Full gas meter abolition and high-efficiency reverse cycle heat pump conversion for a 4-bedroom family home in Geelong, Victoria.
- ✓ A standard 3-star ducted gas heater loses 35% to 45% of its consumed energy out the exhaust flue and through unsealed underfloor duct joins.
- ✓ Reverse-cycle electric heat pumps operate at COP 4.2 to 4.8, generating over 4 units of thermal warmth for every 1 unit of electrical energy consumed.
- ✓ Abolishing your gas meter permanently eliminates the mandatory daily gas supply charge, saving $380 to $440 per year before burning a single megajoule of gas.
- ✓ Our audited Melbourne family slashed their combined winter energy bills from $1,420/quarter down to $310/quarter by pairing heat pump climate control with rooftop solar.
1. The Economic Trap of Victorian Residential Gas in 2026
For four decades, Victorians were conditioned to believe that "Gas is Good" and gas ducted heating was the gold standard of winter warmth. In 2026, the thermodynamic and economic reality has flipped completely.
Driven by LNG export parity pricing on the Australian East Coast and declining production from the Gippsland Basin, domestic gas tariffs have escalated dramatically. Victorian retail gas tariffs now sit between $0.038 and $0.048 per Megajoule (MJ) on peak winter blocks. To heat a standard 4-bedroom home, an 80 MJ/h furnace running 6 hours a day burns $18.24 to $23.04 worth of gas per day.
Adding insult to injury is the unavoidable Daily Supply Charge: a fixed standing fee of $1.05 to $1.25 per day ($383 to $456 annually) simply for having a physical gas pipe connected to your property, even during mild months when heating is switched off.
2. Real 12-Month Geelong Household Bill Audit
Below is the verified, unedited billing audit from a family of four in Geelong, Victoria (28-square single-storey brick home). In April 2025, they disconnected their 18-year-old 3-star gas ducted heater and gas storage hot water, replacing them with a multi-split reverse cycle inverter system and an Emerald 270L heat pump:
| Quarterly Billing Period | Gas & Electric (Before) | All-Electric + Solar (After) | Net Quarterly Savings |
|---|---|---|---|
| Q1 (Summer: Jan – Mar) | $480 Elec + $140 Gas ($620) | $42.00 (Solar feed-in credit offset) | Save $578.00 |
| Q2 (Autumn: Apr – Jun) | $510 Elec + $420 Gas ($930) | $185.00 | Save $745.00 |
| Q3 (Winter: Jul – Sep) | $610 Elec + $810 Gas ($1,420) | $310.00 | Save $1,110.00 |
| Q4 (Spring: Oct – Dec) | $490 Elec + $220 Gas ($710) | $80.00 | Save $630.00 |
| TOTAL ANNUAL RUNNING COST | $3,680.00 / yr | $617.00 / yr | SAVE $3,063.00 / YR |
3. Thermodynamics: Star Ratings vs Coefficient of Performance (COP)
Why is the operational cost difference so astronomical? The answer lies in basic thermodynamics:
Gas creates heat by burning methane fuel. Even a premium 5-star gas heater cannot exceed 85% thermal efficiency (1.0 MJ of chemical gas fuel yields at most 0.85 MJ of heat, with the remaining 15% vented outside as water vapour and CO2). A 3-star heater is lucky to hit 60% real-world efficiency after duct losses.
A heat pump does not create heat through combustion; it operates a refrigeration cycle in reverse, harvesting ambient thermal energy from outdoor air and concentrating it inside. At a COP of 4.5, 1 kilowatt-hour (3.6 MJ) of electricity moves 4.5 kilowatt-hours (16.2 MJ) of thermal heat into your home. It is over 500% more efficient than a gas burner.
4. How to Legally & Safely Abolish Your Gas Meter
To eliminate the $400/yr daily supply fee permanently, you must complete full Gas Meter Abolishment rather than simple temporary disconnection:
- Electric Conversion: Ensure all gas appliances (ducted heater, hot water, cooktop) are converted to electric heat pumps or induction.
- Plumber Capping: A licensed plumber isolates and caps the internal gas consumer piping, issuing a VBA Compliance Certificate.
- Abolishment Request: Submit an abolishment service order through your gas energy retailer (Origin, AGL, EnergyAustralia, etc.).
- Distributor Physical Removal: Your distribution network service provider (Jemena, Multinet Gas, or AusNet) sends a technician to physically dig up the service tee, remove the meter, and permanently purge the connection.
5. Indoor Air Quality & Pediatric Respiratory Health
Beyond the thousands of dollars in bill savings, eliminating gas ducted heating and gas cooktops has profound health benefits. Research published by the Medical Journal of Australia (MJA) and the National Asthma Council indicates that cooking and heating with unvented or poorly-vented gas appliances is responsible for up to 12% of childhood asthma burden in Australia: a health risk comparable to passive cigarette smoking indoors.
Combustion releases nitrogen dioxide (NO2), carbon monoxide (CO), and carcinogenic benzene directly into indoor living spaces. Transitioning to all-electric reverse cycle filtration and heat pump technology purifies your home's air while slashing operating costs.
Frequently Asked Questions
Q: Does gas heat feel 'warmer' than heat pump air conditioning?
Older early-generation AC units blew tepid 32°C air. Modern reverse-cycle inverter systems deliver supply air at 45°C to 50°C within minutes of turning on, with continuous thermostatic modulation that maintains a rock-solid room temperature rather than the harsh hot-and-cold cycling of gas furnaces.
Q: What does it cost to have the gas meter removed?
Victorian gas distribution network providers charge between $65 and $220 for permanent meter abolishment. This one-time fee pays for itself in less than 4 months of avoided daily supply charges.
Q: Can I keep my gas cooktop and only replace the heating?
You can, but you will still be forced to pay the $400/yr daily supply charge. Upgrading to a fast, responsive induction cooktop allows you to abolish the meter completely and pocket the full $400 annual standing fee saving.
