Across the 5155 postcode there have already been 219 efficient hot water installations, mostly heat pump and solar hot water installation projects. Install numbers climbed strongly through the late 2000s, peaking around 2008–2010, and while the last few years have been quieter, recent installs in 2024 and 2025 show interest in electrification and lower running costs is picking up again. Many homeowners are now looking at heat pump vs solar hot water as a way to replace ageing gas storage units and older electric cylinders before they fail.
For a typical Mount George family home with three or four bedrooms, a 250–315 litre heat pump hot water installation or solar hot water tank replacement will usually cover everyday needs. Hot water energy use can be one of the biggest single loads in a home, so even modest efficiency gains add up quickly. Well known brands like Rheem heat pump hot water and Sanden heat pump units are popular for premium efficiency, while Rinnai solar hot water and Chromagen solar hot water systems offer proven solar hot water repair and replacement options when existing systems reach the end of their life.
Here is what annual bill savings can look like with the right hot water installation in Mount George (actual results depend on tariffs, usage and whether you have solar):
• Old electric to heat pump hot water system: save roughly $400–$800 per year. • Gas storage to heat pump hot water: save around $300–$600 per year. • Gas storage to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation with solar: save roughly $250–$500 per year.
Hot water system price or cost varies a lot. A basic electric hot water installation can be relatively cheap up‑front, but running costs are higher. A quality heat pump hot water price or cost will be higher at the start, yet bills are much lower, especially if you run it during the day on solar. Solar hot water price or cost sits in a similar range to many heat pumps, and systems like Rheem solar hot water or Rinnai solar hot water are common choices for households wanting to maximise solar hot water vs electric hot water savings.
In South Australia, hot water sa rebates and incentives can make a real dent in the upfront cost. Federal Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively giving you a discount at the point of sale. On top of that, state‑based programs 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 gear. Combined, these hot water rebate sa offers can cut the system cost by a substantial percentage and shorten payback to just a few years, especially if you also have solar PV and use timers or smart controls to run your system when the sun is shining.
If your current unit is more than 10 years old, running out of hot water or needing regular hot water repair, it is worth comparing electric hot water vs gas hot water and looking closely at heat pump hot water vs solar hot water.
