Hot water systems in Derrimut
Across Derrimut, more households are switching to an energy efficient hot water system – whether that’s a modern heat pump hot water system, a solar hot water system or a well‑sized electric hot water system that works with rooftop solar. With an average household size of 3.5 people and a young median age of 32, hot water demand is high, so it makes sense to move away from older gas or power‑hungry cylinders to something that keeps bills under control.
Derrimut’s strong sunlight helps too. The local Burnside weather station records around 15 MJ/m² of solar exposure a day on average – roughly 4.2 kWh/m² – which is excellent for a solar hot water heating system and also boosts the efficiency of a heat pump hot water system. In a suburb with more than 2,300 occupied dwellings and a big share of families with kids, upgrading from an old gas or electric unit can deliver meaningful Annual Hot Water Energy Savings, often hundreds of dollars a year.
Most homes here are separate houses, with many owned with a mortgage, so long‑term running costs really matter. A well‑chosen energy efficient hot water system can ease pressure on those typical $1,976 per month mortgage repayments by trimming electricity or gas spend. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, whether you are looking at rheem solar hot water, rheem heat pump hot water, rinnai solar hot water or a premium sanden heat pump for maximum efficiency.
In postcode 3026 there have been 33 efficient hot water installations recorded – mainly heat pump hot water installation and solar hot water installation. After only the odd system going in before 2017, things picked up in 2018 and 2019, then stayed steady through 2020–2022. That steady run of new systems shows growing interest in electrification, lower running costs and getting ready for an all‑electric home in Derrimut.
For many households, the key question is heat pump vs solar hot water, or solar hot water vs electric hot water. A quality heat pump can be the most efficient hot water system for shaded roofs or townhouses, while a solar hot water system with a good solar hot water tank replacement suits sunny roofs and larger families. Modern electric hot water installation, combined with rooftop solar and timers, can also be a very energy efficient hot water system, especially when paired with an electric hot water system rebate.
Average savings will vary, but realistic annual bill reductions in Derrimut look like: • Old electric to heat pump: $350–$700 per year • Gas to heat pump: $250–$500 per year • Gas to solar hot water: $300–$600 per year • Old electric to modern electric with solar: $200–$450 per year
When you factor in the hot water system price or hot water system cost, rebates make a big difference. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump units, effectively acting as a solar hot water rebate or heat pump hot water rebate at the point of sale. Victoria also offers state incentives that can stack on top, and some systems may qualify for an electric hot water system rebate when replacing gas. Together, these discounts can slash the heat pump hot water price or solar hot water price or cost by a substantial percentage and cut payback periods to just a few years. Using timers or solar diversion to run your electric or heat pump unit during the day can further improve savings.
Of course, even the best hot water system Australia has to offer still needs proper hot water installation and ongoing hot water repair support. Local Derrimut installers can help you compare electric hot water vs gas hot water, talk through the best heat pump hot water system options, size a solar hot water heating system to your family, and arrange solar hot water repair or solar hot water tank replacement when needed.
