With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Armstrong and the 3377 area, 386 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Armstrong's climate delivering an average of 4.6 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Armstrong
Across Armstrong and the wider 3377 district, more locals are rethinking their hot water system as power prices rise and older gas units reach the end of their life. With an average household size of around 2.2 people and more than 2,600 homes either owned outright or with a mortgage, many households are in a good position to invest in an energy efficient hot water system that cuts bills and future‑proofs the home. The local climate helps too: Armstrong enjoys strong sunshine, with mean daily solar exposure around 16.4 MJ/m² (roughly 4.5–4.6 kWh per square metre per day), which suits both a modern heat pump hot water system and a quality solar hot water system.
For families and retirees alike, upgrading from an old gas or electric hot water system to a heat pump or solar hot water heating system can slash the energy used for hot water, which is often one of the biggest loads in the home. In a postcode where the median total household income is about $1,239 per week and many residents are on fixed incomes, the annual hot water energy savings from an efficient hot water upgrade can make a noticeable dent in quarterly bills. With a high share of separate houses and plenty of roof space, Armstrong homes are well suited to solar hot water installation, roof‑mounted collectors and compact heat pump hot water installation beside the house.
Locally, we see a mix of systems: some homes still running older gas storage units, others on basic electric hot water, and a growing number shifting to all‑electric homes with solar PV, a heat pump hot water system or a roof‑mounted solar hot water heating system. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular for efficient upgrades, while Rheem solar hot water and Chromagen solar hot water remain common choices when people want to maximise solar gains. For many households, the best hot water system Australia can offer is the one that balances upfront hot water system price with low running costs and reliable hot water repair support.
When you look at heat pump vs solar hot water, both can be the most efficient hot water system for Armstrong, depending on your roof, budget and whether you already have solar panels. A quality heat pump hot water system can run mainly on off‑peak or solar electricity and use a fraction of the energy of an old electric hot water system. A well‑designed solar hot water system with electric boost can deliver very low running costs, especially in summer. Either way, solar hot water vs electric hot water (old resistive tanks) is usually no contest on efficiency.
Typical upgrade savings around Armstrong look like this:
• Old electric to heat pump: save roughly $350–$700 per year on bills. • Gas storage to heat pump: save around $250–$500 per year. • Gas storage to solar hot water: save around $200–$450 per year. • Old electric to modern electric hot water system with solar: save about $200–$400 per year.
These ranges depend on household size, tariffs and how much hot water you use, but they give a feel for the potential. That is why many locals now ask about heat pump hot water price, solar hot water price and overall hot water system cost as part of a broader plan to electrify the home and cut running costs.
In Armstrong and the 3377 area, there have already been 386 efficient hot water systems installed, including both heat pump and solar hot water installation projects. Installations really took off around 2008–2011, with noticeable peaks, and there has been renewed growth in recent years, with 32 systems installed in 2024 and 27 already in 2025. This steady rise in hot water installation numbers shows how strongly local households are embracing energy efficient hot water system options, moving away from gas hot water and older electric units towards smarter, low‑running‑cost solutions.
Hot Water Rebates, Tariffs & Savings
Interest in replacing old gas or electric hot water with efficient options like heat pumps, solar hot water or modern electric hot water installation is growing fast in Armstrong VIC. Homeowners are keen to reduce bills, lock in more predictable running costs and make the most of their solar. 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. On top of that, Victorian state programs often provide a heat pump hot water rebate or solar hot water rebate, as well as an electric hot water system rebate in some schemes, which can take a substantial slice off the heat pump hot water cost or solar hot water price.
For Armstrong households, these hot water rebate VIC programs can effectively reduce system cost by a meaningful percentage and shorten payback periods to just a few years, especially when combined with rooftop solar. Many homes see hundreds of dollars per year in savings from an efficient hot water upgrade, and using timers or solar‑diversion controls to run your electric hot water system when the sun is shining can improve returns even further. With the right setup, an energy efficient hot water system can be the best heat pump hot water system or solar solution for your property, helping you get the most from your investment.
If your current unit is older, noisy, running out of hot water or needing frequent hot water repair, it is a good time to compare electric hot water vs gas hot water, think about solar hot water tank replacement or a full hot water upgrade, and look closely at hot water VIC tariffs. Many Armstrong homeowners are choosing to go all‑electric, pairing solar PV with a heat pump or solar hot water system to cut emissions and simplify their energy bills.
