Hot water systems in Subiaco

Across Subiaco, more homeowners and businesses are swapping old gas and ageing electric units for an energy efficient hot water system that keeps bills down without sacrificing comfort. With an average household size of around 2.2 people and more than 7,700 dwellings in the 6008 postcode, there is steady hot water demand from busy professionals, young families and downsizers alike. Rising energy costs and strong local incomes mean many Subiaco households are now looking at a modern heat pump hot water system, a solar hot water system or a high‑efficiency electric hot water system as a smart next step. Subiaco’s excellent sunshine helps too – the nearby Floreat Park weather station records about 19.3 MJ/m² of solar exposure a day on average, roughly 5.4 kWh/m², which is ideal for a solar hot water heating system or a well‑set‑up heat pump.

With more than 2,100 homes owned outright and another 1,700 with a mortgage, a large share of Subiaco residents are in a good position to invest in long‑term savings. Families and owner‑occupiers are increasingly comparing heat pump vs solar hot water, or weighing up solar hot water vs electric hot water, to find the most efficient hot water system for their property. Annual hot water energy savings can be significant when you upgrade from older gas or resistive electric units to an energy efficient hot water system that works with rooftop solar and off‑peak tariffs.

In 6008, hot water energy use is a noticeable slice of the power bill for many households, especially in larger separate houses with three or more bedrooms. That is why interest in efficient hot water is growing alongside rooftop solar. Brands like Rheem and Rinnai are common choices locally, with options ranging from rheem solar hot water and rheem heat pump hot water through to rinnai solar hot water for homes wanting to cut gas use. Premium systems such as the Sanden heat pump are popular with sustainability‑minded owners chasing the best heat pump hot water system, while Chromagen solar hot water is another recognised name for those wanting a reliable solar hot water tank replacement.

Typical savings for Subiaco homes moving to efficient hot water look like:

Installations began to climb in the late 2000s, peaking around 2009–2010 with over 100 installs across those two years as early adopters jumped on generous incentives. After a quieter period, recent years such as 2017, 2019, 2021 and 2024 have all seen solid numbers, reflecting renewed interest in electrification, lower running costs and moving away from gas hot water in Subiaco. Each new hot water installation or hot water repair that upgrades an older unit helps build local experience and confidence in these technologies.

Hot Water Rebates, Tariffs & Savings

Subiaco homeowners are increasingly aware that sticking with old gas or a tired electric hot water system can be a false economy. Efficient options like a quality heat pump hot water system, a modern electric hot water system paired with rooftop solar, or a well‑designed solar hot water system can all tap into generous incentives. At the federal level, Small‑scale Technology Certificates (STCs) effectively provide an upfront discount on eligible systems, lowering the heat pump hot water price or solar hot water price at the point of sale. In WA, additional hot water rebate wa programs may apply from time to time for efficient units, including a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate when replacing old gas.

Once installed, an energy efficient hot water system can trim hundreds of dollars a year from bills, especially when you use timers or solar diversion to heat water during the middle of the day. That means the real hot water system price or heat pump hot water cost over its lifetime can be far lower than it first appears, and payback periods are often cut dramatically when you combine rebates with good solar design and smart tariffs. For many households in Subiaco, the best hot water system Australia can offer is one that works with rooftop solar, avoids volatile gas prices and delivers reliable hot water wa‑wide.

If your current unit is more than 10 years old, running on gas or costing a fortune to run, now is a good time to see whether a solar hot water repair, solar hot water tank replacement, heat pump upgrade or new electric hot water installation makes the most sense.
