Gas vs. Electric Heating: Choosing the Right Option for Your Home
When the cooler months arrive, a reliable and efficient heating system becomes a necessity. In Australia, gas and electric heating are two of the most common choices. However, deciding which is best for your home involves carefully considering various factors, including cost, energy efficiency, environmental impact, safety, and the size of your home. This comprehensive comparison will help you make an informed decision.
Cost Comparison (Installation and Running Costs)
One of the primary considerations when selecting a heating system is the overall cost, which encompasses both the initial installation expenses and the ongoing running costs.
Installation Costs
Gas Heating: Installing a gas heating system typically involves higher upfront costs. This is because it requires a gas line connection, which may involve trenching and piping if one isn't already present. The cost can also vary depending on the type of gas heater, such as ducted gas heating or a gas space heater. Expect to pay more for professional installation due to the complexities of gas line connections and safety regulations.
Electric Heating: Electric heating systems generally have lower installation costs. Portable electric heaters require no installation, while wall-mounted or ducted electric systems are simpler and less expensive to install than their gas counterparts. The main cost factor is the electrical wiring and circuit capacity required, which might necessitate upgrades in older homes.
Running Costs
The ongoing running costs of a heating system are a significant factor in the long term.
Gas Heating: Gas prices can fluctuate, but natural gas is often cheaper than electricity per unit of energy (kilowatt-hour or kWh). However, this can vary depending on your location and gas supplier. Gas heating systems, especially ducted systems, can be efficient at heating large areas, potentially offsetting the cost difference.
Electric Heating: While electric heaters may be cheaper to purchase, electricity prices are generally higher than gas prices. This can lead to higher running costs, especially if you are heating a large area or using less efficient electric heaters. However, some modern electric heating options, like heat pumps, can be very energy-efficient and reduce running costs. Consider what Indoorliving offers in terms of energy-efficient solutions.
To accurately compare running costs, it's essential to check current gas and electricity prices in your area and estimate your heating needs based on your home size and usage patterns. Also, consider the energy efficiency rating of the specific models you are comparing.
Energy Efficiency and Performance
Energy efficiency is crucial for reducing both your energy bills and your environmental footprint. The performance of a heating system also affects your comfort levels.
Energy Efficiency Ratings
Gas Heating: Gas heaters have an energy efficiency rating that indicates how much of the gas they burn is converted into usable heat. Modern gas heaters can have high-efficiency ratings, but older models may be less efficient. Look for models with a high star rating to maximise efficiency.
Electric Heating: The energy efficiency of electric heaters varies widely. Traditional resistance heaters (like electric radiators) are 100% efficient in converting electricity to heat within the heater itself, but that electricity may have been generated inefficiently (e.g., by burning coal). Heat pumps, on the other hand, are far more efficient because they move heat rather than generating it. They can deliver several times more heat energy than the electrical energy they consume, making them a very efficient choice. Frequently asked questions often cover the differences in energy efficiency.
Heating Performance
Gas Heating: Gas heating systems, particularly ducted systems, are known for their ability to quickly and effectively heat large areas. They provide consistent and even heat distribution, creating a comfortable environment throughout the home. However, they can sometimes create a dry atmosphere.
Electric Heating: Electric heaters offer a range of performance characteristics. Portable electric heaters are suitable for heating small spaces, while ducted electric systems can heat larger areas. Heat pumps offer both heating and cooling capabilities, making them a versatile option for year-round comfort. Some electric heaters can be slow to heat up a room compared to gas heaters.
Environmental Impact
The environmental impact of your heating system is an increasingly important consideration.
Greenhouse Gas Emissions
Gas Heating: Burning natural gas releases greenhouse gases, including carbon dioxide, which contribute to climate change. While natural gas is cleaner than some other fossil fuels, it still has a significant environmental impact. The extraction and transportation of natural gas can also lead to methane leaks, which is a potent greenhouse gas.
Electric Heating: The environmental impact of electric heating depends on the source of electricity. If your electricity comes from renewable sources like solar or wind, electric heating can be a very environmentally friendly option. However, if your electricity is generated from coal-fired power plants, electric heating can have a significant carbon footprint. As Australia transitions towards renewable energy, the environmental impact of electric heating is decreasing.
Energy Source Considerations
Consider the source of your energy when evaluating the environmental impact. If you have solar panels, electric heating can be a sustainable choice. If you are concerned about greenhouse gas emissions, electric heating powered by renewable energy is generally the better option.

Safety Considerations
Safety is paramount when choosing a heating system.
Carbon Monoxide Risk
Gas Heating: Gas heaters pose a risk of carbon monoxide poisoning if they are not properly maintained or ventilated. Carbon monoxide is a colourless, odourless gas that can be deadly. It is essential to have gas heaters regularly serviced by a qualified technician and to install carbon monoxide detectors in your home.
Electric Heating: Electric heaters do not produce carbon monoxide, making them inherently safer in this regard. However, they can pose a fire risk if they are used improperly or if they have faulty wiring. Always use electric heaters according to the manufacturer's instructions and ensure that your home's electrical system is in good condition.
Other Safety Factors
Gas Heating: Gas heaters can get very hot to the touch, posing a burn risk, especially to children and pets. Ensure that gas heaters are properly guarded and out of reach.
Electric Heating: Some electric heaters can also get hot, but many models have safety features like tip-over switches and overheat protection. Ensure that electric heaters are placed on a stable surface and away from flammable materials.
Suitability for Different Home Sizes
The size of your home is a crucial factor in determining the most suitable heating system.
Small Homes
Gas Heating: For small homes or apartments, gas space heaters can be a cost-effective option. They provide quick and efficient heating for a single room or area. However, ensure adequate ventilation.
Electric Heating: Electric space heaters are also suitable for small homes. They are portable and easy to use, making them a convenient option for heating individual rooms. Consider a reverse cycle air conditioner (heat pump) for heating and cooling.
Large Homes
Gas Heating: Ducted gas heating is well-suited for large homes, providing consistent and even heat distribution throughout the entire house. It can be more cost-effective than electric heating for large areas, especially if gas prices are lower than electricity prices in your area.
Electric Heating: Ducted electric heating or heat pumps can also be used in large homes. Heat pumps offer the advantage of providing both heating and cooling, making them a versatile option for year-round comfort. Consider zoning your heating system to improve efficiency.
Ultimately, the best heating system for your home depends on your specific needs and circumstances. Consider the factors outlined above – cost, energy efficiency, environmental impact, safety, and home size – to make an informed decision that will keep you comfortable and warm throughout the cooler months.
