As Australia enters winter 2026, many households are bracing for higher energy bills. The reality is, some appliances are significantly more expensive to run than others, especially during colder months. Leading the charge are heating systems, hot water units, and clothes dryers, which collectively account for the lion’s share of winter energy consumption. Understanding their true running costs and implementing smart strategies can save Australian households hundreds, if not thousands, of dollars.
Australia’s energy landscape for 2026 sees varied electricity price movements. The Australian Energy Regulator (AER) announced its final Default Market Offer (DMO) for 2026-27, effective from 1 July 2026. Most residential customers on standing offers in New South Wales and South East Queensland will see price reductions between 3.4% and 7.7%. For example, NSW flat rate residential customers can expect a fall of $66 to $137, while South East Queensland customers will see a 7.2% ($155) decrease. However, South Australian residential flat rate customers will experience a modest 1.4% ($33) increase.
Victoria’s Essential Services Commission (ESC) has also confirmed a reduction in the Victorian Default Offer (VDO) by an average of 5% for residential customers, translating to average savings of $84 per year. In regional Queensland, regulated prices are set to fall by around 6.9% for typical Tariff 11 households, saving approximately $151 annually. This mixed bag of price changes means active engagement with your energy plan is crucial. For the purpose of cost calculations in this guide, we will use a national average residential electricity price of 33 cents per kilowatt-hour (c/kWh), though this varies significantly by state and network.
The Top Energy Guzzlers This Winter
When the mercury drops, certain appliances work harder, consuming more electricity or gas. Here’s a breakdown of the biggest culprits and their typical running costs, based on an average electricity price of 33c/kWh unless otherwise specified.
1. Heating Systems: The Biggest Bill Shock
Heating is unequivocally the most expensive appliance category in winter, often accounting for 20% to 50% of a household’s energy use. The type of heater you use dramatically impacts costs.
| Heater Type | Typical Power (kW) | Cost per Hour (approx.) | Winter Cost (90 days, 4.4 hrs/day) | Notes |
|---|---|---|---|---|
| Reverse Cycle Air Con | 1.0 - 2.5 (heating) | $0.15 - $0.40 | $60 - $160 | Most efficient electric heating, 300-600% more efficient than resistive. |
| Electric Fan Heater | 1.0 - 2.4 | $0.33 - $0.79 | $130 - $315 | Quick, targeted heat, but very inefficient for sustained use. |
| Oil Column Heater | 1.0 - 2.4 | $0.33 - $0.79 | $130 - $315 | Slower to heat, retains warmth, but less efficient than reverse cycle. |
| Electric Panel/Convection | 1.5 - 2.4 | $0.50 - $0.79 | $198 - $315 | Good for background heating, but high running costs. |
| Gas Heater (Space/Ducted) | 20-30 MJ/hr | $0.60 - $1.50 | $238 - $594 | Can be cheaper than resistive electric, but gas prices are rising in some states. |
Heating and cooling accounts for around 40% of the average energy use in Aussie homes, according to the Department of Climate Change, Energy, the Environment and Water.
Key Insight: Reverse cycle air conditioners (heat pumps) are by far the most energy-efficient heating solution, delivering 3 to 5 units of heat for every 1 unit of electricity consumed. While their upfront cost is higher ($2,000 - $6,000 for split systems like a Daikin Lite Series 2.5kW or Mitsubishi Electric MSZ-AP25VG; $8,000 - $15,000 for ducted), their low running costs make them the cheapest long-term option.

2. Hot Water Systems: The Silent Power Drainer
Water heating typically accounts for 15% to 30% of total household energy use. Traditional electric storage hot water systems are particularly inefficient, constantly reheating water even when not in use.
| Hot Water System Type | Annual Running Cost (Family of 4) | Notes |
|---|---|---|
| Electric Storage | $600 - $900 | Highest running costs, uses 2-4 kWh per day for simple usage. |
| Gas Storage | $400 - $600 | More efficient than electric storage, but gas prices are increasing in NSW and switching from gas to electric is encouraged in Victoria. |
| Continuous Flow Gas | $350 - $550 | Efficient, but still reliant on gas. |
| Heat Pump Hot Water | $150 - $300 (after rebates) | Uses up to 75% less electricity than traditional electric storage. Average installed cost $4,527, but drops significantly with federal STCs and state rebates (e.g., $2,667 in Victoria). |
| Solar Hot Water (with booster) | $100 - $200 | Lowest running costs, but higher upfront investment. |
Key Insight: Upgrading to a heat pump hot water system, such as a Rheem AmbiHeat HDc-270 or Sanden Eco Plus, can cut running costs by up to $740 per year compared to an old electric storage unit. With federal Small-scale Technology Certificates (STCs) and state rebates in Victoria (up to $1,000) and NSW (up to $1,400 via the Energy Savings Scheme), the upfront cost can be significantly reduced, making them a financially viable alternative.

3. Clothes Dryers: The Laundry Room Power Hog
Vented clothes dryers are notorious energy consumers. They expel warm, moist air, constantly drawing in new, cold air to heat, making them highly inefficient. Heat pump dryers, on the other hand, recirculate air, significantly reducing energy use.
| Dryer Type | Energy Use (kWh/cycle) | Cost per Cycle (approx. 33c/kWh) | Notes | Heat Pump (e.g., Bosch WTH85200AU) | 0.2 - 0.4 | $0.07 - $0.13 | $28 - $52 | Up to 70% more efficient than vented, gentler on clothes, but longer cycle times. | Vented Dryer (e.g., Electrolux EDV605H3WB) | 2.0 - 4.0 | $0.66 - $1.32 | $264 - $528 | Cheapest to buy, but most expensive to run. Expels warm, moist air.
Key Insight: While a vented dryer might cost $400-$700 upfront, a heat pump dryer like the Bosch WTH85200AU (around $1,200 - $1,600) or LG DVH9-09B (around $1,500 - $1,900) will pay for itself in energy savings over its lifespan. Running a heat pump dryer can save you over $400 per winter compared to a vented model, assuming frequent use.
Other Significant Winter Energy Users
Beyond the big three, several other appliances contribute to higher winter bills:
- Electric Blankets & Heated Throws: While individually low power (60-150W), prolonged use, especially overnight, can add up. A 100W blanket used for 8 hours costs around $0.26 per night, or $23.40 over a 90-day winter.
- Dishwashers: Heating water is the main energy draw. Using an eco-mode and ensuring full loads can reduce consumption. A typical cycle uses 1.2-2.0 kWh, costing $0.40-$0.66 per wash.
- Ovens & Cooktops: More frequent use for hearty winter meals. Batch cooking and using lids on stovetops can reduce energy waste. An electric oven can draw 2-3 kWh per hour, costing $0.66-$0.99 per hour of use.
General Strategies to Cut Winter Energy Costs
Beyond targeting specific appliances, broader household habits and upgrades can significantly reduce your overall winter energy expenditure.
- Shop Around for Energy Retailers: Even with DMO/VDO changes, market offers can provide better value. Use government comparison websites like Energy Made Easy (federal) or Victorian Energy Compare to find the best deals for your specific usage patterns. Don’t assume loyalty pays.
- Utilise Rebates & Incentives: Australia offers a range of federal and state-based incentives for energy-efficient upgrades. This includes federal STCs for solar panels and heat pump hot water, and state schemes like the Victorian Energy Upgrades (VEU) program or the NSW Energy Savings Scheme (ESS) for insulation, efficient lighting, and heating/cooling. These can significantly offset the upfront cost of upgrades. For more information on available support, consult: Navigating Australia’s Energy Bill Relief and Support in 2026: A Comprehensive Guide.
- Improve Home Insulation & Sealing: A well-insulated home retains heat more effectively, reducing the workload on your heating system. Seal gaps around windows and doors, use draft stoppers, and consider professional insulation upgrades for walls, ceilings, and floors. This is often the most cost-effective long-term strategy.
- Smart Home Energy Management: Implement smart plugs and timers for appliances like electric blankets or towel rails to ensure they only operate when needed. Smart thermostats can optimise heating schedules based on occupancy and external temperatures, preventing unnecessary energy use.
- Understand Your Bill: Regularly review your energy bill to track consumption and identify peak usage times. Many retailers offer apps or online portals that provide detailed insights into your energy habits.
Bottom Line
To significantly reduce your winter 2026 energy bills, focus on the big three: heating, hot water, and clothes drying. Prioritise upgrading to reverse cycle air conditioning for heating, a heat pump hot water system, and a heat pump clothes dryer. Leverage available federal and state rebates to make these investments more affordable. Combine these appliance upgrades with fundamental home improvements like insulation and draft sealing, and actively compare energy plans. By taking these steps, Australian households can realistically expect to slash hundreds, if not over $800, from their winter energy costs this year.
