Is There an Electric Replacement for Gas Ducted Heating? – Climate Green Melbourne Answers Your Questions

 With energy prices increasing and sustainability becoming a top priority, many Victorian homeowners are shifting away from traditional gas ducted heating. Modern electric heating systems — especially reverse-cycle heat pumps — have rapidly become the preferred replacement due to their efficiency, safety, and long-term cost benefits.

In this Climate Green Melbourne guide, we take an updated look at whether electric heating can fully replace gas ducted heating, how both systems work, and why electric heating is becoming the smarter choice across Victoria.

Why Gas Ducted Heating Is Falling Out of Favour

Gas ducted heating has been common in Melbourne homes for decades, but the drawbacks are becoming more noticeable:

  • Soaring gas prices

  • Higher environmental impact

  • Carbon monoxide and gas leak risks

  • Increased servicing requirements

  • Limited zoning flexibility

At the same time, the Victorian Government is investing heavily in programs that encourage households to transition from gas to electric appliances — making the switch financially attractive.

How Gas Ducted Heating Works

Gas ducted heating warms your home using natural gas or LPG as fuel. The process is straightforward:

1. Burner Ignition

Gas is ignited inside a combustion chamber.

2. Heat Exchanger

The burner heats a metal exchanger that absorbs and transfers heat.

3. Fan Unit

Indoor air is drawn through the exchanger, heated, and circulated throughout the house.

4. Ducting System

Warm air travels through ceiling or underfloor ducts connected to each room.

5. Vent Outlets

Heated air is released through ceiling, wall, or floor vents.

6. Thermostat

Automatically regulates heat output by switching the system on and off.

7. Flue Pipe

Expels combustion gases (CO₂, moisture, etc.) outdoors.

While effective, the system relies on burning fossil fuels and needs regular maintenance to ensure safe operation.

Why Electric Heating Is Becoming the Top Alternative

Electric heating — particularly reverse-cycle heat pumps — offers a far cleaner and more efficient approach to heating your home. These systems use electricity instead of burning gas, making them safer and significantly cheaper to run.

Climate Green installs high-performance electric heating systems throughout Melbourne, Bendigo, Geelong, Ballarat, and nearby regions, ensuring homeowners benefit from expert, accredited installation and available rebates.

How Reverse-Cycle Electric Heating Works

Heat pump technology functions by transferring heat rather than creating it.

1. Heat Extraction

The system draws heat from outdoor air — even in winter.

2. Refrigerant Cycle

A refrigerant absorbs heat, is compressed, and then releases the heat inside the home.

3. Compressor

Increases the temperature of the refrigerant.

4. Outdoor Condenser

Either gathers or expels heat depending on the mode.

5. Reversing Valve

Switches the system between heating and cooling.

6. Indoor Coil & Fan

Releases warm air and keeps your home comfortable.

Because of this efficient transfer process, heat pumps can produce 3–5 units of heat for every unit of electricity used — making them one of the most energy-efficient heating systems available.



Benefits of Switching to Electric Heating

✔ More Environmentally Friendly

Electric heating produces no on-site emissions, helping reduce your home’s overall carbon footprint.

✔ Superior Efficiency

Heat pumps can achieve up to 400% efficiency, meaning lower running costs compared to gas.

✔ Reduced Operating & Maintenance Costs

No combustion means fewer parts, fewer breakdowns, and cheaper long-term upkeep.

✔ Enhanced Safety

No gas lines, no flames, and no carbon monoxide risk.

✔ Zoning & Precision Control

Heat the rooms you need without wasting energy on unused areas.

✔ Dual Heating & Cooling

One system provides both heating for winter and cooling for summer.

Potential Drawbacks to Consider

• Higher Initial Investment

Upfront installation costs may be higher, but Victorian rebates significantly reduce overall expenses.

• Electricity Tariffs

Running costs vary based on electricity rates, though these can be offset with solar and battery systems.

• Ductwork Compatibility

Most gas ducted ducts cannot be reused — split or multi-split heat pumps are typically recommended.

Available Rebates for Switching to Electric

Victorians may qualify for a range of rebates, including:

  • Victorian Energy Upgrades (VEU)

  • Electric Heating & Cooling Rebates

  • Solar Victoria incentives

As an accredited provider, Climate Green manages all compliance and paperwork so homeowners receive the maximum savings.

Final Verdict: Can Electric Heating Replace Gas Ducted Heating?

Absolutely.
Electric heating — particularly heat pump systems — is cleaner, cheaper to run, safer, and far more efficient than gas ducted heating. When combined with solar energy and supported by current government rebates, the benefits are even greater.

Switching to electric is one of the most impactful upgrades homeowners can make for comfort, efficiency, and sustainability.
