Hot water systems in Glenunga
Across Glenunga, more homeowners are rethinking their old gas and electric hot water system and switching to efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With average household sizes around 2.6 people and more than 2,900 residents over 65, reliable, low‑running‑cost hot water is a big deal for local families and downsizers alike.
Glenunga’s strong sunshine is a big plus. The nearby Glenside weather station records around 17 MJ/m² of solar exposure a day on average, which is roughly 4.7 kWh/m². That is ideal for a solar hot water heating system and also helps a heat pump hot water system run more efficiently, especially when paired with rooftop solar. In a suburb where over 1,600 homes are owned outright and more than 1,300 are mortgaged, upgrading from older gas or resistive electric units to an energy efficient hot water system is a logical way to cut bills and protect property value. Many Glenunga households can save hundreds of dollars each year in hot water energy costs alone.
With 3,795 occupied private dwellings and a lot of three‑ and four‑bedroom homes, hot water demand is steady. For many families, hot water energy use can be 20–30% of total household electricity, so choosing the most efficient hot water system really matters. Local installers regularly work with brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water to match systems to Glenunga’s roof space, orientation and water use. For some, the best hot water system Australia can offer will be a high‑efficiency heat pump; for others, a rheem solar hot water or rinnai solar hot water setup with a solar hot water tank replacement makes more sense.
Typical annual bill savings in Glenunga look like this:
• Old electric to quality heat pump hot water installation: $400–$800 per year • Gas to heat pump hot water system: $300–$600 per year • Gas to solar hot water installation: $250–$550 per year • Old electric to modern electric hot water installation with rooftop solar: $200–$500 per year
These ranges depend on tariffs, usage and whether you use timers or solar diversion, but they show why heat pump vs solar hot water is now a serious question for many Glenunga households. For some, solar hot water vs electric hot water with solar PV will come down to roof layout, budget and how long they plan to stay in the home.
Glenunga has already seen 229 efficient hot water installations, combining heat pump and solar hot water installation projects. Uptake peaked around 2009–2011 with more than 60 systems installed over those three years, and there has been a steady trickle of new installs through to 2024. This pattern reflects growing interest in electrification, lower running costs and moving away from gas hot water, especially as more solar is added to local roofs. Each new system helps build community hot water energy savings and demonstrates what the most efficient hot water system options can do in real homes.
Hot Water Rebates, Tariffs & Savings
Across SA, including Glenunga, there is strong interest in replacing old gas or electric hot water with efficient alternatives. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump hot water and solar hot water systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate. South Australian schemes can also support heat pump hot water price / cost reductions, and some offers extend to an electric hot water system rebate when upgrading from gas.
These hot water rebate SA programs can shave a substantial percentage off the solar hot water price / cost or heat pump hot water price / cost, bringing the best heat pump hot water system or a quality solar hot water system within reach. With rebates plus solar, payback periods can drop to as little as three to six years in some cases, especially if you use timers or solar‑diversion to maximise daytime heating. Over the life of the system, that can mean thousands of dollars saved, plus lower emissions and less exposure to rising gas prices.
If your current unit is older, noisy or needing regular hot water repair, it may be time to compare electric hot water vs gas hot water and look at hot water SA upgrade options. Local specialists can assess whether a sanden heat pump, rheem solar hot water, chromagen solar hot water or other energy efficient hot water system is right for you, and can also handle hot water repair, solar hot water repair and solar hot water tank replacement when needed.
If you live in Glenunga and want to future‑proof your home, now is a smart time to review your hot water system price, running costs and carbon footprint. With strong local solar, solid household incomes and growing interest in sustainability, efficient hot water systems can help you cut bills, reduce emissions and move towards an all‑electric home.
