Installations peaked around 2009–2011, with another bump in recent years as more residents focus on electrification and lower running costs. While numbers dipped after the initial solar hot water rebate boom, steady installations from 2019 to 2024 show renewed interest in heat pump vs solar hot water options as people look for the most efficient hot water system to pair with their solar PV.
For homeowners in St Georges, SA, it is worth understanding how rebates and tariffs can improve the hot water system price. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible heat pump hot water systems and solar hot water systems, effectively cutting the upfront solar hot water price or heat pump hot water price by a substantial percentage at the point of sale. On top of that, South Australian schemes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when replacing old, inefficient units. These hot water rebate sa programs can knock hundreds off the initial hot water system cost, bringing payback periods down to just a few years, especially if you also have rooftop solar.
Using timers, smart controls or solar diversion can push savings even further by running a heat pump or electric hot water installation when your solar is generating. Many locals are also comparing electric hot water vs gas hot water, and solar hot water vs electric hot water, to decide which hot water SA option best matches their roof space, budget and lifestyle. When systems age, a solar hot water tank replacement or solar hot water repair can be a chance to reassess whether a new heat pump may now be the better value choice.
If your existing unit is getting noisy, rusty or unreliable, now is a smart time to look at a hot water installation or hot water repair in St Georges. With strong solar exposure, good local interest in sustainability and generous hot water rebate SA incentives, upgrading to a modern heat pump, solar or efficient electric system can cut bills, reduce emissions and future-proof your home.
