The 2015 postcode, covering Alexandria, Beaconsfield and Eveleigh and surrounding areas, is home to around 5,861 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 Alexandria and the 2015 area, 87 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 Alexandria's climate delivering an average of 4.6 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.

Hot water systems in Alexandria
In Alexandria, more households and businesses are rethinking their old gas and electric 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 young, busy population (median age around 34) and an average household size of 2.1 people, reliable, low‑running‑cost hot water is a big deal for both renters and owners. When you are paying a median rent of about $558 a week or a hefty mortgage, cutting energy bills with a more efficient hot water installation just makes sense.
Alexandria’s climate is ideal for efficient hot water. The local weather station records an average annual solar exposure of about 16.5 MJ/m² per day – roughly 4.6 kWh/m² of sunshine – which is plenty to support a high‑performing solar hot water heating system and boost the efficiency of a heat pump hot water system. With more than 5,200 occupied dwellings, from terraces to modern apartments, even modest Annual Hot Water Energy Savings per home add up to a serious community win when people upgrade from older gas or resistive electric units.
In 2015 Alexandria had over 5,000 dwellings, many of them newer apartments with good insulation but limited space, so compact heat pump hot water installation is increasingly popular. A lot of homes are already electrifying, pairing rooftop solar with the most efficient hot water system they can fit. For many, the choice comes down to heat pump vs solar hot water, or solar hot water vs electric hot water with smart timers.
Typical bill savings from a hot water upgrade in Alexandria look like this:
• Old electric to heat pump hot water system: save around $350–$700 a year • Gas to heat pump hot water: save roughly $250–$600 a year • Gas to solar hot water system: save about $250–$550 a year • Old electric to modern electric hot water installation with rooftop solar: save around $200–$500 a year
Brands like Rheem heat pump hot water, Rinnai solar hot water, Sanden heat pump and Chromagen solar hot water are all common choices locally, with options to suit small apartments through to larger family homes. Many locals ask about the best hot water system Australia has to offer; in practice, the best heat pump hot water system or solar option for you depends on roof space, tariffs, and whether you already have solar PV.
Efficient hot water is not new to the suburb. In postcode 2015 there have been 87 efficient hot water systems installed so far, including both heat pump and solar hot water installation projects. Installations climbed steadily from the early 2000s, peaking around 2010–2012 when annual installs hit double digits, and have continued at a steady trickle right through to 2025. That ongoing pattern shows growing interest in electrification, lower running costs and energy efficient hot water system choices across Alexandria, NSW. As older systems reach the end of their life, more households are choosing solar hot water tank replacement or a new heat pump hot water installation instead of like‑for‑like gas.
Hot Water Rebates, Tariffs & Savings
Across Alexandria there is strong interest in replacing old gas or electric hot water with efficient options, whether that is a sanden heat pump, a rheem solar hot water system, rinnai solar hot water, or a modern electric hot water system with timer control. Federal incentives like Small‑scale Technology Certificates (STCs) can reduce the solar hot water price / cost and heat pump hot water price / cost at the point of sale, while NSW hot water rebate programs and occasional electric hot water system rebate offers help bring down upfront costs even further. For many Alexandria homeowners, these discounts can effectively cut the hot water system price / cost by 20–40%, which shortens payback times to just a few years. Combine that with rooftop solar, a smart tariff, and perhaps a solar‑diverter or timer, and your solar hot water price / cost or electric hot water system running on solar can often be paid back much faster, especially when you are avoiding rising gas prices. When you compare electric hot water vs gas hot water, or heat pump vs solar hot water, the numbers usually favour going all‑electric with an energy efficient hot water system, especially under NSW hot water rebate schemes and the broader hot water rebate nsw framework.
If you are in Alexandria and your current unit is ageing, noisy or expensive to run, now is a smart time to look at a heat pump hot water system, solar hot water vs electric hot water with solar, or even a high‑efficiency replacement electric unit.
