Hot water systems in Wembley Downs
Across Wembley Downs, more homeowners are swapping old gas units and tired electric tanks for modern, energy efficient hot water systems. With around 9,981 dwellings and an average household size of 2.3 people, reliable hot water is non‑negotiable – but so is keeping power bills under control. Rising energy costs, solid median household incomes and a big share of mortgaged homes mean many locals are now treating a hot water upgrade as a smart, long‑term investment rather than just a grudge purchase.
The local climate makes that decision even easier. Wembley Downs enjoys strong sunshine, with mean daily solar exposure of about 19.3 MJ/m² – roughly 5.4 kWh/m² per day – which is ideal for a solar hot water system or heat pump hot water system. A well‑designed solar hot water heating system can use that free sun to cover most of your hot water needs, while a quality heat pump hot water installation can pull heat from the coastal air, even on cooler days, to deliver the most efficient hot water system for many households. For families still on older gas or resistive electric units, the potential Annual Hot Water Energy Savings from moving to an energy efficient hot water system are substantial, especially in a postcode where more than 6,300 families are juggling busy lives and high living costs.
In 6019, hot water demand is driven by thousands of three‑ and four‑bedroom homes, plus a good mix of apartments. Many properties still run gas or older electric hot water systems, so there is plenty of room for improvement. The community is steadily shifting towards all‑electric homes, pairing rooftop solar with efficient hot water. When you compare heat pump vs solar hot water, the right choice often comes down to roof space, household size and whether you already have PV. Brands like Rheem and Rinnai are popular for both solar hot water installation and electric hot water installation, while premium options like Sanden heat pump units are favoured by those chasing the best heat pump hot water system and ultra‑low running costs. Chromagen solar hot water systems are another familiar name around Perth’s western suburbs, especially for coastal homes upgrading older solar hot water tanks.
To give you a feel for savings, here are typical annual bill reductions many Wembley Downs households can see with the right hot water installation:
• Old electric hot water system to quality heat pump: save around $400–$800 per year. • Gas storage to heat pump hot water system: save roughly $250–$600 per year. • Gas storage to solar hot water system: save about $300–$700 per year. • Old electric to modern electric hot water system with good rooftop solar: save around $300–$650 per year.
Over the years, efficient hot water has quietly taken off locally. There have already been about 930 efficient hot water systems installed in Wembley Downs and the broader 6019 area, including both heat pumps and solar hot water. Installations climbed sharply from the early 2000s, peaking around 2009 with 80 installs in a single year, then settling into a steady pattern of 30–50 systems most years through the 2010s and early 2020s. That trend shows consistent interest in lower running costs, electrification and replacing ageing gas units before they fail. Recent years still show dozens of systems going in annually, as more residents hear about solar hot water vs electric hot water, compare heat pump hot water price and solar hot water price, and realise the long‑term savings.
Hot Water Rebates, Tariffs & Savings
Right now, there is growing interest in Wembley Downs in swapping out old gas or electric units for efficient options such as a heat pump hot water system, modern electric hot water system or rooftop‑assisted solar hot water system. Federal incentives, like Small‑scale Technology Certificates (STCs), effectively act as an upfront discount on eligible systems, including many rheem solar hot water, rinnai solar hot water, rheem heat pump hot water and Sanden heat pump models. On top of that, WA‑based schemes and installer discounts can function as a practical solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate in some programs, trimming the hot water system price significantly.
For Wembley Downs homeowners, these hot water rebate WA offers can cut the effective heat pump hot water cost or solar hot water cost by a meaningful percentage, often shaving thousands off premium systems. Combine that with hundreds of dollars a year off your power bills and the payback period can shrink to just a few years, especially if you already have solar and use timers or solar diversion to run the system when your panels are producing. For many, it becomes easy to justify a solar hot water tank replacement or moving to the best hot water system Australia can offer for their situation.
If your current unit is getting old, running out of hot water or costing a fortune to run, this is a good time to see whether your Wembley Downs home is ready for a hot water upgrade. Whether you are moving from gas to a heat pump, comparing solar hot water vs electric hot water, or simply planning a like‑for‑like hot water repair or solar hot water repair, working with experienced local installers is essential. With strong solar, a clear local trend towards sustainability and plenty of efficient technology on offer, upgrading your hot water WA system can cut bills, reduce emissions and future‑proof your home.
