Fan, radiant, ceramic, panel and oil column heaters all use electric resistance heating, so models with a similar wattage generally cost a similar amount to run at full power. However, actual oil heater power consumption can vary as the thermostat cycles the heating element on and off after the room reaches the set temperature. The main differences between these heaters lie in how quickly they deliver heat, how evenly they warm a room and how effectively their thermostats control operation. Reverse-cycle air conditioners usually use less electricity to provide the same amount of warmth, making them a more economical option for regular room heating.
How to Choose the Most Efficient Room Heater for Your Home
Choosing the right heater requires careful consideration, as different options offer different levels of performance and efficiency. Finding the most suitable option can help households identify the least expensive heater to run while maintaining a comfortable indoor environment.
1. Compare the Right Efficiency Information
For reverse-cycle air conditioners, check the Zoned Energy Rating Label and compare the heating efficiency for your climate zone. Portable electric heaters are better compared by rated wattage, thermostat controls, room coverage and expected operating time, as they may not carry the same type of energy rating label.
2. Consider Room Size and Heating Area
The right heater size depends on the area that needs heating. Small heaters are usually suitable for bedrooms, offices, or small living spaces, while larger rooms may require a more powerful heating solution. Choosing a heater that suits the room size can provide more consistent warmth and reduce the risk of running an undersized unit continuously. Choosing a heater that suits the room size can provide more consistent warmth and reduce the risk of running an undersized unit continuously.
3. Compare Running Costs Before Buying
A heater with a lower purchase price may not always be the cheapest option in the long term. Households should consider power consumption and how many hours the heater will run each day. Comparing estimated running costs can help identify a heater that offers better value throughout the winter.
4. Match the Heater to Your Usage Needs
Different heating habits require different solutions. If you only need warmth for a short period, a quick-heating option may be more practical. For people who use heating for several hours every day, choosing a more efficient model can provide consistent comfort while keeping electricity consumption lower.
5. Consider Your Budget and Long-Term Value
Budget is an important factor when choosing a heater, but households should also consider long-term value rather than only the initial cost. Some heaters may require a higher upfront investment but can provide better efficiency and lower running costs over time.
How to Reduce Heating Costs and Heat Your Home More Efficiently
Heating your home affordably is not only about choosing the right heater, but also about using it efficiently and applying simple, low-cost strategies. Managing heating costs in winter can help Australian households stay warm while keeping energy bills under control.
1. Improve Home Insulation
Start with lower-cost measures such as sealing draughts around doors and windows and closing curtains after sunset. Larger insulation upgrades may deliver longer-term savings but require a higher upfront investment.
2. Use Timers and Thermostats
Timers can limit heating to occupied periods, while thermostats prevent a room from becoming warmer than necessary. Where comfortable, set heating between 18°C and 20°C. According to the Australian Government, each additional degree can add around 5–10% to heating costs.
3. Maintain Your Heating Equipment
Regular maintenance supports safe and effective operation. Clean or replace reverse-cycle air conditioner filters as recommended, and keep the vents and grilles of portable heaters free from dust and obstructions. Check power cords, plugs and safety features before winter, and stop using any heater that shows signs of damage or overheating.
4. Take Advantage of Off-Peak Electricity Rates
If your household is on a time-of-use electricity plan, charging a portable power station during lower-priced off-peak periods and using the stored energy during peak periods may reduce grid costs. However, potential savings depend on the tariff difference, charging and conversion losses, battery capacity and heater runtime. Check your electricity plan before relying on this strategy.

FAQs
How much does it cost to run a 2000 watt heater for 1 hour?
A 2,000 W heater uses up to 2 kWh of electricity per hour when operating continuously at full power. At an electricity rate of 30 cents per kWh, that would cost about 60 cents per hour. Actual costs may be lower when the thermostat cycles the heating element on and off.
Is it better to keep heating on low all day or just when needed?
In most homes, it is more economical to heat occupied rooms when needed and use a timer or programmable thermostat to avoid unnecessary operation. The best schedule still depends on the heating system, insulation and local climate, but leaving heating on all day is not automatically cheaper.
What is the most common mistake people make when heating their homes in winter?
One of the most common mistakes people make is choosing or using a heater without considering their actual One common mistake is setting the thermostat too high while allowing warm air to escape through gaps around doors and windows. Heating unused rooms and leaving a heater running when no one is home can also increase costs. Choosing the right heating area, sealing draughts and using timers can reduce unnecessary energy use.
