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 Avon and the 5501 area, 421 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 Avon'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 Avon

Across Avon and the wider 5501 farming district, more locals are rethinking their old hot water system and moving to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With most homes here being separate houses and an average household size of around 2.8 people, hot water demand is steady, and so are the power bills if you are still on an ageing gas or electric storage unit.

For a rural community where many households are paying a median mortgage of about $1,590 a month and living on a median household income of roughly $1,708 a week, cutting running costs without sacrificing comfort just makes sense. Upgrading from older gas or resistive electric to an energy efficient hot water system is one of the easiest ways to do it. A typical Avon home can save a sizeable chunk of its annual hot water energy use by switching to a heat pump hot water system or a solar hot water heating system, especially if you already have rooftop solar.

Avon’s climate is ideal for efficient hot water. The nearby Wild Horse Plains weather station records mean daily solar exposure of about 18 MJ/m², which is roughly 5 kWh/m² of sunshine per day over the year. That strong solar resource supports both a solar hot water system and high‑performance heat pump hot water, helping them run more efficiently and slash the effective hot water system cost over the life of the unit.

Within the 5501 postcode, families make up a large share of the 7,600‑plus residents, and many homes have three or four bedrooms. That means higher hot water demand, but also bigger opportunities for savings. Roughly speaking, hot water can account for a quarter of household energy use in electric homes, so choosing the most efficient hot water system you can afford is important.

When locals compare heat pump vs solar hot water, the decision often comes down to roof space, budget and whether you already have PV solar. Popular brands in the area include Sanden heat pump systems for ultra‑efficient heat pump hot water installation, Rheem heat pump hot water and Rheem solar hot water for reliable all‑round performance, and Rinnai solar hot water for roof‑mounted solar hot water installation. For some properties, Chromagen solar hot water is also a solid option. Many Avon homeowners are simply looking for the best hot water system Australia can offer for regional conditions, or even the best heat pump hot water system they can get within their budget.

To give you a feel for potential savings, here are typical average annual bill reductions for Avon households:

• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water installation with solar diversion: $200–$450 per year

In recent years, we have seen steady growth in efficient hot water in Avon. There have already been 421 efficient hot water installations recorded in the 5501 area, covering both heat pump and solar hot water installation projects. Installations climbed strongly through the 2000s, peaking around 2003 and 2009 with 40 systems each year, and remaining consistent through 2004–2010. While yearly numbers since 2015 have been smaller, there is still a clear trend of households choosing to electrify, move away from gas hot water, and lock in lower running costs with options like rheem solar hot water, rinnai solar hot water and premium sanden heat pump solutions. Ongoing hot water repair and solar hot water repair work also shows that people are keen to keep their efficient systems running at their best.

Even if you are just starting to think about hot water SA wide, Avon homeowners have good reasons to act now. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively reducing the upfront hot water system price by a meaningful margin. On top of that, state‑based hot water rebate SA programmes often include a heat pump hot water rebate, solar hot water rebate and sometimes an electric hot water system rebate when replacing old, inefficient units. Together, these can trim the heat pump hot water price or solar hot water price by thousands of dollars in some cases, bringing payback periods down to just a few years, especially if you are pairing your system with rooftop solar and using timers or solar diversion to maximise self‑consumption. In real terms, many Avon households can save hundreds of dollars per year, all while cutting emissions and future‑proofing against rising gas prices.

If your current unit is leaking, more than 10 years old, or you are weighing up solar hot water vs electric hot water or electric hot water vs gas hot water, it is a good time to explore a hot water upgrade. Whether you need electric hot water installation, solar hot water tank replacement, hot water repair or a full heat pump hot water installation, working with experienced local hot water SA installers is essential. Avon’s strong solar resource and growing interest in sustainability mean an energy efficient hot water system can reduce your bills, shrink your carbon footprint and add value to your home.
