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 Erica and the 3825 area, 1,023 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 Erica's climate delivering an average of 4.0 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 Erica
Across Erica and the wider 3825 area, more households are switching to energy efficient hot water systems to keep bills under control without sacrificing comfort. With an average household size of around 2.2 people and a big share of homes owned outright or with a mortgage, many locals are looking at long-term savings from a modern hot water system rather than pouring money into ageing gas or off-peak units. Annual hot water energy savings can be significant when you move from an old electric hot water system or gas hot water to a quality heat pump hot water system or solar hot water system.
Erica’s climate helps. The town enjoys mean daily solar exposure of about 14.5 MJ/m², or roughly 4 kWh per square metre per day across the year, which is solid for both a solar hot water heating system and efficient heat pump hot water. In an area with more than 8,700 occupied dwellings and a median household income that rewards smart upgrades, shifting from older gas or resistive electric to an energy efficient hot water system is a logical next step. Many homes already using rooftop solar find that solar hot water vs electric hot water from the grid is an easy win, especially when combined with timers or solar-diversion controls.
Around Erica, demand varies from compact units for couples to larger systems for three and four bedroom family homes, but hot water energy use is still one of the biggest chunks of a typical power bill. That is why more locals are comparing heat pump vs solar hot water, or even a modern electric hot water installation matched to rooftop PV. Trusted brands like Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and premium Sanden heat pump units are all common options when people look for the best hot water system Australia can offer for cold mornings and frosty winters.
Average annual savings will depend on your roof, tariff and how much hot water you use, but typical ranges for Erica look like this:
• Old electric to heat pump hot water system: about $400–$900 per year • Gas hot water to heat pump: about $300–$700 per year • Gas to solar hot water system: about $250–$650 per year • Old electric to modern electric hot water system with solar: about $250–$600 per year
In total, around 1,023 efficient hot water installations (heat pump and solar hot water installation combined) have already gone in across the 3825 postcode. Install numbers were modest in the early 2000s, then climbed sharply from 2007 to 2011 as rebates kicked in, with steady interest ever since. Recent years show strong growth, with installations in 2020, 2021, 2022, 2023 and 2024 all well above earlier levels. That trend tells you a lot: Erica households are serious about electrification, lower running costs and getting away from volatile gas prices, while keeping reliable hot water VIC winters demand.
Hot Water Rebates, Tariffs & Savings
For Erica homeowners, there is growing interest in replacing old gas or electric units with a heat pump hot water installation, solar hot water installation or at least a more efficient electric hot water installation that works well with rooftop solar. Federal incentives such as Small-scale Technology Certificates (STCs) help cut the solar hot water price / cost and heat pump hot water price / cost, while Victorian state schemes can provide a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate for eligible upgrades. These hot water rebate VIC programs can slice a substantial percentage off the upfront hot water system price / cost, especially when combined with installer discounts. For many Erica homes, that means hundreds of dollars a year off bills and payback periods that can drop to just a few years, particularly when you use timers or solar-diversion to run your most efficient hot water system when your panels are generating.
