The 3030 postcode, covering Werribee South, Chartwell, Cocoroc, Point Cook, Quandong and Werribee and surrounding areas, is home to around 41,811 households. With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Werribee South and the 3030 area, 18,173 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Werribee South's climate delivering an average of 4.2 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Werribee South
Across Werribee South and the wider 3030 area, more households are swapping old gas and electric units for an energy efficient hot water system. With average household sizes around 2.9 people and more than 38,000 dwellings in the postcode, hot water is a big slice of local energy use – and a smart place to start if you want lower bills and a more comfortable, all‑electric home.
The local climate is made for efficient hot water. At Werribee Racecourse the mean daily solar exposure averages about 15.2 MJ/m², which is roughly 4.2 kWh of sun energy per square metre per day over the year. That strong sunlight helps both a solar hot water system and a modern heat pump hot water system perform well, especially when paired with rooftop solar. With many families in the area and a median household income a bit over $2,000 per week, upgrading from an older gas or electric hot water system is a logical next step to keep running costs under control while cutting emissions.
In 3030 there’s a mix of separate houses and townhouses, plus a growing number of units, so there’s no single “best hot water system Australia” wide – the right fit depends on your roof space, budget and whether you want to move away from gas. For some homes, a roof‑mounted solar hot water heating system with a ground tank makes sense; for others, a compact heat pump hot water system in the side yard or a modern electric hot water system controlled to run on solar power is the better option.
Locally, we see strong interest in brands like Rheem and Rinnai for solar hot water installation and solar hot water tank replacement, along with premium heat pump options such as Sanden and efficient units from EvoHeat. Many homeowners ask about heat pump vs solar hot water, or solar hot water vs electric hot water, and how each stacks up for comfort, reliability and long‑term savings. Done properly, a heat pump hot water installation can cut hot water energy use by up to two‑thirds compared with an old electric hot water system, while a well‑designed rheem solar hot water or rinnai solar hot water setup can be one of the most efficient hot water system choices when you have good sun and roof space.
To give you a feel for savings, here are typical annual bill reductions for Werribee South homes (actual hot water system price / cost will vary by brand and size):
• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas to heat pump hot water: save around $250–$600 per year. • Gas to solar hot water system: save about $200–$550 per year. • Old electric to modern electric hot water installation with solar PV control or diversion: save roughly $200–$500 per year.
These savings are even better if you already have solar and can time your hot water to run in the middle of the day. That is where a heat pump hot water system or efficient electric hot water system really shines as an energy efficient hot water system.
Werribee South and the broader 3030 area have already seen 18,173 efficient hot water systems installed, including both heat pump and solar hot water installations. Installations really took off from 2006, peaking between about 2009 and 2019 when many households embraced electrification and lower running costs. While yearly numbers have eased back a little since 2020, there is still steady demand for hot water installation and hot water repair as older units reach the end of their life and people look to future‑proof their homes.
When it comes to hot water VIC incentives, Werribee South residents can usually access a mix of Federal and State support. At the Federal level, eligible heat pump and solar hot water systems create Small‑scale Technology Certificates (STCs) that are often taken off the invoice as an upfront discount. On top of that, the Victorian hot water rebate VIC programs can offer a heat pump hot water rebate or solar hot water rebate that further lowers the heat pump hot water price / cost or solar hot water price / cost. There are also schemes that support efficient electric hot water installation, including an electric hot water system rebate when replacing old, inefficient units.
For many Werribee South homes, these hot water rebate VIC offers and STCs together can reduce the installed system cost by a substantial percentage, sometimes trimming thousands off a premium system like a sanden heat pump or a high‑performance chromagen solar hot water system. With lower upfront costs and ongoing bill reductions often in the hundreds of dollars per year, the payback period for a hot water upgrade can drop to just a few years, particularly if you also use timers or solar diversion to run your system when your panels are producing.
If your current unit is old, noisy, running out of hot water or needing frequent hot water repair, it is worth checking your options before it fails. Whether you are considering electric hot water vs gas hot water, weighing up heat pump vs solar hot water, or simply want the most efficient hot water system your budget allows, now is a good time to explore a hot water upgrade in Werribee South.
