Hot Water Systems in Lagrange
The 6725 postcode, covering Lagrange, Bilingurr, Broome, Dampier Peninsula, Djugun, Eighty Mile Beach, Gingerah, Minyirr, Roebuck and Waterbank and surrounding areas, is home to around 3,986 households. With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
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 Lagrange and the 6725 area, 1,358 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 Lagrange's climate delivering an average of 6.3 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.

Community Hot Water Statistics - Lagrange, 6725
Hot Water Demographics - Lagrange
Based on the Australian Bureau of Statistics 2021 Census (ABS), Lagrange has around 3,986 private dwellings, home to approximately 9,637 people. With an average household size of 2.7 people, and around 50 litres of hot water used per person each day in Australia, Lagrange households use approximately 135 litres of hot water daily, equating to a massive 0.5 million litres of hot water used across the suburb every single day.
Other census insights reinforce Lagrange's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Lagrange community is home to 909 couple families with children and 338 one-parent families, meaning a large proportion of households face substantial hot water demand. With 870 homes owned with a mortgage and 445 owned outright, many residents also have the homeownership and growing equity that make switching to efficient hot water systems a practical way to lower expenses.
Lagrange is converting hot water demand to efficient systems faster than many peers, with 34.1% of dwellings already upgraded.
Hot water systems in Lagrange
Around Lagrange, more households and local businesses are rethinking how they heat their water. With power prices rising and a warm West Kimberley climate, shifting from old gas or ageing electric units to an energy efficient hot water system simply makes sense. Families here typically have around 2.7 people per household, and with more than 3,300 dwellings across the 6725 area, hot water demand adds up fast. For many homes juggling a median mortgage of about $2,167 a month or rent around $260 a week, long‑term savings from a better hot water system are worth a close look.
Lagrange is blessed with serious sunshine. The local weather station at Bidyadanga records an average annual solar exposure of about 22.6 MJ/m² per day, which is roughly 6.3 kWh of solar energy per square metre every day. That strong sun is ideal for a solar hot water system or a modern heat pump hot water system that uses the warm air to heat water efficiently. When you compare heat pump vs solar hot water in this climate, both options perform well, especially when paired with rooftop solar. Upgrading from an older gas storage unit or a power‑hungry electric hot water system can deliver substantial annual hot water energy savings for Lagrange households.
Across the 6725 postcode there are 2,593 separate houses and hundreds of townhouses and units, many of them family homes. That means morning showers, evening baths and constant laundry all drive hot water demand. A well‑sized solar hot water heating system or high‑quality heat pump can cover most of this usage with far less energy than a traditional system. Brands like Rheem and Rinnai are common choices for reliable solar hot water installation and electric hot water installation, while Sanden and Thermann are popular for premium, ultra‑efficient heat pump hot water installation options.
Typical savings from upgrading in a sunny WA town like Lagrange can look like:
• Replacing an old electric hot water system with a heat pump hot water system: save around $400–$800 per year on bills. • Switching from gas to a heat pump hot water system: save roughly $300–$700 per year, depending on gas tariffs. • Moving from gas to a solar hot water system: save around $300–$600 per year. • Upgrading an old electric unit to a modern electric hot water system running on your rooftop solar: save about $250–$500 per year.
Over time, these savings help offset the hot water system price or cost. A quality heat pump hot water price or cost will usually be higher upfront than a basic electric unit, but the running costs are much lower. Similarly, a solar hot water price or cost is higher at installation, yet the free energy from the sun quickly narrows the gap. For many homes, the most efficient hot water system is either a well‑matched heat pump or a solar hot water vs electric hot water setup that uses your solar panels and a smart timer to heat water during the day.
In Lagrange and the broader 6725 area, there have already been 1,358 efficient hot water systems installed, including both heat pump and solar hot water systems. Installations ramped up strongly between 2007 and 2013, peaking around 2011 with 188 hot water installations in a single year. While numbers have eased in recent years, there is a steady trickle of new systems each year from 2019 through to 2025, showing ongoing interest in electrification, lower running costs and more sustainable hot water WA‑wide. This local experience also means there is a solid base of know‑how for hot water repair, solar hot water repair and solar hot water tank replacement when older systems reach the end of their life.
When it comes to hot water rebate WA programs, Lagrange households can tap into a mix of federal and state incentives. The national Small‑scale Technology Certificates (STCs) scheme lowers the effective solar hot water price or cost and heat pump hot water price or cost at the point of sale. On top of that, state and retailer energy efficiency schemes may offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate for approved models. These hot water rebate WA incentives can slice a substantial percentage off the upfront cost, sometimes turning a premium system into a very affordable upgrade. Combine that with hundreds of dollars a year in bill savings, and the payback period for an energy efficient hot water system can shrink to just a few years, especially if you use timers or solar diversion to maximise daytime heating.
Whether you are comparing electric hot water vs gas hot water, looking at rheem solar hot water, rinnai solar hot water, rheem heat pump hot water, sanden heat pump options or even chromagen solar hot water, the key is matching the system to your household size, roof space and budget. For many, the best hot water system Australia‑wide in a hot, sunny climate is a high‑efficiency heat pump or solar unit backed by good local support. Others may prefer a robust modern electric hot water system paired with rooftop solar as a stepping stone away from gas.
If your current unit is older, unreliable or driving up bills, it is a good time to check whether your Lagrange home or business is ready for a hot water upgrade. An experienced local team can help you weigh up heat pump vs solar hot water, assess the best heat pump hot water system options for your needs, and advise on hot water installation, hot water repair and available rebates. With strong solar exposure, growing interest in sustainability and plenty of detached homes, Lagrange is well‑placed to benefit from efficient hot water systems that cut emissions, trim bills and future‑proof your property.
