Hot water systems in East Rockingham
In East Rockingham, more locals are swapping old gas and ageing electric units for modern, energy efficient hot water systems. With around 10,000 occupied dwellings across 6168 and an average household size of 2.1 people, a reliable hot water system is essential, but so is keeping running costs under control. Power prices and a median household income of about $1,176 a week mean many homeowners are now looking closely at a heat pump hot water system, a solar hot water system or a high efficiency electric hot water system as a smart next step.
The local climate is ideal for efficient hot water. Rockingham’s mean daily solar exposure sits at about 19.2 MJ/m², which is roughly 5.3 kWh of sunshine per square metre each day over the year. That strong solar resource supports both a solar hot water heating system on the roof and a quality heat pump hot water installation that draws warmth from the air. For many East Rockingham households, hot water can be one of the biggest energy users, so upgrading from an older gas or off‑peak tank can deliver substantial annual hot water energy savings while improving comfort.
Across postcode 6168 there is a mix of separate houses and units, with more than 3,000 homes owned with a mortgage and a similar number owned outright. That stable base of owner‑occupiers is driving demand for long‑term savings and the most efficient hot water system they can reasonably afford. A modern solar hot water system or best heat pump hot water system, paired with existing rooftop solar, can dramatically cut bills, while a new electric hot water installation can still be a solid option when sized correctly and timed to run on solar.
On the ground, we see a healthy mix of brands in East Rockingham. Rheem solar hot water and Rheem heat pump hot water units are popular with families wanting proven reliability, while Rinnai solar hot water and Chromagen solar hot water systems suit many coastal homes looking for strong performance in WA conditions. For those chasing ultra‑low running costs, a premium Sanden heat pump is often shortlisted when people research the best hot water system Australia can offer for efficiency.
To give you a feel for the savings, here are typical annual bill reductions many East Rockingham households see when they upgrade:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water: $300–$700 per year • Gas to solar hot water system: $250–$600 per year • Old electric to modern electric hot water with rooftop solar: $200–$500 per year
These figures will vary with usage and tariffs, but they show why heat pump vs solar hot water is such a common conversation locally, and why solar hot water vs electric hot water is now about long‑term value rather than just upfront hot water system price or cost.
Recent data shows 2,334 efficient hot water systems have already been installed across 6168, combining both heat pump and solar hot water installation numbers. Installations grew steadily from the early 2000s, peaking around 2009–2011 as rebates ramped up, and have remained consistent in recent years with 50–80 systems going in annually. This steady trend reflects strong local interest in electrification, lower running costs and moving away from gas hot water where practical. It also means there is now a good base of local experience in solar hot water repair, heat pump hot water repair and solar hot water tank replacement when older systems reach the end of their life.
Hot Water Rebates, Tariffs & Savings
In WA, more East Rockingham homeowners are now weighing up electric hot water vs gas hot water and choosing efficient options like heat pump hot water or a solar hot water heating system.

On top of that, WA hot water rebate programs and occasional state‑based schemes can act as a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate, trimming hundreds of dollars off the installed price and shortening the payback period.
For many households, combining rebates with rooftop solar can cut the effective system cost by a substantial percentage and deliver savings of hundreds of dollars per year on bills. Using timers or smart controls to run an energy efficient hot water system during solar hours can further improve returns. When you look at solar hot water vs electric hot water or compare the best heat pump hot water system options, it is worth considering not just the sticker price but the total lifetime cost after incentives and ongoing energy savings.
