Replacing an older gas unit or a power‑hungry storage tank can trim a big chunk off annual hot water energy use, which is often the second‑largest load after heating and cooling.
Around Green Patch, we see a mix of options: some homes stay with electric hot water, but choose a more efficient electric hot water installation paired with rooftop solar; others move to a heat pump hot water installation or a solar hot water installation on the roof. Brands like Rheem and Rinnai are popular for both rheem solar hot water and rinnai solar hot water, while sanden heat pump and Thermann style systems are common choices for those chasing the best heat pump hot water system. For many households comparing heat pump vs solar hot water or even solar hot water vs electric hot water, the decision comes down to roof space, budget and whether they already have solar panels.
In the 5607 postcode there have been 152 efficient hot water installations – mainly heat pump and solar – recorded over the past couple of decades. Install numbers grew strongly around 2009–2010, with steady activity through the 2010s and new systems still going in through 2022–2025. That pattern reflects growing local interest in electrification, lower running costs and getting away from rising gas prices.

For a typical Green Patch home, the right upgrade can deliver meaningful savings on the hot water system price or cost over its life. As a guide, many households see average annual bill reductions like:
• Old electric to heat pump hot water system: $350–$700 per year • Gas storage to heat pump: $250–$550 per year • Gas storage to solar hot water system: $250–$600 per year • Old electric to modern electric hot water system with solar: $200–$450 per year
Choosing quality brands such as rheem heat pump hot water, sanden heat pump or chromagen solar hot water can also mean fewer call‑outs for hot water repair and better long‑term reliability. For those chasing the best hot water system Australia can offer, the most efficient hot water system is usually a well‑sized heat pump or solar hot water heating system backed by solar power and smart controls.
Hot Water Rebates, Tariffs & Savings
There is strong interest in hot water SA wide in replacing ageing gas or electric units with efficient alternatives. Green Patch homeowners can often access a mix of Australian Government incentives and state‑based hot water rebate SA programs. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively cutting the upfront solar hot water price or cost or heat pump hot water price or cost by a substantial percentage at the point of sale. South Australian schemes can also support heat pump hot water rebate and solar hot water rebate offers, and in some cases an electric hot water system rebate when shifting away from gas.
When you combine rebates with rooftop solar and smart tariff use, payback periods can shorten dramatically. Many households see hundreds of dollars a year off their bills, especially if they use timers or solar‑diversion to run an electric hot water system during the middle of the day.
