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 Hartley and the 2790 area, 222 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 Hartley's climate delivering an average of 4.5 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 Hartley's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Hartley community is home to 876 couple families with children and 380 one-parent families, meaning a large proportion of households face substantial hot water demand. With 1,766 homes owned with a mortgage and 2,556 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.
Hartley is converting hot water demand to efficient systems faster than many peers, with 3.1% of dwellings already upgraded.
Hot water systems in Hartley
Across Hartley and the wider 2790 area, more households are swapping old gas and power‑hungry electric units for an energy efficient hot water system. With an average household size of around 2.2 people and more than 6,200 occupied dwellings, reliable hot water is non‑negotiable – but so are running costs. Many locals are on tight budgets, with median household income around $1,184 a week, so upgrading to a modern hot water system that slashes energy use simply makes sense.
The climate around Hartley is well suited to efficient technology. Lithgow’s average annual solar exposure is about 16.3 MJ/m² per day, which is roughly 4.5–4.6 kWh/m² of sunshine daily. That is strong support for a solar hot water system or a heat pump hot water system that sips electricity while drawing heat from the air. For older residents – and there are nearly 3,900 people over 65 in the postcode – consistent, affordable hot water is especially important, making the shift away from ageing gas or resistive electric units a logical next step.
In Hartley and nearby towns, most homes are separate houses with three or four bedrooms, so hot water demand can be solid even with smaller families. Hot water can easily account for 20–30% of a home’s energy use, especially where older electric hot water systems run on standard tariffs. That is why more owners are looking at the best hot water system Australia can offer for their situation, comparing heat pump vs solar hot water, and even considering solar hot water vs electric hot water when they already have rooftop solar.
Popular brands in the area include Rheem and Rinnai for both electric and solar hot water heating system options, with Rheem solar hot water and Rinnai solar hot water common on established homes. For top‑end efficiency, many homeowners are turning to Japanese‑designed sanden heat pump units, often rated among the best heat pump hot water system choices on the market. Newer Rheem heat pump hot water models are also appearing on all‑electric homes looking for the most efficient hot water system that still delivers strong pressure on cold Hartley mornings.
When it comes to costs, locals are weighing up hot water system price against long‑term savings. A quality heat pump hot water installation may have a higher upfront heat pump hot water price, but typically uses around 65–75% less electricity than an old electric storage unit. Likewise, a solar hot water installation can cut bills dramatically, especially when paired with PV. Even a modern electric hot water installation, set up with timers to run on solar, can be a very energy efficient hot water system.
To give you a feel for savings, here are typical annual bill reductions many Hartley homes see when they upgrade:
• Old electric to heat pump hot water system: save about $400–$800 per year. • Gas to heat pump hot water: save roughly $300–$700 per year. • Gas to solar hot water system: save around $250–$600 per year. • Old electric to modern electric hot water system using rooftop solar: save about $250–$500 per year.
In the 2790 postcode, there have already been 222 efficient hot water installations, mainly solar hot water and heat pump systems. Installations ramped up sharply around 2009–2011, peaking at 61 systems in 2011, as early rebates and rising power prices pushed interest in electrification. While numbers have been smaller in recent years, steady installations through to 2024 show ongoing demand for hot water repair, solar hot water tank replacement and full hot water installation when older units finally fail.
Homeowners are also comparing solar hot water price with the long‑term savings, and asking whether solar hot water vs electric hot water is better when they have generous north‑facing roof space. Those on gas are increasingly weighing electric hot water vs gas hot water as they plan a future‑proof, all‑electric home.
Hot Water Rebates, Tariffs & Savings NSW
Across Hartley, there is growing interest in replacing old gas or electric hot water with efficient options like a heat pump hot water system, a modern electric hot water system or a solar hot water system. Australian Government Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that cuts the installed solar hot water price or heat pump hot water cost. NSW programs and retailer incentives can also operate as a hot water rebate nsw, further lowering the hot water system price for local homeowners.
For many Hartley households, these discounts can reduce system cost by 20–40%, and typical bill savings of several hundred dollars a year mean payback periods can be surprisingly short – especially if you also have solar and use timers or smart controls to run an electric hot water system when your panels are generating. Some residents also access electric hot water system rebate offers through energy‑efficiency schemes, making it easier to step away from gas for good.
If your current unit is more than 10 years old, running out of hot water, or needing regular hot water repair, it is a good time to look at a heat pump hot water installation, solar hot water repair and upgrade, or a new electric hot water installation. With Hartley’s solid solar resource and strong local interest in sustainability, efficient hot water systems can trim your bills, cut emissions and make your home more comfortable year‑round. To find the best hot water system Australia has for your needs, it pays to speak with experienced local hot water nsw specialists who understand the area, tariffs and rebates. Reach out to trusted Hartley installers for personalised advice, clear pricing and a smooth hot water installation that future‑proofs your home.
