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 Ettrema and the 2540 area, 4,586 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 Ettrema's climate delivering an average of 4.3 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 systems in Ettrema
Across Ettrema and the wider 2540 region, more households are shifting to energy efficient hot water systems – especially heat pump hot water, solar hot water and modern electric hot water systems. With an average household size of about 2.3 people and more than 18,000 occupied dwellings, reliable hot water is essential, but so is keeping power bills under control. Many homes here are owned outright or with a mortgage, so upgrading an older gas or electric hot water system is a logical next step to cut running costs and future proof the property.
Ettrema’s climate is well suited to efficient hot water. The local weather station at Grassy Gully records mean daily solar exposure of around 15.7 MJ/m², which is roughly 4.4 kWh/m² of sunshine a day across the year. That solid solar resource helps both a solar hot water system or solar hot water heating system and a quality heat pump hot water system perform well, especially when paired with rooftop solar. For many families and retirees in the 2540 postcode, hot water energy use is one of the biggest chunks of the power bill, so switching to an energy efficient hot water system can deliver meaningful savings every year.
In this part of NSW, most homes are separate houses with three or four bedrooms, so there is steady hot water demand from showers, washing and kitchen use. Many properties still run older gas or resistive electric hot water, even as neighbours move to all electric homes with solar hot water vs electric hot water or heat pump vs solar hot water carefully weighed up. A typical hot water system price or cost will depend on the size of the tank and whether you choose a heat pump hot water installation, solar hot water installation or electric hot water installation, but the running costs are where the big differences show up.
To give a rough guide to annual bill savings in the Ettrema area, households often see: • Old electric to heat pump hot water system: about $400–$800 a year saved • Gas to heat pump hot water system: about $300–$700 a year saved • Gas to solar hot water system: about $250–$600 a year saved • Old electric to modern electric hot water system with good solar: about $250–$500 a year saved
Brands like Rheem and Rinnai are common locally, with options ranging from rheem solar hot water and rheem heat pump hot water to rinnai solar hot water units that match well with family homes. Many homeowners looking for the best heat pump hot water system or the most efficient hot water system are also considering premium units such as the Sanden heat pump, while others compare chromagen solar hot water and similar systems to find the best hot water system Australia can offer for their budget.

As these systems age, there is also regular demand for hot water repair, solar hot water repair and solar hot water tank replacement to keep everything running smoothly.
Hot Water Rebates, Tariffs & Savings
For Ettrema homeowners, replacing an old gas or electric hot water system with a heat pump hot water system, a newer electric hot water system or a solar hot water system is becoming more attractive thanks to rebates. The Australian Government’s 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 and heat pump hot water price or cost. In NSW, additional state-based schemes and electric hot water system rebate offers can apply to certain efficient systems, further reducing the hot water system price or cost by a substantial percentage. When you factor in typical savings of hundreds of dollars per year off bills, the payback period can shrink dramatically, especially if you use timers or solar diversion so your energy efficient hot water system runs mainly on your own solar.
If you are in Ettrema and your current unit is old, noisy or running up big bills, it is a good time to check whether a hot water nsw upgrade makes sense. Whether you are comparing solar hot water vs electric hot water, looking at rheem solar hot water or Sanden heat pump options, or just need straightforward hot water repair, working with experienced local hot water installers is the safest way to go.
