A Melbourne homeowner in Werribee upgraded their old gas hot water system for a 320L Neopower heat pump. Thanks to $1,234 in government rebates, they only paid $2,450 out of pocket. If they’d replaced it with another gas system instead, they wouldn’t have gotten any rebate at all \u2014 gas systems don’t qualify. This guide breaks down the real differences between the two technologies using actual 2026 numbers, not gas company marketing, so you can make an informed decision.<\/p>\n\n\n\n

Why Victorian Rebates Favour Heat Pumps<\/h2>\n\n\n\n

Neither the federal STC scheme nor Victoria’s VEU program provides rebates when you replace one gas hot water system with another. Both programs specifically support the replacement of gas appliances with high-efficiency electric alternatives. On the Werribee 320L Neopower installation, the homeowner received 18 STCs at $38 each ($684)<\/strong> under the federal scheme plus $550 in VEECs<\/strong> under the VEU program \u2014 a combined $1,234 applied as a price reduction with zero government paperwork required from the homeowner.<\/p>\n\n\n\n

If you replace a broken gas hot water system with another gas unit, you receive nothing. If you upgrade to a VEU-eligible heat pump through a VEU Approved provider, you receive both rebates automatically.<\/p>\n\n\n\n

Running Costs: The Long-Term Difference<\/h2>\n\n\n\n

Heat pumps use ambient air to heat water rather than burning gas directly. A typical heat pump operates at a Coefficient of Performance (COP) of 3\u20134, meaning it produces 3\u20134 units of heat energy for every 1 unit of electricity consumed. A gas hot water system converts approximately 80\u201390% of the gas burned into useful heat \u2014 it cannot exceed 1:1. For Melbourne homeowners with rooftop solar already installed, running the heat pump during daytime generation hours can reduce the effective operating cost further, since you’re heating water from your own generation rather than the grid.<\/p>\n\n\n\n

What About Installation Complexity?<\/h2>\n\n\n\n

Switching from gas hot water to a heat pump involves more than a tank swap. The old gas unit must be safely decommissioned \u2014 the gas line capped, the tank permanently rendered inoperable, and the unit removed and recycled. Electrical connections are required for the new heat pump. GES coordinates all trades \u2014 electrical, plumbing, and gasfitting \u2014 as part of the complete upgrade. On the Werribee 320L heat pump installation<\/a>, all of this was included in the single all-in price of $3,684 before rebates, reducing to $2,450 after the $1,234 government rebate.<\/p>\n\n\n\n

Heat Pump Installation in Melbourne – Frequently Asked Questions<\/h2>\n\n\n\n

Is a heat pump hot water system better than gas in Melbourne in 2026?<\/strong><\/p>\n\n\n\n

For most Melbourne homeowners replacing an existing gas system, a heat pump offers three advantages gas cannot match: up to $1,234 in government rebates (18 STCs at $38 = $684 plus $550 VEECs on a documented 2026 install), 3\u20134\u00d7 greater running efficiency (COP 3\u20134 vs gas at under 1:1), and compatibility with rooftop solar. Gas replacements attract no VEU or STC rebate.<\/p>\n\n\n\n

Can I still install a gas hot water system in Victoria in 2026?<\/strong><\/p>\n\n\n\n

Existing gas hot water systems can be replaced on a like-for-like basis in most Victorian properties in 2026, but replacement gas systems attract no government rebates. Victoria’s electrification policy increasingly supports switching away from gas appliances, and the VEU and STC programs provide financial incentives only for electric upgrades such as heat pumps.<\/p>\n\n\n\n

How much cheaper is a heat pump to run than gas hot water in Melbourne?<\/strong><\/p>\n\n\n\n

Heat pumps typically operate at COP 3\u20134, producing 3\u20134 units of heat per unit of electricity. Gas systems convert roughly 80\u201390% of fuel to heat. Actual savings depend on your electricity tariff, gas price, and usage patterns. Homeowners with existing rooftop solar can reduce operating costs further by scheduling heat pump operation during solar generation hours.<\/p>\n\n\n\n

Do I need to decommission my gas system when switching to a heat pump?<\/strong><\/p>\n\n\n\n

Yes. A gas-to-heat-pump upgrade requires professional decommissioning of the old gas unit \u2014 the gas line must be capped, the tank permanently rendered inoperable (typically by drilling), and the old unit removed and recycled. GES includes gas decommissioning as part of the complete upgrade, coordinating all electrical, plumbing, and gasfitting trades in a single project.<\/p>\n\n\n\n

Is Green Electric Solutions a VEU Approved provider for heat pump hot water?<\/strong><\/p>\n\n\n\n

Yes. GES is a VEU Approved provider, which is the accreditation required to apply Victorian VEU VEEC rebates directly to your heat pump installation cost. GES also manages federal STC creation and trading. Both rebates are applied as a direct price reduction with no government paperwork from the homeowner.<\/p>\n\n\n\n
