Hot Water Systems in Berwick
The 3806 postcode, covering Berwick and Harkaway and surrounding areas, is home to around 17,781 households. 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 Berwick and the 3806 area, 3,817 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 Berwick'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 Berwick
Across Berwick, more homeowners are rethinking their old gas and electric units and upgrading to a modern hot water system that is cheaper to run and kinder to the environment. With an average household size of about 2.9 people and more than 17,000 dwellings in the 3806 postcode, hot water demand is high, especially for busy families. Rising energy costs mean sticking with an inefficient electric hot water system or ageing gas hot water is getting harder to justify when heat pump hot water and solar hot water are now readily available.
Berwick’s climate helps, too. Local solar data from Buchanan Road shows mean daily solar exposure of around 14.5 MJ/m², which works out to roughly 4 kWh/m² of sunshine a day over the year. That is strong support for both a solar hot water system and a heat pump hot water system, because there is plenty of free solar energy to tap into. Combine that with solid median household incomes and a high proportion of homes owned with a mortgage, and upgrading to an energy efficient hot water system becomes a logical next step for cutting bills and improving comfort.
In a typical Berwick home, hot water can be one of the biggest energy users after heating and cooling, especially in larger three and four bedroom houses. Swapping an old electric hot water system for a high-performance heat pump hot water installation or a solar hot water heating system can dramatically cut running costs. Brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and Thermann are common choices locally, offering options from premium Japanese-style heat pump hot water through to affordable roof-mounted solar hot water installation and efficient electric hot water installation for all-electric homes.
Average annual bill savings for Berwick households can look like this:
• Old electric to quality heat pump hot water system: $400–$900 per year • Gas hot water to heat pump hot water: $300–$700 per year • Gas hot water to solar hot water system: $250–$650 per year • Old electric to modern electric hot water with rooftop solar: $250–$600 per year
Over time, that sort of saving makes the hot water system price or cost of upgrading much easier to swallow. Many locals are also weighing up heat pump vs solar hot water and solar hot water vs electric hot water to find the most efficient hot water system for their roof space, budget and household size. For some, the best hot water system Australia can offer might be a premium Sanden heat pump; for others, a reliable Rheem heat pump hot water or Chromagen solar hot water setup paired with existing solar panels is the sweet spot.
Recent installation data shows how quickly Berwick is embracing efficient hot water. There have been 3,817 efficient hot water installations (heat pump and solar) recorded in the 3806 postcode, climbing from just a handful of systems in the early 2000s to hundreds of installs each year since about 2008. The strong numbers through 2020–2024 highlight growing interest in electrification, lower running costs and moving away from gas, as households look for the best heat pump hot water system or solar hot water tank replacement to future-proof their homes.
Hot Water Rebates, Tariffs & Savings
For homeowners considering hot water VIC wide, the combination of federal and state incentives is a major driver. The Australian Government’s Small-scale Technology Certificates (STCs) reduce the upfront solar hot water price or cost and heat pump hot water price or cost, while Victorian programmes can add a dedicated heat pump hot water rebate or solar hot water rebate on top. There are also schemes that support an electric hot water system rebate when you switch from gas to an efficient electric option. Together, these hot water rebate VIC incentives can slash the installed cost of a solar hot water system or heat pump by a substantial percentage.
When you factor in rebates plus bill savings of hundreds of dollars per year, payback periods on a quality solar hot water installation or heat pump hot water installation in Berwick can be cut to just a few years, especially if you run the system on off-peak tariffs or use timers and solar diversion to soak up excess rooftop solar. Smart controls make it even easier to get the most from an energy efficient hot water system without changing your daily routine.
If your current unit is more than 10 years old, running out of hot water or needing regular hot water repair, it is a good time to compare heat pump vs solar hot water and solar hot water vs electric hot water for your Berwick home. Whether you are dealing with solar hot water repair, planning a solar hot water tank replacement or looking to move from gas to an all-electric hot water upgrade, working with experienced local hot water installers matters. Berwick’s strong solar resource and growing focus on sustainability mean there has never been a better time to cut bills, reduce emissions and improve comfort with a modern hot water system.
