The 5116 postcode, covering Evanston, Evanston Gardens, Evanston Park, Evanston South and Hillier and surrounding areas, is home to around 4,474 households. 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 Evanston and the 5116 area, 212 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 Evanston'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 Evanston
In Evanston, more households are switching to energy efficient hot water systems to keep bills down and comfort up. With around 4,200 occupied dwellings and an average household size of 2.4 people, hot water makes up a big share of power use. Many locals are paying off mortgages on older homes, so upgrading from tired gas or electric units to a modern hot water system is a smart way to free up cash flow.
Evanston’s strong sunshine is a big advantage. The area averages about 17.6 MJ/m² of solar exposure a day over the year – roughly 4.9 kWh/m² – which is excellent for both a solar hot water system and a heat pump hot water system. That solar resource, combined with solid median household incomes and plenty of separate houses with roof space, means heat pump hot water installation and solar hot water installation can deliver serious annual hot water energy savings for local homeowners.
Across 5116, families and downsizers alike are looking for the most efficient hot water system they can afford. A modern heat pump hot water system, such as a Sanden heat pump or Rheem heat pump hot water unit, can slash usage compared with an old electric hot water system. Quality brands like Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices for a solar hot water heating system, while many still prefer a straightforward electric hot water installation paired with rooftop solar. Locals weigh up heat pump vs solar hot water and solar hot water vs electric hot water based on roof space, budget and when they use their hot water.
In Evanston 5116, efficient hot water systems installed so far already show the trend. There have been 212 heat pump and solar hot water installations recorded, with strong years around 2008–2010 when annual installs peaked above 20. While numbers have been smaller more recently, steady installations through to 2025 reflect ongoing interest in electrification, lower running costs and cleaner energy efficient hot water system options. As more homes add solar, pairing it with an efficient hot water upgrade is becoming the logical next step.
Typical annual bill savings for Evanston households can look like this:
• Old electric to heat pump: save about $350–$700 per year • Gas to heat pump: save about $250–$600 per year • Gas to solar hot water: save about $200–$500 per year • Old electric to modern electric with solar: save about $200–$450 per year
Local homeowners also keep a close eye on hot water system price and ongoing costs. A heat pump hot water price may be higher upfront than a basic electric unit, but rebates and lower running costs usually mean a faster payback. Solar hot water price and solar hot water tank replacement costs vary with roof layout and tank size, while electric hot water system price points remain attractive for tight budgets. Comparing heat pump hot water cost, solar hot water price and long term electricity bills helps find the best hot water system Australia can offer for your situation.
Hot Water Rebates, Tariffs & Savings
For hot water SA households, rebates are a major drawcard. The Australian Government’s Small-scale Technology Certificates (STCs) reduce the upfront solar hot water cost or heat pump hot water cost, and South Australian heat pump hot water rebate and solar hot water rebate programs can further cut the hot water system price. There are also schemes that effectively act as an electric hot water system rebate when you replace an inefficient unit with a high-performance model. In Evanston, these incentives can trim the installed cost by a substantial percentage and shorten payback to just a few years, especially if you use timers or solar diversion to heat water when your PV system is generating.
Whether you need hot water installation for a renovation, hot water repair on an ageing unit, or full solar hot water repair and upgrade, it pays to compare electric hot water vs gas hot water and consider moving to an all-electric home. With rising interest in sustainability and hot water rebate SA programs, Evanston households can cut emissions and future proof their properties.
