Rosedale benefits from strong solar exposure, with the nearby Turretfield Research Centre recording about 17.4 MJ/m² of sunshine per day on average – roughly 4.8 kWh/m²/day. That is ideal for both heat pump hot water and a solar hot water heating system, helping them run efficiently and slash running costs. With most households either owning outright or paying a mortgage, and a solid median household income, many owners are weighing up long‑term energy savings and the annual hot water energy savings they can unlock by moving away from old gas units.
In a postcode of mainly three‑ and four‑bedroom homes, hot water demand is steady, especially for the 49 couple‑with‑kids families and growing number of over‑65s who value reliability. Hot water energy use can be one of the biggest single loads in a home, so upgrading to the most efficient hot water system you can reasonably afford makes sense. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are becoming more visible across South Australia, alongside options like Chromagen solar hot water and rheem solar hot water packages for those wanting to pair a solar hot water tank replacement with an existing rooftop PV system.
Typical savings for Rosedale homes moving to an energy efficient hot water system can look like:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year on bills. • Gas to heat pump vs solar hot water: either option can often save $250–$600 per year, depending on usage. • Gas to solar hot water installation with PV boost: save around $300–$650 per year. • Old electric to modern electric hot water installation run mostly on solar: save $250–$500 per year.
Recent data shows 33 efficient hot water systems (heat pump and solar hot water installations combined) have already been installed in the 5350 postcode. Install numbers have stepped up in years like 2015 and again with new installs in 2022, 2024 and 2025, reflecting growing interest in electrification, lower running costs and cleaner hot water in Rosedale. As more homes add solar, questions around solar hot water vs electric hot water, and which is the best heat pump hot water system for local conditions, are becoming common.
When comparing options, it is worth looking at the full hot water system price, including installation and any hot water repair or upgrade work needed on pipework or switchboards. A quality heat pump hot water price might look higher upfront than a basic electric hot water system, but once you factor in rebates and lower running costs, the overall hot water system cost over ten years can be far lower. Many locals are also asking about electric hot water vs gas hot water, especially as gas prices rise and more households aim for all‑electric homes powered by rooftop solar.
Hot Water Rebates, Tariffs & Savings
In Rosedale, interest is growing in replacing old gas or electric units with efficient options like a heat pump hot water system, a modern electric hot water system or a solar hot water system that works hand‑in‑hand with rooftop solar. Australian Government Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount off the solar hot water price or heat pump hot water price. On top of that, South Australian schemes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when you move away from gas.
For Rosedale homeowners, these incentives can trim the installed solar hot water cost or heat pump hot water cost by a substantial percentage, often cutting payback periods from ten years down to as little as four to seven years, especially when paired with solar PV. Using timers or smart controls to run your electric or heat pump system during solar hours can boost savings further. With the right tariff and setup, an energy efficient hot water system can quietly shave hundreds of dollars a year off your bills while reducing emissions.
