How a heat pump dryer works
There are several types of clothes dryers available, the heat pump dryer consumes the least energy of these and is therefore a very popular choice. Would you like to know more about the heat pump dryer and are you curious about how a heat pump dryer dries? You can read exactly how a heat pump dryer works here.
How a heat pump dryer works
Unlike conventional dryers, the heat pump dryer doesn’t use a heating element to dry your laundry. Instead, it uses a heat pump in conjunction with a refrigerant. The heat pump converts the refrigerant, which is in liquid form, into gas form. This releases warm air, which heats the drum and your laundry. When your laundry is dried, a moist warm air is released. That warm air is cooled by the refrigerant, creating condensation. The condenser captures this moisture.
Heat pump dryers can get rid of that condensation in 2 different ways:
- It is collected in a water reservoir. This reservoir is built into the dryer and must be manually emptied into the sink after each drying program.
- If your heat pump dryer is connected to the water drain with a hose, the moisture is drained directly. You do not have to empty the tank, but it is a requirement that you have a drain in the laundry room.
If you choose to connect to the water drain you will have little maintenance on the dryer. Just keep in mind that once every few months you will need to rinse the condenser clean – unless your new clothes dryer has a self-cleaning condenser. This means you don’t have to.
Because the heat pump dryer uses a heat pump and a refrigerant, you maintain a lower temperature. By drying at a low drying temperature, a heat pump dryer uses less electricity, and your laundry lasts longer.
The difference with the condenser dryer
Today, most clothes dryers sold are heat pump dryers. Condenser dryers are in second place. The condenser dryer uses a heating element to heat the drum and dry the laundry. The condenser dryer’s heating element uses a lot of electricity, which increases energy costs. An energy-efficient condenser dryer is therefore difficult to find. To be considered “energy efficient,” a clothes dryer must be at least energy class A++. Most condenser dryers have energy class B. In comparison; most heat pump dryers have energy class A++ or A+++ and are therefore a lot more economical than a regular condenser dryer.
With a condenser dryer, as with heat pump dryers, you often have the choice of whether you want the condensation to drain through the water outlet or collect it in a tank.
In addition, the condenser dryer uses a higher drying temperature than the heat pump dryer. As a result, your laundry will dry faster in a condenser dryer, but is more likely to wear and shrink. Drying at a lower temperature will help your clothes last longer. The low temperature of a heat pump dryer is therefore better for your laundry.
The vended dryer uses even more energy per drying cycle than the condenser dryer. Because this type of dryer uses so much energy, we don’t recommend purchasing one. The vended dryer also dries with a heating element at a high temperature.
However, with this type of clothes dryer, the moisture cannot be collected in a water tank, nor can it be connected directly to the water drain. Vended dryers use an exhaust hose to lead the moist air out through a window or a hole in the wall.
Conclusion; comparing the different clothes dryers
We are big fans of heat pump dryers because they have the lowest energy consumption. In purchase, the heat pump dryer is more expensive than the rest, but because they are so energy efficient drying is often the most economical choice. An energy-efficient dryer is not only better for the environment, but also for your wallet. These devices are often more expensive to buy, but because they keep your energy costs low, you can actually save money with them.
A heat pump dryer with energy class A+++ consumes so little electricity that it can save you up to 75 euros per year. Over the lifetime of the dryer (average 12 years) that can add up to 900 euros. For this reason, an investment in a heat pump dryer is definitely worthwhile.
Of course, you ultimately decide what is the right dryer for you. Perhaps you want your dryer to be ready quickly and not cost too much – in which case a regular condenser dryer is probably a better choice. Do you have questions or need advice? Don’t hesitate to contact us or your supplier!
