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 Denison and the 3858 area, 225 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 Denison's climate delivering an average of 4.2 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 - Denison
Based on the Australian Bureau of Statistics 2021 Census (ABS), Denison has around 1,361 private dwellings, home to approximately 2,713 people. With an average household size of 2.4 people, and around 50 litres of hot water used per person each day in Australia, Denison 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 Denison's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Denison community is home to 198 couple families with children and 54 one-parent families, meaning a large proportion of households face substantial hot water demand. With 386 homes owned with a mortgage and 501 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.
Denison is converting hot water demand to efficient systems faster than many peers, with 16.5% of dwellings already upgraded.
Hot water systems in Denison
Across Denison and the 3858 area, more households are shifting from old gas and electric units to modern, energy efficient hot water systems. With an average household size of around 2.4 people and more than 1,100 occupied dwellings, hot water is a big chunk of local energy use. Power prices keep creeping up, so upgrading your hot water system is a simple, logical step to cut bills without changing how you live.
Denison’s solar exposure is ideal for efficient hot water. The local climate data shows mean daily solar exposure of about 15.3 MJ/m² annually – roughly 4.25 kWh per square metre per day – plenty of sunshine to drive a solar hot water system or support a heat pump hot water system running on cheap daytime solar. With a median household income just under $1,200 a week and many homes owned outright or with a mortgage, an energy efficient hot water system is a smart way to protect the budget and boost comfort.
In a typical Denison home, hot water can be the second biggest energy user after heating. Many properties still run older gas or resistive electric hot water, which are far from the most efficient hot water system options available. Upgrading to a quality heat pump hot water system, solar hot water heating system or modern electric hot water system paired with rooftop solar can deliver significant annual hot water energy savings.
For Denison’s mix of three and four bedroom homes, we commonly see medium to large systems installed – enough storage for families, tradies showering twice a day, and visiting grandkids. Locally popular brands include Rheem heat pump hot water, Sanden heat pump models for ultra efficiency, and solar hot water options from Rinnai and Chromagen solar hot water. These sit alongside well known rheem solar hot water and rinnai solar hot water setups, which suit properties with good roof space and sun.
Typical bill savings from a hot water upgrade in Denison can look like this:
• Old electric to heat pump hot water installation: save around $350–$700 per year. • Gas to heat pump vs solar hot water: both can save $250–$600 per year, depending on tariffs. • Gas to solar hot water installation: save roughly 50–70% on hot water gas use. • Old electric to modern electric hot water installation with solar: save $250–$500 per year using excess solar.
Since the early 2000s, Denison has seen 225 efficient hot water installations, combining heat pump and solar hot water installation projects. Install numbers picked up around 2009–2012, with peaks of more than 20 installs a year, and have stayed steady with regular upgrades through to 2024. This trend shows growing local interest in electrification, lower running costs, and moving towards the best hot water system Australia can offer for regional homes.
When people compare heat pump vs solar hot water or solar hot water vs electric hot water, the decision usually comes down to roof space, budget, and whether there is existing solar. A heat pump hot water price / cost can be similar to a quality solar hot water price / cost once rebates are applied, and both are far more efficient than standard electric hot water vs gas hot water. For some homes, a straightforward electric hot water installation, timed to run on solar, can still be an energy efficient hot water system choice.
Hot Water Rebates, Tariffs & Savings
Around Denison VIC, interest is growing in replacing old gas or electric units with efficient options, helped along by generous hot water rebate VIC programs. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible heat pump hot water installation and solar hot water installation, effectively reducing the upfront hot water system price by hundreds of dollars. On top of that, state programs can add a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate for certain households, cutting the effective heat pump hot water price / cost or solar hot water price / cost by a substantial percentage.
For many Denison homes, combining rebates with off-peak or solar-friendly tariffs can shorten payback periods to just a few years. Smart controls, timers or solar-diversion devices can push more of your hot water heating into sunny hours, turning your system into the most efficient hot water system your roof and budget allow. If you have an older tank, a solar hot water tank replacement can often be rolled into the same project, and hot water repair or solar hot water repair can be a chance to assess whether a full upgrade makes better financial sense.
If your existing unit is more than ten years old, noisy, or struggling to keep up, now is a good time to check whether your Denison home is ready for a hot water upgrade. Whether you are moving from gas to an all-electric home, weighing up solar hot water vs electric hot water, or chasing the best heat pump hot water system, working with experienced local installers matters. Our hot water installation and hot water repair specialists understand Denison’s climate, tariffs and rebate options, and can help you choose a reliable, energy efficient hot water system that cuts bills, reduces emissions and future-proofs your property.
