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 Roughit and the 2330 area, 1,261 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 Roughit's climate delivering an average of 4.7 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.

Community Hot Water Statistics - Roughit, 2330
Hot Water Demographics - Roughit
Based on the Australian Bureau of Statistics 2021 Census (ABS), Roughit has around 8,315 private dwellings, home to approximately 20,063 people. With an average household size of 2.6 people, and around 50 litres of hot water used per person each day in Australia, Roughit households use approximately 130 litres of hot water daily, equating to a massive 1.1 million litres of hot water used across the suburb every single day.
Other census insights reinforce Roughit's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Roughit community is home to 1,837 couple families with children and 516 one-parent families, meaning a large proportion of households face substantial hot water demand. With 3,001 homes owned with a mortgage and 2,355 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.
Roughit is converting hot water demand to efficient systems faster than many peers, with 15.2% of dwellings already upgraded.
Hot water systems in Roughit
Across Roughit and the wider 2330 area, more homeowners are swapping old gas and ageing electric units for modern, energy efficient hot water systems. With most of the 7,600 dwellings here being separate houses and an average household size of 2.6 people, hot water demand is steady – and so are the running costs if you stick with an outdated hot water system. Rising energy prices and a strong local focus on family budgets (median household income around $1,952 a week and plenty of homes with mortgages) make upgrading to an efficient heat pump hot water system, solar hot water system or modern electric hot water system a logical next step.
Roughit is well suited to efficient hot water technology. The Singleton station records an average annual solar exposure of about 17.1 MJ/m² per day – roughly 4.75 kWh of sunshine per square metre, per day. That strong solar resource means a solar hot water heating system can do much of the work for free, and a well‑sized heat pump hot water system can run cheaply on daytime solar power. For many homes, shifting from old gas or resistive electric to an energy efficient hot water system can save hundreds of dollars every year in hot water energy use alone.
In the 2330 postcode, family homes with three or four bedrooms are common, so showers, baths and laundry loads quickly add up. That is why more locals are comparing heat pump vs solar hot water and even solar hot water vs electric hot water to find the most efficient hot water system for their household. Brands like Rheem heat pump hot water, Sanden heat pump systems and rooftop options such as Rheem solar hot water or Chromagen solar hot water are all popular choices, alongside Rinnai solar hot water for those wanting a proven solar hot water installation. For many, these are among the best hot water system Australia has to offer in real‑world conditions, not just on paper.
Typical annual bill savings in Roughit look like this:
• Old electric to heat pump hot water installation: $350–$700 per year • Gas to heat pump hot water system: $250–$600 per year • Gas to solar hot water installation: $200–$550 per year • Old electric to modern electric hot water installation with rooftop solar: $200–$450 per year
Local data shows this shift is already under way. There have been 1,261 efficient hot water installations – mainly heat pump and solar hot water – recorded in the 2330 area. Install numbers grew from just a handful in the early 2000s to peaks around 2009–2011, when over 580 systems went in across those three years. While yearly volumes have eased since, steady installations through to 2025 show ongoing interest in electrification, solar hot water tank replacement and lower running costs for homes in Roughit NSW. Many of these households are now enjoying lower hot water system price impacts on their bills, along with quieter, more reliable systems and less need for urgent hot water repair.
Hot Water Rebates, Tariffs & Savings
For Roughit homeowners, hot water nsw rebates and tariffs are a big part of the decision. Federal incentives like Small‑scale Technology Certificates (STCs) can cut the upfront solar hot water price / cost or heat pump hot water price / cost, while state‑based heat pump hot water rebate and solar hot water rebate programs in NSW further reduce the hot water system price / cost at installation. There are also electric hot water system rebate options in some programs, helping households move from electric hot water vs gas hot water towards more efficient, all‑electric homes.
When you stack these hot water rebate nsw offers together, it is common for discounts to cover a substantial portion of the system and installation. That shortens payback periods, especially if you run your heat pump on a solar‑friendly tariff, use timers, or add solar‑diversion so excess rooftop solar feeds your hot water. Many Roughit households are seeing payback in just a few years, then ongoing savings for the life of the system.
If your current unit is more than 10 years old, noisy, or needing regular hot water repair, it is a good time to check whether a heat pump hot water system, solar hot water system or efficient electric hot water system is right for your place.
