Hot water systems in Mount Cole
Across Mount Cole and the wider 3377 area, more homes are swapping old gas and electric units for modern, energy efficient hot water systems. With an average household size of around 2.2 people and more than 2,600 owner‑occupied homes, many locals are looking for ways to cut running costs and future‑proof their properties. Upgrading your hot water system is one of the simplest, highest‑impact changes you can make, especially with the strong solar exposure Mount Cole enjoys.
The local Ben Nevis weather station records mean daily solar exposure of about 15.8 MJ/m², or roughly 4.4 kWh per square metre per day over the year. That solid sunlight helps a solar hot water system or heat pump hot water system perform well, even through cooler months. For families on a median household income of around $1,239 a week, shifting from older gas or resistive electric hot water to an energy efficient hot water system can free up hundreds of dollars a year, while also shrinking emissions.
In Mount Cole’s mostly separate houses, hot water demand is steady rather than extreme, which suits a well‑sized heat pump hot water installation or solar hot water installation perfectly. Many homes already have rooftop solar, so pairing a modern electric hot water system or heat pump with daytime solar makes a lot of sense. Compared with overall household energy use, hot water can easily be a quarter to a third of the bill, so improving your system has an outsized impact. When you compare heat pump vs solar hot water, both can be the most efficient hot water system option depending on your roof space, budget and when you use hot water.
Typical annual bill savings in Mount Cole look like:
• Old electric to heat pump hot water system: $350–$700 per year • Gas to heat pump hot water system: $250–$600 per year • Gas to solar hot water heating system: $250–$550 per year • Old electric to modern electric hot water with solar: $200–$450 per year
Locally, brands like Rheem, Rinnai, Sanden and Thermann are common choices. You will see Rheem solar hot water and Rinnai solar hot water on many roofs, while Rheem heat pump hot water and Sanden heat pump units are popular for all‑electric homes chasing the best heat pump hot water system performance. These sit alongside other trusted names such as Chromagen solar hot water and Solahart, giving Mount Cole households a strong range of options when comparing hot water system price, efficiency and warranty.
Efficient hot water is not new to the area. There have already been 386 efficient hot water systems installed in the 3377 postcode, combining heat pump and solar hot water installations. Install numbers were modest in the early 2000s, then jumped sharply around 2008–2011 as solar hot water rebates and incentives kicked in. After a quieter period, installations have risen again, with strong years in 2022–2025 as more residents focus on electrification, lower running costs and moving away from gas hot water. This steady growth shows how interest in hot water VIC upgrades is becoming mainstream.
Hot Water Rebates, Tariffs & Savings
Around Mount Cole, more people are replacing old gas units or ageing cylinders with efficient options like heat pumps, modern electric hot water systems and solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively reducing the solar hot water price or heat pump hot water price at the point of sale. On top of that, Victorian hot water rebate VIC programs can support heat pump hot water installation and sometimes solar hot water installation too.
These hot water rebate VIC schemes and the national solar hot water rebate or heat pump hot water rebate can cut the upfront hot water system cost or solar hot water price by a substantial percentage. When you add in an electric hot water system rebate and run your unit on a solar‑friendly tariff or timer, many Mount Cole households see payback periods of only a few years, with typical savings of hundreds of dollars per year. Smart controls, timers and solar‑diversion can shift your electric hot water vs gas hot water running costs even further in your favour, especially if you already have rooftop solar.
If your current unit is more than 10 years old, running on gas, or you are facing a solar hot water tank replacement or hot water repair, it is a great time to review your options. Whether you are weighing up solar hot water vs electric hot water, comparing hot water system price, or simply want the best hot water system Australia can offer for your budget, Mount Cole’s solar exposure and growing interest in sustainability make an upgrade a smart move.
