Hot water systems in Nunile
In Nunile, more locals are rethinking their old gas and electric hot water system and switching to smarter options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an older population, smaller average household size of around 2.2 people, and median household income of about $1,190 a week, running costs really matter. Upgrading to an energy efficient hot water system can be one of the easiest ways for Nunile homeowners to cut bills without sacrificing comfort.
Nunile’s sunshine is a big advantage. The area sees an average annual solar exposure of about 19.4 MJ/m² per day, which works out to roughly 5.4 kWh/m² of solar energy every day across the year. That strong sun helps a solar hot water heating system perform well, and also boosts the efficiency of a heat pump hot water system, especially when paired with rooftop solar. With most of the 1,291 occupied dwellings being separate houses, there is plenty of roof space and yard room for solar hot water installation or a larger heat pump hot water installation. For many homes, shifting from older gas or resistive electric units to efficient hot water technology can deliver substantial annual hot water energy savings.
Around postcode 6566, hot water demand is steady rather than extreme, thanks to smaller households and a higher proportion of older residents, but hot water still makes up a big share of total energy use. Many homes are now combining rooftop solar with efficient hot water, choosing brands like Rheem and Rinnai for solar hot water vs electric hot water upgrades, or looking at premium heat pump units such as Sanden and Reclaim-style systems when comparing the best heat pump hot water system options in Australia. When people ask about the best hot water system Australia wide, they are usually weighing up heat pump vs solar hot water for the most efficient hot water system their budget allows.
Typical annual bill savings in Nunile look like this:
• Replacing an old electric hot water system with a quality heat pump: save roughly $350–$700 per year. • Swapping gas hot water for a heat pump hot water system: save around $250–$600 per year. • Changing gas to a solar hot water system: save about $250–$550 per year. • Replacing a very old electric unit with a modern electric hot water system and using rooftop solar: save roughly $200–$450 per year.

Hot Water Rebates, Tariffs & Savings
Across Nunile WA, there is strong interest in replacing old gas or electric hot water with efficient options like heat pumps, solar hot water and modern electric units. Homeowners can often access a mix of Australian Government incentives and state hot water rebate WA programmes. Small-scale Technology Certificates (STCs) effectively act as an upfront discount on eligible solar hot water installation and heat pump hot water installation, cutting the solar hot water price / cost or heat pump hot water price / cost by a meaningful amount. On top of this, WA schemes and retailer offers may support a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate for certain households.
