Hot water systems in Greenhills
Across Greenhills and the 6302 district, more homeowners are rethinking their hot water system and moving away from older gas and power‑hungry units. With average household sizes around 2.2 people and a big share of homes owned outright, many locals are at the perfect stage of life to invest in a more energy efficient hot water system that cuts bills and future‑proofs the home. Median household incomes are modest for WA, so every dollar saved on running costs really matters.
Greenhills is also blessed with strong sun. The local weather station shows mean daily solar exposure of about 19.2 MJ/m², which works out to roughly 5.3 kWh of solar energy per square metre per day over the year. That is excellent for a solar hot water system or heat pump hot water system, both of which rely on our sunshine and mild climate to deliver reliable, low‑cost hot water. Swapping from an old gas or electric hot water system to a modern heat pump or solar hot water heating system can dramatically reduce the energy used for showers, washing and cleaning — one of the biggest loads on most Greenhills power bills.
In the 6302 area there are 1,422 occupied private dwellings, mostly separate houses with three or four bedrooms, so hot water demand is steady but predictable. Hot water can easily be 20–30% of total household energy use, especially in all‑electric homes. That is why more locals are comparing heat pump vs solar hot water and even looking at solar hot water vs electric hot water when planning their next upgrade. Brands like Rheem, Rinnai, Sanden and Thermann are common choices, whether you are chasing the best hot water system Australia can offer, a premium Sanden heat pump, a rheem heat pump hot water system, or a reliable rheem solar hot water or rinnai solar hot water setup.
Typical savings in Greenhills look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year. • Gas to heat pump hot water system: save around $250–$600 per year. • Gas to solar hot water installation: save about $250–$550 per year. • Old electric to modern electric hot water installation backed by solar: save roughly $200–$450 per year.

When it comes to hot water WA incentives, there is growing interest in using rebates to bring down the hot water system price or cost. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, acting like an upfront discount. On top of that, WA hot water rebate programs and occasional electric hot water system rebate offers can further reduce the heat pump hot water price or cost or the solar hot water price or cost by a substantial percentage. For many Greenhills homes, that means payback periods of only a few years, especially if you use timers or solar diversion to run your energy efficient hot water system when rooftop solar is producing.
Whether you are looking at chromagen solar hot water, a rheem solar hot water system with a solar hot water tank replacement, a best heat pump hot water system from Sanden, or simply a solid electric hot water vs gas hot water upgrade, it pays to get local, tailored advice.
