Hot water systems in Arcadia
In Arcadia, more households are rethinking their old gas and electric hot water system and moving to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an average household size of about 2.9 people and mostly separate houses on larger blocks, hot water demand is solid, and so are the savings when you upgrade. Many homes are owned outright or with a mortgage, and with median household incomes above the NSW average, investing in long‑term energy savings simply makes sense.
Arcadia’s climate is ideal for efficient hot water. The local weather station at Galston records around 16.1 MJ/m² of solar exposure a day across the year, which is roughly 4.5 kWh/m² of sunshine daily. That strong sun helps a solar hot water heating system perform well, and also boosts a heat pump hot water system if it is running on solar power. When you look at annual hot water energy savings, shifting from older gas or resistive electric units to an energy efficient hot water system can trim hundreds of dollars a year off your bills, while cutting emissions and future‑proofing your home.
Across the 2159 postcode there are about 1,658 dwellings, most of them three‑plus bedroom family homes, so hot water is a big slice of overall energy use. In many homes, hot water can be 20–30% of the power bill. That is why more locals are comparing heat pump vs solar hot water, or solar hot water vs electric hot water, to find the most efficient hot water system for their household. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular options for those chasing the best heat pump hot water system or the best hot water system Australia can offer, while Rheem solar hot water and Chromagen solar hot water are common choices for a roof‑mounted solar hot water installation.
Typical annual bill savings in Arcadia look like this:
• Swapping an old electric hot water system to a heat pump hot water system: save around $400–$900 per year. • Changing gas hot water to a heat pump: save roughly $300–$700 per year. • Moving from gas to a solar hot water system: save about $250–$650 per year. • Upgrading an old electric hot water system to a modern electric hot water system powered by rooftop solar: save around $300–$800 per year.
Since 2001, there have been 262 efficient hot water installations (heat pump and solar) recorded in Arcadia and surrounds. Installations ramped up sharply around 2008–2010, peaking at 48 systems in 2009 and 32 in 2010, as early solar hot water rebate schemes took off. While numbers dipped after that first boom, recent years still show steady interest, with new systems going in every year through to 2024. This trend reflects a clear local shift towards electrification, lower running costs and more reliable hot water installation options.
Hot Water Rebates, Tariffs & Savings
Around Arcadia, more homeowners are replacing ageing gas units with a heat pump hot water system or a solar hot water system, or choosing a high‑efficiency electric hot water system when their old tank fails. Federal incentives such as Small‑scale Technology Certificates (STCs) help reduce the solar hot water price / cost and heat pump hot water price / cost. On top of that, NSW hot water rebate programs can provide 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. Together, these hot water rebate NSW schemes can slash the upfront hot water system price / cost by a substantial margin, often cutting payback times to just a few years, especially if you run your system on rooftop solar.
With the right set‑up, using timers or solar‑diversion controls, your energy efficient hot water system can soak up cheap daytime solar and further improve savings. For many Arcadia households, that means lower bills, better reliability and a quieter, more comfortable home.
