With an average household size of around 2.2 people and a big share of homes owned outright or with a mortgage, many residents are in a good position to plan a smart hot water upgrade that cuts bills without sacrificing comfort.

Arrowsmith enjoys serious sunshine. The local Green Grove weather station records mean daily solar exposure of about 20.2 MJ/m², which works out to roughly 5.6 kWh of solar energy per square metre per day across the year. That strong solar resource makes a solar hot water heating system or a high‑efficiency heat pump hot water system a logical step, especially as electricity prices rise and more families on modest median household incomes look for long‑term savings. Swapping an older gas or resistive electric unit for an energy efficient hot water system can deliver substantial Annual Hot Water Energy Savings for typical Arrowsmith households.

Across the 6525 postcode there are about 1,437 occupied private dwellings, most of them separate houses, and hot water is one of the biggest energy users in these homes. With a median age of 53 and many over‑65s, reliability and low running costs matter just as much as upfront hot water system price or cost. That is where quality brands like Rheem, Rinnai, Sanden and Thermann come in, offering options from rheem solar hot water and rheem heat pump hot water, through to rinnai solar hot water and premium sanden heat pump units that are often rated among the best heat pump hot water system choices in Australia.

In the 6525 area there have already been 729 efficient hot water installations, combining heat pump hot water installation and solar hot water installation. Install numbers climbed steadily through the 2000s, peaking around 2009–2013 when annual installs regularly sat between about 38 and 60 systems per year, and they have continued at a solid pace into the 2020s. This steady stream of hot water installation work shows growing local interest in electrification, lower running costs and moving towards the most efficient hot water system options as older units reach the end of their life.

When you compare heat pump vs solar hot water, both can dramatically reduce energy use compared with electric hot water vs gas hot water. A typical Arrowsmith home upgrading from an old electric hot water system to a modern heat pump or solar hot water system might see:

• Old electric to heat pump: around $350–$700 per year off bills. • Gas storage to heat pump: around $250–$600 per year. • Gas storage to solar hot water: around $200–$550 per year. • Old electric to modern electric hot water with rooftop solar: around $200–$500 per year.

Actual savings depend on the hot water system price or cost, household size and how much hot water you use, but in a sunny climate like hot water WA regions enjoy, the numbers can be very compelling. Many locals find that a well‑sized solar hot water vs electric hot water upgrade, or a best heat pump hot water system paired with rooftop solar, quickly becomes the most efficient hot water system option for their property.
