Does a Heat Pump Dryer Need Plumbing?


With the advancement of technology, heat pump dryers have gained popularity in recent years due to their efficiency and environmental friendliness. Unlike traditional dryers, heat pump dryers use innovative technology to recycle heat, reducing energy consumption and saving you money in the long run. However, one common question that arises is whether a heat pump dryer requires plumbing. In this article, we will explore the workings of a heat pump dryer and determine whether it needs plumbing or not.

Understanding the Heat Pump Dryer:

1. How does a heat pump dryer work?

A heat pump dryer operates differently than a conventional vented dryer. Instead of expelling moist air outside, it recirculates and condenses the warm air, extracting moisture as it cools down. This process is facilitated by a heat exchanger and a refrigeration system within the dryer. The heat exchanger extracts the warm air from the drum and passes it through the refrigerant-filled coils.

2. Plumbing system in a typical heat pump dryer:

Contrary to popular belief, a heat pump dryer does not require a dedicated plumbing connection. It has a self-contained internal system that collects the condensed water, also known as the condensate, during the drying process. This water is stored within a reservoir or a collection tank conveniently located near the front of the dryer. The condensed water can then be emptied manually or pumped out using separate plumbing, if desired.

Installation and Convenience:

3. Simple installation:

Since a heat pump dryer does not require any plumbing connections, its installation is relatively easy and hassle-free. You only need to find an appropriate location, preferably near an electrical outlet, and ensure proper ventilation for the dryer. Unlike vented dryers that need ductwork and exhaust vents, a heat pump dryer can be placed in various areas within your home.

4. Portability and flexibility:

The absence of plumbing allows for enhanced portability and flexibility. You can move the heat pump dryer around different rooms and even take it with you when moving houses, as long as there is an electrical outlet available. This makes it a convenient option for those who might have changing living arrangements or limited space for a fixed dryer setup.

Maintenance and Energy Efficiency:

5. Easy maintenance:

Heat pump dryers require minimal maintenance. Regular cleaning of the filters and reservoir is necessary to ensure optimal performance. The filters prevent lint from clogging the heat exchanger, while the condensate reservoir needs periodic emptying. Some models are equipped with self-cleaning functionality, further reducing maintenance tasks.

6. Energy efficiency benefits:

Heat pump dryers are renowned for their energy-efficient operation. Compared to traditional vented dryers, they use up to 50% less energy, resulting in significant cost savings over time. The absence of plumbing requirements contributes to this efficiency by eliminating the need for continuous water supply or drainage. Heat pump dryers also have sensors that monitor the moisture content, automatically adjusting the drying time accordingly.

Considerations and Alternate Options:

7. Limited drying capacity:

One factor to consider when purchasing a heat pump dryer is its drying capacity. The condensate reservoir typically has a lower capacity compared to the volume of laundry that can be dried in one cycle. Therefore, if you frequently dry large loads of laundry or have a large household, you might need to empty the reservoir more frequently.

8. Heat pump hybrid dryers:

For those who prefer the benefits of a heat pump dryer but require a plumbing connection for ease of use, heat pump hybrid dryers are a viable alternative. These models combine the convenience of a heat pump dryer with the option to connect them to the plumbing system for automatic water drainage. Heat pump hybrid dryers offer the best of both worlds and can be a suitable choice for those who desire a plumbing connection.


In summary, a heat pump dryer does not require plumbing connections for its basic operation. The condensed water is collected in a reservoir or tank located within the dryer, which can be emptied manually or pumped out separately. The absence of plumbing makes installation and relocation more straightforward, providing flexibility and convenience. As heat pump dryers continue to grow in popularity, they contribute to energy savings and environmental preservation, making them an excellent choice for modern households.
