Hot water systems in Nullarbor
In Nullarbor, more locals are rethinking their old gas and electric hot water system and switching to energy‑efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an average household size of around 2.5 people and more than 1,400 dwellings across the 5690 postcode, hot water is a big slice of the power bill.

Nullarbor’s climate is made for efficient hot water. The Cook weather station records a mean daily solar exposure of about 19.6 MJ/m², which is roughly 5.4 kWh of sunshine per square metre per day over the year. That strong, consistent sun means a solar hot water heating system or quality heat pump hot water installation can perform very well, even through winter. With a solid mix of homes owned outright and with a mortgage, and a good number of rented properties, there is growing interest in cutting running costs and making hot water more reliable in this remote part of SA.
Across the 5690 area, most homes are separate houses with three bedrooms, so hot water demand is steady rather than extreme. In many of these homes, hot water energy use can be 20–30% of total household electricity. Swapping an ageing system for the most efficient hot water system you can reasonably afford can make a real dent in bills. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, whether you are looking at a rheem solar hot water setup, a rheem heat pump hot water unit, a rinnai solar hot water system or a premium sanden heat pump for maximum efficiency.
Typical annual bill savings in Nullarbor can look like this:
• Replacing an old electric hot water system with a heat pump hot water system: about $350–$700 per year. • Switching from gas to a heat pump hot water system: about $300–$600 per year. • Switching from gas to a solar hot water system: about $250–$550 per year. • Upgrading an old electric unit to a modern electric hot water system and running it from rooftop solar: about $250–$500 per year.
There have already been 290 efficient hot water installations (heat pump and solar) recorded in the 5690 postcode. Installations spiked in the mid‑2000s, with strong years in 2003, 2005 and 2008, then tailed off to a handful of systems per year more recently. That earlier surge shows how long Nullarbor households have been interested in electrification and lower running costs, and the slow but steady trickle since 2018 suggests a new wave of upgrades as older solar units reach the age where solar hot water repair is no longer economical and solar hot water tank replacement or a fresh heat pump hot water installation makes more sense.
Hot Water Rebates, Tariffs & Savings
Right now, there is renewed interest in hot water SA‑wide in replacing old gas or resistive electric units with efficient options such as heat pumps, high‑efficiency electric hot water or a solar hot water system in Nullarbor. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate. On top of that, state programs and occasional electric hot water system rebate offers in SA can further trim the heat pump hot water price / cost or solar hot water price / cost. For many households, these hot water rebate SA incentives can cut the hot water system price / cost by a substantial percentage and shorten the payback period to just a few years, especially if you use timers or solar diversion so your electric hot water installation runs mainly on your own solar. Over the life of the system, that can mean thousands saved compared with electric hot water vs gas hot water, solar hot water vs electric hot water or even heat pump vs solar hot water, depending on your roof, budget and tariff.
