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 Coogee and the 6166 area, 705 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 Coogee'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.

Hot water systems in Coogee
In Coogee, hot water is something you notice most when it is not working. Around 3,800 dwellings and an average household size of 2.6 people means a lot of showers, dishwashers and laundry loads every day, so choosing the right hot water system really matters. With energy costs rising and many locals paying sizeable mortgages and rents, more homeowners are swapping old gas or electric units for an energy efficient hot water system such as a heat pump hot water system, solar hot water system or modern electric hot water system.
Coogee is especially well suited to efficient hot water upgrades. At nearby Woodmans Point, the average annual solar exposure is about 19.3 MJ/m² per day – roughly 5.4 kWh/m² of sunshine – which is excellent for a solar hot water heating system and also helps a heat pump hot water system run more efficiently. With strong rates of home ownership (over 3,200 homes owned outright or with a mortgage) and plenty of family households, upgrading from older gas hot water to a modern hot water system is a logical next step. Many Coogee households are already seeing solid annual hot water energy savings after moving away from ageing gas or resistive electric units.
Local hot water demand is driven by a big share of three and four bedroom homes, so storage size and running costs really count. Efficient hot water systems installed in 6166 now number around 705 heat pump and solar hot water installations, and that figure has grown steadily since the early 2000s. Coogee homeowners are increasingly comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to work out the most efficient hot water system for their roof space, budget and family size. Well known brands such as Rheem, Rinnai, Sanden and Thermann are common locally, whether you are looking at rheem solar hot water, rheem heat pump hot water, rinnai solar hot water or a premium sanden heat pump for maximum efficiency.
Typical annual bill savings for Coogee homes can look like this:
• Replacing an old electric hot water system with a heat pump hot water system: $400–$800 per year • Switching gas hot water to a heat pump hot water system: $300–$600 per year • Switching gas to a solar hot water system: $250–$550 per year • Upgrading an old electric unit to a modern electric hot water system with rooftop solar: $250–$500 per year
Recent installs in Coogee show how quickly things are shifting. From just a handful of systems each year in the early 2000s, installations jumped around 2008–2014 and have stayed solid, with 705 efficient hot water systems now in place across the postcode. Yearly data shows consistent heat pump hot water installation and solar hot water installation activity right through to 2025, reflecting strong local interest in electrification, lower running costs and cutting emissions. Many of these homes also use solar PV, so hot water installation has been timed to make the most of daytime solar generation.
Hot Water Rebates, Tariffs & Savings
Across WA, more Coogee homeowners are replacing old gas or electric hot water with efficient options like heat pumps, new electric hot water installation paired with solar, or a roof-mounted solar hot water installation. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump units, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate. On top of that, state-based schemes and occasional electric hot water system rebate offers in wa can further reduce the hot water system price or cost. For many Coogee households, these hot water rebate wa programs can trim the heat pump hot water price or cost, or the solar hot water price or cost, by a meaningful percentage and cut payback times to just a few years.
