As Australian winters settle in, many households turn to portable electric heaters for targeted warmth. While convenient, their running costs can quickly add up, especially with varying electricity prices across states. This guide breaks down the running costs of popular portable electric heater types in Australia for 2026, helping you make an informed decision to stay warm without excessive energy bills.
On average, a 2400W portable electric heater used for 3 hours a day could cost between $3.24 and $4.86 daily in 2026, depending on your electricity tariff and state. This translates to a monthly cost of approximately $97 to $146.
How to Calculate Your Portable Heater’s Running Cost
Calculating the running cost of any electric appliance is straightforward. You need two key pieces of information: the appliance’s wattage (power consumption) and your electricity tariff (cost per kilowatt-hour).
Here’s the formula:
(Heater Wattage (W) / 1000) * Hours Used * Electricity Cost (AUD/kWh) = Running Cost (AUD)
For example, a 2400W heater used for 3 hours with an electricity cost of $0.45/kWh:
(2400W / 1000) * 3 hours * $0.45/kWh = $3.24 per day
Over a month (30 days), this would be $3.24 * 30 = $97.20.
Australian Electricity Prices in 2026: What You Need to Know
Electricity prices in Australia for 2026-27 are seeing varied changes across the National Electricity Market (NEM). The Australian Energy Regulator (AER) announced its Default Market Offer (DMO) for New South Wales, South East Queensland, and South Australia, applicable from 1 July 2026. Most households on flat rate standing offers in NSW will see prices fall by 3.4% to 5.0%, and in South East Queensland by 7.2%. South Australia, however, will experience a modest increase of 1.4%.
Victoria, operating under its own Essential Services Commission (ESC), has set the Victorian Default Offer (VDO) for 2026-27. This sees average annual bills for domestic customers fall by approximately 5% compared to the previous year, driven by lower environmental, wholesale, and network costs.
The DMO and VDO serve as a regulated safety net for customers on standing offers and act as a reference price for comparing market offers. While these default offers provide a benchmark, market offers from retailers can vary significantly.
For illustrative purposes in this guide, we’ll use a representative average electricity price of $0.45 per kilowatt-hour (kWh). However, your actual cost will depend on your specific retailer, tariff (e.g., flat rate, time-of-use), and distribution zone. It is crucial to compare market offers to find the best deal.

End of Universal Federal Energy Bill Relief
It is important for consumers to note that the universal federal Energy Bill Relief Fund, which provided $300 to households in 2024-25 and a further $150 in the first two quarters of 2025-26, ended on 31 December 2025. There are no new universal federal energy credits in place from January 2026. However, some state-specific concession programs continue, and there is mention of a “Phase 2 of the $275 Energy Credit” confirmed for 2026, rolling out progressively and targeted at eligible households and small businesses. For details on available state support and concessions, see our guides on Australian Energy Bill Relief & Utility Concessions 2026: Your Comprehensive Guide and Australian Energy Rebates in 2026: Your State-by-State Guide After Federal Relief Ends.

Panel Heaters
How they work: Panel heaters (convection heaters) warm the air around them, circulating it throughout the room. They are known for providing gentle, consistent heat and are often silent. Many models, like the Noirot Spot Plus, feature precise thermostats that maintain temperature within 0.1°C, reducing energy waste.
Running Cost Profile: Moderate. They are efficient for heating a whole room over time, particularly when paired with a good thermostat and timer. However, their slow heating means they run for longer.
Oil Column Heaters
How they work: These heaters contain oil that is heated by an electric element. The warm oil circulates through fins, radiating heat into the room. They retain heat well, continuing to emit warmth even after being switched off.
Running Cost Profile: Moderate to high. While they provide sustained warmth and are silent, they take longer to heat a room initially and can consume significant power if used continuously. Models like the Arlec 1000W 5 Fin are suitable for smaller rooms, while 2400W models are for larger spaces.
Radiant Heaters
How they work: Radiant heaters use quartz or halogen tubes to generate infrared heat, directly warming people and objects in their path, similar to sunlight. They provide instant, directional warmth.
Running Cost Profile: Can be cost-effective for spot heating or in draughty areas where heating the entire air volume is impractical. For example, a Goldair 1200W radiant heater is good for personal warmth. However, they are less effective for warming an entire room uniformly and can be inefficient if relied upon for whole-room heating.
Fan Heaters
How they work: Fan heaters use a fan to blow air over a heating element, quickly distributing warm air into a space. Ceramic fan heaters, like the Kogan Portable Ceramic Heater, use ceramic plates for efficient heat transfer.
Running Cost Profile: Generally high for continuous use. They are excellent for rapid, short-term heating of small areas but can be energy-intensive if run for extended periods, especially higher wattage models. Their quick heat-up time can be beneficial for specific situations, but their efficiency drops off for sustained heating compared to other types with good thermostats.
Strategies to Reduce Your Heating Costs
- Match Heater to Room Size: Using a small heater in a large room or an oversized heater in a small room is inefficient. Match the wattage to the area you need to heat. For instance, a 1000W heater for a small room (up to 10m²), 1500W for medium (up to 15m²), and 2400W for larger spaces (20-25m²).
- Utilise Thermostats and Timers: Most modern portable heaters come with adjustable thermostats and timers. Set the thermostat to a comfortable temperature (e.g., 18-20°C) rather than maximum heat. Use timers to only run the heater when you are in the room or just before you arrive. This prevents unnecessary energy consumption.
- Insulation and Draught Proofing: Addressing heat loss through poor insulation and draughts is one of the most effective ways to reduce heating needs. Sealing gaps around windows and doors, and improving ceiling insulation, can dramatically cut down the amount of time your heater needs to run.

- Zone Heating: Instead of trying to heat your entire home, focus on heating only the rooms you are actively using. Portable heaters excel at this by providing warmth exactly where and when it’s needed.
- Compare Electricity Plans: With DMO and VDO prices shifting in 2026-27, it’s a good time to review your electricity plan. Market offers often provide better rates than standing offers. Use energy comparison websites to ensure you are on the most competitive tariff for your usage patterns.
Bottom Line
Choosing the right portable electric heater in Australia for 2026 involves more than just the upfront purchase price. Understanding the running costs, driven by wattage and your electricity tariff, is crucial for managing your energy budget. While all electric heaters convert electricity to heat at near 100% efficiency, their effectiveness and perceived running costs vary based on how they distribute that heat and how wisely they are used.
For sustained, whole-room heating, panel heaters or oil column heaters with thermostats and timers offer a balanced approach to comfort and cost. For instant, targeted warmth, radiant heaters are highly effective in personal spaces. Fan heaters are best for quick bursts of heat in small areas. Regardless of type, active management through thermostats, timers, and improving home insulation will be your most powerful tools in controlling winter energy bills in 2026 and beyond.
