Upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a simple way to rein in running costs without changing your lifestyle.
Griffin’s sunshine is a big part of the story. The nearby Mango Hill weather station records mean daily solar exposure of about 19.1 MJ/m², which works out to roughly 5.3 kWh/m² per day. That strong solar resource helps a solar hot water heating system and high‑quality heat pump hot water perform efficiently all year round, even through a South East Queensland winter. When you combine that with rising electricity and gas prices, it is no surprise more homeowners are asking about heat pump vs solar hot water, solar hot water vs electric hot water and the most efficient hot water system options for their home.
In Griffin, most homes are separate houses with three or four bedrooms, so a family‑sized hot water system is usually the norm. Many properties already have rooftop solar, which pairs brilliantly with a heat pump hot water installation or modern electric hot water installation using timers or smart controls to run when your solar is producing. Brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water are increasingly common, giving homeowners reliable, energy efficient hot water system choices at different hot water system price points.
To give you a feel for savings, here are typical annual bill reductions when you upgrade in Griffin:
• Old electric to heat pump hot water system: save roughly $400–$800 per year • Gas to heat pump hot water: save around $300–$700 per year • Gas to solar hot water system: save about $250–$600 per year • Old electric to modern electric hot water with solar: save roughly $200–$500 per year
Over time, those savings can more than cover the heat pump hot water price or solar hot water price, especially when your installer helps you tap into rebates and incentives.
Efficient hot water is not new to Griffin. There have already been 1,683 efficient hot water installations – mainly heat pump and solar hot water installation projects – recorded in the 4503 postcode. Installations ramped up strongly from the mid‑2000s, peaking around 2011 with 178 systems in a single year. While annual numbers have eased back to a steadier level (around 30–40 installs a year since 2020), that long‑term trend shows a clear, sustained interest in electrification, lower running costs and cleaner hot water across the suburb. As older systems reach the end of their life, many are now being replaced with the best heat pump hot water system or a quality rheem solar hot water or rinnai solar hot water setup rather than like‑for‑like gas.
Hot Water Rebates, Tariffs & Savings
For Griffin homeowners considering a hot water upgrade, rebates and tariffs can make a big difference to the overall hot water system cost. The Australian Government’s Small‑scale Technology Certificates (STCs) reduce upfront prices for eligible solar hot water heating system and heat pump hot water installation jobs, effectively acting as a point‑of‑sale discount. On top of that, Queensland hot water rebate programs and state‑based incentives can apply to certain heat pump and electric hot water system rebate offers, further trimming the heat pump hot water price or electric hot water system cost. When you stack STCs with a state heat pump hot water rebate or solar hot water rebate, it is common to see the installed solar hot water price or heat pump cost cut by 20–40%, with payback periods dropping to just a few years. Add smart use of off‑peak tariffs, timers or solar‑diversion and many Griffin households comfortably save hundreds of dollars per year on bills. For some, shifting from electric hot water vs gas hot water to a fully electric, solar‑powered setup is the final step towards an all‑electric home.
