Converting from gas to electric, often called home electrification, means replacing gas appliances such as hot water systems, cooktops, heaters, and dryers with efficient electric alternatives. For many Sydney homes, the biggest wins are a heat pump hot water system, an induction cooktop, and reverse-cycle air conditioning for heating and cooling.
A gas-to-electric conversion can reduce running costs, remove combustion appliances from the home, and make a property more compatible with solar and battery storage. NSW Climate and Energy Action says electric appliances generally cost less to run and maintain than gas, and estimates that an electrified NSW house or small business can save about $2,771 per year. However, the upfront cost, switchboard capacity, wiring, and appliance choices all need careful planning.
Russo Electrical can assess your switchboard, circuits, and appliance load before you replace gas appliances, helping ensure your home is electrically ready for the upgrade.
What Is a Gas-to-Electric Conversion?
A gas-to-electric conversion replaces gas-powered equipment with electric equipment. Depending on the home, this may involve replacing one appliance or converting the entire household.
Common conversions include:
A full conversion may also involve capping or removing the gas connection once no gas appliances remain.
Why Homeowners Are Switching
Lower Running Costs
Electric appliances, especially heat pumps and induction cooktops, are generally more efficient than their gas equivalents. NSW notes that hot water heating makes up around 29% of an average NSW energy bill, and that replacing an old gas hot water system with a heat pump or solar hot water system can save up to $800 a year.
A Victorian government example estimates that switching from gas hot water to an electric heat pump can reduce annual running costs from $1,916 to $361, while switching from a gas cooktop to induction can reduce annual cooking costs from $178 to $67.
Improved Safety and Comfort
Induction cooktops have no open flame or gas combustion, making them safer and easier to clean. They heat pots and pans directly using magnetic currents, and are around three times more energy efficient than gas cooking.
Heat pump hot water systems work like a reverse refrigerator, drawing heat from the air to warm water. They use significantly less electricity than traditional electric water heaters and can replace gas hot water systems.
Better Fit with Solar and Batteries
Electric appliances can be timed to use solar generation during the day, reducing reliance on grid electricity. Heat pump hot water systems, for example, can be scheduled to heat water when solar output is high.
For homes considering rooftop solar or battery storage, electrification can increase energy independence and reduce exposure to volatile fossil fuel prices.
Typical Conversion Costs
Costs vary widely depending on the appliances chosen, the condition of the switchboard, wiring requirements, and whether plumbing or gas-disconnection work is needed.
| Conversion | Indicative cost | Notes |
|---|---|---|
| Heat pump hot water system | $2,200-$6,800 | Often the highest-impact first upgrade. |
| Induction cooktop | $800-$5,000+ | Appliance cost varies widely by brand and features. |
| Induction cooktop supply and installation | $2,300-$3,000 | Includes installation in one Victorian government example. |
| Reverse-cycle air conditioning | About $5,000 | Typical cost before rebates, depending on system size. |
| Switchboard upgrade or extension | $500-$2,000 | Needed if the board lacks capacity or spare circuit space. |
| Full electrical work for conversion | $500-$2,500 | Includes dedicated circuits and possible switchboard work. |
| Full home electrification | $8,000-$16,000 before rebates | Covers hot water, heating, and cooking. |
| Whole-home gas-to-electric switch | $5,000-$15,000+ | Depends on appliances and electrical upgrades. |
Published indicative market ranges only, not a Russo Electrical quotation. Costs and rebates depend on property, appliance and installation scope.
One real-world example reported a homeowner paid about $13,000 after rebates to convert gas ducted heating, gas instantaneous hot water, and a gas cooktop to reverse-cycle air conditioning, a heat pump hot water system, and an induction cooktop, supported by a 6.6 kW solar system.
The Most Common First Upgrades
Heat Pump Hot Water
A heat pump hot water system is often the best first step because hot water is one of the largest household energy loads. NSW advises replacing old gas hot water systems with an electric heat pump or solar hot water system, both of which use less energy.
Typical heat pump costs range from $2,200 to $6,800, depending on capacity, brand, installation complexity, and location.
Induction Cooktop
Induction cooking is fast, precise, and efficient. Most induction cooktops are compatible with a standard household single-phase 240V supply, although the circuit and switchboard still need to be assessed.
A built-in induction cooktop can cost $800 to $5,000 or more, depending on the model. Installation may require a new dedicated circuit, especially if the existing gas connection did not previously support an electric cooktop.
Reverse-Cycle Air Conditioning
A reverse-cycle air conditioner provides both heating and cooling from one electric system. It can replace gas ducted heating or gas space heaters, though larger homes may need multiple systems or ducted electric solutions.
What Electrical Work Is Involved?
Gas-to-electric conversion is not only about buying new appliances. Each new electric appliance may need its own circuit, correct cable size, circuit protection, and switchboard capacity.
A heat pump hot water system, induction cooktop, and reverse-cycle air conditioner can each require a dedicated circuit. Before replacing multiple gas appliances, an electrician should check the household switchboard capacity, wiring, appliance load, and installer requirements.
Electrical work may include:
Hard-wired appliances must be installed by a licensed electrician, and upgrades can become expensive depending on the home’s layout, switchboard, and cabling needs.
Does Your Switchboard Need an Upgrade?
Not always, but it is one of the first things to check.
Your switchboard may need upgrading if it:
Whether a switchboard upgrade is needed depends on the existing electrical setup and the appliances being installed. If the switchboard has no spare circuit-breaker slots, an electrician may need to upgrade it; typical costs are about $500 to $2,000, depending on whether the board needs replacing or extending.
What About the Gas Connection?
Once all gas appliances have been replaced, you may choose to disconnect or cap the gas supply. This can remove ongoing gas supply charges, but the process and requirements depend on your gas retailer, network, and property setup.
Do not simply plug or cap a gas line yourself. Gas disconnection should be handled by an appropriately licensed gas professional, and electrical connections should be handled by a licensed electrician.
Is Electrification Worth It?
For many households, yes, especially when replacing ageing gas appliances anyway.
Electrification is most attractive when:
NSW guidance says electrification can lower overall energy costs across electricity, gas, and petrol while increasing property value. Switching fully to electricity, backed by solar and a battery, maximises savings and improves energy independence.
However, the financial case depends on your current gas usage, electricity tariff, solar access, appliance condition, and whether major switchboard or wiring upgrades are required.
How to Plan a Gas-to-Electric Conversion
1. Start with an Electrical Assessment
Before buying appliances, have a licensed electrician assess your switchboard, wiring, spare circuit capacity, and expected appliance loads.
2. Prioritise High-Impact Appliances
For most homes, the best order is:
3. Check Solar Potential
If you have solar, or plan to install it, consider whether appliances can be scheduled to use daytime solar generation. Heat pump hot water systems can be timed to use solar power.
4. Budget for Electrical Upgrades
Set aside a contingency for switchboard work, dedicated circuits, cable upgrades, or additional safety switches. A full conversion may require $500 to $2,500 in electrical work, including any switchboard upgrade.
5. Plan Appliance Replacement Timing
You do not need to convert everything at once. Many homeowners convert appliances progressively as they reach end of life, starting with hot water or heating.
Frequently Asked Questions
Do I need three-phase power for induction cooking?
Not usually. Most induction cooktops are compatible with a standard household single-phase 240V supply. However, the circuit, cable size, and switchboard capacity still need professional assessment.
Do heat pumps use a lot of electricity?
Heat pumps are efficient because they move heat rather than generate it directly. They typically draw about half the current of a standard toaster and can operate on a standard single-phase 240V supply on a dedicated circuit.
Can I convert gradually?
Yes. Many homeowners replace one gas appliance at a time, often starting with hot water or heating. An electrician can assess whether your switchboard and wiring can support staged upgrades.
Will I need a new switchboard?
Possibly. It depends on your existing switchboard condition, spare capacity, wiring, and the appliances being installed.
Is induction better than gas?
Induction is generally more energy efficient, faster, safer, and easier to clean because it has no open flame or gas combustion.
Final Thoughts
A gas-to-electric conversion can make a home safer, more efficient, and better prepared for solar and battery technology. The most common upgrades, heat pump hot water, induction cooking, and reverse-cycle air conditioning, can deliver meaningful running-cost savings, particularly when paired with solar.
The key is planning. Before replacing gas appliances, have a licensed electrician assess your switchboard, circuits, wiring, and appliance loads. Russo Electrical can help determine whether your home needs dedicated circuits, a switchboard upgrade, or other electrical work before your gas-to-electric conversion begins.
