Why More Melbourne Homes Are Replacing Gas Heating
Victorian homeowners are increasingly choosing to replace gas heating Melbourne for one simple reason: rising energy costs.
Gas prices across Victoria have increased substantially over recent years, while modern reverse-cycle systems have become dramatically more energy efficient.
Common reasons Melbourne families are upgrading:
- – Winter gas bills becoming unaffordable
- – Old gas systems breaking down frequently
- – Difficulty sourcing replacement parts
- – Wanting both heating and cooling in one system
- – Preparing for future electrification
- – Accessing government rebates before they change
Additionally, Victoria is actively encouraging households to move toward electric energy-efficient appliances through programs like Victorian Energy Upgrades.
According to Green User internal installation data, over 500+ Melbourne families upgraded their heating systems through rebate-supported installations in the last few years.
Many homeowners report feeling immediate relief after switching from ducted gas to efficient electric heating.
How VEU Rebates Reduce Your Upgrade Cost
The VEU rebate heating upgrade program helps eligible Victorian households reduce the upfront cost of replacing inefficient gas systems.
Under the Victorian Energy Upgrades scheme, accredited providers like Green User can help homeowners access discounts on approved energy-efficient heating systems.
What can the VEU rebate cover?
Depending on the system and eligibility, the rebate may reduce:
- Equipment costs
- Installation costs

Is It Worth Replacing Gas Heating in 2026?
For many Melbourne households, yes.
The combination of:
- rising gas prices,
- rebate support,
- lower electricity running costs,
- and modern energy-efficient systems
means replacing gas heating often makes financial sense long term.
Estimated Annual Savings
Many Victorian homeowners save between:
- $800–$1,500 per year on heating and cooling costs
depending on:
- insulation quality,
- household size,
- solar usage,
- and previous gas consumption.
Additionally, reverse-cycle systems are far more efficient than older ducted gas systems because they transfer heat rather than generate it through combustion.
Benefits beyond energy bills
Replacing ducted gas heating may also provide:
- Better indoor air quality
- Reduced carbon emissions
- Quieter operation
- More consistent temperature control
- Increased property appeal
For homeowners already considering solar, combining a heating upgrade with

can further reduce running costs.
Common Reasons Upgrades Get Delayed
Many homeowners wait too long because they assume:
- The upgrade will cost too much
- Rebates are difficult to access
- The process is complicated
- Their current system still “works”
However, delaying replacement often leads to:
- expensive emergency repairs,
- peak-winter installation delays,
- and higher ongoing gas bills.
At Green User, we regularly help households who initially postponed upgrades only to discover they qualified for substantial rebate support.
That’s why checking eligibility early is important — even if you’re not ready to install immediately.
