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 Coreen and the 2646 area, 104 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 Coreen's climate delivering an average of 4.9 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 - Coreen, 2646
Hot Water Demographics - Coreen
Based on the Australian Bureau of Statistics 2021 Census (ABS), Coreen has around 3,269 private dwellings, home to approximately 6,121 people. With an average household size of 2.2 people, and around 50 litres of hot water used per person each day in Australia, Coreen households use approximately 110 litres of hot water daily, equating to a massive 0.4 million litres of hot water used across the suburb every single day.
Other census insights reinforce Coreen's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Coreen community is home to 400 couple families with children and 132 one-parent families, meaning a large proportion of households face substantial hot water demand. With 743 homes owned with a mortgage and 1,323 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.
Coreen is converting hot water demand to efficient systems faster than many peers, with 3.2% of dwellings already upgraded.
Hot water systems in Coreen
Across Coreen and the wider 2646 area, more households are rethinking their old hot water system and moving to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With a median household size of around 2.2 people and more than 2,800 dwellings, many Coreen homes are older separate houses that still run on ageing gas or off-peak electric hot water. Rising energy costs and a median household income of about $1,165 a week mean every dollar on the power bill counts, so upgrading to an energy efficient hot water system is a logical next step.
Coreen’s climate is ideal for efficient hot water. The local weather station at Daysdale records an average annual solar exposure of about 17.7 MJ/m² per day, which is roughly 4.9 kWh/m² of sunshine daily. That strong sunlight helps a solar hot water heating system and a modern heat pump hot water system perform really well, especially when paired with rooftop solar. For many families and retirees (over 2,000 locals are 65+), shifting from gas or resistive electric to the most efficient hot water system they can afford can lock in solid Annual Hot Water Energy Savings for years to come.
In the 2646 postcode, most homes have two to four bedrooms, so hot water demand is steady rather than extreme, making systems in the 250–315 litre range popular for both solar hot water installation and heat pump hot water installation. A growing number of homes already using solar power are now looking at heat pump vs solar hot water, or even solar hot water vs electric hot water with a smart timer, to get the best value from their panels. Brands like Rheem and Rinnai are common choices for a reliable hot water installation, with options such as Rheem solar hot water, Rheem heat pump hot water and Rinnai solar hot water. Premium systems like the Sanden heat pump are also appearing where households want the best heat pump hot water system and very low running costs.
Typical bill savings in Coreen for a well-chosen upgrade can look like:
• Old electric to heat pump: $350–$700 per year • Gas to heat pump: $250–$600 per year • Gas to solar hot water: $200–$550 per year • Old electric to modern electric hot water with solar: $200–$450 per year
These ranges will vary with usage, tariffs and how much solar you have, but they are realistic for many local homes. When comparing heat pump hot water price / cost or solar hot water price / cost to a basic electric hot water system price / cost, it is worth factoring in these savings and the longer-term protection from bill rises.
Coreen has already seen 104 efficient hot water systems installed, combining heat pump and solar hot water installation jobs. Installations really picked up around 2009–2011, when 42 systems went in over just three years, and there was another bump in 2014. More recently, there has been steady interest, with new systems going in most years through to 2025. This pattern shows a clear local shift towards electrification, lower running costs and cutting reliance on bottled or mains gas hot water.
For hot water NSW homeowners, rebates and tariffs are a big part of the story. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively lowering the upfront solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, state-based schemes can provide a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some programs, all aimed at making an energy efficient hot water system more affordable. In practical terms for Coreen households, these discounts can shave a substantial percentage off the installed cost and shorten the payback period to just a few years, especially if you run your system on a solar-friendly tariff or use timers and solar diversion to heat water when your panels are producing.
Whether you are comparing electric hot water vs gas hot water, weighing up heat pump vs solar hot water, or just trying to find the best hot water system Australia for a typical Coreen home, it pays to think beyond the sticker price. A well-sized Rheem solar hot water or Chromagen solar hot water unit, a quality Sanden heat pump, or a modern, tariff-optimised electric hot water installation can all deliver reliable hot water repair support, lower running costs and fewer surprises on your bill. If your existing unit is leaking or you need a solar hot water tank replacement or solar hot water repair, that is often the perfect moment to upgrade rather than simply replace like-for-like.
If you live in Coreen and your current system is old, noisy or expensive to run, this is a great time to check whether your place is ready for a hot water upgrade. With strong local sunshine, growing interest in sustainability and generous hot water rebate NSW programs, efficient options like heat pump hot water installation, solar hot water installation and smarter electric hot water installation can cut bills, reduce emissions and future-proof your home.
