Swapping from gas hot water to an energy efficient hot water system can deliver substantial Annual Hot Water Energy Savings for local households.
In 5037, a large share of homes have two or three bedrooms, which typically means steady hot water demand but not commercial‑scale usage. That makes choosing the most efficient hot water system – and the right size – crucial. Many North Plympton households still rely on gas or older resistive electric units. Upgrading to a heat pump hot water system or solar hot water vs electric hot water can reduce hot water energy use by more than half, especially when paired with rooftop solar. Brands like Rheem heat pump hot water, Sanden heat pump and EvoHeat are popular for all‑electric homes, while Rheem solar hot water and Rinnai solar hot water are common choices for a reliable solar hot water installation. For those comparing heat pump vs solar hot water, local installers can walk you through real‑world performance, roof space, noise and budget.
Average annual bill savings in North Plympton can look like:
• Old electric hot water system to heat pump hot water system: save about $400–$800 per year. • Gas hot water to heat pump hot water system: save about $300–$600 per year. • Gas hot water to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation using rooftop solar: save about $200–$500 per year.
Since 2001, there have been around 160 efficient hot water installations (heat pump and solar hot water) recorded in North Plympton.

When it comes to hot water system price or cost, there is a wide range. A quality heat pump hot water price or cost is usually higher upfront than a basic electric hot water installation, and a solar hot water price or cost can be higher again, especially if you include a large solar hot water tank replacement. However, the most efficient hot water system often pays for itself over time through lower bills. Local specialists can also help with hot water repair and solar hot water repair to extend the life of existing systems.
Hot Water Rebates, Tariffs & Savings
Across SA, including North Plympton, more households are replacing old gas or electric hot water with efficient options like heat pump hot water, modern electric hot water systems and solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) effectively act as a solar hot water rebate or heat pump hot water rebate, cutting the upfront solar hot water price or cost or heat pump hot water price or cost. South Australian schemes can also operate as a hot water rebate sa for eligible efficient systems, and some retailers offer additional discounts or tariff options for electric hot water vs gas hot water.
These rebates and discounts can reduce the system cost by a substantial percentage, sometimes slashing thousands off a larger solar hot water heating system. Combined with typical savings of hundreds of dollars a year, the payback period for a solar hot water vs electric hot water or gas upgrade can be shortened significantly. Using timers or solar‑diversion controls to run a hot water system during the middle of the day can squeeze even more value from rooftop solar and make an electric hot water system rebate go further.
If you are in North Plympton and your current unit is more than 10 years old, running out of hot water or costing a fortune to run, now is a good time to review your options.
