Ducted Gas vs Reverse Cycle: Heating Options in Melbourne 2026

If your gas ducted heating system is operational but emitting unusual sounds, or if you’ve observed a spike in your energy bills, you might be considering an upgrade. Are you deliberating between gas and reverse cycle heating for your Melbourne home in 2026? Let’s explore these heating solutions in a straightforward manner, enabling you to make a well-informed decision.

Explore Melbourne’s Heating Regulations and Their Implications in 2026

From January 1, 2024, the Victorian Government will enforce a gas ban on new residential developments. This regulation mandates that any new homes requiring planning permits cannot connect to mains gas and must instead utilise all-electric systems. The initiative is managed by the Victorian Department of Energy, Environment and Climate Action and applies statewide. For further details on this policy, please visit the Energy Victoria website.

Here’s how this policy influences current and prospective homeowners:

• If your home already uses gas: You do not need to make immediate changes. You can continue using your current ducted gas system, replace it with another gas unit when it wears out, or choose to switch to reverse cycle heating at your convenience.
• If you’re building a new home: You must adopt an all-electric approach. Reverse cycle heating and cooling has become the norm for all new constructions.
• If you plan significant renovations that involve new gas lines: Consultation with your builder is vital, as some councils are enforcing restrictions on new gas installations, even in existing homes.

Discover the Benefits of Ducted Gas Heating for Melbourne Homes

Ducted gas heating continues to be a practical choice for many households in Melbourne, offering numerous advantages:

• Quick heating: Gas burners reach their operational temperature rapidly. In comparison, reverse cycle systems may take longer to heat up, especially on chilly mornings when your home has been cold overnight.
• Consistent heat distribution: Well-designed ductwork guarantees that heat is evenly spread throughout your home, ensuring comfort in every room.
• Efficiency in extreme cold: Gas systems perform effectively even when temperatures drop significantly outside. While modern reverse cycle units operate adequately in Melbourne’s coldest conditions, gas systems maintain a clear advantage.
• Utilisation of existing infrastructure: If your ductwork, controls, and gas lines are in good shape, replacing your gas unit with another ducted gas heater is generally more cost-effective and can often be completed in a single day, compared to switching to a reverse cycle system.

Evaluate the Advantages of Reverse Cycle Systems Compared to Ducted Gas Heating

• Dual heating and cooling: A reverse cycle system offers warmth in winter and cooling in summer, eliminating the need for a separate cooling system, unlike ducted gas heating.
• Reduced operational costs: Modern reverse cycle systems are exceptionally efficient, producing three to five units of heat for every unit of electricity consumed, a level of efficiency that gas systems cannot match.
• No combustion emissions: Reverse cycle systems mitigate the risks associated with gas combustion, including the need for flues and concerns regarding carbon monoxide safety.
• Improved zoning capabilities: Many contemporary reverse cycle systems allow for individual heating or cooling of specific rooms, preventing unnecessary heating in unoccupied areas.
• Future-proof investment: With gas prices in Victoria steadily increasing over the past five years, reverse cycle systems offer protection against rising energy costs.

In-Depth Comparison of Running Costs for a Typical Three-Bedroom Home in Melbourne

The following are realistic annual running cost estimates for a standard three-bedroom home in Melbourne in 2026, assuming average occupancy:

• Annual running cost for ducted gas: This can range from $1,200 to $2,000, depending on usage patterns, energy rates, and the efficiency of the heating unit.
• Annual running cost for ducted reverse cycle: This usually falls between $700 and $1,400 for units rated five stars or higher.
• Cost savings: Households can anticipate saving between $400 and $800 annually by making the switch, not accounting for the additional cooling provided by a reverse cycle system.

It is important to note that homes with insufficient insulation, oversized spaces, or extensive glass features may incur higher costs within these estimates, regardless of the heating system selected. Tackling draughts, insulating ceilings, and implementing effective zoning strategies can have a more significant impact on your energy bills than the choice of heating system.

Recognise Scenarios Where Ducted Gas Heating Is Still a Suitable Option

• If your current gas system is under 10 years old and functioning well: You may replace it with a similar unit when it eventually fails, ensuring continued efficiency.
• If your home has limited electrical capacity: Older properties with low-amperage supplies may require a switchboard upgrade to accommodate a ducted reverse cycle system, potentially increasing the overall transition cost.
• If you live in a particularly cold area of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may face challenges. Assessing your specific home conditions is crucial rather than relying solely on general advice.
• If you require heating only without cooling: A new ducted gas unit typically has a lower initial cost compared to a ducted reverse cycle system. If cooling is not a priority, gas may remain the more economical choice.

Understand When Reverse Cycle Systems Are the Optimal 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 include cooling capabilities now rather than retrofitting later.
• If you’re seeking to eliminate separate summer cooling costs: Transitioning from multiple systems, such as split units or evaporative cooling, to a single ducted reverse cycle system simplifies your setup and reduces overall expenses.
• If you’re renovating or expanding your home: Installing new ductwork at this stage allows for a well-designed system rather than a makeshift solution.
• If you desire lower energy costs: Reverse cycle systems consistently outperform ducted gas regarding running costs in Melbourne, with the gap widening.
• If future resale value is a consideration: Potential buyers are increasingly prioritising energy efficiency and cooling options, where reverse cycle systems excel.

Address Common Questions About Heating Options in Melbourne

Is Gas Heating Being Phased Out in Victoria?

No, existing homes are not affected. As of January 1, 2024, new residential constructions requiring planning permits are banned 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 live in an existing home already connected to gas, you can replace a faulty ducted gas unit with a new one. The installation must be carried out by a licensed gas fitter in accordance with AS/NZS 5601 gas installation standards, but it is not impacted 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 good condition, the installation of a ducted reverse cycle system starts at approximately $5,500 and can exceed $15,000 for larger homes with multiple zones or high-end units. If an upgrade to your switchboard is necessary to manage the load, you should anticipate an additional expense 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 Operate Efficiently During Melbourne Winters?

Yes — modern reverse cycle units are designed to work effectively at temperatures as low as minus five degrees Celsius, which is suitable for Melbourne’s coldest mornings. Although efficiency may decrease in extreme cold compared to gas, the difference for most Melbourne homes is minimal. Proper sizing of the unit based on your home’s heating requirements is more crucial than merely the choice of system.

Will Transitioning to Reverse Cycle Result in Real Savings?

Most households in Melbourne can expect to save between $400 and $800 annually 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’re currently maintaining separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the costs associated with a second system.

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

Yes — a licensed gas fitter is required to disconnect and safely cap the old gas line, while a licensed electrician will manage the electrical setup for the new reverse cycle unit and any necessary switchboard upgrades. Beyond coordinates both trades as part of a comprehensive installation, so you won’t need to juggle multiple contractors. Gas disconnection must be performed by a Type A gas fitter in compliance with Energy Safe Victoria regulations.

What Is the Typical Timeline for Installing a Reverse Cycle Ducted System?

For a standard three-bedroom home in Melbourne with existing ductwork, the entire installation typically takes one to two days. If replacement or reconfiguration of the existing ductwork is required, or if the switchboard needs upgrading, plan for a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
