Ducted Gas and Reverse Cycle: Melbourne’s Heating Options for 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 whether an upgrade is necessary. Are you weighing the benefits of gas versus reverse cycle heating for your Melbourne home in 2026? Let’s explore these heating solutions in detail, empowering you to make a well-informed decision.

Explore Melbourne’s Heating Regulations and Their Implications for 2026

Starting January 1, 2024, the Victorian Government has introduced a gas ban for new residential buildings. This regulation mandates that any new homes requiring planning permits cannot connect to mains gas and must instead utilise all-electric systems. This initiative falls under the purview of the Victorian Department of Energy, Environment and Climate Action and applies statewide. For extensive policy information, please visit the Energy Victoria website.

Here’s how this policy impacts homeowners:

• For homes currently using gas: No immediate changes are necessary. You can continue utilising your existing ducted gas system, replace it with another gas unit upon its eventual failure, or opt to transition to reverse cycle heating at your convenience.
• For new home constructions: You will be required to implement an all-electric approach. Reverse cycle heating and cooling has become the standard for all new builds.
• For major renovations involving new gas lines: It is critical to consult your builder, as several 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 remains a practical option for many households in Melbourne, providing several significant advantages:

• Quick heating: Gas burners can reach their operational temperature swiftly. In contrast, reverse cycle systems may take longer to heat, especially on chilly mornings after a cold night.
• Even heat distribution: Properly designed ductwork ensures that heat circulates evenly throughout your home, ensuring comfort in every room.
• Effective in extreme cold: Gas systems operate efficiently even during significant drops in outdoor temperatures. While modern reverse cycle units perform adequately in Melbourne’s coldest temperatures, gas systems maintain a distinct edge.
• 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 generally more cost-effective and can often be completed in a single day compared to transitioning to a reverse cycle system.

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

• Dual heating and cooling: A reverse cycle system provides warmth in winter and cooling in summer, removing the necessity for a separate cooling system, unlike ducted gas.
• Reduced operational costs: Modern reverse cycle systems are exceptionally efficient, generating 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 eliminate 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 enable individual heating or cooling of specific rooms, avoiding unnecessary energy use in unoccupied spaces.
• Future-proof investment: With gas prices in Victoria steadily increasing over the past five years, reverse cycle systems offer protection against rising energy costs.

Comprehensive Cost Comparison for a Standard Three-Bedroom Home in Melbourne

Here are realistic annual running cost estimates for a typical 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, influenced by usage patterns, energy rates, and the efficiency of the heating unit.
• Annual running cost for ducted reverse cycle: This typically ranges from $700 to $1,400 for a unit 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 summer cooling provided by a reverse cycle system.

It is crucial to note that homes with poor insulation, oversized spaces, or extensive glass features may incur higher costs within these estimates, regardless of the heating system selected. Addressing draughts, improving ceiling insulation, and implementing effective zoning strategies can significantly affect your energy bills more than the choice of heating system.

Recognise When Ducted Gas Heating Remains a Practical Option

• If your current gas system is under 10 years old and functioning effectively: You may replace it with a similar unit when it eventually fails, ensuring continued efficiency.
• If your home has limited electrical capacity: Older homes 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 encounter challenges. Evaluating your specific home conditions is essential, rather than relying solely on general advice.
• If you require heating only without cooling: A new ducted gas unit usually has a lower initial cost compared to a ducted reverse cycle system. If cooling is not a priority, gas may still prove to be the more economical choice.

Identify Scenarios Where Reverse Cycle Systems Are the Superior 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’re weary of separate cooling costs in summer: 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 time enables a well-designed system rather than a makeshift solution.
• If you seek to lower energy costs: Reverse cycle systems consistently outperform ducted gas in terms of running costs in Melbourne, with the gap widening.
• If future resale value is a consideration: Potential buyers increasingly favour energy efficiency and cooling options, where reverse cycle systems excel.

Address Frequently Asked 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 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 opt for 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 already connected to gas, you can replace a malfunctioning ducted gas unit with a new one. The installation must be performed by a licensed gas fitter in accordance with AS/NZS 5601 gas installation standards, but it is not affected by the bans on new constructions.

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

For a typical three-bedroom home in Melbourne with existing ductwork in acceptable condition, installing 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 needed to handle the load, you should anticipate 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 begins.

Do Reverse Cycle Systems Function Efficiently During Melbourne Winters?

Yes — modern reverse cycle units are engineered to operate efficiently at temperatures as low as minus five degrees Celsius, which is adequate for Melbourne’s coldest mornings.
