The 6290 postcode, covering Deepdene, Augusta, East Augusta, Kudardup, Leeuwin and Molloy Island and surrounding areas, is home to around 1,495 households. 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 Deepdene and the 6290 area, 273 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 Deepdene's climate delivering an average of 4.7 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. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Deepdene
In Deepdene, hot water is something you notice most when it is not working. With power prices rising and many locals looking to move away from ageing gas units, more homes are switching to an energy efficient hot water system such as a heat pump hot water system, solar hot water system or modern electric hot water system. With an average household size of just 1.9 people and a big share of homes owned outright, Deepdene’s 6290 postcode is full of retirees and smaller households keen to cut running costs without sacrificing comfort.
Deepdene’s sunny coastal climate is ideal for efficient hot water. The local weather station records an average annual solar exposure of about 16.9 MJ/m² per day, which works out to roughly 4.7 kWh of solar energy per square metre each day. That is strong, consistent sunlight to drive a solar hot water heating system or support a heat pump hot water installation. With 822 occupied private dwellings and a high proportion of separate houses, there is plenty of suitable roof and yard space for a solar hot water installation, heat pump unit or solar-ready electric hot water installation as part of an all-electric home upgrade.
Across the 6290 area, hot water demand is steady rather than extreme, but it still makes up a big chunk of household energy use. Many homes are still on older gas or resistive electric units, so upgrading to the most efficient hot water system you can afford is one of the easiest ways to trim bills. Well known brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, whether you are looking at a rheem solar hot water package, a rheem heat pump hot water system, a rinnai solar hot water system, a sanden heat pump, or a straightforward electric hot water system replacement.
Typical yearly bill savings in Deepdene look like this:
• Replacing an old electric hot water system with a quality heat pump hot water system: around $350–$700 per year • Switching from gas hot water to a heat pump hot water system: around $300–$600 per year • Switching from gas to a solar hot water system: around $250–$550 per year • Upgrading an old electric to a modern electric hot water system paired with rooftop solar: around $250–$500 per year
These savings depend on your tariff, how many people live in the home and how you use hot water, but they give a realistic feel for what Deepdene households can expect. When you compare heat pump vs solar hot water, both can be part of the best hot water system Australia has to offer; the right choice depends on your roof space, budget and whether you already have solar PV. Many locals find that a high quality, best heat pump hot water system is the simplest path to an energy efficient hot water system, while others prefer a roof-mounted solar hot water vs electric hot water setup with a ground tank.
Efficient hot water has been steadily growing in Deepdene. There have already been 273 efficient hot water installations (heat pump and solar) recorded in the 6290 postcode. Installations jumped sharply around 2009, with 33 systems going in that year, then settled into a steady pattern, with 10–15 systems most years from 2017 through to 2024. Even in 2025 there are already several new systems installed. This long-term trend shows more local households are interested in electrification, lower running costs and reliable hot water repair and replacement options that do not lock them into gas for decades.
Hot Water Rebates, Tariffs & Savings
Across Western Australia, there is strong interest in replacing old gas or electric hot water with efficient options in Deepdene. Federal incentives, like Small-scale Technology Certificates (STCs), apply to eligible solar hot water systems and heat pump hot water systems, effectively acting as a solar hot water rebate or heat pump hot water rebate that reduces the upfront solar hot water price / cost or heat pump hot water price / cost. For some households, these discounts can shave thousands off the installed hot water system price / cost, especially when combined with state-based programs and occasional electric hot water system rebate offers for efficient models.
For Deepdene homeowners, that means you can often upgrade to an energy efficient hot water system with a payback period of just a few years, particularly if you already have rooftop solar and can run your electric hot water vs gas hot water on daytime solar generation. Using timers or smart controls to run a solar hot water vs electric hot water boost cycle when the sun is shining can further cut bills. Many locals also use solar-diversion devices to push excess PV into their hot water tank, turning a standard electric hot water system into a very low-cost solar hot water tank replacement option.
When it comes to brands, you will see rheem solar hot water and chromagen solar hot water on many roofs, along with rinnai solar hot water in both split and close-coupled designs. Ground-mounted heat pumps like sanden heat pump units and rheem heat pump hot water systems are popular where roof space is limited or shading is an issue. A local installer can help you weigh up solar hot water price / cost versus heat pump hot water price / cost and decide which is the most efficient hot water system for your property.
If your current unit is leaking, needs frequent hot water repair, or is more than 10–15 years old, it is worth planning a hot water upgrade before it fails completely. Choosing between solar hot water vs electric hot water, or electric hot water vs gas hot water, is not just about upfront cost; it is about running costs, comfort, emissions and future-proofing your Deepdene home.
If you live in Deepdene and your old gas or electric unit is on its last legs, now is a smart time to look at a heat pump hot water installation, solar hot water installation or efficient electric hot water installation. With strong sun, good hot water rebate WA incentives and a community that values sustainability, an efficient hot water system can cut bills, reduce emissions and add comfort.
