Many homes in Bay Of Shoals already use solar power, and the local climate helps. The Kingscote weather station shows mean daily solar exposure of about 16.3 MJ/m² – roughly 4.5 kWh of sun per square metre per day over the year – which is excellent for a solar hot water heating system and also supports efficient heat pump performance.

In a postcode with about 1,430 occupied private dwellings and a high share of owned‑outright and mortgaged homes, it makes sense to think long term about running costs. Hot water can be one of the biggest energy users in the home, so choosing the most efficient hot water system you can is key. Brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water are all common choices for households looking for the best heat pump hot water system or the best hot water system Australia offers for local conditions.
When you compare heat pump vs solar hot water, both can dramatically cut bills compared with electric hot water vs gas hot water. Typical annual bill savings in Bay Of Shoals might look like:
• Old electric to heat pump hot water installation: $400–$800 per year • Gas to heat pump hot water system: $300–$700 per year • Gas to solar hot water installation: $250–$600 per year • Old electric to modern electric hot water installation with rooftop solar: $200–$500 per year

Installations peaked in the mid‑2000s, with strong years in 2004, 2005 and 2009, and there has been a recent uptick again with new systems going in during 2019, 2022 and 2024. This steady trend shows growing local interest in electrification, lower running costs and more sustainable hot water SA wide. As systems age, many of these homes will also look at solar hot water tank replacement or hot water repair to keep performance high.
Even if you are still on an older system, there is strong momentum in Bay Of Shoals towards replacing gas or ageing electric units with a heat pump hot water system, a new solar hot water system or a more efficient electric hot water system. Federal incentives like Small‑scale Technology Certificates (STCs), plus South Australian hot water rebate SA programs for heat pumps and some efficient electric hot water system rebate offers, can bring the hot water system price or solar hot water price / cost down significantly. In some cases, a heat pump hot water rebate or solar hot water rebate can cut the upfront heat pump hot water price / cost by a substantial percentage, and typical households can save hundreds of dollars a year on bills.
When you factor in solar hot water vs electric hot water, or a timer‑controlled electric hot water system running mostly on rooftop solar, the payback period can shorten even further. Using smart controls or solar‑diversion to heat water when the sun is shining can turn your system into a truly energy efficient hot water solution.
