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 Robertson and the 2577 area, 506 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 Robertson's climate delivering an average of 4.3 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 Robertson
Across Robertson and the wider 2577 area, more households are rethinking their old gas and electric hot water system and moving to 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 about 2.4 people and more than 6,300 dwellings in the postcode, reliable hot water is a daily essential – but so is keeping power bills under control.
Energy costs have been rising, and many Robertson homeowners are on fixed incomes, with a median household income around $1,667 a week and a relatively older population. That makes the annual hot water energy savings from upgrading especially attractive. Robertson’s mean daily solar exposure sits at about 15.3 MJ/m² – roughly 4.25 kWh per square metre per day – which is more than enough sunshine to support a solar hot water heating system or boost the efficiency of a heat pump hot water system, even in the cooler Highlands climate.
Most homes in 2577 are separate houses, many owned outright or with a mortgage, which makes hot water installation upgrades easier to plan. Swapping out an ageing gas unit or a power‑hungry electric storage tank for an energy efficient hot water system is a logical next step for families wanting lower running costs, fewer breakdowns and a smaller carbon footprint. Modern systems like Rheem solar hot water, Rinnai solar hot water, Rheem heat pump hot water and premium options such as Sanden heat pump units are all popular choices for those chasing the best hot water system Australia can offer for long‑term savings.
In Robertson, a typical family home’s hot water use is a sizeable chunk of total energy consumption, especially for three‑ and four‑bedroom homes. That is why the shift to efficient systems is gathering pace. Average annual bill savings can look like:
• Old electric to heat pump hot water installation: around $400–$800 per year • Gas to heat pump: roughly $300–$600 per year • Gas to solar hot water installation: about $250–$550 per year • Old electric to modern electric hot water installation with rooftop solar: around $250–$500 per year
Local installers are seeing more interest in brands such as Rheem, Rinnai and Sanden for the best heat pump hot water system options, as well as Chromagen solar hot water for roof‑mounted collectors. These systems are designed to work well with existing solar PV, helping make solar hot water vs electric hot water an easy decision for many households.
Robertson already has 506 efficient hot water systems installed, combining heat pump and solar hot water installations. There was a big surge around 2009–2011, when installations peaked at over 100 systems in a single year, and steady activity since then. This trend shows growing local interest in electrification, lower running costs and using the area’s decent solar resource for hot water NSW homes. As systems age, more residents are now looking at hot water repair versus full replacement, including solar hot water tank replacement, and often deciding that a new system is the most efficient hot water system choice in the long run.
Hot Water Rebates, Tariffs & Savings
Right across Robertson, more people are weighing up heat pump vs solar hot water, or even solar hot water vs electric hot water, when their old unit fails. Australian Government incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water system upgrades, effectively acting like an upfront discount. On top of that, NSW hot water rebate programs can support heat pump hot water rebate offers and solar hot water rebate options for qualifying homes, while some schemes also provide an electric hot water system rebate when moving away from gas.
For many Robertson households, these hot water rebate NSW incentives can cut the effective heat pump hot water price or solar hot water price by a substantial percentage, turning a big upfront hot water system price into a much more manageable investment. With typical savings of hundreds of dollars a year on bills, the payback period for a quality energy efficient hot water system can be shortened significantly, especially if you use timers or solar diversion to run an electric hot water system when your PV is generating.
If your current unit is old, noisy or unreliable, now is a smart time to see whether a hot water upgrade makes sense. Whether you are comparing electric hot water vs gas hot water, looking at rheem solar hot water or chromagen solar hot water, or wanting to know the true heat pump hot water cost, experienced local installers can walk you through the options. Robertson’s strong interest in sustainability and efficient homes means there are proven solutions for cutting bills, reducing emissions and future‑proofing your property.
