Across Bunnaloo and the wider 2731 area, more households are rethinking their old gas and electric hot water system and switching to efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With an average household size of around 2.4 people and more than 2,800 occupied dwellings, reliable hot water is essential – but so is keeping running costs under control as power prices rise.
Bunnaloo enjoys strong sunshine, with mean daily solar exposure of about 17.8 MJ/m² – roughly 5 kWh/m² per day – which is ideal for both a solar hot water heating system and high‑efficiency heat pump hot water. Many homes are owner‑occupied (over 2,000 dwellings are owned outright or with a mortgage), so upgrading from older gas or resistive electric units to an energy efficient hot water system is a logical next step. For a typical family here, annual hot water energy savings from a smart upgrade can easily reach hundreds of dollars a year, especially when paired with rooftop solar.
In the 2731 postcode, most homes are separate houses with three or four bedrooms, so hot water demand can be significant – particularly for families and multi‑generation households. Hot water can account for around a quarter of total household energy use, so choosing the most efficient hot water system has a big impact on bills. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, offering everything from rheem solar hot water and rheem heat pump hot water to rinnai solar hot water and premium sanden heat pump options for those chasing the best heat pump hot water system and the most efficient hot water system on the market.
Average annual bill savings in Bunnaloo for typical upgrades can look like this:
• Old electric to heat pump hot water installation: save around $400–$800 per year. • Gas to heat pump vs solar hot water: save roughly $300–$700 per year, depending on tariffs. • Gas to solar hot water installation: save about $250–$600 per year. • Old electric to modern electric hot water installation with good rooftop solar: save around $250–$500 per year.
These savings depend on the exact hot water system price / cost, how much hot water you use, and how well the system is set up with timers or solar diversion. Even so, it is clear why many locals see heat pump hot water vs solar hot water as a worthwhile comparison when planning their next hot water installation.

Hot Water Rebates, Tariffs & Savings
For Bunnaloo homeowners, there is growing interest in replacing old gas or electric hot water with efficient options like a heat pump hot water system, newer electric hot water system or a solar hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water heating system and heat pump units, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate. NSW programs can also offer additional support for efficient hot water NSW upgrades, and there are electric hot water system rebate options in some schemes when you move away from gas.
These hot water rebate NSW incentives can reduce the effective heat pump hot water price / cost or solar hot water price / cost by a substantial percentage, cutting payback periods to just a few years, especially if you already have solar. By using timers or smart controllers to run your electric hot water vs gas hot water during the middle of the day, or diverting excess solar into your tank, you can squeeze even more value from an energy efficient hot water system. When it is time for solar hot water repair, solar hot water tank replacement or general hot water repair, many locals take the opportunity to upgrade to what they see as the best hot water system Australia can offer for their needs, whether that is chromagen solar hot water, a premium sanden heat pump or a reliable rheem or rinnai unit.
