A well‑sized heat pump hot water installation or solar hot water installation can dramatically reduce this share, especially when paired with rooftop solar. Popular brands in the area include Rheem heat pump hot water and Rheem solar hot water for reliability, Rinnai solar hot water and Sanden heat pump systems for ultra‑efficient performance.

Hot Water Rebates, Tariffs & Savings
For Humbug Scrub households considering heat pump vs solar hot water or even solar hot water vs electric hot water, rebates make the decision easier. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and many heat pump models, effectively reducing the solar hot water price / cost or heat pump hot water price / cost at the point of sale. South Australia also offers heat pump hot water rebate and solar hot water rebate options from time to time, and there may be an electric hot water system rebate for certain high‑efficiency units. Together, these hot water rebate SA programs can trim the upfront hot water system price / cost by a substantial percentage.
When you combine rebates with good tariffs, timers or solar diversion, it is common for an energy efficient hot water system to cut hundreds of dollars per year from bills, with payback periods often dropping to just a few years. Smart controls let you run your hot water SA‑wide during the sunniest part of the day, turning a standard electric hot water vs gas hot water comparison firmly in favour of all‑electric homes powered by renewables.
