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 Miltalie and the 5602 area, 67 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 Miltalie's climate delivering an average of 5.0 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 Miltalie
Around Miltalie, more locals are looking at upgrading their hot water system to something that is cheaper to run and easier to live with. With most homes in the 5602 area being separate houses and an average household size of about 2.3 people, a well‑sized heat pump hot water system, solar hot water system or modern electric hot water system can comfortably cover daily demand without wasting energy. Many households are on a fixed income, with median household income around $1,197 a week and a median age of 51, so keeping running costs down – especially for essentials like hot water – really matters.
Miltalie enjoys strong sunshine, with Cowell’s average annual solar exposure of about 17.9 MJ/m² per day, which works out to roughly 5 kWh of solar energy per square metre each day. That is excellent for both a solar hot water heating system and for running a heat pump hot water system efficiently during the day. As more residents move away from older gas or power‑hungry electric units, the annual hot water energy savings can be significant, especially when paired with rooftop solar. For many homes, hot water is one of the biggest single energy users, so upgrading is often the most logical next step after installing solar panels.
Across the 5602 postcode there are 503 occupied private dwellings, with a high share owned outright and relatively modest mortgage repayments. That makes Miltalie a prime spot for long‑term investments like an energy efficient hot water system that can quietly reduce bills year after year. Local installations already include brands such as Rheem heat pump hot water and Rheem solar hot water, along with Sanden heat pump and Rinnai solar hot water options, which are all popular choices when comparing the best hot water system Australia has to offer in regional areas.
Recent data shows 67 efficient hot water systems – mainly heat pump and solar hot water installations – recorded in the 5602 area over the past couple of decades. There was a noticeable burst of activity in the early 2000s, with peaks around 2003 and steady solar hot water installation numbers through to 2010, and smaller but ongoing heat pump hot water installation numbers more recently. This trend reflects a growing local interest in electrification, lower running costs and replacing ageing gas or off‑peak electric units with the most efficient hot water system people can reasonably afford.
For a typical Miltalie home, the hot water system price or cost depends on the technology, but so do the savings. As a guide, annual bill savings can look like this:
• Old electric hot water to heat pump: 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 $200–$550 per year. • Old electric to modern electric hot water system with rooftop solar: save roughly $200–$500 per year.
When comparing heat pump vs solar hot water, many Miltalie homes with good north‑facing roof space lean towards a solar hot water system with a roof or ground‑mounted solar hot water tank replacement, while shaded sites or properties wanting an all‑electric home often choose a high‑quality heat pump like a Sanden heat pump or premium Rheem heat pump hot water unit as the best heat pump hot water system for their needs. Others prefer a robust electric hot water system as a simple replacement, especially when they already have plenty of solar PV.
There is also strong support from government incentives for hot water SA wide. Federal Small‑scale Technology Certificates (STCs) effectively act as an upfront discount on eligible solar hot water heating systems and efficient heat pumps, reducing the solar hot water price or cost and the heat pump hot water price or cost. On top of that, South Australian programs periodically offer a solar hot water rebate or heat pump hot water rebate, and in some cases an electric hot water system rebate when you move away from gas. For many Miltalie households, these hot water rebate SA incentives can cut the installed cost by a substantial percentage and shorten payback to just a few years, especially if you also use timers or solar diversion so your hot water system runs mainly on your own solar power.
If your current unit is old, noisy, running out of hot water or costing a fortune, it is a great time to look at hot water SA options such as a new solar hot water vs electric hot water system, or even electric hot water vs gas hot water when planning a full electrification. Whether you need hot water installation for a new build, hot water repair on an existing system, solar hot water repair, or full solar hot water tank replacement, working with experienced local installers helps you choose the right size, brand and tariff. With Miltalie’s strong solar exposure and growing interest in sustainability, an energy efficient hot water system can cut bills, reduce emissions and future‑proof your home.
