There have already been 84 efficient hot water systems installed in the area, combining heat pump and solar hot water installations. Installations peaked around 2009–2011, when 36 systems went in over just three years, and there has been a steady trickle of upgrades since, including new systems in 2018, 2023 and 2025. That pattern shows ongoing local interest in electrification, lower running costs and moving away from ageing gas hot water.
Typical annual bill savings in Spring Terrace look like:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water system: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water system with solar: $250–$500 per year
When you compare heat pump vs solar hot water, both can be the most efficient hot water system for different homes. A Sanden heat pump or other best heat pump hot water system can shine where roof space or orientation is tricky, while Rheem solar hot water, Rinnai solar hot water or Chromagen solar hot water suit homes with good north‑facing roof area. Many households mix these with PV solar to create a truly energy efficient hot water system that runs mostly on sunshine.
Hot Water Rebates, Tariffs & Savings
In NSW, Spring Terrace homeowners can often tap into a mix of Australian Government Small‑scale Technology Certificates (STCs) and state hot water rebate programs. These may apply to a heat pump hot water system, solar hot water system or even an efficient electric hot water system rebate when replacing old gas or resistive electric units. Together, STCs and state heat pump hot water rebate offers can effectively cut the upfront hot water system price by 20–40% in many cases, bringing the heat pump hot water price or solar hot water price much closer to a standard replacement.
With lower upfront hot water system cost and running costs, many homes see payback periods shrink to just a few years, especially when using timers or solar diversion to run an electric hot water system during the day. When you weigh up solar hot water vs electric hot water, or electric hot water vs gas hot water, the long‑term numbers increasingly favour efficient electric options. Add in options like rheem heat pump hot water or rheem solar hot water, and the best hot water system Australia‑wide for many regional homes is now all‑electric.
If your existing unit is more than 10–15 years old, rusting, or you are facing a solar hot water tank replacement or hot water repair, it is often smarter to consider a full hot water upgrade instead of another patch‑up. Modern systems are more reliable, quieter and far cheaper to run, particularly in a sunny, space‑rich area like Spring Terrace.
