Quick Answer
A heat pump dryer costs $50–$100 per year to run in Melbourne (at ~$0.32/kWh). A standard vented or condenser dryer costs $150–$350 per year depending on how many loads you do per week. The heat pump dryer uses 50–70% less electricity per load — at 6–7 loads per week, it can save $150–$250 per year compared to a conventional model.
How Much Does a Dryer Cost to Run?
For Melbourne households with limited outdoor drying space — terrace houses in Dandenong, apartments in Frankston, homes with small backyards in Berwick — a tumble dryer is a practical necessity. But running costs vary enormously between dryer types. Choosing the right one can cut your laundry electricity cost by more than half.
We use $0.32/kWh throughout these calculations (typical Victorian residential rate in 2026).
Running Cost Per Load by Dryer Type
| Dryer Type | kWh Per Load | Cost Per Load | 6 Loads/Week (Annual) |
|---|---|---|---|
| Heat pump dryer | 0.5–1.2 kWh | $0.16–$0.38 | $50–$120/year |
| Condenser dryer | 2.5–4.5 kWh | $0.80–$1.44 | $250–$450/year |
| Vented (exhaust) dryer | 3.0–5.5 kWh | $0.96–$1.76 | $300–$550/year |
| Gas dryer | ~0.5 kWh electricity + gas | $0.30–$0.60 total | $95–$190/year |
Annual Running Cost by Load Frequency
| Loads Per Week | Heat Pump Dryer | Condenser Dryer | Vented Dryer |
|---|---|---|---|
| 3 loads/week | $25–$60/year | $125–$225/year | $150–$275/year |
| 6 loads/week | $50–$120/year | $250–$450/year | $300–$550/year |
| 10 loads/week | $83–$200/year | $416–$750/year | $500–$916/year |
Heat Pump vs Condenser vs Vented: Which Is Right for You?
Heat Pump Dryers
Heat pump dryers work like a reverse air conditioner — they extract moisture from clothing using a refrigerant cycle rather than a direct heating element. They operate at lower temperatures (45–55°C vs 70–80°C for conventional dryers), which is gentler on fabrics and uses far less electricity. Upfront cost is higher: $900–$2,000 for a quality heat pump dryer vs $400–$800 for a standard condenser model. At 6 loads per week, they typically pay back the price difference in 2–4 years through electricity savings.
Condenser Dryers
Condenser dryers heat air, pass it through the drum, then cool the moisture out of the air and collect it in a removable tank (which you empty every 1–2 loads). No external venting required — they can be installed anywhere. Running cost is 3–4 times higher than a heat pump dryer but they cost $400–$900 to buy and are widely available.
Vented (Exhaust) Dryers
Vented dryers are the cheapest to buy ($300–$700) but the most expensive to run. They require a duct through an external wall or window to exhaust hot moist air. They are the most common older dryer type found in SE Melbourne homes built before 2010. If you have one, it is worth calculating whether the electricity saving from upgrading justifies the switch.
How to Reduce Dryer Running Costs
- Always spin clothes at high speed in the washing machine first — removing more water mechanically (which uses very little electricity) reduces drying time significantly. Each minute less in the dryer saves money.
- Clean the lint filter after every load — a clogged filter restricts airflow, making the dryer run longer. On heat pump models, also clean the heat exchanger filter monthly.
- Run full loads, not half loads — a half-empty dryer uses almost as much electricity as a full one.
- Use the moisture sensor setting (if available) — dryers with automatic sensors stop when clothes are dry, avoiding over-drying which wastes electricity and damages fabric.
- Pre-dry heavy items like towels on a rack for 30 minutes first — removing surface moisture before the dryer cycle cuts time significantly.
- Use off-peak tariffs if your plan offers them — run the dryer overnight at off-peak rates (typically 11pm–7am) if you’re on a time-of-use tariff.
- Don’t over-dry — clothes still slightly damp when removed can be line-aired for the last 10–15 minutes, cutting dryer time and saving electricity.
- In summer, line-dry where possible — even 2–3 fewer dryer loads per week adds up to $30–$80 per year in savings.

Frequently Asked Questions
How many kWh does a dryer use per load?
A heat pump dryer uses 0.5–1.2 kWh per load. A condenser or vented dryer uses 2.5–5.5 kWh per load depending on load size and dampness. At $0.32/kWh, a heat pump load costs 16–38 cents; a conventional dryer load costs 80 cents to $1.76. Over a year at 6 loads per week, that’s a difference of $150–$350.
Is a heat pump dryer worth the extra cost?
For most Melbourne households doing 5+ loads per week, yes. A heat pump dryer saves $150–$350 per year in electricity compared to a conventional model. With a price premium of $400–$700 over a standard condenser dryer, the payback period is typically 2–4 years. After that, you save money every year for the life of the appliance (usually 10–15 years).
Can I use a dryer on solar power to reduce running costs?
Yes — running the dryer during the middle of the day when your solar system is generating (roughly 10am–3pm in Melbourne) effectively makes it free to operate if your system is large enough. This works especially well with heat pump dryers, which draw a lower peak current (around 750W–1kW vs 2.5–4kW for a conventional dryer).
Why does my dryer take so long to dry clothes?
The most common causes are: a clogged lint filter (clean after every load), a blocked external vent duct (check for lint buildup or bird nests in the wall duct), clothes that were not adequately spun in the washing machine (run a fast spin cycle first), or overloading the drum (a full overloaded drum dries unevenly and takes much longer than two normal loads).
How much does it cost to run a dryer in Australia compared to air drying?
Air drying is free. A heat pump dryer at 6 loads per week costs $50–$120 per year; a conventional dryer costs $300–$550 per year. In Melbourne’s climate, air drying works well for 8–9 months of the year. Using the dryer only in winter and for towels/sheets can cut annual dryer costs by 50–60%.
