Hot water systems in Deanside
In Deanside, hot water is a big part of everyday comfort, and more locals are shifting to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With most of the 5,104 dwellings being separate houses and an average household size of 3.4 people, hot water demand is high. Many families are paying sizeable mortgages and energy bills, so upgrading an older gas or electric hot water system to something more efficient is a logical way to free up cashflow.
Deanside enjoys strong sunlight for Victoria, with mean daily solar exposure of about 15.10 MJ/m², or roughly 4.2 kWh/m² per day across the year. That level of solar makes both a solar hot water heating system and a heat pump hot water system perform well, especially when paired with rooftop solar. With a young median age of 31 and a high share of homes owned with a mortgage, there is strong interest in future‑proofing homes, cutting emissions and choosing the most efficient hot water system rather than sticking with old gas units.
Across 3336, thousands of efficient hot water systems have already gone in. Many new builds are choosing an all‑electric hot water upgrade from day one, while existing homes are replacing tired storage tanks with heat pumps or a solar hot water installation. A typical family here might use around a quarter of their household energy just on hot water, so the right hot water installation can make a real dent in bills. Brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water are all common choices for people comparing the best heat pump hot water system and the best hot water system Australia offers for long‑term savings.
For a rough guide, annual bill savings in Deanside often look like this:
• Old electric to heat pump hot water installation: save around $400–$800 per year. • Gas to heat pump vs solar hot water: save roughly $300–$700 per year depending on tariffs. • Gas to solar hot water system: save about $250–$600 per year. • Old electric to modern electric hot water installation with solar: save about $300–$700 per year.
Since 2016, Deanside has seen 4,641 efficient hot water installations, with numbers jumping from just 1 in 2016 to 691 in 2021 and peaking at 852 in 2022. Even in 2023 and 2024, with 749 and 665 systems installed, interest has stayed strong. This steady growth in heat pump and solar hot water repair and replacement shows how quickly locals are embracing electrification, lower running costs and quieter, more reliable systems compared with older gas hot water.
Hot Water Rebates, Tariffs & Savings
For hot water VIC households, rebates and tariffs are a big part of the story. Many Deanside homeowners are replacing old gas or electric units with a heat pump hot water system, a high‑efficiency electric hot water system or a solar hot water system to cut bills and move away from gas. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump units, effectively lowering the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, state‑based schemes can add a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate, so the final hot water system price / cost can be reduced by a substantial percentage.
For many Deanside households, combining rebates with rooftop solar and smart controls, such as timers or solar‑diversion, can cut payback periods dramatically. It is common to see hundreds of dollars per year shaved off bills, especially when switching from solar hot water vs electric hot water on peak tariffs, or from electric hot water vs gas hot water to a high‑performance heat pump. When a solar hot water tank replacement is done at the same time as a broader hot water repair or upgrade, the result is often a more energy efficient hot water system that runs mostly on free solar.
If you live in Deanside and your current system is ageing, undersized or running on expensive gas, this is a smart time to check if your home is ready for a hot water upgrade. Whether you are comparing heat pump vs solar hot water, looking at rheem solar hot water or rinnai solar hot water, or weighing up a sanden heat pump against other options, working with experienced hot water VIC installers matters. Local specialists who understand hot water rebate VIC programs, tariffs and Deanside’s strong solar exposure can help you choose the most efficient hot water system for your family, reduce bills, cut emissions and future‑proof your home—connect with trusted local experts for personalised advice with us.
