Hot water systems in Frewville
Across Frewville, more homeowners are rethinking their hot water system and moving away from old gas and power‑hungry electric units. With energy prices climbing and many households on solid incomes, upgrading to an energy efficient hot water system such as a heat pump hot water system, solar hot water system or modern electric hot water system is becoming the obvious next step.
Frewville’s mix of separate houses and townhouses, plus over 5,000 dwellings across the 5063 postcode, means plenty of hot showers, dishwashers and loads of washing every day. The average household size is around 2.3 people, with many families and a good number of older residents on fixed incomes, so running costs really matter. Swapping an older gas or electric hot water system for a modern, efficient hot water upgrade can trim hundreds of dollars a year off bills, which makes a real difference when the median mortgage sits above $2,000 a month.
Local solar exposure is a big win here. Glenside’s weather station shows an average of about 17 MJ/m² of sun per day over the year, which is roughly 4.7 kWh/m²/day. That strong sunlight is ideal for a solar hot water heating system and also boosts the efficiency of a heat pump hot water system, especially when paired with rooftop solar. It is one of the reasons hot water SA homes are steadily shifting towards all‑electric, energy efficient hot water options.
In Frewville 5063, many homes are medium to large three‑bedroom properties, so hot water demand is steady. More efficient systems like Rheem heat pump hot water units and Sanden heat pump models are popular with families chasing the most efficient hot water system they can reasonably afford. For those who prefer roof collectors, brands such as Rheem solar hot water and Rinnai solar hot water, along with Chromagen solar hot water, are common choices for a reliable solar hot water installation or solar hot water tank replacement.
Typical annual bill savings in Frewville look like this:
• Old electric to heat pump hot water installation: save around $400–$800 per year. • Gas to heat pump vs solar hot water: often $300–$700 per year depending on usage. • Gas to solar hot water system: save roughly $250–$600 per year. • Old electric to modern electric hot water installation with good rooftop solar: about $300–$700 per year.

This trend shows growing local interest in electrification, lower running costs and cutting gas altogether, especially as people replace ageing cylinders with the best hot water system Australia can offer for their budget.
Hot Water Rebates, Tariffs & Savings
Frewville households are increasingly using hot water rebate SA programs to bring the hot water system price down. Federal incentives such as Small‑scale Technology Certificates (STCs) can apply to eligible solar hot water systems and heat pump hot water systems, while state‑based schemes often provide a heat pump hot water rebate or solar hot water rebate that can slice a substantial percentage off the upfront heat pump hot water price or solar hot water price. For some newer electric hot water system rebate offers, upgrading an old unit to a more efficient electric hot water installation can also attract support.
When you combine these rebates with solar, many Frewville homes see payback periods shrink to just a few years. Using timers or solar‑diversion controls to run an electric hot water system or heat pump during the middle of the day further increases savings, helping your energy efficient hot water system work in sync with your rooftop solar. For many households, solar hot water vs electric hot water is no longer about comfort, but about long‑term running costs and reliability, and electric hot water vs gas hot water is increasingly decided in favour of efficient, all‑electric homes.
