That’s why more locals are comparing heat pump vs solar hot water and even solar hot water vs electric hot water to find the right fit. Brands like Rheem heat pump hot water, Sanden heat pump units and roof‑mounted systems from Rinnai solar hot water and Chromagen solar hot water are all common choices when people look for the best hot water system Australia offers for suburban blocks.
Typical annual bill savings in Redwood Park look like: • Old electric to heat pump hot water installation: save roughly $400–$800 per year • Gas to heat pump: save around $300–$600 per year • Gas to solar hot water installation: save about $250–$550 per year • Old electric to modern electric hot water installation with rooftop solar: save roughly $250–$500 per year, depending on usage and tariffs.
Efficient hot water is not just a theory here. There have already been 261 efficient hot water installations – mainly heat pump and solar hot water – recorded in the 5097 area. Installations climbed strongly around 2008–2011, when many households first moved away from older systems, and there has been steady ongoing interest through to 2024 and 2025.

Hot Water Rebates, Tariffs & Savings
Across Redwood Park, more residents are now planning to replace ageing gas units and old electric cylinders with a heat pump hot water system, a new electric hot water system or a solar hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) can lower the solar hot water price / cost and heat pump hot water price / cost, while state programs often provide a dedicated heat pump hot water rebate or solar hot water rebate. There are also schemes that can act like an electric hot water system rebate when you move away from gas hot water. For many Redwood Park households, these hot water rebate SA offers can cut the upfront hot water system price / cost by a substantial percentage and shorten the payback period to just a few years, especially if you run your system on daytime solar or use timers and solar diversion to maximise self‑consumption. Combine that with reliable hot water repair and solar hot water repair support, and the long‑term numbers start to stack up very favourably.
