Greenhill’s elevated position and strong sunshine make it ideal for a solar hot water heating system or a high performance heat pump hot water system. The local weather station records an average annual solar exposure of about 16.7 MJ/m² per day, which is roughly 4.6 kWh of solar energy hitting each square metre daily. That is plenty of free energy to support solar hot water vs electric hot water, or to boost a heat pump so it runs more efficiently. When you upgrade an older gas or electric hot water system, the annual hot water energy savings in Greenhill can be substantial, especially for larger family homes with three or four bedrooms.
Across the 5140 postcode there have already been 26 efficient hot water installations, combining heat pumps and solar hot water installation projects. Installations peaked in the early 2000s, with solid years in 2003 and 2004, and steady activity through to 2017 and 2020. This pattern shows a long running interest in electrification and lower running costs, and as power prices rise, more Greenhill homeowners are revisiting options like heat pump vs solar hot water and solar hot water vs electric hot water to decide their next upgrade.
For a typical Greenhill household, hot water can be one of the biggest energy users, especially where older electric or gas systems are still in place. Swapping to an energy efficient hot water system can trim a good slice off your annual bills. While every home is different, realistic average savings often look like this:
• Old electric to heat pump hot water installation: save around $350–$700 per year on bills. • Gas to heat pump hot water system: save roughly $250–$600 per year. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation with rooftop solar: save around $200–$500 per year.
In the local market, brands like Rheem, Rinnai, Sanden and Chromagen are popular choices. You will see Rheem solar hot water and Rheem heat pump hot water systems on many roofs and in back yards across SA, while Rinnai solar hot water and Chromagen solar hot water units are common for those wanting a robust solar hot water tank replacement. For premium performance, a Sanden heat pump is often shortlisted as one of the best heat pump hot water system options in Australia, especially for households chasing the lowest possible running costs.
Hot water SA incentives make these upgrades even more attractive. Federal Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively cutting the upfront solar hot water price / cost or heat pump hot water price / cost by a meaningful amount at the point of sale. On top of this, state-based hot water rebate SA programs can add a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some schemes, further reducing the overall hot water system price / cost. When you combine rebates with rooftop solar and smart controls like timers or solar diversion, payback periods can shrink to just a few years, while ongoing savings of hundreds of dollars a year are realistic for many Greenhill homes.
If you are comparing electric hot water vs gas hot water, or working out the best hot water system Australia can offer your particular home, it pays to look closely at long term costs, reliability and available hot water rebate SA options. A quality solar hot water repair or hot water repair on a newer system can sometimes extend life, but if your unit is older, a full solar hot water tank replacement or new electric hot water installation may make more financial sense. Modern systems are designed to be the most efficient hot water system possible for their class, especially when paired with rooftop solar.
