Hot water systems in Brentwood
Across Brentwood and the wider 6153 area, more households are swapping old gas and ageing electric units for an energy efficient hot water system that is cheaper to run and kinder to the environment. With an average household size of around 2.5 people and more than 8,000 occupied dwellings in the postcode, reliable hot water is a daily essential – but rising energy costs are pushing many owners to look seriously at a modern heat pump hot water system, solar hot water system or efficient electric hot water system.
Brentwood is well suited to efficient hot water upgrades. Local solar exposure from the Melville weather station averages about 19.2 MJ/m² per day – roughly 5.3 kWh/m² of sunshine – which is excellent for both a solar hot water heating system and for supporting a heat pump hot water system that draws most of its energy from the air. With a high proportion of homes owned outright or with a mortgage and solid median household incomes, upgrading from older gas or resistive electric hot water to a more efficient hot water system is a logical next step. Over the life of the unit, Annual Hot Water Energy Savings can add up to thousands of dollars for Brentwood homeowners.
In 6153, demand for hot water installation and hot water repair is driven by a mix of family homes and downsizers. Many three and four bedroom houses still run on older gas hot water, while apartments and townhouses often use small electric storage units. Hot water typically accounts for 20–30% of a home’s energy use, so shifting to the most efficient hot water system you can reasonably afford – whether that is a quality heat pump, a roof-mounted solar hot water system, or a well-sized electric hot water system paired with rooftop solar – makes a noticeable dent in bills. Brands like Rheem heat pump hot water, Sanden heat pump units and solar hot water options from Rinnai and Chromagen solar hot water are all common choices for efficient upgrades in established suburbs like Brentwood, offering a balance of performance, warranty support and parts availability.
For a typical Brentwood home, realistic annual bill savings from a smart upgrade look like this:
• Old electric to heat pump hot water system: roughly $400–$800 per year • Gas storage to heat pump hot water system: roughly $300–$600 per year • Gas storage to solar hot water system: roughly $250–$550 per year • Old electric to modern electric hot water system with rooftop solar: roughly $250–$500 per year
These savings depend on how much hot water you use, tariffs, whether you run timers or solar diversion, and the exact hot water system price / cost at installation. When comparing heat pump vs solar hot water, many Brentwood homes with good north or west roof space lean towards a solar hot water installation, while shaded blocks or apartments often favour a compact heat pump hot water installation in the side yard. If you already have PV, a well-timed electric hot water installation can also make sense, especially when you compare solar hot water vs electric hot water run on cheap daytime solar.
Recent data shows 1,017 efficient hot water systems – mainly heat pump and solar hot water installations – have already been installed across the 6153 postcode. Installations ramped up sharply around 2008–2010, with peaks of 77 and 84 systems per year as rebates kicked in, and have since settled into a steady pattern of 20–40 installs annually through to 2025. This trend reflects a growing local interest in electrification, lower running costs and moving away from gas hot water in Brentwood, as owners replace failing units or plan renovations. Solar hot water tank replacement jobs are increasingly being upgraded to more efficient models rather than like-for-like swaps, and many residents now ask specifically for the best heat pump hot water system or the best hot water system Australia can offer for their budget.
Even if you are only just starting to think about it, there is a clear shift in Brentwood, WA towards replacing old gas or power-hungry cylinders with a more energy efficient hot water system. Federal incentives in the form of Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively reducing the upfront solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, WA homeowners can often access additional solar hot water rebate or heat pump hot water rebate support through installer-partner programs, and there are offers in some cases for an electric hot water system rebate when switching away from gas. These discounts can cut the installed solar hot water price / cost or heat pump cost by a substantial percentage, and when you combine rebates with rooftop solar and smart controls like timers or solar-diversion, payback periods can drop to just a few years. For many Brentwood households, that means hundreds of dollars per year off bills while also slashing emissions. When you factor in electric hot water vs gas hot water tariffs and the long-term trend towards all-electric homes, hot water WA upgrades are looking more attractive than ever. A well-chosen system – whether it is Rheem solar hot water, Rinnai solar hot water, a Sanden heat pump or a Chromagen solar hot water package – can give you reliable hot water repair support, strong warranties and long-term savings.
If your existing unit is more than 10 years old, running out of hot water, or costing a small fortune to run, now is a smart time to see if your Brentwood home is ready for a hot water upgrade.
