The 6603 postcode, covering Lake Ninan, Konnongorring, Lake Hinds, Mocardy and Wongan Hills and surrounding areas, is home to around 543 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 Lake Ninan and the 6603 area, 130 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 Lake Ninan's climate delivering an average of 5.4 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 Lake Ninan
Around Lake Ninan, more locals are rethinking their old gas and electric hot water system and switching to energy efficient options. With mostly separate houses, an average household size of about 2.3 people and many families on a median household income of around $1,320 a week, it makes sense to cut running costs wherever you can. Hot water can be one of the biggest power users in a home, so upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical next step.
The Lake Ninan area has excellent solar exposure, with average daily sunshine of about 19.6 MJ/m² – roughly 5.4 kWh/m² per day – which is ideal for both a solar hot water heating system and high performance heat pump hot water. That strong sun means a solar hot water installation can do a lot of the heavy lifting, while a heat pump uses the mild air temperatures to deliver the most efficient hot water system performance even when it is cloudy. For households still on older storage units, the annual hot water energy savings from upgrading can easily reach hundreds of dollars a year.
In the 6603 postcode there are around 440 occupied dwellings, with a solid mix of homes owned outright and with a mortgage, plus more than 130 rented properties. That mix, and a median mortgage of about $1,083 a month, explains why people are looking for an energy efficient hot water system that keeps bills predictable. Many homes have already moved to all‑electric living with rooftop solar, so choosing between heat pump vs solar hot water or newer electric hot water vs gas hot water is now front of mind.
Across Lake Ninan and surrounds, efficient hot water systems have been steadily appearing on sheds and back verandahs. Brands like Rheem heat pump hot water and Rheem solar hot water are popular for reliability, while Rinnai solar hot water and premium Sanden heat pump units appeal to those chasing the best heat pump hot water system performance and very low running costs. Chromagen solar hot water is also seen on rural properties wanting a robust solar hot water tank replacement that can handle local conditions.
Typical annual bill savings for a Lake Ninan household are:
• Old electric to heat pump hot water system: $350–$700 per year • Gas storage to heat pump hot water installation: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water installation with rooftop solar: $200–$450 per year
These are realistic ranges and will vary with household size and how much hot water you use, but they show why locals are paying closer attention to hot water system price and long‑term cost rather than just the sticker.
Recent installs in Lake Ninan tell the story. There have been about 130 efficient hot water installations (heat pump and solar) recorded in the 6603 area. Installations started slowly in the early 2000s, then jumped around 2009–2012 as rebates and early solar hot water rebate schemes kicked in, with 13 systems in 2009 and 12 in 2010 alone. After that, numbers levelled out but have remained steady, with a noticeable lift again from 2021 onwards as energy prices rose and more people looked for the most efficient hot water system to pair with their solar. This trend shows growing local interest in electrification, lower running costs and cutting reliance on bottled or mains gas.
Hot Water Rebates, Tariffs & Savings
Across WA, including Lake Ninan, there is strong interest in replacing old gas or electric units with efficient heat pump hot water, solar hot water or modern electric hot water systems that work well with rooftop solar. Federal incentives in the form of Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost and heat pump hot water price / cost, effectively acting as a built‑in solar hot water rebate or heat pump hot water rebate at the point of sale. On top of that, WA and other state programs from time to time offer additional hot water rebate wa style support, and there are also electric hot water system rebate offers in some schemes for moving away from gas.
For a typical Lake Ninan family, these incentives can knock a substantial percentage off the system cost, bringing quality systems like Sanden heat pump or Rheem solar hot water into reach. When you add the ongoing savings – often several hundred dollars a year – the payback period can shrink dramatically, especially if you use timers or solar diversion to run your hot water system when your solar is generating. For many homes, solar hot water vs electric hot water on grid tariffs is no contest once rebates and solar exports are factored in.
If your current unit is more than 10 years old, running out of hot water, or you are still on gas, this is a good time to see if your Lake Ninan home is ready for a hot water upgrade. Whether you are weighing heat pump vs solar hot water, comparing solar hot water vs electric hot water, or just want a straight electric hot water system with better efficiency, working with experienced hot water installers and repairers matters. Local specialists can size the system correctly for your household, handle hot water installation and hot water repair, and advise on tariffs, hot water system price and ongoing costs. With Lake Ninan’s strong sun and growing focus on sustainability, efficient hot water systems can trim your bills, cut emissions and future‑proof your home.
