With an average household size of around 2.2 people and more than 7,500 separate houses, steady hot water demand is a given – especially for families and older residents. At the same time, power prices keep creeping up, so upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step.
Yallourn’s climate helps too. The local weather station records about 14.6 MJ/m² of solar exposure annually – roughly 4 kWh per square metre per day – which is plenty to drive a solar hot water heating system and boost the performance of heat pump hot water. For many owner‑occupiers (over 6,000 homes are owned outright or with a mortgage), shifting from electric hot water vs gas hot water to cleaner, cheaper options is a straightforward way to lock in long‑term savings. A well‑chosen system can deliver significant Annual Hot Water Energy Savings, cutting the share of hot water use in your overall household energy.
In the 3825 postcode, most dwellings are three‑bedroom homes, so a typical hot water installation is sized for small to medium families. Many are moving from old resistive cylinders to the most efficient hot water system they can reasonably afford. Brands like Rheem heat pump hot water and Sanden heat pump units are popular for low‑running‑cost upgrades, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices for a rooftop solar hot water installation. For some properties, a modern electric hot water installation paired with existing rooftop solar is still one of the best hot water system Australia options in terms of simplicity and payback.
Typical annual bill savings in Yallourn look like this:
• Old electric to heat pump hot water system: $400–$800 per year • Gas storage to heat pump: $300–$600 per year • Gas storage to solar hot water system: $250–$550 per year • Old electric to new electric hot water system with solar: $200–$500 per year
Those ranges will vary with your hot water system price, household size and how much hot water you use, but they give a good feel for what is possible with an energy efficient hot water system.

Hot Water Rebates, Tariffs & Savings
With many households on modest median incomes and mortgage repayments to juggle, upfront hot water system cost matters in Yallourn. That is where incentives help. Federal Small‑scale Technology Certificates (STCs) can reduce the effective heat pump hot water price or solar hot water price at the point of sale. On top of that, Victorian hot water rebate programs often support heat pump hot water rebate and solar hot water rebate offers, as well as some electric hot water system rebate options when replacing inefficient units. Together, these hot water rebate vic schemes can trim the installed cost by a substantial percentage and shorten payback to just a few years, especially if you use timers or solar diversion so your system runs when your PV is producing.
Whether you are weighing up heat pump vs solar hot water, or comparing solar hot water vs electric hot water, it pays to look at the full picture: running costs, rebates, roof space, and whether you might need solar hot water tank replacement or hot water repair in the near future. A good installer will also check tariffs and controls so you end up with the best heat pump hot water system or solar hot water heating system for your situation.
