What Is the Difference Between Vented and Heat Pump Dryers?


Laundry is an integral part of our daily lives, and having an efficient and reliable dryer makes the process much more convenient. When it comes to selecting a dryer, two popular options are vented and heat pump dryers. Both types have their advantages and disadvantages, so it's essential to understand the differences between them. In this article, we will delve into the working mechanisms, energy efficiency, drying performance, installation requirements, and cost considerations of vented and heat pump dryers. By the end, you'll be equipped with the knowledge to make an informed decision about which type of dryer is best suited for your needs.

Working Mechanisms:

Vented Dryers:

Vented dryers are the more traditional type and have been widely used for many years. These dryers work by drawing in ambient air and heating it using an electric heating element or a gas burner. The hot air is then circulated through the drum to dry the clothes. Moisture is expelled from the dryer through a vent that is connected to an external wall or window. This expelled air usually carries lint and can be quite humid, requiring proper ventilation.

Heat Pump Dryers:

On the other hand, heat pump dryers are a more recent technology that has gained popularity due to their superior energy efficiency. These dryers work by using a heat pump system rather than direct heating elements. A heat pump draws in ambient air and heats it using a refrigeration cycle, similar to how a refrigerator works. The heated air is then circulated through the drum to dry the clothes. The moisture extracted from the clothes is condensed and collected in a reservoir or drained out, resulting in significantly reduced energy consumption.

Energy Efficiency:

Vented Dryers:

Vented dryers are known to be less energy-efficient compared to heat pump dryers. Since the heat is produced directly using electric or gas heating elements, there is a significant amount of energy lost through the venting process. This loss of energy not only impacts the environment but also contributes to higher electricity or gas bills. However, vented dryers are generally less expensive to purchase upfront.

Heat Pump Dryers:

Heat pump dryers are the epitome of energy efficiency in the world of clothes drying. The heat pump technology allows these dryers to use up to 50% less energy compared to vented dryers. The recycling of heat within the system greatly reduces energy wastage. Although heat pump dryers may have a higher initial cost, the long-term energy savings often justify the investment.

Drying Performance:

Vented Dryers:

Vented dryers are known for their fast drying performance. The high heat they generate helps to quickly evaporate moisture from the clothes, resulting in shorter drying times. However, this high heat can be harsh on some fabrics, leading to potential damage or shrinkage if not used with caution. It is essential to use temperature and drying options appropriately to prevent such issues.

Heat Pump Dryers:

Heat pump dryers generally have a slower drying performance compared to vented dryers. Since they operate with lower temperatures to achieve energy efficiency, the drying process can take longer. However, heat pump dryers are much gentler on clothes, making them ideal for delicate fabrics that are prone to damage. Additionally, these dryers offer a variety of drying options and sensor technologies to ensure optimal drying results for different types of fabrics.

Installation Requirements:

Vented Dryers:

Installing a vented dryer involves routing a vent pipe to the exterior of the house. This vent pipe allows hot, moist air to escape. The distance and complexity of the venting system depend on the dryer's location and the layout of the house. Proper ventilation is crucial to prevent the build-up of moisture and improve the efficiency of the dryer. It's important to note that vented dryers may not be suitable for apartments or spaces without external venting options.

Heat Pump Dryers:

Heat pump dryers do not require external venting, making them highly versatile in terms of installation. Instead of venting out hot air, these dryers extract moisture from the clothes and condense it into water. This condensed water can be collected in an internal reservoir or drained out directly. The absence of external venting makes heat pump dryers suitable for a wide range of living spaces, including apartments and condominiums.

Cost Considerations:

Vented Dryers:

Vented dryers are generally less expensive to purchase upfront compared to heat pump dryers. However, the higher energy consumption can result in higher electricity or gas bills over time. If you have a limited budget or drying performance is the primary concern, a vented dryer might be the right choice for you.

Heat Pump Dryers:

Heat pump dryers may have a higher initial cost, but they offer significant savings in energy consumption over time. These dryers are more suitable for those looking for long-term savings and sustainable appliances. If you prioritize energy efficiency and have a higher budget, investing in a heat pump dryer can pay off in the long run.


In conclusion, both vented and heat pump dryers have their own strengths and weaknesses. Vented dryers offer faster drying times and are generally more affordable upfront, but they are less energy-efficient and require proper ventilation. On the other hand, heat pump dryers are highly energy-efficient, gentler on clothes, and suitable for various installation scenarios, but they have a slower drying performance and a higher initial cost. Ultimately, the choice between a vented and a heat pump dryer depends on your specific needs, budget, and space requirements. Consider these factors carefully to make an informed decision that aligns with your laundry preferences and sustainability goals.
