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 Gunalda and the 4570 area, 3,138 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 Gunalda's climate delivering an average of 5.2 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 systems in Gunalda
Across Gunalda and the wider 4570 area, more households are swapping old gas and power‑hungry electric units for modern, energy efficient hot water systems. With an average household size of around 2.4 people and more than 17,000 dwellings in the postcode, reliable hot water is essential – but so is keeping running costs under control on a median household income of about $1,169 a week.
Upgrading to a modern hot water system is one of the easiest ways for Gunalda homeowners to cut bills. The local climate does a lot of the heavy lifting: the Gunalda Post Office weather station records about 18.8 MJ/m² of solar exposure annually – roughly 5.2 kWh/m² per day – which is excellent for both a solar hot water system and a heat pump hot water system. That strong sunshine helps a solar hot water heating system produce more of your hot water for free, and boosts the efficiency of heat pump hot water, especially when paired with rooftop solar.
Many homes in Gunalda are older separate houses, often still running gas or ageing electric hot water. Replacing these with an energy efficient hot water system can deliver substantial Annual Hot Water Energy Savings – often hundreds of dollars a year – while making it easier for families and retirees (a big share of the local population is over 55) to manage cost of living.
In the 4570 area, we are seeing steady growth in efficient hot water, particularly heat pump hot water installation on existing homes and solar hot water installation on properties that already have PV. Brands like Rheem heat pump hot water and Sanden heat pump units are popular for low running costs, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water systems suit homes with good roof space. For many households, these are among the best hot water system Australia options when you factor in rebates and local conditions.
Average annual bill savings will vary, but typical ranges for Gunalda homes look like:
• Old electric hot water system to 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 hot water to modern electric hot water system with solar: $250–$600 per year
With 3,138 efficient hot water installations already recorded in the postcode, Gunalda is clearly part of the shift to all‑electric, low‑running‑cost homes. Installations ramped up from only a few dozen systems per year in the early 2000s to peaks around 2007–2010 and again in 2019, with strong numbers continuing through 2023 and 2024. That trend shows growing interest in electrification, lower bills and the most efficient hot water system choices, especially as more roofs fill with solar.
Even if you are simply comparing electric hot water vs gas hot water, it makes sense in Gunalda QLD to look at options that work with solar. A well‑sized electric hot water system on a timer, or a solar hot water vs electric hot water setup with diversion, can dramatically reduce grid energy use. When an older solar hot water tank replacement is due, many locals now compare heat pump vs solar hot water carefully, weighing heat pump hot water price / cost, solar hot water price / cost and long‑term savings.
There is also strong support from government. Gunalda homeowners can usually access Small‑scale Technology Certificates (STCs) on eligible systems, which act like a solar hot water rebate or heat pump hot water rebate and cut the upfront hot water system price / cost. On top of that, Queensland hot water rebate QLD programs and electric hot water system rebate offers periodically reduce the cost of approved systems even further. These discounts can effectively shave a large percentage off the system cost, shorten payback times and help upgrades pay for themselves in just a few years. Using timers or solar‑diversion controls can further improve savings by heating water when your panels are producing.
If your current unit is old, unreliable or running on gas, now is a smart time to see if your Gunalda home is ready for a hot water upgrade. Whether you are considering a heat pump hot water system, a solar hot water system or a high‑efficiency electric hot water installation, working with experienced local hot water installers is the best way to get the right solution for your roof, budget and lifestyle.
