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 Eureka and the 3350 area, 3,601 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 Eureka'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 Eureka
In Eureka and across 3350, more locals are switching to energy efficient hot water systems to cut bills and move away from gas. With around 26,000 occupied dwellings in the postcode and an average household size of 2.4 people, reliable hot water is essential, but so are manageable running costs. Many homes still use older gas or electric units, so upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical next step.
Eureka’s climate actually suits efficient hot water technology better than many people realise. The nearby Kirks Reservoir weather station records average solar exposure of about 15.3 MJ/m² per day – roughly 4.25 kWh/m² – across the year. That steady sunlight supports both a solar hot water heating system and high performance heat pump hot water, especially when paired with rooftop solar. With median household income around $1,503 a week and mortgages sitting near $1,517 a month, households here are very conscious of energy costs, so choosing the most efficient hot water system can make a real dent in ongoing bills.
In 3350, separate houses dominate, with more than 22,000 standalone homes and a strong mix of owner occupiers and renters. Families and couples typically need a 250–315 litre hot water system, and hot water can account for up to a quarter of home energy use. That is why efficient options like Rheem heat pump hot water, Sanden heat pump units and Rinnai solar hot water are becoming more common, alongside brands such as Thermann and Solahart for solar hot water installation. For many households, the hot water system price or cost over its lifetime matters more than the sticker price.
Typical annual bill savings for Eureka homes can look like this:
• Old electric to heat pump hot water system: save around $400–$800 per year • Gas to heat pump hot water: save roughly $300–$600 per year • Gas to solar hot water system: save about $250–$550 per year • Old electric to modern electric hot water with rooftop solar: save around $250–$500 per year
Across Eureka and the wider postcode, there have already been 3,601 efficient hot water installations, including both heat pump hot water installation and solar hot water installation. Install numbers jumped sharply around 2008–2010, with 419 systems in 2009 alone, and have stayed solid ever since, with more than 100 installs most years right through to 2024. This steady stream of upgrades shows how strongly locals are embracing efficient hot water, electrification and lower running costs.
Hot Water Rebates, Tariffs & Savings
Right now there is growing interest in Eureka in replacing old gas or electric units with a more energy efficient hot water system, whether that is a heat pump, a new electric hot water system or a solar hot water heating system. Federal Small-scale Technology Certificates (STCs) apply to eligible systems, effectively acting like a solar hot water rebate or heat pump hot water rebate that reduces upfront cost. Victoria also offers state-based incentives that can stack on top of STCs, and in some cases an electric hot water system rebate when moving away from gas. These discounts can cut the effective heat pump hot water price or cost and solar hot water price or cost by a substantial percentage, often shaving years off the payback period. Combine rebates with solar, smart tariffs, timers or solar-diversion and you can save hundreds of dollars a year while enjoying one of the best hot water system Australia options for your home.
If your Eureka home still runs on an old gas unit or ageing cylinder, now is a good time to compare heat pump vs solar hot water, or even solar hot water vs electric hot water, and see which is the most efficient hot water system for your situation. Whether you need hot water installation, hot water repair, solar hot water repair or a solar hot water tank replacement, experienced local installers can guide you through brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and other best heat pump hot water system options.
