She Oaks enjoys strong sunshine, with mean daily solar exposure of about 15 MJ/m², which works out to roughly 4.2 kWh of solar energy per square metre per day. That is excellent for both a solar hot water system and a heat pump hot water system, as they thrive on good solar conditions.

In a postcode dominated by owner-occupiers (well over 2,000 owned outright or with a mortgage), many residents are looking at the next logical step after rooftop solar: tackling hot water. Hot water can be one of the biggest energy users in the home, so choosing the most efficient hot water system you can afford really matters. For some homes that means a high-performance heat pump hot water system, such as a Sanden heat pump or Rheem heat pump hot water unit. Others prefer a roof-mounted solar hot water heating system from brands like Rheem solar hot water, Rinnai solar hot water or Chromagen solar hot water, often paired with an electric booster.
Across 3331 there have already been 1,411 efficient hot water systems installed, combining heat pump and solar hot water systems. Installations were modest in the early 2000s, then jumped sharply around 2008–2010, with a peak of 285 installs in 2009 as incentives ramped up. Since then, the yearly numbers have steadied, with 40–100 installs most years and ongoing activity through to 2024 and 2025. This steady trend shows growing local interest in electrification, moving away from gas hot water, and locking in lower running costs.
When you look at heat pump vs solar hot water, both can be part of an all-electric home strategy, especially if you already have rooftop solar. A quality heat pump hot water system price/cost is typically higher upfront than a basic electric hot water system, but the running costs are far lower. Likewise, a solar hot water price/cost can be offset by generous incentives. For many She Oaks homes, the best heat pump hot water system or best hot water system Australia-wide is the one that balances upfront hot water system price/cost, roof space, and family hot water usage.
Typical annual bill savings for She Oaks households can look like this:
• Old electric hot water to heat pump: save roughly $400–$800 per year. • Gas hot water to heat pump: save around $300–$600 per year. • Gas hot water to solar hot water: save about $250–$600 per year. • Old electric to modern electric hot water system with solar: save roughly $200–$500 per year.
