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 Middlesex and the 7306 area, 92 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 Middlesex's climate delivering an average of 3.9 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 - Middlesex, 7306
Hot Water Demographics - Middlesex
Based on the Australian Bureau of Statistics 2021 Census (ABS), Middlesex has around 1,757 private dwellings, home to approximately 3,683 people. With an average household size of 2.3 people, and around 50 litres of hot water used per person each day in Australia, Middlesex households use approximately 115 litres of hot water daily, equating to a massive 0.2 million litres of hot water used across the suburb every single day.
Other census insights reinforce Middlesex's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Middlesex community is home to 250 couple families with children and 60 one-parent families, meaning a large proportion of households face substantial hot water demand. With 560 homes owned with a mortgage and 775 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.
Middlesex is converting hot water demand to efficient systems faster than many peers, with 5.2% of dwellings already upgraded.
Hot water systems in Middlesex
Across Middlesex and the 7306 area, more locals are switching from old gas and electric units to modern, energy efficient hot water systems. With most of the 1,590 dwellings being separate houses and an average household size of 2.3 people, a reliable hot water system is essential, but so is keeping running costs down. Power prices bite harder when you are on a median household income of around $1,182 a week, so upgrading to an efficient heat pump hot water system, solar hot water system or well‑sized electric hot water system can make a real dent in your bills.
Middlesex is actually well suited to efficient hot water technology. The local climate data from nearby Lorinna shows mean daily solar exposure of about 14 MJ/m², which is roughly 3.9 kWh per square metre per day over the year. That steady sunlight supports both a solar hot water heating system and high‑efficiency heat pump hot water, especially when paired with rooftop solar. With many homes owned outright or with a mortgage, and a slightly older population (median age 50, with over 1,000 residents aged 65+ in the postcode), there is strong interest in cutting energy bills and simplifying maintenance by moving to the most efficient hot water system you can reasonably afford.
In a typical Middlesex home, hot water can account for a big slice of electricity use, especially where older resistive cylinders or gas storage units are still running. Swapping those out for an energy efficient hot water system is one of the quickest ways to reduce usage without changing your lifestyle. Local installers regularly work with trusted brands like Rheem, Rinnai and Sanden, whether that is a rheem solar hot water setup, rheem heat pump hot water, rinnai solar hot water system or a premium sanden heat pump for households chasing the best heat pump hot water system on the market. Chromagen solar hot water and other leading brands are also options where roof space and orientation suit a full solar hot water installation.
When you look at heat pump vs solar hot water, both can work well in hot water TAS conditions. A solar hot water system or solar hot water heating system uses roof collectors and a solar hot water tank replacement or new tank, while a heat pump hot water installation works like a reverse‑cycle air conditioner for your cylinder. For homes already running rooftop solar, solar hot water vs electric hot water often comes down to whether you prefer a dedicated solar hot water installation or a smart heat pump on a timer soaking up excess solar. Either way, a modern electric hot water installation can be extremely efficient when controlled well, and there are options for an electric hot water system rebate as part of moving away from gas.
To give you a feel for savings, here are some realistic annual bill reductions many Middlesex households see when they upgrade:
• Old electric to quality heat pump hot water system: $400–$800 per year • Gas storage to heat pump hot water system: $300–$600 per year • Gas storage to solar hot water system: $250–$550 per year • Old electric to modern electric hot water system run on solar: $250–$500 per year
Over the years, efficient hot water has quietly grown in the area. There have been 92 efficient hot water systems installed in postcode 7306, including both heat pump and solar hot water installations. Installations really took off around 2010–2012, with a peak of 27 systems in 2011, and there has been steady interest since, with new systems going in as recently as 2022, 2023 and 2025. That pattern shows more Middlesex households are looking seriously at electrification, lower running costs and replacing ageing gas or electric units before they fail, often combining hot water installation with rooftop solar.
Hot Water Rebates, Tariffs & Savings
With rising energy prices, hot water TAS homeowners are increasingly keen to replace old gas or electric units with a heat pump hot water system, solar hot water system or efficient electric hot water system. Federal incentives like Small‑scale Technology Certificates (STCs) apply to many heat pump and solar hot water systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate. On top of that, state‑based hot water rebate TAS programs can further cut the heat pump hot water price or solar hot water price, reducing the overall hot water system price or cost by a substantial percentage in some cases.
For many Middlesex households, that can mean hundreds of dollars off the upfront heat pump hot water cost or solar hot water price, and ongoing bill savings of hundreds per year. When you combine rebates with good tariffs, timers or solar diversion, the payback period on an upgrade can be shortened dramatically. Using a timer to run a heat pump in the middle of the day on solar, or prioritising hot water when your panels are generating, turns an efficient hot water system into a real bill‑buster.
If you are in Middlesex and your existing unit is older, noisy or struggling, now is a smart time to look at options like rheem solar hot water, rinnai solar hot water, a sanden heat pump or other systems considered among the best hot water system Australia has to offer. Whether you are weighing up solar hot water vs electric hot water, thinking about solar hot water repair or solar hot water tank replacement, or simply need fast hot water repair on a leaking cylinder, working with experienced local specialists matters.
Before your current system calls it quits, it is worth checking whether your home is ready for a hot water upgrade. A quick chat with trusted local hot water installers can help you compare electric hot water vs gas hot water, understand any hot water rebate TAS options available, and choose the most efficient hot water system for your household size and budget. With the right heat pump hot water installation, solar hot water repair or electric hot water installation, you can reduce bills, cut emissions and future‑proof your Middlesex home—reach out to our local experts for personalised advice and a clear plan for your next hot water system.
