In 3340, most homes are three‑ or four‑bedroom places, so a typical hot water installation will be sized for a medium to larger family. Hot water can easily account for a quarter of a home’s energy use, so choosing the most efficient hot water system has a big impact on overall bills. Local installers are seeing strong interest in brands like Rheem heat pump hot water and Sanden heat pump units for ultra‑efficient electric systems, along with Rheem solar hot water and Chromagen solar hot water for roof‑mounted solar hot water installation and solar hot water tank replacement when older units fail. For many, the best hot water system Australia‑wide is the one that balances upfront hot water system price with low running costs and simple hot water repair if anything goes wrong.
Typical bill savings in Bacchus Marsh look like this:
• Old electric to heat pump hot water system: save around $400–$800 per year • Gas to heat pump hot water: save roughly $300–$700 per year • Gas to solar hot water system: save about $250–$600 per year • Old electric to modern electric hot water installation with rooftop solar: save around $250–$500 per year
Over time, these savings matter for households with a median total household income of about $1,806 per week, especially when juggling mortgages and everyday costs.
Efficient hot water is not just a theory here – it is already happening. In Bacchus Marsh, 3,257 efficient hot water systems (heat pump and solar hot water installations) have been installed so far.

Hot Water Rebates, Tariffs & Savings
With many Bacchus Marsh homes still on older gas or resistive electric units, there is growing interest in switching to a heat pump hot water system, a more efficient electric hot water system or a solar hot water heating system. Homeowners here can usually access Australian Government Small‑scale Technology Certificates (STCs) that reduce the effective solar hot water price or heat pump hot water price at the point of sale. On top of that, state‑based programs in Victoria can offer a heat pump hot water rebate, solar hot water rebate and sometimes an electric hot water system rebate when replacing inefficient models. These hot water rebate vic incentives can cut the upfront hot water system cost by a substantial percentage, bringing quality systems like Rheem solar hot water, Rinnai solar hot water or a premium Sanden heat pump within reach.
When you combine rebates, STCs and self‑consuming your rooftop solar, payback periods for an efficient hot water upgrade can drop to just a few years. Using timers or smart controls to run your electric hot water system during the day, or divert excess solar into a heat pump, can further improve savings. For many households, that means hundreds of dollars off annual bills while also cutting emissions.
If you are in Bacchus Marsh and your current unit is old, noisy or running on gas, now is a good time to see whether a heat pump vs solar hot water, or even a modern electric hot water vs gas hot water option, suits your home.
