The 3612 postcode, covering Whroo, Moora, Rushworth, Wanalta, Waranga and Waranga Shores and surrounding areas, is home to around 912 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 Whroo and the 3612 area, 116 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 Whroo's climate delivering an average of 4.8 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 Whroo
Across Whroo and the 3612 area, more homeowners are swapping old gas and tired electric units for an energy efficient hot water system that keeps bills down and comfort up. With an average household size of around 2.1 people and a big share of homes owned outright or with a mortgage, many locals are looking at smart upgrades that add value without blowing the budget. Hot water can be one of the biggest energy users in the home, so upgrading your hot water system is often the easiest way to lock in long‑term savings.
Whroo is well suited to efficient hot water. At nearby Goulburn Weir, the average annual solar exposure is about 17.1 MJ/m² per day, which is roughly 4.75 kWh/m² of sun each day. That strong sunlight helps a solar hot water system or heat pump hot water system work at its best, especially when paired with rooftop solar. For many households on modest median incomes, trimming hundreds of dollars a year from power bills with a modern solar hot water heating system or high‑efficiency electric hot water system makes a lot of sense. Moving away from older gas and off‑peak electric hot water towards the most efficient hot water system you can afford is a practical step towards an all‑electric, lower‑carbon home.
Around Whroo’s separate houses and lifestyle properties, hot water demand is steady rather than huge, but it still adds up. Many homes have three bedrooms, so a family or downsizing couple will typically look at a 250–315 litre tank for an electric hot water installation or heat pump hot water installation, or a similar‑sized solar hot water tank replacement. Local installers regularly work with leading brands such as Rheem, Rinnai and Sanden, with options ranging from Rheem solar hot water and Rheem heat pump hot water, through to Rinnai solar hot water and premium Sanden heat pump units. These sit alongside other quality systems that regularly appear on “best hot water system Australia” and “best heat pump hot water system” shortlists.
To give you a feel for savings, here are typical annual bill reductions when you upgrade, depending on tariffs and usage:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water: $300–$700 per year • Gas to solar hot water system: $250–$600 per year • Old electric to modern electric hot water with solar: $250–$500 per year
In Whroo, there have already been 116 efficient hot water installations recorded, covering both heat pump and solar hot water installation projects. Installations jumped sharply around 2009 and 2010, with 26 and 20 systems installed in those years alone, then continued steadily through the 2010s. Recent years have seen renewed interest, with systems going in during 2022, 2023 and 2024 as more locals focus on electrification, heat pump vs solar hot water comparisons, and finding an energy efficient hot water system that suits their property.
For Whroo households, hot water vic rebates and tariffs are a big part of the picture. Many residents are keen to replace ageing gas units or off‑peak cylinders with a new heat pump hot water system, solar hot water system or efficient electric hot water system, especially when a solar hot water rebate or heat pump hot water rebate is available. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively reducing the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of this, state‑based hot water rebate vic programs can further cut the upfront hot water system price / cost, and some efficient electric hot water system rebate offers support going all‑electric.
When you combine these incentives with good tariffs, typical savings from an efficient hot water upgrade can easily reach hundreds of dollars per year, with payback periods shortened significantly. Many Whroo homes already have solar, so using timers or solar‑diversion controls to run a solar hot water vs electric hot water setup in the middle of the day can squeeze even more value from your panels. For those comparing electric hot water vs gas hot water, the numbers increasingly favour modern, efficient electric and heat pump units, especially once you factor in rising gas prices and the option of solar hot water repair or heat pump servicing instead of full replacement down the track.
If your system is more than 10 years old, running out of hot water or needing frequent hot water repair, it is worth checking whether a hot water upgrade could work for your Whroo home. Whether you are weighing up heat pump vs solar hot water, looking at chromagen solar hot water alternatives, or simply want reliable hot water vic performance with lower bills, experienced local installers can help you compare options, rebates and running costs.
