Published 2026-05-03 · 3 min read

Explore the differences between split system and gas heating to find the best option for your home.

When it comes to keeping your home warm during the chilly Australian winters, choosing the right heating system is crucial. Two popular options are split system heating and gas heating. Both have their advantages and disadvantages, making it essential for homeowners to weigh their options carefully. In this article, we will explore the differences between these two heating systems to help you make an informed decision.

Understanding Split System Heating

Split system heating is an energy-efficient solution that consists of an outdoor unit and an indoor unit. These systems can provide both heating and cooling, making them a versatile choice for Australian homes. They work by extracting heat from the outside air and transferring it indoors, even in cooler temperatures.

Advantages of Split System Heating

Energy Efficiency: Split systems typically have a high energy rating, making them more efficient than traditional heating methods.
Cost-Effective: While the initial installation cost may range from AUD 1,500 to AUD 3,500, the long-term energy savings can offset this expense.
Temperature Control: Many split systems come with programmable thermostats, allowing for precise temperature control.
Space Saving: The compact design of split systems means they can fit into smaller spaces without taking up much room.

Exploring Gas Heating

Gas heating is another popular option for Australian homeowners. This system uses natural gas to generate heat and can come in various forms, including central heating and wall-mounted units.

Advantages of Gas Heating

Rapid Heating: Gas heaters provide almost instant heat, making them ideal for quickly warming up a room.
Lower Operating Costs: Gas is often cheaper than electricity, which can result in lower ongoing costs.
Reliable Performance: Gas heating systems are known for their reliability, especially during power outages.
Good for Large Spaces: Gas heating can effectively warm larger areas, making it suitable for big homes.

Comparing Costs: Split System vs. Gas Heating

Cost is a significant factor when choosing between split system heating and gas heating. Here’s a breakdown of potential costs:

Split System Installation: AUD 1,500 - AUD 3,500
Gas Heater Installation: AUD 1,000 - AUD 2,500
Annual Running Costs: Split systems can range from AUD 300 - AUD 600, while gas heating can be around AUD 200 - AUD 400 annually.

Keep in mind that these costs can vary based on the size of your home and the specific systems you choose.

Maintenance Requirements

Both heating systems require regular maintenance to ensure they operate efficiently.

Split System: It’s recommended to clean the filters every few months and have a professional service the unit annually.
Gas Heating: Annual servicing is essential to check for gas leaks and ensure safe operation.

Environmental Impact

Considering the environmental impact of your heating choice is vital. Split systems generally have a lower carbon footprint compared to gas heating, especially if powered by renewable energy sources. However, gas heating can still be a viable option when natural gas is sourced responsibly.
