Grace Plains enjoys excellent solar exposure, with nearby Mallala averaging around 17.8 MJ/m² of sunshine a day – roughly 5 kWh/m². That strong sun makes both a solar hot water heating system and a heat pump hot water system perform well, especially for households already thinking about going all‑electric. With median household income of about $1,555 a week and many homes owned outright or with a mortgage, investing in the best hot water system Australia can offer is a logical next step, especially when you look at the annual hot water energy savings on offer.
In postcode 5502, most homes are three‑bedroom places, so showers, baths and laundry all add up. Hot water can easily be a quarter of total household energy use, particularly in older homes still running a basic electric hot water system or bottled gas hot water. Switching from electric hot water vs gas hot water to a modern, energy efficient hot water system such as Rheem heat pump hot water, a Sanden heat pump or a Rinnai solar hot water setup can dramatically trim running costs while keeping plenty of hot water on tap.
Typical annual bill savings in areas like Grace Plains look like this:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water system: save around $250–$500 per year. • Gas to solar hot water system: save around $200–$450 per year. • Old electric to modern electric hot water installation backed by rooftop solar: save around $250–$600 per year.
Brands such as Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are well known for solar hot water installation and solar hot water tank replacement, while premium systems like Sanden heat pump are often chosen as some of the best heat pump hot water system options for those chasing the most efficient hot water system possible.
Grace Plains has already seen 55 efficient hot water systems installed, combining heat pump hot water installation and solar hot water installation. Installations peaked through the 2000s, with steady numbers from 2002 to 2011, and a fresh system added again in 2024. That trend shows a growing local interest in hot water SA upgrades, electrification and lowering running costs, even in a small rural community.
When you compare heat pump vs solar hot water, both can work brilliantly in Grace Plains’ sunny climate. A heat pump hot water price / cost is often lower upfront than a full solar hot water price / cost, and it runs efficiently day or night. A solar hot water system can deliver very low running costs once installed, especially when paired with PV solar. For some homes, a modern electric hot water installation using timers or solar diversion is a smart middle ground. Understanding the true hot water system price / cost, including rebates and running costs, is the key to choosing the right solution.
Hot Water Rebates, Tariffs & Savings
Across Grace Plains, more households are looking to replace old gas or ageing electric units with efficient options like heat pumps, solar hot water or modern electric systems. Australian Government Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively acting as a solar hot water rebate or heat pump hot water rebate that cuts the upfront price. South Australian schemes can add further support, including an electric hot water system rebate in some programs, making an energy efficient hot water system far more affordable.
Depending on the system and your usage, rebates and discounts can reduce the system cost by a substantial percentage, often shaving years off the payback period. Many Grace Plains homes can save hundreds of dollars a year by moving to efficient hot water, and when you combine this with rooftop solar, smart tariffs, timers or solar diversion, the payback on a hot water upgrade can be surprisingly quick. For many, solar hot water vs electric hot water is no longer just about comfort – it is about long‑term savings and lower emissions, helped along by a solid hot water rebate SA homeowners can tap into.
