Hot water systems in Nine Mile
Across Nine Mile, more locals are rethinking their old gas and electric hot water system and switching to energy efficient hot water options. With a small, mostly owner‑occupied community (around 547 dwellings and more than 330 homes owned outright), and an average household size of about 2.1 people, many households are looking to cut running costs without sacrificing comfort. Upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a simple way to trim bills and future‑proof your home.
Nine Mile’s climate is well suited to efficient hot water. Nearby Coonooer Bridge records an average annual solar exposure of about 17.3 MJ/m² per day, or roughly 4.8 kWh/m²/day, which is strong support for both a solar hot water heating system and high‑performance heat pump hot water. For families on a median household income of around $932 a week, the annual hot water energy savings from replacing an older unit can make a real difference to the budget, especially for retirees and over‑65s who make up a large share of the postcode.
Most homes here are separate houses with three bedrooms, so hot water demand is steady but not extreme. That makes choosing the most efficient hot water system even more important. The right choice depends on your roof space, power supply and whether you already have solar PV. Many residents are comparing heat pump vs solar hot water, or weighing up solar hot water vs electric hot water when planning their next hot water installation. Well‑known brands such as Rheem heat pump hot water, Sanden heat pump units and Rinnai solar hot water are popular options, along with Rheem solar hot water and Chromagen solar hot water for those wanting a roof‑mounted solar hot water tank replacement.
Typical annual bill savings in Nine Mile can look like:
• Old electric to heat pump hot water system: $350–$700 per year • Gas to heat pump hot water system: $250–$550 per year • Gas to solar hot water system: $200–$500 per year • Old electric to modern electric hot water installation with rooftop solar: $200–$450 per year
These ranges will vary with usage, tariffs and how much solar you export versus use on site, but they show why many locals now see a heat pump hot water installation or solar hot water installation as a smart move. For some households, a modern, well‑insulated electric hot water installation still makes sense, particularly when paired with solar PV and off‑peak tariffs.

There have been 113 efficient hot water systems installed in the 3518 postcode, combining both heat pump and solar hot water installations.

This pattern shows a clear, ongoing interest in electrification, lower running costs and more energy efficient hot water system options as older units reach the end of their life and need hot water repair or replacement.
Hot Water Rebates, Tariffs & Savings
With energy prices on the rise, more Nine Mile households are looking to move away from gas and older electric hot water, towards options like a heat pump hot water system, solar hot water system or efficient electric hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) can reduce the upfront hot water system price for eligible heat pump and solar hot water systems, while Victorian hot water rebate programs often provide a separate heat pump hot water rebate or solar hot water rebate. In some cases there is also an electric hot water system rebate when replacing inefficient systems, helping bring the overall heat pump hot water price or solar hot water price down by a substantial percentage.
For many Nine Mile homes, these hot water rebate VIC programs, combined with smart tariffs and rooftop solar, can cut payback periods significantly. It is common to see hundreds of dollars per year shaved off bills when moving from electric hot water vs gas hot water to a high‑efficiency unit, especially if you use timers or solar diversion to run your hot water when the sun is shining.
