed.
  • Regular Maintenance. Making sure your dryer works well and has clean filters makes it more efficient and lasts longer.

Heat Pump Dryer vs. Condenser Dryer

Although I’ve established that heat pump dryers are more energy efficient than condenser dryers, that does not necessarily make them the best option for you and your lifestyle.

There are other factors to consider when deciding whether they are the most practical option for you.

Thus, to help you decide better, I’ve laid out the pros and cons of each dryer technology. Weigh these carefully to assess which is more efficient (overall) for you.

Heat Pump Dryer


  • Safer for clothes. The temperatures used by a heat pump dryer are much less than a condenser. Less heat is safer for clothes and avoids fabric damage.
  • Energy efficient. As I’ve discussed, this dryer’s closed-loop system and automatic sensors make it more energy efficient. The tips I’ve shared above may improve efficiency further.
  • Easy to install. This device does not need a vent, and you may install it in small spaces— which suits people living in apartments or small areas.


  • More time. Because it generates less heat than a condenser dryer, heat pump dryers take more time to dry clothes. However, that does not mean that it consumes more energy. 
  • Expensive. Up-front, you need to pay more for heat pump dryers than condensers. However, your long-term energy savings may offset the high short-term costs.
  • More noise. Condenser dryers produce less noise than heat pump dryers. However, heat pump dryers aren’t any noisier than non-condensing standard dryers.

Condenser Dryer


  • Less noise. Compared to heat pump technology, condenser pump dryers produce less noise, which is ideal for people living in shared spaces or sensitive to noise.
  • Less time. Because condensers use higher temperatures to function, they can dry clothes more quickly than other dryers. The downside is the potential damage it can do to the fabric.
  • Affordable. Most condensers bear affordable price tags, especially compared to heat pump dryers. However, you may have higher long-term running costs.
  • Large capacity. If you have a laundry business, a large family, or have a lot of clothes, a condenser dryer may better suit your needs because of its larger capacity. 


  • Need good ventilation. Because these dryers release more moisture, a sound ventilation system is required for condenser dryers.
  • Less energy-efficient. Because condenser dryers don’t recycle hot air, they are less energy-efficient. Thus, they may incur higher running or long-term costs.

Which Is More Cost Efficient: Condenser or a Heat Pump Dryer?

Ensuring your dryer is as efficient as possible not only saves energy but can save you a lot of money over time.

Given all I’ve discussed above, it’s hard to say which of the two technologies is more cost-efficient.

While heat pump dryers may be more practical regarding energy efficiency, they cost a lot to buy. The question is, can your long-term costs offset such high purchase expenses?

The cost-efficiency of a dryer depends on how often you would use it. If you use your dryer frequently, a heat pump dryer is worth the investment because of lower long-term (electricity and energy) costs.

However, if you only use your dryer sometimes, you may benefit more from a condenser. Although a condenser is less energy efficient, it is cheaper to buy than a heat pump dryer.

Average Weekly Running Costs

But how am I confident that heat pump dryers are cheaper in the long run? Let’s look at some figures based on credible data, such as this Dryers Buyer Guide from Energy Rating Australia.

According to the above source, these are the expected weekly running costs (in US dollar equivalent) of condenser and heat pump dryers:

 Weekly Running Costs (USD)
Condenser48.11 – 61.86
Heat Pump Dryer13.75 – 34.37

The figures in the table show a significant difference in the weekly running costs of condenser and heat pump dryers. This difference could save you a lot of money over the long term.

Another way to get a handle on your expected costs is to take the energy consumption rate of your device in kWh. Then, multiply it by the price you pay for electricity in kWh. You’ll then have an estimate of how much electricity your device uses and the running cost per hour.

Maintenance Costs

Maintenance costs are important to consider but often are not taken into account by people buying a new dryer.

Besides the weekly running costs, you also need to consider maintenance. A cheap machine that breaks down and needs repair more often would cost a lot to maintain.

It’s challenging to look for exact figures when it comes to maintenance. But you can weigh it using various factors, such as the brand’s known durability and the specific model’s features.

For instance, many heat pump dryers come with automatic sensors to keep them from overworking and take less effort to maintain. Compare that to a manual device that you might forget to turn off at times, leading to damage.

Consider Energy Efficient Condenser Dryers

It seems heat pump dryers have the edge over other dryer types in several areas. However, opting for a condenser doesn’t mean you can’t optimize your running and maintenance costs.

There are many new models of condenser dryers that have energy efficiency features. These include automatic sensors (as I’ve mentioned) and smartphone controls (so you can adjust or turn them off for efficiency).

The downside, though, of more energy-efficient condenser dryers is the cost. They’re usually more expensive than the usual condenser dryers because of their additional features.

Other Things To Consider When Buying Dryers

Besides energy efficiency, running costs, and price tags, these are some other things you have to consider when choosing your dryer:

  • Water drainage. Both dryers expel water, although heat pump dryers produce less water waste than condensers. Thus, you will have to choose from manual water tanks or automatic drain hoses. Automatic drains may be more convenient but are more costly.
  • Capacity. Both condenser and heat pump dryers have models with different abilities. Do not go for large-capacity dryers if you only have to dry a few clothes – it’s neither energy nor cost-efficient.
  • Other features. Pricier and newer models come with many features, which you might find convenient. These include anti-wrinkle settings, smartphone or remote control, and sensors. However, assess whether the additional costs these features bring are worth it for you.
  • Installation. Consider the space you have and what type of dryer will fit. For instance, you might prefer a wall-mounted dryer. However, most such devices are heat pump dryers only.
  • Dampener system. This extra feature would eliminate or reduce noise while the dryer is working.
  • Fast-drying. Many condenser dryers offer this feature, also called quick-dry. This option would hasten the drying process; however, it is less energy-efficient.

Final Thoughts

A dryer is a convenient appliance but also an investment.

When you purchase one, you need to consider factors like energy efficiency.

Heat pump dryers are generally more energy-conservative, but they may not be practical or efficient if you are not a frequent user.

Consider your lifestyle, expenses, and options when choosing a dryer to ensure you get the right type for your specific circumstances.
