With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Sandfly and the 7150 area, 111 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Sandfly's climate delivering an average of 3.7 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot Water Demographics - Sandfly
Based on the Australian Bureau of Statistics 2021 Census (ABS), Sandfly has around 2,062 private dwellings, home to approximately 2,875 people. With an average household size of 2.4 people, and around 50 litres of hot water used per person each day in Australia, Sandfly households use approximately 120 litres of hot water daily, equating to a massive 0.2 million litres of hot water used across the suburb every single day.
Other census insights reinforce Sandfly's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Sandfly community is home to 224 couple families with children and 40 one-parent families, meaning a large proportion of households face substantial hot water demand. With 458 homes owned with a mortgage and 594 owned outright, many residents also have the homeownership and growing equity that make switching to efficient hot water systems a practical way to lower expenses.
Sandfly is converting hot water demand to efficient systems faster than many peers, with 5.4% of dwellings already upgraded.
Hot water systems in Sandfly
Across Sandfly and the 7150 area, more homeowners are swapping old gas and electric units for an energy efficient hot water system that actually suits the way they live. With most dwellings here being separate houses and an average household size of around 2.4 people, a well-sized hot water system can make a real dent in power bills without sacrificing comfort. Median household incomes are solid for a semi‑rural area, but with mortgages and living costs rising, it is no surprise more locals are asking about the best hot water system Australia can offer for long‑term savings.
Sandfly’s solar exposure averages about 13.2 MJ/m² a day – roughly 3.7 kWh/m² – which is strong enough to support both a solar hot water system and a modern heat pump hot water system. On clear summer days those numbers jump even higher, so using the sun for hot water is a logical next step after rooftop solar. Many homes already running PV are now looking at solar hot water vs electric hot water, or heat pump vs solar hot water, as a way to push energy bills down further and move towards an all‑electric home.
For a typical Sandfly family, hot water can be one of the biggest single energy users in the house. Older storage gas or resistive electric units are often the culprits. Upgrading to an energy efficient hot water system – whether a solar hot water heating system, a quality heat pump hot water system, or a well‑matched electric hot water system working with your solar – can slash that usage. Brands like Rheem heat pump hot water, Sanden heat pump units and Rinnai solar hot water systems are popular options locally, alongside Rheem solar hot water and Chromagen solar hot water for those wanting roof or ground‑mounted collectors with a tank.
Around Sandfly, there have been 111 efficient hot water installations recorded, combining both heat pump hot water installation and solar hot water installation. Install numbers rose strongly around 2009–2011, with 17 systems in 2009 and 14 each in 2010 and 2011, reflecting early interest in rebates and going off gas. More recent years show a steadier trickle of installs, but the pattern is clear: as people hear neighbours talk about lower bills and quieter, more reliable systems, interest in electrification and efficient hot water installation keeps growing.
When it comes to running costs, the right choice depends on your roof, budget and how you use hot water. A modern heat pump hot water system is usually the most efficient hot water system for Sandfly’s climate, pulling heat from the air rather than burning gas. A well‑designed solar hot water system with an electric booster can also work brilliantly here, especially if you have good north‑facing roof space. A newer electric hot water system paired with rooftop solar and a timer can still be a smart move if you want something simple and robust, and to take advantage of daytime solar generation.
Typical savings for Sandfly homes upgrading their hot water might look like this:
• Replacing an old electric hot water system with a heat pump: around $350–$700 a year off bills. • Switching from gas hot water to a heat pump: around $300–$600 a year saved, plus lower emissions. • Moving from gas hot water to a solar hot water heating system: around $250–$550 a year, depending on usage. • Upgrading an old electric unit to a modern electric hot water installation run mostly on solar: around $200–$450 a year.
Hot Water Rebates, Tariffs & Savings
There is growing interest in Sandfly in replacing ageing gas or electric units with efficient options like heat pumps, solar hot water and smart electric hot water systems. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront discount. On top of that, Tasmanian and national programs may offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate at times, all helping to reduce the hot water system price you pay on the day. With the right combination of incentives, the heat pump hot water price or solar hot water price can drop by a substantial percentage, bringing payback periods down to just a few years. Using timers or solar‑diversion controls so your electric or heat pump unit runs mainly on solar power can boost savings further and make solar hot water vs electric hot water a much easier decision.
If your current unit is rusty, running out of hot water, or you are simply curious about hot water repair versus full replacement, it is worth comparing hot water system cost options now rather than waiting for a failure. Solar hot water tank replacement can be rolled into a broader upgrade, and solar hot water repair or electric hot water repair is often a chance to rethink whether your system is still right for your home.
