As Australia enters winter 2026, households are keenly focused on managing heating costs amidst fluctuating electricity prices. The most energy-efficient electric heaters for Australian homes in 2026 combine effective warmth with smart features to minimise running expenses. For targeted heating, oil column heaters like the De’Longhi Dragon 4 (2400W, around $339) and panel heaters such as the Rinnai PEPH Series (2200W, prices vary) offer strong performance. For rapid spot heating, a 2000W Ceramic Tower Heater (from around $75) remains a budget-friendly choice.
Electricity prices are seeing varied shifts across states from 1 July 2026. While some regions, like New South Wales and South East Queensland, anticipate reductions in Default Market Offer (DMO) standing offer prices, South Australia residential flat rates will experience a slight increase. Understanding these changes and choosing the right heater can significantly impact your winter energy bills.
Understanding Australia’s 2026 Electricity Landscape
Australia’s energy market is dynamic. The Australian Energy Regulator (AER) and the Essential Services Commission (ESC) in Victoria have recently released their Default Market Offer (DMO) and Victorian Default Offer (VDO) determinations for the 2026-27 financial year, effective from 1 July 2026. These set the maximum prices retailers can charge customers on standing offer contracts and serve as a benchmark for market offers.
“This is a positive outcome with prices coming down for the majority of households and all small businesses across the three regions where the DMO safety net applies.” – AER Chair Clare Savage on the 2026-27 DMO.
Key Price Changes from 1 July 2026:
| State/Region | Residential Flat Rate Standing Offer Change (Annual) | Residential Time-of-Use Standing Offer Change (Annual) |
|---|---|---|
| New South Wales | -3.4% to -5.0% (saving $66 to $137) | -3.7% to -7.7% (saving $72 to $211) |
| South East QLD | -7.2% (saving $155) | -10.7% (saving $229) |
| South Australia | +1.4% (increase $33) | -1.1% (saving $25) |
| Victoria (VDO) | Average -5% (saving $84) | (Included in average) |
| Regional QLD (Ergon) | ~-9.7% (saving ~$212 for typical usage) | (Included in average) |
Average electricity usage rates for residential customers in 2026 typically range from 26.8 c/kWh in Victoria to 28.5 c/kWh in NSW and can be as high as 43.9 c/kWh in parts of South Australia. Daily supply charges average around $1.02 in Victoria and $1.20 in NSW. These rates directly impact the running costs of your electric heater.

Energy Bill Relief and Rebates in 2026
Australian governments are offering various forms of energy bill relief in 2026:
- National Energy Bill Relief: Many households in NSW and WA are receiving a $150 credit in the 2025-26 financial year, often in quarterly instalments. Check with your retailer or state service (e.g., Service NSW) if you are in an embedded network.
- NSW State Rebates: Eligible households can access the Low Income Household Rebate ($285), Family Energy Rebate, Medical Energy Rebate, and the Seniors Energy Rebate ($200 for Commonwealth Seniors Health Card holders).
- Victorian Concessions: Eligible low-income households can access the Energy Concession.
- South Australian Concessions: Up to $281.78 per year for eligible low-income households.
- Solar Sharer Offer: From 1 July 2026, smart meter households in DMO regions (NSW, SA, SE QLD) can opt into a new plan offering three hours of free electricity in the middle of the day, potentially saving up to 24 kWh daily by shifting usage. This can significantly reduce the cost of running appliances, including heaters, if timed correctly.

Top Energy-Efficient Electric Heaters in Australia 2026
When choosing an electric heater, consider the room size, how quickly you need heat, and how long you need it for. While reverse cycle air conditioners are generally the most energy-efficient for whole-home heating, portable electric heaters are ideal for specific rooms or supplementary warmth.
1. Oil Column Heaters: Consistent, Silent Warmth
Oil column heaters work by heating oil sealed inside fins, which then radiates heat into the room. They take longer to warm up but retain heat effectively, making them efficient for sustained warmth, especially overnight. They are also silent.
| Model | Power (W) | Approx. Price (AUD) | Key Features |
|---|---|---|---|
| De’Longhi Dragon 4 TRD42400MT | 2400 | $339 - $379 | Radiant heating, 24-hour timer, thermostat, thermal cut-off, 7-year warranty. |
| De’Longhi Dragon 5 Easytronic TRD51024T | 2400 | $385 | Easytronic controls for precise temperature, ideal for rooms up to 45m². |
| De’Longhi Radia S Digital TRRS1224EG | 2400 | $289 | 12 specially shaped fins for faster heat, digital controls. |
Running Cost Example (2400W heater, 3 hours/day, NSW average 28.5 c/kWh): 2.4 kW * 3 hours * 28.5 c/kWh = $2.05 per day (approx. $61.50 per month).
2. Panel Heaters: Slim Design, Quick Convection
Panel heaters (convection heaters) heat an internal element and warm the surrounding air, often resulting in quicker heat distribution than oil heaters. Many are slimline and can be wall-mounted or freestanding.
| Model | Power (W) | Approx. Price (AUD) | Key Features |
|---|---|---|---|
| Rinnai PEPH Series Panel Heater | 1000-2200 | $150 - $300+ | Digital thermostat, 24-hour timer, overheat protection, wall-mount/freestanding. |
| Nobo Panel Heater | 1500-2400 | $350 - $550+ | Minimalist design, precise thermostat, fan-free operation (good for allergies). |
| Dimplex 2.4kW Panel Heater | 2400 | $200 - $350+ | Wall-mountable, timer, even heat distribution. |
| Ausclimate EcoSmart Pro Panel Heater | 2000 | $426 | Slimline, quiet, good temperature retention. |
Running Cost Example (2000W heater, 3 hours/day, VIC average 26.8 c/kWh): 2.0 kW * 3 hours * 26.8 c/kWh = $1.61 per day (approx. $48.30 per month).
3. Ceramic Heaters: Rapid Spot Heating
Ceramic heaters use a ceramic heating element to deliver rapid, directed heat. They are excellent for quickly warming a small area, like a home office or bedroom. Look for oscillating functions to distribute heat more widely.
| Model | Power (W) | Approx. Price (AUD) | Key Features |
|---|---|---|---|
| Goldair 2400W Ceramic Tower Heater | 2400 | $75 - $117 | Oscillating, remote control, fast heat, tip-over and overheat protection. |
| Generic 2000W Ceramic Tower Heater | 2000 | $75 | Rapid, even heat, quiet operation, slim profile, safety features. |
Running Cost Example (2000W heater, 2 hours/day, SA average 36.5 c/kWh): 2.0 kW * 2 hours * 36.5 c/kWh = $1.46 per day (approx. $43.80 per month).
What to Look for in an Energy-Efficient Electric Heater
- Thermostat and Timer: Essential for managing running costs. A thermostat maintains a set temperature, cycling the heater on and off, while a timer allows you to program operation.
- Wattage (kW) vs. Room Size: A general rule of thumb is 80-100W per square metre. A 2000W heater is suitable for a 20-25m² room.
- Safety Features: Overheat protection and tip-over auto-shutoff are crucial, especially in homes with children or pets.
- Portability: Castor wheels or lightweight designs make it easy to move the heater between rooms, ensuring you only heat the space you’re in.
- Smart Features: Some advanced models offer app control, integration with smart home systems, or energy-saving modes (e.g., De’Longhi’s Eco Plus). These can provide greater control and optimise usage.
- Consider your Electricity Plan: If you’re on a time-of-use tariff, or are considering the new Solar Sharer Offer, timing your heater use during off-peak or free periods can significantly reduce costs. It’s always worth reviewing your plan: Best Electricity Plans in Australia 2026: A Comprehensive Guide for Households to Cut Costs.
