Most Energy-Efficient Clothes Dryers

Energy-efficient appliances are good for both your wallet, and the environment. Canstar Blue takes a look at the most energy-efficient clothes dryers you can buy in New Zealand.

The cost of running household appliances quickly adds up. If you’re looking to save money, or reduce your carbon footprint, taking into account the energy usage of your appliances is crucial, as the energy efficiency of your appliances can play a big role in the ongoing electricity costs of your home. For example, clothes dryers with a low energy rating can cost around 5x more per load than more energy-efficient clothes dryers. 

So if you’re in the hunt for a new dryer, it pays to consider just how energy efficient it is.

What do you mean by energy efficient?

Appliances in New Zealand are given an energy star rating out of six. The more stars an appliance is awarded, the more energy efficient it is considered. Meaning, it sucks up less power when in use. Some models that are considered to be extremely energy efficient qualify for extra stars, up to a total of ten. This is considered a super-efficiency rating, and many energy-efficient clothes dryers in the market now qualify for one of these ratings.

A dryer with high energy efficiency will not only save you money, but will help reduce the carbon footprint of your machine.

Things to consider before you buy

There are three main types of clothes dryers available: ventilated, condenser and heat pump.

Ventilated dryers

These dryers take air from a room, heat it to dry clothes and then expel it once it has become too moist. Because these dryers release hot, moist air, they’re not appropriate for cramped, internal spaces, such as closet laundries, which are common in apartments. They require appropriate ventilation or ducts. Usually the cheapest to buy, they’re not very energy-efficient.

Condenser dryer

Condenser dryers recycle hot air by extracting the water vapour from the hot air, before sending it back through the clothes in the dryer. The extracted moisture is drained away, so no moist air is expelled from the dryer. Because of this, they are more appropriate for tight spaces. However, these dryers are typically too heavy to be wall-mounted. Although, they can be stacked on top of a front loader. Again, these dryers are not energy-efficient, typically ranging from just 2-3.5 stars.

Heat pump dryer

Heat pump dryers work in a closed-loop. Air is heated and pushed through the clothes before it is then cooled. This cooling drains the water off. The now cool air is then reheated again to go back through the clothes. A heat pump dryer is typically the most expensive option, but are by far the most energy-efficient clothes dryers. They can be wall-mounted and used in tight spaces.

The most energy-efficient clothes dryers

To help you in your hunt for a new dryer, we’ve listed some of the most energy-efficient dryers, currently available, in order of lowest annual running costs. As mentioned above, heat pump dryers are considerably more energy-efficient, so all the dryers mentioned below (except where stated) are heat pump dryers.

Annual running costs are estimated on the assumption of one load daily, and have been sourced via Gen Less’ Rightware tool. Prices best prices at time of writing.

The most energy-efficient clothes dryers, ventilated and condenser (super budget)

If you are looking for a cheaper clothes dryer, that will still save on your power bill, ventilated or condenser dryers are an option. While none on the market offer the same energy efficiency as heat pump dryers (none earn a super energy-efficiency rating, for example) the initial costs can be much more affordable.

However, while a ventilated dryer will almost always be cheaper, a low-end heat pump dryer, such as the ones mentioned above, can often be comparable with the average condenser model, while still being much more energy-efficient.

Vogue 361173 (ventilated) ($649)

  • Annual running costs: $72
  • Energy star rating: 2.5
  • Load capacity: 7kg

Midea MDS70-C05/B08-AU (condenser)  ($649)

  • Annual running costs: $79
  • Energy star rating: 2
  • Load capacity: 7kg

The most energy-efficient clothes dryers: large load capacity

Samsung energy-efficient clothes dryer
Samsung DV10T9720SV

While clothes dryers don’t come in the same size as your largest washing machines, you can still find dryers large enough for most household jobs.

The largest load capacity on the market you tend to find is 10kgs, which is plenty to do a family load of washing. This is big enough to hold bedding such as a duvet as well, but particularly large loads may still require an industrial-sized dryer, found in a laundromat.

Samsung DV10T9720SV ($2899)

  • Annual running costs: $32
  • Energy star rating: 9-star super efficiency rating
  • Load capacity: 10kg

How can I lower the energy use of my clothes dryer?

There are plenty of little tips and tricks to help limit the amount of power used by your clothes dryer. A few to try are:

  • Avoid having it on standby, turn it off at the wall
  • Avoid drying loads of laundry that are too small or too large. Too small and it’s wasteful, too large and clothes won’t ventilate and dry efficiently. The warm air needs to move through the clothes
  • Use dryer balls to speed up dry time. Dryer balls absorb moisture while also tumbling through the dryer, separating clothes and improving ventilation through the washing
  • Switch loads while the dryer is still warm
  • Dry heavyweight items separately. The dryer will continue to run until the heaviest items are dry, meaning any small items included will dry longer than necessary
  • Use features, such as a cool-down cycle, which finishes drying with the remaining heated air left in the dryer

Finding the best power provider

While energy-efficient appliances are a great way to save you money, you also need to be getting a good deal on your power. While less than half of Kiwis believe they are getting a good deal on their power, only 12% of us have actually changed our electricity provider in the last 12-months.

Ultimately, finding affordable power involves shopping around. And the fact that you’re reading this means that you’re already on the right track to finding a great deal on power. But when comparing power companies, it’s important to consider the broader picture – don’t become too focused on finding a deal with a big prompt payment discount or special perk. Be sure to balance all the rates, discounts, fees and contract periods when making a decision, as well as more personal factors, such as customer service and support.
