Tumble dryer: Types, Benefits, & Problems

Tumble dryer: Types, Benefits, & Problems

In our previous article we looked at the washing machine in detail, focusing on what it is, its uses and common problems. One major drawback or feature which lacks in washing machines is the ability to dry clothes. Line drying though effective presents its own set of challenges, for instance during the rainy season, line drying won’t work.

This drawback necessitated the invention of another type of machine to dry clothes after they are done in the washing machine. Like its use suggests the machine is called a tumble dryer and it dries clothes faster and more efficiently without any hassles. 

In this article we are going to explore the features of the tumble dryer, and learn how to troubleshoot some of the common problems which can be encountered when using it.

Tumble Dryer

Also known as a clothes dryer, is a powered household appliance that is used to remove moisture from a load of clothing, bedding and other textiles, usually shortly after they are washed in a washing machine

All tumble dryers operate on the same general principle. An electric motor rotates the drum filled with wet clothes whilst simultaneously driving the fan which circulates hot air through the drum. A heater heats the air, and a thermostat maintains the correct temperature.

Let’s take a look at different types of tumble dryers.

Condenser tumble dryer

Condenser tumble dryers remove moisture from your clothes and store it in a removable tank. This kind of dryer is ideal if you can’t vent the moisture outside using a hose, but you’ll need to empty the tank after each cycle ends.

The main benefit of a condenser dryer is that it can be installed anywhere and doesn’t need to be located next to a door or window, so if you are looking for convenience perhaps this is the one for you. The downside is that you will have to regularly empty the reservoir of extracted water.

Heat pump tumble dryer

Heat pump tumble dryers recycle hot air created inside the drum to dry clothes, which makes them really efficient. This saves a lot more energy, but programmes may take a little longer to dry laundry.

Using a lower temperature to dry the load, a heat pump tumble dryer offers better protection for your clothes as higher temperatures can damage certain fabrics. Whilst it takes slightly longer to dry a load compared to a standard condenser dryer, it can help you significantly reduce your energy consumption

Vented tumble dryer

Vented tumble dryers remove moisture from your clothes and feed it outside through a vent. They come with a long hose to help you do this, but you may need to get it installed by a professional if you want to vent the moisture out through a wall. While vented models tend to be the cheapest on the market, they’re also the least energy efficient.

Vented dryers are, on average, the fastest drying option. However, like condenser dryers, vented dryers aren’t very energy efficient

So the big question is which tumble dryer is the best? This depends with the situation of end user as everyone has different needs, but generally it can be said that the heat pump tumble dryer is the most energy efficient type of tumble dryers and no venting is needed.

Heat pump dryers don’t create hot air or moisture so they’re perfect for apartments. They even use less than half the energy of a vented or condenser dryer, so the higher purchase price is recouped on power bill savings over the dryer’s lifetime.

Tumble dryers have earned a top post as one of the favorite household appliances and are especially a godsend to large families which go through a lot of laundry every week and for people with limited line drying space, let’s look at some of the benefits of tumble dryers in detail.
