What Is A Heat Pump Dryer?

A heat pump dryer is an energy-efficient appliance that uses a refrigeration cycle to remove moisture from clothing and textiles.

A heat pump dryer is a type of condenser clothes dryer that uses a heat pump to heat the air and absorb moisture from the clothes. The refrigerant in a heat pump draws the hot air from inside the drum, compresses it, and then pushes it through a small coil filled with coolant, such as Freon gas or ammonia-water mixture.

As this process takes place, warm moist air is converted to cool dry air due to latent energy conversion. This repetitious cycle ultimately results in clothing being dried without producing any waste water.

Heat pump dryers are more efficient than traditional condenser tumble dryers, since they typically use up to 60 percent less electricity for drying cycles compared to traditional machines.

How Does a Heat Pump Dryer Work?

Heat pump dryers work by recycling warm air instead of exhausting it to the outside. 

Heat is produced using a refrigeration cycle, in which a compressor pumps refrigerant vapour through the system and transfers it into a condenser coil to release stored heat.

At this point, the air is at high temperature and low pressure. This hot air can then be used to first preheat the drum before drying clothes in the same circulation loop.

Differences Of Heat Pump Dryer From Traditional Dryers

When comparing heat pump dryers and traditional dryers, it is essential to understand the key differences in their features, which contribute to the energy efficiency and performance of each type. The following table highlights these differences for a better understanding.

The cost savings from using a heat pump dryer extend beyond its reduced environmental impact as well.

Gentle On Clothes

Heat pump dryers are a great choice for anyone who cares about the condition and lifespan of their clothes. These use low temperatures to evaporate the water from garments without the need for direct heat.

This helps to prevent clothing items from damaging or shrinking as they would with other models due to intense heat. 

Heat pump dryers also work more rapidly which means that garments get dried faster and will last longer because they’re not exposed to high temperatures over long periods of time.

Longer Life Span

Heat pump dryers have a distinct advantage when it comes to lifespan. On average, they can last up to 15-20 years; this is significantly longer than the 7–10 year span of traditional dryers and about two times as effective.

During their longer life spans, these machines save you money on replacements and utility costs. The incredibly long lifespan of heat pump dryer is a result of its gentler drying process which often requires less maintenance over time compared to traditional models that are prone to wear and tear from frequent use.

In addition, routine repair and maintenance will also help keep this kind of appliance running at optimal efficiency such as checking the filter every few months or emptying out water tanks after each load depending on your model – in order to get the most benefit from its energy saving features.


Heat pump dryers offer several advantages over traditional vented electric dryers. On top of using far less energy and reducing bills, they also significantly reduce the operating costs.

The long-term savings associated with heat pump drying can add up quickly. ENERGY STAR certified models offer customers a guaranteed way to see these savings each month in reduced electricity charges.

Additionally, their upfront cost is generally higher than that of conventional machines (ranging from $800 -$1400), but longer life spans help offset this initial investment.

Consumers will likely save money in repair or replacement costs as well due to their highly efficient designs and durability.


Heat pump dryers offer a very convenient option for drying your laundry. By employing the same air warmed, cooled, and condensed within a self-contained system without the need of external vents, they provide homeowners with a ventless drying solution that is energy efficient and easy to install.

Additionally, heat pump dryers are designed to be connected directly to a damp drain hose so you don’t have to worry about dumping out any water during each cycle or manually piping steam away from the machine.

As such, these modern appliances can help reduce some of the upkeep hassle of traditional units by minimizing both installation costs and maintenance time. 

On top of this convenience factor lies an even bigger added benefit that is it saves more energy when compared with more traditional models due to their unique design efficiency (specifically inverter technology).

Is A Heat Pump Dryer Right For You?

When considering whether a heat pump dryer is the right fit for your household, it’s important to evaluate factors such as availability of space, budget, and frequency of use.

Factors To Consider

When deciding whether or not to invest in a heat pump dryer, it is important to consider several factors. These include 

  • household size, 
  • available space for installation,
  • budget and 
  • the frequency of use.

Household Size: 

When deciding if a heat pump dryer is the right choice for your home, household size and frequency of use are important factors to consider. With any laundry device, it’s essential to choose one that meets the needs of your family.

A large-capacity dryer can easily handle many loads at once or hold a few extra items you want dried faster than normal cycle times. However, drying too many items in one load will cause clothes to come out less fluffy and take longer to dry if multiple cycles are needed.

Conversely, if the household dries only a handful of small items on rare occasions, then a single-load model may be enough, although larger capacity models offer more energy savings potential with each wash over time.

It’s also important to understand that while heat pump dryers have lower operating costs than regular vented dryers (potential savings of up to 50%, according to nytimes.com), they can take three times as long when compared with traditional electric vented or gas condenser varieties (maximum cycle time being typically 15 minutes).

Additionally, like condenser dryers there is an additional requirement for drainage during operation.

Available Space: 

The size of your laundry room could also determine which type of dryer you choose as heat pump models are generally bulkier than traditional vented dryers and need dedicated spaces due to their bigger air filter that needs regular maintenance checks every couple years or depending on usage rate.


Most people look at price first when making decisions like this one, while initial costs should certainly play into the decision.

Electric bills should also factor in consideration since electric-powered appliances typically cost more over time than gas-powered ones due to their higher level of energy consumption. 

Therefore, those with tighter budgets may find a conventional or condenser model more suitable for their particular situation, where the difference in monthly electric bills would still save them money despite being a lower-powered machine compared to what’s offered by modern Heat Pump Dryers.

LG’s upcoming 8Kg True Steam titanium printer/yearly cost warranty. True Steam technology offers a longer lifespan +10-year components corrosion warranty vs 7-year industry standard.

Frequency of Use: 

For occasional users who only do laundry once or twice weekly should probably opt for system that produces less steam i.e condensing style type vs fully fledged sleeveheat exchangers designed. 

Another defining point since its widely recognised fact after ~5-7years heavy use some parts inside compressor coil tubes become clogged or corroded leadingto faster deterioration rates accelerated by fluctuating environmental conditions.

Heat Pump Dryer And Water Drainage

Heat pump dryers use water from the laundry cycle along with heat to absorb moisture from clothes and then pump it out in the form of steam or condensate, reducing drying times.

How Heat Pump Dryers Use Water

Heat pump dryers work by recycling the hot air used to dry clothes, so they don’t require a direct water connection. Instead, they utilize an evaporator and condenser to remove moisture from the air during drying and exhaust it as steam or condensed water.

This means that heat pump dryers need to drain in order to operate, either through an external hose or a built-in collection system.

The advantage of this process is that much less energy is required than with traditional models which generate their own heat using gas burners or electric coils. By operating more efficiently, these models can save considerably on energy costs while still providing excellent drying quality.

Benefits Of Heat Pump Dryer’s Water Drainage

  • Heat pump dryers use evaporative cooling to condense moisture into water, and then drain it away through a tube. 
  • This helps reduce limescale build-up in the machine, which can affect efficiency if left unattended. The drained water may be connected to a household plumbing system or collected in a container for up to two cycles.
  • The advantages of heat pump dryer draining water are vast as it reduces energy bills as well decreasing environmental impact.
  • With such machines being gentler on clothes than their electric counterparts, and lasting much longer due to fewer clogging issues of parts, there is also an effective cost-saving element attached as replacing worn down components becomes less frequent over time.
  • Additionally, ventless heat pumps offer more convenience since they do not require external air ducts.

Tips For Maintaining Your Heat Pump Dryer

  1. Clean the lint filter before each drying cycle to ensure better performance and energy efficiency.
  2. Periodically drain the water from your heat pump dryer in order to reduce limescale buildup, which can lower efficiency. This should be done once a month or as often as advised by the manufacturer’s instructions.
  3. To keep your dryer functioning properly, make sure you clean it regularly. At least every 6 months using a vacuum cleaner attachment or an appropriate cleaning brush set. Be sure to clean all hard-to reach areas like behind removable panels, near vents and around pipes inside the machine.
  4. Regularly inspect venting ducts for blockages that could impact air circulation within the appliance and effect drying results.
  5. Check them at least twice per year depending on usage frequency.
  6. Maintain adequate airflow away from heater components so they don’t overheat. This will help avoid potential fire hazards emanating from clothes debris build up on surfaces of inner walls/surfaces of frame work/around condenser (coolant) coils among other likely locations leading potentially excessive temperature rise due to heating up of these items when moving with warm exhaust gasses.
  7. Use only mild detergents recommended by manufacturers in their user manuals when washing fabrics intended for use with heat pumps.
  8. Don’t use certain aggressive chemicals that may interfere with optimal working conditions or greater than expected wear & tear thresholds affecting life time expectancy for such appliances eventually impacting overall operational feasibility & economics.
