If your Melbourne home still uses gas ducted heating or gas wall heaters, you are almost certainly overpaying.

A modern reverse cycle air conditioner delivers 3 to 4 units of heat for every 1 unit of electricity used. In comparison, even the best gas heaters convert only 80–92% of gas into usable heat — and that’s before flue losses.

In simple terms:

• Gas heating = pay $1 → get ~$0.85–$0.92 worth of heat

• Reverse cycle heating = pay $1 → get ~$3–$4 worth of heat

With Victorian gas prices at record highs in 2026, the cost gap is wider than ever.

• Gas vs electric heating running costs Melbourne

• Should I replace gas heating in 2026?

• VEU rebate reverse cycle eligibility

How Heating Efficiency Actually Works (COP Explained)

The key concept is Coefficient of Performance (COP).

What is COP?

COP measures how much heat a system produces compared to the energy it consumes.

• A gas heater (90% efficient) has a COP of 0.9

• A reverse cycle air conditioner typically has a COP between 3.0 and 5.0

• Melbourne average: ~3.5 COP

Why Reverse Cycle Is More Efficient

Gas heaters create heat by burning fuel.

Reverse cycle air conditioners move heat from outdoor air to inside your home using refrigerant technology.

Moving heat uses far less energy than generating heat from combustion.

That’s why reverse cycle heating is:

• 3–4 times more efficient than gas

• Significantly cheaper per degree of warmth

• Lower emission

This isn’t a small improvement — it’s a completely different technology model.

Real Running Costs in Melbourne (2026 Data)

Average Melbourne Household Heating Costs

Potential Savings:

$700 – $1,300 per year

For homes replacing individual gas wall heaters:

• Save approximately $300–$400 per unit annually

• Replace 3 heaters → save $1,000+ per year

Over a 15-year system lifespan, that’s $15,000+ in savings.

And remember — reverse cycle includes cooling.

Why Gas Prices Keep Rising in Victoria

Many homeowners assume gas prices will fall. The evidence suggests otherwise.

Key Reasons:

• Bass Strait gas supply declining

• Increased reliance on interstate gas

• Wholesale gas prices linked to global LNG markets

• Export competition with Japan & South Korea

Victorian residential gas prices have increased 40–50% since 2019.

Energy analysts project continued pressure through 2030.

Electricity prices have also risen — but the 3–4x efficiency advantage of reverse cycle keeps it cheaper per unit of heat.

2027 Victorian Gas Regulations: What You Must Know

From 1 January 2027:

• New homes must be fully electric

• No new gas connections permitted

From 1 March 2027:

• Gas heaters & gas hot water systems must be replaced with electric alternatives at end-of-life

If your gas heater is 10+ years old, waiting could mean:

• Emergency winter replacement

• Higher installation demand

• Less system choice

Switching in 2026 means:

• Access to VEU rebates

• Planned installation

• No winter stress

The Summer Bonus Most Homeowners Forget

Gas heating only works in winter.

Reverse cycle provides:

• Heating in winter

• Cooling in summer

With Melbourne experiencing:

• More heatwaves

• Longer hot spells

• Higher summer electricity use

Installing reverse cycle replaces:

• Gas heater

• Portable AC units

• Future cooling installation costs

This shortens your real ROI significantly.

VEU Rebate 2026: How Much Can You Save?

The Victorian Energy Upgrades (VEU) program provides rebates when replacing gas heating with energy-efficient reverse cycle systems.

Current 2026 Estimated Rebates

• Replace ducted gas → Up to $5,000+ discount

• Replace gas wall heater → $800 – $2,500 per unit

• No income test

• No property value cap

The rebate is applied as an upfront discount — not a cashback.

This reduces installation costs immediately.

Rebate levels are reviewed periodically and may reduce as 2027 approaches.
