The nearby Steep Point weather station records around 21.5 MJ/m² of solar exposure per day on average, which works out to roughly 6 kWh/m² of solar energy daily. That strong solar resource means a solar hot water heating system or high‑efficiency heat pump can deliver big annual hot water energy savings, especially for families and older residents who are home more during the day. With 358 occupied dwellings spread across separate houses, townhouses and other dwellings, and a median age in the early 40s, there’s a mix of young families and semi‑retired couples who can all benefit from lower running costs and fewer maintenance headaches.
In the 6537 postcode, hot water demand is steady rather than massive, but it still makes up a big slice of household energy use. Many homes are still on older gas or resistive electric units, which are expensive to run in a remote WA setting. Swapping to an energy efficient hot water system – whether that’s a Sanden heat pump, Rheem heat pump hot water, Rheem solar hot water or a Rinnai solar hot water setup – can trim a large chunk off your annual electricity spend. Brands like Chromagen solar hot water are also popular where roof space and solar exposure are excellent. For many homes, a compact heat pump hot water installation paired with rooftop solar gives the most efficient hot water system option, while some prefer a roof‑mounted solar hot water installation with an electric booster.

Hot Water Rebates, Tariffs & Savings
Across WA, more Dirk Hartog homeowners are replacing old gas or basic electric units with efficient options like a heat pump hot water system, upgraded electric hot water system or a solar hot water system. Federal incentives, in the form of Small‑scale Technology Certificates (STCs), can cut the upfront solar hot water price / cost or heat pump hot water price / cost significantly. On top of that, state‑based hot water rebate WA programs may apply from time to time, including a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate that reduce the installed hot water system price / cost at the point of sale. For many households, these discounts effectively shave a substantial percentage off the system cost and can bring payback periods down to just a few years, especially when combined with rooftop solar and timers or solar diversion to run the unit during the sunniest part of the day.
If you are weighing up electric hot water vs gas hot water, or solar hot water vs electric hot water, it is worth looking closely at lifetime running costs, not just the upfront sticker. The most efficient hot water system for your place might be a Sanden heat pump, a roof‑mounted rheem solar hot water system with a solar hot water tank replacement, or a compact rinnai solar hot water or chromagen solar hot water setup. A good installer will also talk through solar hot water repair and general hot water repair options if your existing unit still has some life left.
If your current unit is more than ten years old, running out of hot water, or needing regular hot water repair, it is a good time to check whether your Dirk Hartog home is ready for a hot water upgrade.
