All clothes dryers work by blowing heated air through your clothes to remove moisture, but there are several different types of dryers available which employ different technologies, features and levels of sophistication.
You'll need to consider:
- how often you'll be using your clothes dryer
- the kind of items you'll be using it for
- the available space and ventilation in your laundry
- the impact on your energy costs
- your environmental footprint.
Types of clothes dryers
What size do you need?
Will you be putting a full 8kg of washing into your dryer each time? Or just a couple of items?
Most people take the load out of the washer and put it straight in the dryer, which is why it's a good idea to match the capacity of your dryer to your washer. But we've found most people only wash around 3.5kg of laundry at a time, regardless of the size of their washing machine.
We recommend grabbing your laundry basket full of dry washing and jumping on the scales to see how much you actually wash each time to see what capacity you really need.
If you only want a small dryer, you may be restricted to a vented dryer – the more efficient heat pump dryers are generally all 7kg or greater.
Does capacity refer to the weight of wet or dry clothes?
It refers to dry clothes.
So, let's say you have an 8kg washing machine and fill it to capacity with 8kg of dry clothes. When you take the wet clothes out after the washing cycle, an 8kg capacity dryer is capable of drying that load – even though it's heavier now it's wet.
To prevent dripping walls and mould-ridden ceilings, you need to ensure the moist, hot air from the dryer is removed from your laundry efficiently.
Setting up your dryer near an open window or using an exhaust fan could do the job, but if this isn't possible then you're likely to need a venting kit. Some dryers come with one; for others it's an optional extra.
However, not all venting kits suit all situations. Discuss the installation with the sales staff to make sure you get what you need.
Remember, some dryers only have an exhaust vent at the front and can't be ducted. So if your laundry has poor ventilation, check that the model is vent-kit compatible before you buy.
Our clothes dryer reviews can tell you which of the dryers we've tested are front-vented and whether or not they can be ducted.
Wall-mountable or stackable dryers
Mounting your dryer on the wall or stacking it on top of a front-loading washing machine saves space.
- Some manufacturers only sell stacking kits as an optional extra, and they may only stack on their own brand of washing machine.
- Only vented dryers can be wall mounted – condenser and heat pump condenser dryers are too heavy and will need to be put on the floor or stacked on top of a washer.
Your lint filter needs to be cleaned regularly for your dryer to operate efficiently and to reduce the risk of fires, so it's helpful if the filter is at the front and easy to access.
Clean your clothes dryer's filter after each use to reduce the risk of fires.
The drum reverses the direction of tumbling at regular intervals for more even drying and to minimise tangling.
Some models come with a rack that can be mounted inside to hold items you don't want to tumble, such as gym shoes or delicates.
This claims to automatically detect when the load has dried.
Auto programs can take the guesswork out of clothes drying by switching your dryer off when it's done, saving energy and preventing the risk of damaging your clothes through over-drying.
In practice, they can be a little hit and miss depending on the size of the load you're drying.
This is a low-heat program designed for drying certain wool or wool-blend items of clothing.
Remember though that even with a woollens program, not all woollen garments can be safely dried in the dryer – read the garment care tag carefully and make sure it says that it's safe to do so.
Like a woollens program, a delicates program is a gentle, low temperature mode for drying delicate fabrics, though just as with wool, read the care instructions on the garment carefully. If it doesn't say it's safe to put in a dryer, you should air dry it instead.
Extra dry program
According to the Australian Standard, clothes dryers must be able to achieve a six percent or better moisture content, and if you're using your dryers' auto program, it will turn itself off once it reaches this point.
If you've used a dryer with an auto function though, you'll have noticed your clothes still feel a little damp. Why does your dryer stop at this point? For several reasons. It makes your clothes easier to iron, prevents over-drying and damaging delicate fabrics, and improves energy efficiency.
Even if you did get your clothes to zero percent moisture content (bone dry, in technical terms), they would rehydrate by absorbing moisture from the air.
But if you want your clothes extra dry, say, for sealing them up in a bag for winter, an extra dry function can remove a little bit more moisture. It gives you more flexibility, but isn't necessary for day to day use.
Delay time function
While it's not a good idea to leave laundry lying around wet for any length of time, there's a number of reasons why you might not want to start your dryer straight away.
A delay start, or delay time function allows you to set your dryer to start at a specific time, say, when everyone's gone to bed, to take advantage of peak solar electricity production in the middle of the day, or so the dryer finishes at a convenient time (though of course you should never run a dryer when you're out of the house due to the risk of fires).
When activated, the anti-crease function continues to gently tumble your clothes every so often after drying has finished, so creases don't settle in so readily.
Child lock controls
A great option if you have small, inquisitive children. Child lock controls prevent the dryer from starting unless a certain button combination is pressed – invaluable if you have curious little ones around with access to your laundry.
Auto-start and child safety
While shutting the dryer door and having it turn on automatically is convenient, the chance of having your small child climb into the dryer and shutting the door behind them is a horrible but very real possibility.
For this reason, we don't recommend dryers with this function for those with children or regular young visitors.
You can see which dryers have this functionality in our clothes dryer review, under the criteria 'Unit starts when door shuts'.
A vented clothes dryer will be one of the most energy intensive appliances in your home, using anywhere from 2.75kWh–9.25kWh per load.
For example, your energy costs 30 cents/kWh. Say a dryer uses 5kWh per load, and you use it three times a week (roughly 150 times a year) on average: 0.30 x 5 x 150 = your dryer is going to cost you $225 a year to run.
The good news is, a clothes dryer is one of the easiest to economise on when keeping an eye on the household budget – particularly given Australia's surfeit of sunlight.
If you're a heavy dryer user, consider buying a heat pump dryer as their running costs are much lower, but if you only use your dryer occasionally, your heat pump dryer's lower running costs may never amortise the higher purchase price, so a cheap vented dryer might be a better option.

Which is the most energy-efficient type of clothes dryer?
We compare the energy use of a vented, condenser and heat pump dryer.
|Type||Average energy used per load (kW)*||Average cycle time (minutes)*|
*Of models we've tested.
- Air dry your clothes wherever possible. Clothes dryers use a lot of energy to run, but sunlight is free.
- Keep your lint filter clean. A blocked lint filter makes it harder for air to circulate through your clothes, making your dryer less efficient and creating a fire hazard. You should clean your dryer's filter after every load.
- Use the highest spin speed on your washing machine, and if you're shopping for a new washing machine, look for one with a higher spin speed – this extracts more water, so your washing will take less time and energy to dry.
- Opt for an energy efficient dryer. If you can't avoid using your dryer all year round, opt for one with a high energy efficiency score or a heat pump condenser dryer. They cost more to buy but are cheaper to run so they can save you money in the long run. The more you use your dryer, the better an option this becomes.
- Open a window or use your home's ducting (if it's available). Venting moisture back into your laundry space just makes your dryer work harder to dry your clothes, costing you more. If you can't vent, consider a condenser or heat pump condenser dryer – they cost more to buy but are cheaper to run so they can save you money in the long run, and won't leave you with water dripping from the ceiling and down the walls.
- Be skeptical of dryer balls and other gimmicks. Some people will tell you that adding these to your dryer will reduce the time and energy required to dry your clothes. We tested dryer balls and found the only thing they dried up faster were the liquid assets in your wallet.
If you're always doing laundry, you can cut down on drying costs by air drying outside or switching to a heat pump dryer.
All dryers we've tested in the last few years have overheat detection, which means they turn off when the temperature gets too hot.
But to make sure you're extra safe, follow these few steps that most dryers will detail in their manuals:
- Follow the instructions in your manual.
- Plug your dryer directly into the power socket, not into a double adaptor, extension cord or power board.
- If wall mounting, ensure your drier is securely fastened to the wall following the manufacturer's instructions. Consider professional installation if DIY isn't your thing.
- Kids love to explore and can easily climb inside your dryer – if you have small children, avoid models which start automatically when the door is closed (see the criteria 'unit starts when door shuts' in the comparison table in our review).
- Allow good ventilation around the dryer.
- Don't load clothes that have had flammable materials spilled on them such as oils. Wash these in hot water with extra laundry detergent before drying.
- Only load clothes, towels and linen.
- Do not put items of clothing with rubber or foam attached to them.
- Don't store flammable items near the dryer.
- Clean your lint filter after every load (it saves time, energy and reduces potential damage to your clothes).
- Follow the clothing recommendations regarding tumble drying.
- Avoid using fabric softeners.
- Don't leave your dryer on while you aren't at home.
Your clothes dryer is a pretty hardy appliance. But if you don't look after it, you could increase your risk of fire, as well as machine failure.
Here's how to look after your clothes dryer so it gives you many years of safe use.
- Clean the lint filter – we can't stress this enough. Not only does a blocked lint filter reduce your dryer's efficiency, it's the major cause of dryer fires.
- Empty the water tank (condenser and heat pump models), or plumb it into a drain.
- Leave the door ajar when not in use (if possible) to help extend the life of the seal.
Clean external surfaces with a soft damp cloth.
Vacuum the lint out of air intakes, vents and crevices.

Yes, clothes shrink, and it's no stretch of the imagination (ha) to think that it's your dryer doing it. Specifically, the combination of heat and tumbling on wet fabrics.
How to stop clothes from shrinking in the dryer
The easiest way to avoid shrinkage is to line dry – good for the environment and it's free. But we get that's not always possible.
Known suspects such as woollen jumpers shouldn't go anywhere near your dryer – air dry instead, laid flat so they'll retain their shape.
For everything else, read (and follow) the care instructions on the label. It's pretty simple – if the label says do not tumble dry then don't tumble dry it. Likewise with anything that says cold wash only.
For a simple vented dryer you should use the warm setting, not hot, and don't over-dry your clothes.
For more complex dryers with several program options, choose the appropriate program for the fabric you're drying. You should also separate clothing into types and dry like with like – lighter T-shirts dry faster than heavier towels, so you risk over-drying them.
If you're a repeat offender, consider shrink-proof clothing – garments which have been 'pre-shrunk' during production so tension in the fibres has already been released.
