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 Diamond Tree and the 6258 area, 733 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 Diamond Tree's climate delivering an average of 4.6 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 Diamond Tree
Around Diamond Tree, more locals are rethinking their hot water system and moving to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With mostly separate houses (over 2,500 dwellings) and an average household size of 2.3 people, hot water demand is steady all year round, especially for families and older residents. Power prices keep creeping up, so upgrading an old gas or electric unit is a logical next step if you want lower running costs and better reliability.
Diamond Tree enjoys strong sunlight for much of the year, with average solar exposure of about 16.6 MJ/m² per day – roughly 4.6 kWh/m²/day. That is ideal for a solar hot water heating system or a high quality heat pump hot water installation that uses the ambient air efficiently, even on cooler days. For many households on a median weekly income of around $1,275, cutting hundreds of dollars a year off bills can make a real difference. Swapping out an ageing gas storage unit for an energy efficient hot water system is one of the easiest ways to do it.
In the 6258 area, most homes are separate houses with three or four bedrooms, so a family‑sized hot water installation is usually the right fit. Hot water use can be one of the biggest chunks of household energy, especially if you are still on an old electric hot water system. That is why we are seeing more interest in options like Rheem heat pump hot water, Sanden heat pump units and roof‑mounted brands such as Rheem solar hot water and Rinnai solar hot water, alongside Chromagen solar hot water on some properties. Local installers can help you compare heat pump vs solar hot water, or even solar hot water vs electric hot water if you already have rooftop solar.
Typical annual bill savings in the Diamond Tree climate look like:
• Old electric to heat pump hot water system: about $350–$700 per year • Gas storage to heat pump: about $250–$550 per year • Gas storage to solar hot water system: about $300–$600 per year • Old electric to modern electric hot water installation with solar PV: about $250–$500 per year
Efficient hot water is not just a theory here. There have already been 733 efficient hot water installations (heat pump and solar hot water installation jobs combined) recorded in the 6258 postcode. Install numbers climbed steadily from the early 2000s, peaking around 2008–2011 when 40–70 systems a year were going in, and they have continued at a steady trickle through to 2025. This shows a clear, long‑term shift towards electrification, lower running costs and the most efficient hot water system households can reasonably afford.
Hot Water Rebates, Tariffs & Savings (H2)
Across WA, including Diamond Tree, more people are replacing old gas or resistive electric units with a heat pump hot water system, newer electric hot water system or a solar hot water heating system. Federal incentives through Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water installations, effectively working like an upfront discount off the hot water system price. On top of that, WA hot water rebate programs and occasional state offers can further reduce heat pump hot water price or solar hot water price, and there may be support for an electric hot water system rebate when moving away from gas.
With the right mix of rebates, many Diamond Tree homes can cut the hot water system cost by a substantial percentage and shorten the payback period to just a few years, especially if you also run the system on daytime solar. Simple tricks like using timers or solar diversion can make an already energy efficient hot water system even cheaper to run. For those comparing electric hot water vs gas hot water, or wondering about solar hot water tank replacement versus a fresh heat pump hot water installation, local advice is invaluable.
If you live in Diamond Tree and your current unit is old, noisy or costing a fortune to run, it is a good time to check whether your home is ready for a hot water upgrade.
