In a postcode like 5267, where three and four bedroom homes dominate, hot water demand is steady year-round. Many older properties still rely on gas or basic electric storage, which are among the most expensive ways to heat water. Swapping to the most efficient hot water system you can afford – whether that is a quality heat pump hot water installation, a roof-mounted solar hot water installation, or a modern electric hot water installation paired with solar – can trim hot water energy use dramatically.
Typical annual bill savings for Keith households can look like this:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water: save roughly $250–$600 per year. • Gas to solar hot water system: save about $300–$650 per year. • Old electric to new electric hot water system with rooftop solar: save about $250–$500 per year.

Installations peaked in the mid‑2000s, with standout years like 2003 and 2006, and smaller numbers continuing through to 2016. While the yearly numbers have been modest more recently, they show a steady interest in electrification, solar hot water vs electric hot water comparisons, and lowering running costs for hot water SA households.
For homeowners in Keith, the hot water system price or cost is only part of the story. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pumps, effectively acting as a solar hot water rebate or heat pump hot water rebate that is usually taken off the upfront invoice. South Australian programmes can also support efficient hot water SA upgrades, including electric hot water system rebate options in some schemes. Together, these hot water rebate SA incentives can reduce the heat pump hot water price or cost and solar hot water price or cost by a substantial percentage, often cutting payback periods to just a few years. Add smart controls, timers or solar diversion and you can squeeze even more value from your energy efficient hot water system.
