Winter laundry in much of Australia forces a choice between endless indoor clothes racks or a spike in power bills from a traditional vented dryer. It’s a small, recurring frustration, but it also makes clothes dryers one of the easiest appliances to fix. Heat pump dryers now sit alongside heat pump hot water systems and induction cooktops as a core part of household electrification, and unlike some of those bigger-ticket upgrades, a heat pump dryer is a straightforward, high-yield swap that doesn’t require rewiring or a major installation.
How it works, without the high energy bill
A vented dryer heats air with a resistive element, blows it through wet laundry, and expels the resulting warm, moist air outside through a duct or straight into the room. That heating element is the single biggest reason vented dryers use so much power: every load starts from scratch, heating fresh air that gets used once and thrown away.
A heat pump dryer works differently. It uses a closed-loop system, similar in principle to a refrigerator or reverse-cycle air conditioner, to extract moisture from the air inside the drum and recycle the warmth rather than expelling it. Because the air is recycled instead of reheated from scratch, the appliance draws a fraction of the power a resistive vented dryer needs.
That efficiency shows up clearly on the energy rating label. Basic vented dryers in Australia are commonly rated in the 1 to 3-star range under the local clothes dryer star rating scheme, while heat pump models regularly reach 8 or 9 stars, and Electrolux’s UltimateCare 900 range is currently the only 10-star rated clothes dryer sold in Australia. The other practical benefit is just as important for a lot of households: because a heat pump dryer doesn’t expel warm, damp air, it doesn’t need external venting or an open window, and it doesn’t add moisture to the room, which is a common contributor to winter mould and damaged laundry walls.
The dollars and cents: an Australian cost breakdown
Running cost is where a heat pump dryer earns its keep, but the actual numbers depend heavily on which models you’re comparing and how many loads you run each week.
Based on current Australian retail and energy pricing, a vented dryer typically uses somewhere between 2.4 and 5 kWh per load, depending on load size and cycle length, while a comparable heat pump dryer uses roughly 1 to 2.5 kWh. At a typical Australian electricity rate of around 30 cents per kWh, that translates to roughly 70 cents to $1.50 per load for a vented dryer, against 30 to 75 cents for a heat pump model, and effectively nothing when a cycle is run entirely on excess solar generation.
Over a year of moderate use, at three to four loads a week, that gap adds up. Industry cost comparisons published in 2026 put typical annual running costs at around $220 to $300 for a vented dryer versus $55 to $100 for a heat pump dryer at the same usage, a difference of roughly $150 to $230 a year.
On the purchase side, an entry-level vented dryer typically costs from around $400 to $600, while heat pump models start from roughly $900 to $1,500 for mainstream 8-star options, with premium 9 and 10-star models reaching $2,000 or more. That price premium, weighed against the running cost savings above, generally pays for itself in around three to five years for a household doing several loads a week, a little faster for larger households and slower for occasional users. Households timing cycles to run on self-generated solar, or already paying above-average electricity rates, tend to see payback at the faster end of that range.
Maximising your electrified home integration
Matching drying cycles to solar generation. Most heat pump dryers draw somewhere between 600 and 900 watts during a cycle, comfortably within what a typical rooftop solar system generates around the middle of the day. Using a dryer’s built-in delay timer, or a smart plug with a schedule, to start a cycle during peak solar hours turns electricity that would otherwise be exported at a low feed-in tariff into essentially free laundry drying.
Choosing a drainage setup. Heat pump dryers condense moisture out of the air as they run, and that water needs to go somewhere. Most models offer a removable internal water tank that needs manual emptying every load or two, which suits renters or anyone who can’t plumb a drain line. Alternatively, most heat pump dryers can have their drain hose connected directly to a laundry sink outlet or standpipe, which removes the need to empty a tank at all. Check that your chosen model supports a direct-plumb option before assuming it does, since not every model includes the fitting as standard.
Gentler fabric care. Because heat pump dryers operate at lower temperatures than resistive vented dryers, they tend to be gentler on fabric, with less heat-related shrinkage and less wear over the life of a garment. Cycle times are typically longer as a trade-off, so if speed matters more than fabric care for your household, factor that into which model you choose.
What to look for before buying
A few specs are worth checking against the label rather than the marketing copy:
- Star rating and capacity together. A star rating reflects efficiency relative to a dryer’s own capacity, so a smaller 7kg model and a larger 10kg model with the same star rating don’t necessarily use the same amount of energy per load. Check the kWh-per-year figure on the label, not just the star count.
- Self-cleaning condensers. Heat pump dryers rely on a heat exchanger that needs to stay clean to keep running efficiently. Models with self-cleaning or easy-access condensers cut down on manual maintenance considerably.
- Lint filter design and location. A poorly placed or hard-to-clean lint filter is a common source of owner complaints and can gradually reduce drying performance if it’s neglected.
- Cycle speed options. Heat pump dryers are generally slower than vented models. A quick-dry or express cycle option is worth having if you regularly need a fast turnaround, even though it typically uses more energy per load than the standard cycle.
State rebates and where they actually apply
Support for heat pump dryers varies significantly by state, and it’s worth checking the details rather than assuming a scheme covers what you expect.
In Victoria, the Victorian Energy Upgrades (VEU) program includes clothes dryers as a specific eligible activity (Activity 25), but the discount is modest: current guidance from Sustainability Victoria lists a discount of up to $70 on an eligible heat pump dryer, applied through an accredited provider at the point of sale. It’s a genuine saving, but it’s smaller than VEU discounts for bigger-ticket items like heat pump hot water systems, so it shouldn’t be the deciding factor in a purchase on its own.
In South Australia, the Retailer Energy Productivity Scheme (REPS) offers a considerably larger rebate for eligible fridges, freezers and heat pump dryers, up to roughly $565 to $606 depending on the retailer and model, provided the dryer meets a minimum 5.5-star rating and 3kg capacity. This is available through REPS-obliged retailers and activity providers rather than automatically at every retailer, so check that your chosen supplier participates before assuming eligibility.
Other states don’t currently offer an equivalent dryer-specific rebate at the time of writing, so if you’re outside Victoria or South Australia, the running-cost savings and any federal or retailer-specific promotions are likely to be the main financial factors in the decision.
FAQs
How much electricity does a heat pump dryer use compared to a vented dryer? A heat pump dryer typically uses around 1 to 2.5 kWh per load, compared to roughly 2.4 to 5 kWh for a vented dryer, a reduction of up to 70 to 75 per cent depending on the specific models being compared.
How long does it take a heat pump dryer to pay for itself? For a household doing three to four loads a week, the price premium over a vented dryer typically pays back in around three to five years through lower running costs, faster for larger households or those on higher electricity rates, and faster still if cycles are run on self-generated solar.
Do heat pump dryers need external venting? No. Heat pump dryers recycle air in a closed loop rather than expelling warm, moist air outside, so they don’t require external venting, a wall vent, or an open window, and don’t add humidity to the room they’re used in.
Are there rebates for heat pump dryers in Australia? Victoria’s VEU program offers a modest rebate of up to $70 on eligible heat pump dryers. South Australia’s REPS offers a larger rebate of up to roughly $565 to $606 for eligible models. No equivalent scheme currently exists in other states.
Can I run a heat pump dryer on solar power? Yes. Most heat pump dryers draw 600 to 900 watts, which fits comfortably within a typical rooftop solar system’s midday output. Using a delay timer to run cycles during peak solar generation can make the electricity cost close to zero.
