Hot Water Systems in Penrose
The 2579 postcode, covering Penrose, Big Hill, Brayton, Exeter, Marulan, Marulan South, Tallong and Wingello and surrounding areas, is home to around 2,070 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 Penrose and the 2579 area, 170 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 Penrose's climate delivering an average of 4.4 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 - Penrose, 2579
Hot Water Demographics - Penrose
Based on the Australian Bureau of Statistics 2021 Census (ABS), Penrose has around 2,070 private dwellings, home to approximately 4,314 people. With an average household size of 2.5 people, and around 50 litres of hot water used per person each day in Australia, Penrose households use approximately 125 litres of hot water daily, equating to a massive 0.3 million litres of hot water used across the suburb every single day.
Other census insights reinforce Penrose's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Penrose community is home to 360 couple families with children and 68 one-parent families, meaning a large proportion of households face substantial hot water demand. With 634 homes owned with a mortgage and 743 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.
Penrose is converting hot water demand to efficient systems faster than many peers, with 8.2% of dwellings already upgraded.
Hot water systems in Penrose
Across Penrose and the wider 2579 area, more households are swapping old gas and electric units for an energy efficient hot water system that actually suits modern living. With most homes here being separate houses and an average household size of around 2.5 people, hot water demand is steady all year, and rising energy costs mean every shower and load of washing adds up. Many families are on a median household income of about $1,589 a week, so upgrading to a more efficient hot water system is a practical way to free up the budget.
Penrose gets solid sunlight for the Southern Highlands, with average annual solar exposure of about 15.9 MJ/m² a day – roughly 4.4 kWh/m². That is more than enough to support a quality solar hot water system or heat pump hot water system, especially when paired with rooftop solar. For homeowners looking at the annual hot water energy savings possible by moving away from older gas or resistive electric units, the numbers can be compelling over the life of the system.
In a postcode with more than 1,600 occupied dwellings and a high share of homes owned outright or with a mortgage, long term running costs matter as much as the upfront hot water system price. Many locals are weighing up heat pump vs solar hot water, or even a modern electric hot water system that works hand in hand with solar PV. A well sized solar hot water heating system or heat pump hot water installation can become one of the biggest contributors to making an all electric home viable in Penrose NSW.
For a typical 3–4 bedroom home in Penrose, hot water can account for a quarter or more of total electricity use. That is why heat pump hot water, solar hot water vs electric hot water, and even efficient electric hot water vs gas hot water are such hot topics locally. Brands like Rheem heat pump hot water, Sanden heat pump, Rinnai solar hot water and Thermann are common choices for anyone chasing the most efficient hot water system without sacrificing reliability. Many households still prefer a straightforward electric hot water installation, while others opt for a rheem solar hot water or chromagen solar hot water style setup with roof collectors and a solar hot water tank replacement when the old cylinder finally gives up.
Average yearly bill savings in Penrose for typical upgrades can look like:
• Old electric to heat pump hot water system: $400–$800 per year • Gas storage to heat pump hot water: $300–$700 per year • Gas storage to solar hot water system: $250–$600 per year • Old electric to modern electric hot water system with solar PV: $300–$700 per year (with good solar self use)
Local data shows 170 efficient hot water systems have already been installed in the 2579 postcode, including both heat pump and solar hot water installation projects. There was a strong surge around 2009–2010, when 55 systems went in over just two years, and interest has picked up again with new units going in during 2024 and 2025. That trend reflects growing awareness of electrification, lower running costs and the appeal of an energy efficient hot water system that keeps bills down for decades.
Even if you are only just starting to think about hot water in Penrose NSW, there is a clear shift from old gas and ageing electric units towards options like heat pump hot water, solar hot water and high efficiency electric. Federal incentives such as Small scale Technology Certificates (STCs) can reduce the effective solar hot water price or heat pump hot water price at the point of sale, while NSW hot water rebate programs often support low emission technologies. Together, these hot water rebate NSW schemes and the electric hot water system rebate options available through some programs can cut the upfront hot water system cost by a substantial margin, shortening payback times. When you add smart controls, timers or solar diversion, your solar hot water price / cost or heat pump hot water cost can be paid back even faster through hundreds of dollars a year in savings.
If your Penrose home still runs on an old gas or electric unit, now is a good time to see whether a heat pump hot water installation, solar hot water repair and upgrade, or new electric hot water installation could work for you.
