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 Cunningham and the 5571 area, 87 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 Cunningham's climate delivering an average of 4.9 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 Cunningham
Across Cunningham and the wider 5571 district, more homeowners are rethinking their old gas and electric hot water systems and moving to efficient options like a modern heat pump hot water system, solar hot water system or upgraded electric hot water system. With an average household size of around two people and a median age of 61, many locals are focused on comfort, reliability and keeping running costs under control in retirement and semi‑retirement. Upgrading your hot water system is one of the simplest ways to lock in long‑term energy savings.
Cunningham’s climate is well suited to efficient hot water. The nearby Petersville weather station records mean daily solar exposure of about 17.7 MJ/m², which works out to roughly 4.9 kWh/m² of sunshine a day over the year. That strong solar resource supports both a solar hot water heating system on the roof and a high‑quality heat pump hot water installation, as both technologies perform best with plenty of sun. With 884 occupied private dwellings and a large share owned outright, many households are in a good position to invest in an energy efficient hot water system that cuts bills and future‑proofs the home.
In the 5571 area, demand is driven by detached homes with two, three and four bedrooms, where hot showers, dishwashing and laundry add up quickly. For many properties, hot water can be 20–30% of total household energy use, so choosing the most efficient hot water system really matters. Locals weighing up heat pump vs solar hot water are often comparing day‑to‑day running costs, roof space and how well the system will pair with existing or planned rooftop solar. Others are looking at solar hot water vs electric hot water, especially when replacing an ageing gas unit and moving towards an all‑electric home.
When it comes to brands, you will often see Rheem solar hot water and Rheem heat pump hot water units installed across regional SA, along with Rinnai solar hot water and premium Sanden heat pump systems for those chasing the best heat pump hot water system on the market. Many households also consider Chromagen solar hot water or other reliable options when they need a solar hot water tank replacement or a full solar hot water installation. The best hot water system Australia‑wide for your home will depend on your roof, budget, water use and whether you already have solar panels.
Recent data shows 87 efficient hot water systems have been installed in the Cunningham postcode, combining heat pump hot water installation and solar hot water installation over the past couple of decades. Installations peaked in years like 2003, 2009 and 2011, when incentives were strong, with a steady trickle of hot water installation work continuing more recently as older systems fail. This pattern reflects growing local interest in electrification, lower running costs and reducing exposure to rising gas prices. Alongside new systems, there is ongoing demand for hot water repair and solar hot water repair to keep existing units running efficiently.
Typical annual bill savings for Cunningham households switching to efficient hot water are substantial:
• Old electric to heat pump hot water system: save roughly $350–$700 per year • Gas to heat pump hot water system: save around $250–$600 per year • Gas to solar hot water system: save about $300–$650 per year • Old electric to modern electric hot water installation with rooftop solar: save about $250–$500 per year
These are general ranges, but they illustrate how a more efficient hot water system price or cost can pay itself back over time. A quality heat pump hot water price or cost is usually higher upfront than a basic electric hot water installation, but the lower running costs and available rebates often make the overall numbers stack up well. Likewise, a solar hot water price or cost is offset by lower bills and strong performance in Cunningham’s sunny climate.
Hot Water Rebates, Tariffs & Savings
Across SA, including Cunningham, more residents are replacing tired gas or resistive electric units with a heat pump hot water system, solar hot water heating system or high‑efficiency electric hot water system. Australian Government incentives such as Small‑scale Technology Certificates (STCs) apply to eligible systems, effectively acting as an upfront discount off the hot water system price. On top of that, state‑based schemes can deliver a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate for certain efficient models. For many Cunningham households, these hot water rebate sa programs can trim the installed cost by a significant percentage, shortening payback periods to just a few years.
Because many locals already have or are considering rooftop solar, combining a heat pump or efficient electric system with solar‑aware timers or diversion controls can push savings even further. It is common to see total hot water energy use slashed by more than half, with hundreds of dollars a year kept in your pocket instead of going to your retailer. When you add in the environmental benefits and the security of moving away from volatile gas prices, an energy efficient hot water system quickly becomes the most efficient hot water system choice for many Cunningham homes.
If you live in Cunningham and your current unit is older, noisy, running out of hot water or simply costing too much to run, now is a smart time to look at a hot water upgrade.
