The 3030 postcode, covering Chartwell, Cocoroc, Point Cook, Quandong, Werribee and Werribee South 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 Chartwell 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 Chartwell'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.

Other census insights reinforce Chartwell's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Chartwell community is home to 13,789 couple families with children and 2,514 one-parent families, meaning a large proportion of households face substantial hot water demand. With 17,227 homes owned with a mortgage and 7,835 owned outright, many residents also have the homeownership and growing equity that make switching to efficient hot water systems a practical way to lower expenses.

Hot water systems in Chartwell
Across Chartwell and the wider 3030 area, more households are rethinking their old gas and electric hot water system in favour of efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an average household size of around 2.9 people and more than 38,000 occupied dwellings, reliable hot water is non‑negotiable – but so is keeping energy costs under control.
Chartwell’s mostly separate houses and young median age of 34 mean plenty of growing families with big morning and evening hot water demand. At the same time, mortgage repayments around $2,000 a month and solid but not unlimited household incomes make bill savings from an energy efficient hot water system very attractive. Upgrading from an older gas or resistive electric unit to a modern solar hot water heating system or high‑performance heat pump is a logical next step in electrifying the home and locking in long‑term savings.
The local climate helps too. Burnside’s weather station shows mean daily solar exposure of about 15 MJ/m², which is roughly 4.2 kWh/m² of sunlight per day over the year. That strong solar resource supports both solar hot water installation and efficient heat pump hot water installation, especially when paired with rooftop solar. For many homes, hot water is the second‑biggest energy user, so cutting that load delivers meaningful Annual Hot Water Energy Savings.
In the 3030 postcode, demand for efficient hot water has grown strongly. There have been 18,173 efficient hot water installations (heat pump and solar) recorded, with installations ramping up from just a handful in the early 2000s to peak years between 2009 and 2018, when annual installs regularly topped 1,000 systems. While numbers have eased back more recently, there is still steady interest, with hundreds of systems going in each year as Chartwell households chase lower running costs and move away from gas hot water towards all‑electric homes.
For a typical Chartwell home, a 200–315 litre heat pump hot water system or solar hot water tank replacement is common, depending on family size and bathroom count. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular for efficient upgrades, while Rheem solar hot water and Chromagen solar hot water are often chosen where roof orientation is ideal. Many households compare heat pump vs solar hot water, or even solar hot water vs electric hot water, to find the most efficient hot water system for their roof, budget and tariff.
Average annual bill savings will vary, but realistic ranges for Chartwell homes look like:
• Old electric to heat pump hot water system: $400–$900 per year • Gas to heat pump hot water: $300–$700 per year • Gas to solar hot water system: $250–$650 per year • Old electric to modern electric hot water installation with good solar: $250–$600 per year
When it comes to hot water system price and heat pump hot water price, rebates make a real difference. Federal Small‑scale Technology Certificates (STCs) apply to approved heat pump and solar hot water systems, effectively lowering the solar hot water price / cost or heat pump hot water cost at the point of sale. On top of that, Victorian hot water rebate programs can support eligible heat pump hot water installation or solar hot water installation, and there are often incentives for an electric hot water system rebate when replacing inefficient units. Together, these hot water rebate VIC schemes can trim a substantial percentage off upfront costs and shorten payback, especially if you use timers or solar diversion to run your electric hot water vs gas hot water at the cheapest times.
Even if you simply need hot water repair or solar hot water repair rather than a full change‑over, it is worth checking whether a new energy efficient hot water system could pay for itself through lower bills and available hot water rebate VIC support. Many Chartwell homes already running rooftop solar find that pairing it with the best heat pump hot water system they can afford turns excess solar into free showers, making hot water Chartwell households far less exposed to rising tariffs.
If you are wondering which option is the best hot water system Australia can offer for your place – from a compact electric hot water installation to a premium Sanden heat pump or a full rheem solar hot water setup – it pays to get tailored advice. Chartwell’s strong solar exposure, family‑sized homes and growing interest in sustainability mean efficient hot water can seriously cut bills, reduce emissions and future‑proof your property.
