Tumble dryers work by using a flow of hot air in the drum, the drum turns to toss the clothes and evenly distribute the heat therein. You can set a timer on most tumble dryers for the length of the process as you see fit while other might have a sensor which will limit the time of the process.
One major decision you wi ll have to make is choosing between a vented or condenser tumble dryer. The two perform the same job but get rid of the hot air and moisture from your clothes in a different way.
Vented Tumble Dryers
For the vented appliance the heated air carrying the moisture is pumped out of the unit altogether. This kind of appliance will feature a hose – usually around 2 metres worth – which will look much like the vent used in an extractor hood. You’ll need to arrange for the pipe to lead outside or risk pumping the warm air into your home. This can be done either by hanging it out of a nearby window or by having a permanent route out through a wall.
Condenser Tumble Dryers
The same process is involved for condenser tumble dryers as for vented ones; the drum tumbles the clothes and the hot air is is blown through to dry the clothes. The difference comes with how it deals with all the air and moisture internally. Using a large plastic container fitted into the unit, the appliance collects the moisture and drains it off to the container.
While this gives the appliance independence you will have to manually empty the container by removing it and pouring the moisture away. Some people have their appliance plumbed in to avoid this process and to aid drainage efficiency.
Condenser units are the more expensive of the two but clearly look a lot neater and don’t require additional works to be installed. Vented units on the other hand don’t seem to be making much progress in terms of developments with manufacturers focusing on condensers.
