Whether you are comparing heat pump vs solar hot water, or just want a straightforward electric hot water installation that works well with rooftop solar, there are options to suit most budgets and blocks.
In 2460, the typical 3‑bedroom home has moderate to high hot water demand, especially where there are kids or multi‑generational households. Hot water energy use can be a big slice of the power bill, so choosing the most efficient hot water system you can afford really matters. Many locals are now pairing an energy efficient hot water system with existing solar, or planning a future solar hot water installation when they re‑roof. Well known brands like Rheem solar hot water, Rinnai solar hot water, Chromagen solar hot water and premium heat pumps such as Sanden heat pump units are all seen in the area, alongside rheem heat pump hot water options for families wanting lower running costs without going fully solar.
To give a feel for potential savings in South Grafton, here are some typical annual bill reductions when you upgrade, depending on usage and tariffs:
• Old electric to heat pump hot water installation: save around $350–$700 per year. • Gas to heat pump hot water system: save roughly $250–$600 per year. • Gas to solar hot water system: save about $300–$650 per year. • Old electric to modern electric hot water installation with good rooftop solar: save around $250–$500 per year.
These figures will vary with your exact hot water system price or cost, local tariffs and how efficiently the system is set up, but they show why efficient hot water is becoming a popular upgrade.
South Grafton and the broader 2460 postcode have already seen 2,830 efficient hot water systems installed, including heat pump and solar hot water installation projects. Installations peaked around 2008–2011, with strong years like 2009 seeing over 550 systems go in as households chased rebates and solar hot water price or cost discounts.

When you are weighing up heat pump vs solar hot water, it is worth considering both upfront cost and running cost. A heat pump hot water price or cost is often lower than a full solar hot water tank replacement with roof collectors, and it works very well with solar PV using a timer. A solar hot water vs electric hot water comparison will usually show solar winning on running costs, but a modern electric hot water system connected to rooftop solar can still be a very energy efficient hot water system if it is controlled smartly. Many locals are also looking at electric hot water vs gas hot water as they plan for an all‑electric home.
