Ducted Gas and Reverse Cycle: Preferences of Melbourne Homeowners 2026

If your gas ducted heating system is operational yet emitting unusual sounds, or if you’ve noticed an increase in your energy bills, you might be considering a change. Are you trying to decide between gas heating and reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options comprehensively, without any sales jargon, to empower you to make a well-informed decision.

Navigate Melbourne's Heating Regulations and Anticipated Changes for 2026

Starting January 1, 2024, the Victorian Government has enacted a gas ban for new residential developments. This regulation stipulates that any new homes requiring planning permits must not connect to mains gas and should instead incorporate all-electric systems. The Victorian Department of Energy, Environment and Climate Action enforces this initiative statewide. For detailed information on this policy, please refer to the Energy Victoria website.

Here’s what this policy implies for homeowners:

• If your home currently uses gas: You are not required to implement any immediate changes. You can continue utilising your existing ducted gas system, replace it with another gas unit when it reaches the end of its lifespan, or choose to transition to reverse cycle heating at your convenience.
• If you are building a new home: You must adopt an all-electric approach. Reverse cycle heating and cooling is now the standard for all new constructions.
• If you are engaging in significant renovations that require new gas lines: It is essential to consult with your builder, as some councils are beginning to impose restrictions on new gas installations, even within existing homes.

Explore the Benefits of Ducted Gas Heating for Melbourne Homes

Ducted gas heating remains a practical choice for many households in Melbourne. Its advantages are substantial:

• Rapid heating: Gas burners reach their operational temperature quickly. In comparison, reverse cycle systems may take longer to warm up, especially during cold mornings when your home has been cool overnight.
• Reliable heat distribution: Well-designed ductwork ensures heat is evenly spread throughout your home, enhancing comfort in every room.
• Effectiveness in extreme cold: Gas systems maintain their efficiency even when external temperatures drop significantly. While modern reverse cycle units perform adequately in Melbourne’s coldest conditions, gas systems have a definitive advantage.
• Utilisation of existing infrastructure: If your ductwork, controls, and gas lines are in good condition, replacing your gas unit with another ducted gas heater is often a budget-friendly option and can typically be completed within a single day, unlike switching to a reverse cycle system.

Evaluate the Advantages of Reverse Cycle Systems Over Ducted Gas

• Combined heating and cooling: A reverse cycle system offers warmth in winter and cooling in summer, eliminating the need for a separate cooling system that ducted gas does not provide.
• Reduced operational costs: Modern reverse cycle systems boast high efficiency, producing three to five units of heat for each unit of electricity consumed, an efficiency level that gas systems find challenging to match.
• No combustion emissions: Reverse cycle systems mitigate the risks associated with gas combustion, negating the need for flues and alleviating concerns regarding carbon monoxide safety.
• Superior zoning capabilities: Many contemporary reverse cycle systems allow for individual room heating or cooling, preventing unnecessary energy use in unoccupied spaces.
• Future-proof investment: With gas prices in Victoria escalating over the past five years, reverse cycle systems offer a buffer against rising energy costs.

Annual Running Cost Comparison for a Typical Three-Bedroom Home in Melbourne

Below are realistic estimates for annual running costs for a standard three-bedroom home in Melbourne during 2026, assuming average occupancy:

• Annual running cost for ducted gas: Typically ranges from $1,200 to $2,000, depending on usage patterns, energy tariffs, and the efficiency of the unit.
• Annual running cost for ducted reverse cycle: Generally falls between $700 and $1,400 for units rated five stars or above.
• Cost savings: Households can expect to save between $400 and $800 annually by switching, not accounting for the additional summer cooling provided by a reverse cycle system.

It is important to recognise that homes with insufficient insulation, oversized rooms, or extensive glass features may experience higher costs within these ranges, regardless of the heating system chosen. Addressing draughts, insulating ceilings, and implementing effective zoning strategies can significantly impact your energy bills more than the choice of heating system.

Situations Where Ducted Gas Heating Remains a Strong Option

• If your current gas system is less than 10 years old and in good working condition: You can replace it with a similar unit when it eventually fails, retaining an efficient asset.
• If your home has limited electrical capacity: Older homes with low-amperage supplies might require a switchboard upgrade to support a ducted reverse cycle system, which can increase the overall transition costs.
• If you live in a particularly cold area of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may encounter challenges. It’s advisable to assess your specific home rather than relying solely on general information.
• If heating is your only requirement without cooling: A new ducted gas unit typically incurs a lower initial cost compared to a ducted reverse cycle system. If cooling is not necessary, gas might still be the more economical option.

Recognise When Reverse Cycle Systems Are the Best Choice

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its operational lifespan, making it more cost-effective to incorporate cooling capabilities now rather than retrofitting later.
• If you are fatigued by separate summer cooling costs: Transitioning from multiple systems like split units or evaporative cooling to a single ducted reverse cycle system simplifies your setup and reduces overall expenses.
• If you are renovating or expanding your home: Installing new ductwork at this stage allows for a well-designed system instead of a makeshift solution.
• If you aim for reduced energy costs: Reverse cycle systems consistently outperform ducted gas regarding running costs in Melbourne, and the gap is widening.
• If future resale value is a factor: Potential buyers increasingly prefer energy efficiency and cooling options, where reverse cycle systems excel.

Address Frequently Asked Questions About Heating Solutions in Melbourne

Is Gas Heating Being Phased Out in Victoria?

Not for existing homes. As of January 1, 2024, new residential constructions requiring planning permits are prohibited from connecting to mains gas and must transition to all-electric systems. Homes already connected to gas can continue using their systems, replace them with new gas appliances, or voluntarily choose electric systems. The ban specifically targets new builds, not renovations.

Can I Replace My Old Ducted Gas System with a New Gas Unit?

Yes — if you reside in an existing home that is already connected to gas, you can replace a failing ducted gas unit with a new one. The installation must be carried out by a licensed gas fitter in line with AS/NZS 5601 gas installation standards, but it is not affected by the bans on new constructions.

What Are the Costs Associated with Switching from Ducted Gas to Reverse Cycle in Melbourne?

For a typical three-bedroom home in Melbourne with existing ductwork in satisfactory condition, the installation of a ducted reverse cycle system begins at approximately $5,500 and can exceed $10,000 for larger homes with multiple zones or high-end units. If an upgrade to your switchboard is necessary to handle the load, expect an additional cost of $1,500 to $2,500. Beyond provides fixed-price quotes following a complimentary in-home assessment, ensuring no fluctuating estimates once the work commences.

Do Reverse Cycle Systems Perform Well During Melbourne Winters?

Yes — modern reverse cycle units are designed to operate efficiently at temperatures as low as minus five degrees Celsius, which is suitable for Melbourne's coldest mornings. While efficiency may diminish in extreme cold compared to gas, for the majority of Melbourne homes, the difference is minor. Proper sizing of the unit based on your home’s heating requirements is more critical than simply the choice of system.

Will Transitioning to Reverse Cycle Lead to Real Savings?

Most households in Melbourne can anticipate annual savings of between $400 and $800 on running costs when switching from ducted gas to ducted reverse cycle, assuming similar usage patterns. The potential savings could be even greater if you are currently using separate heating and cooling systems, as a single ducted reverse cycle unit can replace both, eliminating the costs associated with maintaining a second system.

Do I Need to Hire Both an Electrician and a Gas Fitter for the Transition?
