Hot water systems in Elizabeth Hills
Across Elizabeth Hills and the wider 2171 area, more homeowners are rethinking their old gas and electric hot water system and moving to efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an average household size of 3.6 people and more than 10,000 dwellings, hot water demand is high – and so are the savings when you upgrade.
Local families in Elizabeth Hills tend to be younger, with a median age of just 33 and solid household incomes, so comfort and running costs both matter. Many homes are larger four‑bedroom houses, which means long showers, dishwashers and plenty of laundry. Switching from older gas or off‑peak electric to an energy efficient hot water system is a logical next step after solar panels, especially when you factor in the annual hot water energy savings available in a busy family home.
The climate here is ideal for both heat pump and solar hot water heating system options. The nearby Ranieri Place weather station records mean daily solar exposure of about 16.2 MJ/m², which is roughly 4.5 kWh of solar energy per square metre per day across the year. That strong sunlight supports excellent performance for a solar hot water installation and gives a heat pump hot water installation plenty of free ambient energy to work with, making it easier to run your hot water on sunshine instead of gas.
In 2171, efficient hot water upgrades have been steadily rolling out, with 1,081 heat pump and solar hot water installations recorded so far. Installations peaked between 2009 and 2013, when annual numbers regularly topped 100 systems per year, showing strong local interest in electrification and lower running costs. While recent years show fewer recorded installs, the trend is shifting again as more people compare heat pump vs solar hot water and look for the most efficient hot water system to match their rooftop solar.
For a typical Elizabeth Hills household, hot water can make up a quarter or more of total energy use, so the right hot water installation can noticeably reduce bills. Upgrades might look like this:
• Old electric to heat pump: save around $400–$800 per year on bills. • Gas to heat pump: save roughly $300–$600 per year, depending on gas tariffs. • Gas to solar hot water: save about $250–$550 per year. • Old electric to modern electric with solar: save $250–$500 per year using daytime solar.
Brands like Rheem heat pump hot water and Rheem solar hot water are popular in family homes, while Rinnai solar hot water and Chromagen solar hot water systems are also common choices for a reliable solar hot water tank replacement. For those chasing the best heat pump hot water system, premium units like the Sanden heat pump are often paired with solar to create a truly energy efficient hot water system that runs mostly on free rooftop generation.
When you are comparing solar hot water vs electric hot water, or electric hot water vs gas hot water, it is important to look beyond the hot water system price / cost on day one. A heat pump hot water price / cost can seem higher upfront, but running costs are far lower than a basic electric unit. Similarly, a quality solar hot water price / cost pays back over time through cheaper energy and less exposure to rising gas prices.

For Elizabeth Hills households, the financial case for upgrading is boosted by hot water rebate nsw programs. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water system and heat pump hot water system installations, effectively cutting the sticker price. On top of that, state‑based schemes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when you replace an old, inefficient unit. These discounts can reduce system cost by a substantial percentage and trim payback periods down to just a few years, especially when you run your hot water during the day on solar or use timers and smart controls.
With rising energy costs and a clear local interest in sustainability, now is a smart time for Elizabeth Hills homeowners to check whether their current unit is close to the end of its life. If your system is older, noisy, or struggling to keep up with demand, it may be worth planning a hot water repair or a full upgrade before it fails.
