With an average household size of around 2.5 people and a big share of homes owned outright or with a mortgage, hot water is a major running cost that families and retirees alike are looking to bring under control.
Warunda is well placed for efficient hot water upgrades. The local solar exposure at nearby Wanilla averages about 17.1 MJ/m² per day over the year, which works out to roughly 4.75 kWh/m² of sunshine daily. That strong sunlight helps a solar hot water heating system perform well and gives a heat pump hot water system plenty of free ambient energy to work with. When you combine that with median household incomes around $1,500 a week and many three‑ and four‑bedroom homes, it makes sense that upgrading from older gas or resistive electric units is becoming the logical next step. Annual hot water energy savings for Warunda homeowners moving to an energy efficient hot water system can easily reach hundreds of dollars, especially in busy family homes.
In the 5607 postcode there are 1,800‑plus occupied dwellings, many of them larger separate houses with decent roof space for solar. That suits both a roof‑mounted solar hot water installation and pairing a heat pump hot water installation with existing rooftop solar. Hot water energy use can be one of the biggest single loads in a typical Warunda home, so choosing the most efficient hot water system has a real impact on bills. Brands like Rheem and Rinnai are popular locally for both rheem solar hot water and rinnai solar hot water options, while premium heat pump units such as Sanden heat pump systems and efficient Chromagen solar hot water setups appeal to households chasing the best heat pump hot water system or simply the best hot water system Australia has to offer.
Typical annual bill savings for Warunda homes can look like:
• Old electric to heat pump: save roughly $350–$700 per year. • Gas to heat pump: save roughly $250–$600 per year. • Gas to solar hot water: save roughly $200–$500 per year. • Old electric to modern electric with solar: save roughly $200–$450 per year.
Recent local data shows 152 efficient hot water systems have already been installed in the 5607 area, covering both heat pump and solar hot water installation jobs.

Hot Water Rebates, Tariffs & Savings
Right now there is strong interest across Warunda in replacing old gas units with efficient heat pump hot water or switching from an ageing electric hot water system to either solar or a modern, well‑controlled electric hot water installation. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to both solar hot water systems and many heat pump models, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate. South Australian schemes can also reduce the heat pump hot water price / cost or solar hot water price / cost further, and in some cases there are electric hot water system rebate offers when moving away from gas. For many Warunda households, these hot water rebate sa programs can cut the system cost by a substantial percentage and bring payback down to just a few years, especially when combined with rooftop solar and smart timers or solar‑diversion controls. That also improves the equation for heat pump vs solar hot water and solar hot water vs electric hot water when you are comparing quotes.
