Hot Water Systems in Bexley
The 2207 postcode, covering Bexley, Bardwell Park, Bardwell Valley, Bexley North and Bexley South and surrounding areas, is home to around 10,025 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 Bexley and the 2207 area, 265 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 Bexley'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.

Community Hot Water Statistics - Bexley, 2207
Hot Water Demographics - Bexley
Based on the Australian Bureau of Statistics 2021 Census (ABS), Bexley has around 10,025 private dwellings, home to approximately 26,580 people. With an average household size of 2.8 people, and around 50 litres of hot water used per person each day in Australia, Bexley households use approximately 140 litres of hot water daily, equating to a massive 1.4 million litres of hot water used across the suburb every single day.
Other census insights reinforce Bexley's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Bexley community is home to 2,358 couple families with children and 442 one-parent families, meaning a large proportion of households face substantial hot water demand. With 3,246 homes owned with a mortgage and 3,496 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.
Bexley is converting hot water demand to efficient systems faster than many peers, with 2.6% of dwellings already upgraded.
Hot water systems in Bexley
Across Bexley, more households are switching to energy efficient hot water systems to keep bills under control and move away from ageing gas units. With an average household size of about 2.8 people and more than 9,300 occupied dwellings, a reliable hot water system is essential, whether you are in a classic separate house or one of the many townhouses and apartments around 2207. Rising energy costs and solid median household incomes mean many Bexley owners are now seeing a hot water upgrade as a smart, long term investment rather than just a grudge purchase.
Bexley’s climate is ideal for efficient hot water. Local solar data from Bexley Bowling Club shows mean daily solar exposure of about 16.4 MJ/m², or roughly 4.5–4.6 kWh/m² per day over the year. That level of sunlight supports both a solar hot water system and a modern heat pump hot water system, especially when paired with rooftop solar. For many families and older couples in the suburb, replacing an old gas or electric hot water system with a heat pump or solar hot water heating system can deliver sizeable annual hot water energy savings while cutting emissions.
With thousands of three and four bedroom homes, hot water demand in Bexley is steady year round. Many properties still run gas or older resistive electric units, which are some of the least efficient options. Upgrading to an energy efficient hot water system, such as a Sanden heat pump or Rheem heat pump hot water unit, or choosing a quality Rheem solar hot water or Rinnai solar hot water system, can dramatically reduce running costs. For homes with good roof space, a solar hot water installation, sometimes combined with a solar hot water tank replacement, can be one of the most efficient ways to heat water. Others prefer a heat pump hot water installation that works like a reverse cycle air conditioner for your tank, using far less electricity than a traditional electric hot water system.
In Bexley 2207 there have already been 265 efficient hot water installations, covering both heat pump and solar hot water. Installations surged between 2008 and 2011, with a peak of 56 systems in 2009 and strong numbers through 2010 and 2011, then steady upgrades each year since. That trend reflects growing local interest in electrification, lower running costs and moving towards the most efficient hot water system options available. Many newer installs are paired with rooftop solar, making solar hot water vs electric hot water an easy decision when households see the bill savings.
Typical savings in Bexley will vary with household size and tariffs, but the pattern is clear. Moving from an old electric hot water system to a quality heat pump hot water system can cut heating energy by around two thirds. Swapping gas to heat pump or gas to solar hot water also trims usage significantly. Even a modern electric hot water installation, when paired with rooftop solar and a timer, can outperform older units. To give a sense of what is possible, average annual bill savings might look like:
• Old electric to heat pump: $400–$800 per year • Gas to heat pump: $250–$600 per year • Gas to solar hot water: $250–$600 per year • Old electric to modern electric with solar: $200–$500 per year
For many homes, the best hot water system Australia offers will be the one that balances upfront hot water system price, roof space, and running costs. Some Bexley households want the best heat pump hot water system they can afford, often looking at brands like Sanden or other premium units. Others prefer a proven solar hot water system from brands such as Rheem or Rinnai, or a chromagen solar hot water style setup, especially where there is strong north facing roof and plenty of sunshine. When comparing heat pump vs solar hot water, it often comes down to roof layout, shading, and whether you already have or plan to add solar PV.
For businesses and unit blocks, a well sized heat pump hot water system or central solar hot water heating system can also be a smart way to reduce common area energy use. Commercial owners often compare electric hot water vs gas hot water carefully, and increasingly choose efficient electric options to align with sustainability goals and future proof against gas price rises.
Hot water rebates, tariffs and savings are a big part of the story for hot water NSW upgrades. Federal incentives such as Small scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively lowering the solar hot water price or heat pump hot water price at the point of sale. On top of that, state based programs can offer a heat pump hot water rebate, solar hot water rebate, or electric hot water system rebate that further reduces the hot water system cost for Bexley homeowners. These discounts can bring the net solar hot water price / cost or heat pump hot water price / cost down by a substantial percentage, especially when combined with competitive supply and installation quotes.
When you add bill savings of a few hundred dollars per year, many Bexley households see payback periods shorten considerably. Using timers, smart controls or solar diversion to run an electric hot water system or heat pump during solar hours can improve savings again, and helps ensure your hot water NSW setup is working hard for you. For anyone exploring solar hot water vs electric hot water, or planning a solar hot water repair or hot water repair on an older unit, it is often worth pricing a full upgrade instead, particularly when hot water rebate NSW options are available.
If your current unit is more than 10 years old, running out of hot water, or costing a fortune to run, it may be time to look at a hot water installation upgrade in Bexley. Whether you are considering a solar hot water repair, a solar hot water tank replacement, a new electric hot water installation or a complete heat pump hot water installation, working with experienced hot water installers who specialise in efficient systems is crucial. With Bexley’s strong solar exposure and growing interest in sustainability, a modern energy efficient hot water system can help you cut bills, reduce emissions and future proof your home.
