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 Bidwill and the 4650 area, 2,984 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 Bidwill's climate delivering an average of 5.3 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 Bidwill
Across Bidwill and the wider 4650 area, more households are rethinking their hot water system and moving away from old, power‑hungry gas and electric units. With around 13,600 occupied dwellings and an average household size of 2.3 people, there is steady daily demand for reliable hot water, but also growing pressure from rising energy costs. Many locals own their homes outright or with a mortgage, so upgrading to an energy efficient hot water system is a logical next step to cut bills and future‑proof the property.
Bidwill is well suited to efficient hot water technology. The Maryborough weather station records an average annual solar exposure of about 19 MJ/m² per day, which is roughly 5.3 kWh/m² of sun each day. That strong sunshine helps a solar hot water system or heat pump hot water system run more efficiently, especially when paired with rooftop solar. For families on a median household income of around $1,035 per week, shifting from older gas or electric hot water to a modern heat pump or solar hot water heating system can deliver meaningful annual hot water energy savings without sacrificing comfort.
In the 4650 postcode, most homes are separate houses with three or four bedrooms, which typically means higher hot water demand and a bigger opportunity to save. Many households are still on traditional gas or resistive electric hot water, but the share of efficient systems is rising as people compare heat pump vs solar hot water and even modern electric hot water system options optimised to run on solar. Popular brands in the region include Rheem and Rinnai for solar hot water installation and electric hot water installation, as well as Sanden and Stiebel‑style premium heat pumps for those chasing the most efficient hot water system.
Typical annual bill savings in Bidwill can look like this:
• Old electric to a quality heat pump hot water system: $400–$800 per year • Gas hot water to heat pump: $300–$700 per year • Gas to a well‑designed solar hot water system: $250–$600 per year • Old electric to efficient electric hot water with rooftop solar: $250–$500 per year
These ranges will vary with household size, tariffs and how much solar you have, but they give a realistic guide when weighing hot water system price and long‑term running costs.
Recent installs in Bidwill and the surrounding 4650 area show how quickly things are changing. There have been 2,984 efficient hot water installations to date, combining heat pump hot water installation and solar hot water installation. Uptake grew sharply from the mid‑2000s, peaking around 2009–2010, then stabilising before another surge in 2023 with 202 new systems and strong numbers continuing into 2024 and 2025. This steady growth reflects rising interest in electrification, lower running costs, and making the most of local solar conditions with energy efficient hot water system choices such as Rheem solar hot water, Rinnai solar hot water, Chromagen solar hot water and premium units like Sanden heat pump models.
Hot Water Rebates, Tariffs & Savings
Homeowners in Bidwill are increasingly replacing old gas or tired electric units with efficient options like heat pump hot water, modern electric hot water vs gas hot water, and solar hot water vs electric hot water setups that work hand‑in‑hand with rooftop PV. Australian Government Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount off the solar hot water price or heat pump hot water price. On top of this, Queensland hot water rebate programs and energy‑efficiency schemes can provide a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some cases, trimming the hot water system cost by a substantial percentage.
For a typical Bidwill household, combining rebates with smart tariffs and timers can cut hundreds of dollars per year from bills, and the payback period on a quality system can drop to just a few years. Using timers or solar diversion to run an electric hot water system or rheem heat pump hot water during the middle of the day helps soak up excess solar and unlock even more savings. When a solar hot water tank replacement or solar hot water repair is needed, many residents take the opportunity to upgrade to the best hot water system Australia has to offer for their needs, or to the best heat pump hot water system their budget allows.
If your current unit is ageing, noisy, or your bills keep creeping up, it is a good time to check whether your Bidwill home is ready for a hot water upgrade. Whether you are considering heat pump hot water, a solar hot water repair and upgrade, or a modern electric hot water system, working with experienced hot water QLD installers who specialise in efficient systems is essential.
