Hot water accounts for roughly a quarter of the average Australian household's energy bill, yet most homes are still running outdated gas or electric resistance systems that waste enormous amounts of energy. Heat pump hot water systems offer a dramatically more efficient alternative, and with generous government rebates now available, thousands of Geelong and Surf Coast homeowners are making the switch. At Evo Solar, we've seen heat pump installations more than triple over the past year — and for good reason.
How Does a Heat Pump Work?
Unlike a traditional electric hot water system that uses a heating element to generate heat from scratch, a heat pump works by extracting heat from the surrounding air and transferring it into your water tank. Think of it like a reverse refrigerator — instead of pulling heat out of a box to keep it cool, a heat pump pulls heat from the outdoor air and concentrates it to heat water. Because the system is moving existing heat rather than creating it, a heat pump uses up to 80% less electricity than a conventional electric storage system. Even on cold Geelong winter mornings, modern heat pumps operate efficiently down to temperatures as low as -7 degrees Celsius.
Rebates That Make It Affordable
The upfront cost of a heat pump is higher than a basic electric system, but government incentives dramatically close that gap. Federal STCs (Small-scale Technology Certificates) provide a significant point-of-sale discount, typically worth $800 to $1,000 or more depending on your location and the unit's efficiency rating. On top of that, the Victorian Energy Upgrades (VEU) program offers additional incentives for replacing gas or electric resistance systems with an eligible heat pump. When you combine both programs, many homeowners find that a premium heat pump ends up costing a similar amount to a standard electric replacement — with a fraction of the running costs going forward.
Which Brands Are Worth Considering?
Not all heat pumps are created equal, and choosing the right unit for your home matters. At Evo Solar, we install and recommend several leading brands based on years of real-world performance in the Geelong climate. Reclaim Energy offers Australian-designed units with excellent efficiency ratings and quiet operation, making them ideal for homes where the unit sits near bedrooms. iStore is another popular choice, with an integrated design that replaces your existing tank in the same footprint. Rheem offers their AmbiHeat and AmbiPower ranges, which are widely available and well-supported. We'll help you choose the right capacity and model based on your household size, roof layout, and whether you have solar panels to run the heat pump during the day for maximum savings.
Why Geelong and Surf Coast Homeowners Are Switching
The shift away from gas hot water is accelerating across the Geelong region, driven by a combination of rising gas prices, new building regulations that favour all-electric homes, and growing awareness of how much energy traditional systems waste. For homes that already have solar panels, a heat pump is the perfect complement — you can schedule it to heat water during the middle of the day when your solar production is highest, effectively getting your hot water for free. Even without solar, the running cost of a heat pump is typically $100 to $200 per year compared to $500 to $800 for gas or $800 to $1,200 for a conventional electric system. Over the 10 to 15 year lifespan of the unit, that adds up to thousands of dollars in savings.
