Hot Water Systems in Willsden

Hot water systems in Willsden

Across Willsden and the wider 5700 area, more households are swapping old gas and ageing electric units for an energy efficient hot water system that is cheaper to run and kinder to the climate. With an average household size of about 2.2 people and more than 4,300 occupied dwellings, reliable hot water is a daily essential, but rising energy costs mean many locals are now asking whether a modern heat pump hot water system or solar hot water system could do the job for less.

Willsden’s sunny Upper Spencer Gulf climate is ideal for efficient hot water. The local weather station at Port Augusta Railway Station records around 19.2 MJ of solar energy a day on average – roughly 5.3 kWh/m²/day – which is excellent for both a solar hot water heating system and a high quality heat pump hot water installation. With many homes owned outright or with a mortgage and a median household income of about $1,199 a week, upgrading from older gas or resistive electric hot water to a more efficient hot water system is a logical next step to lock in long term savings. Annual hot water energy savings for Willsden homeowners can easily reach hundreds of dollars a year when moving to the most efficient hot water system options.

Local demand is driven by the mix of separate houses and smaller flats, plus a good share of families and older residents who value dependable hot water and lower bills. Hot water energy use can be one of the biggest single loads in a typical Willsden home, so choosing the best hot water system Australia has to offer for your needs really matters. Brands like Rheem and Rinnai are common choices, with Rheem solar hot water and Rheem heat pump hot water popular for all electric homes, while Rinnai solar hot water and Sanden heat pump units are often picked by those chasing the best heat pump hot water system for maximum efficiency.

When it comes to system sizes and savings, most Willsden households sit in the 2–4 bedroom range, so a 250–315 litre electric hot water system or equivalent size heat pump hot water system usually suits. A solar hot water tank replacement may be larger again for bigger families. Typical hot water system price or cost will vary, but energy savings can be significant. For example:

• Old electric to heat pump: save roughly $350–$700 per year on bills. • Gas to heat pump: save around $250–$600 per year, depending on usage. • Gas to solar hot water: save about $200–$500 per year. • Old electric to modern electric hot water with rooftop solar: save $250–$550 per year.

In Willsden, efficient hot water is already taking off. There have been around 840 efficient hot water installations recorded in the 5700 postcode, including both heat pump and solar hot water installation projects. Install numbers jumped in the early 2000s, with strong years in 2003, 2005 and 2010, and another spike around 2015 as rebates and interest in electrification grew. While yearly totals have been smaller more recently, installations in 2024 and 2025 show a steady stream of homeowners still choosing heat pump vs solar hot water solutions to cut running costs and move away from gas.

For many locals, the decision now is less about whether to upgrade and more about which technology to choose: heat pump hot water system, solar hot water vs electric hot water, or a modern electric hot water system paired with rooftop solar. A heat pump hot water price or cost is usually higher upfront than a basic electric hot water installation, but the lower running costs mean it can pay for itself in a few years, especially with a heat pump hot water rebate. A solar hot water price or cost can also be higher at the start, but the free energy from the sun and a generous solar hot water rebate can make it very attractive. Some households still prefer a straightforward electric hot water system rebate supported upgrade, especially if they already have a big solar array and use timers or solar diversion to heat water when the sun is shining.

Hot Water Rebates, Tariffs & Savings

Across Willsden SA, more people are replacing old gas or electric hot water with efficient options like heat pumps, newer electric units or a solar hot water system to get ready for an all electric home. Australian Government Small scale Technology Certificates (STCs) help reduce the upfront solar hot water price or cost and can also apply to eligible heat pump hot water installation jobs. On top of this, state based schemes can offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate, effectively cutting the system cost by a substantial percentage for many Willsden households.

With typical savings of hundreds of dollars per year off power or gas bills, and payback periods that shorten further when rebates and existing rooftop solar are combined, an energy efficient hot water system can be one of the smartest upgrades you make. Using timers or a simple controller to run a heat pump or electric unit during solar hours can boost savings even more and help you get the most from hot water SA tariffs and your own panels.
