Bunnan’s climate is well suited to efficient hot water. Nearby Sandy Hollow records mean daily solar exposure of about 17.4 MJ/m², which is roughly 4.8 kWh/m² per day. That strong sunlight helps a solar hot water system or heat pump hot water system perform reliably year‑round, especially when paired with rooftop solar. For many homes, hot water can account for a quarter or more of total electricity use, so shifting to an energy efficient hot water system can deliver meaningful savings every year.
In the 2337 postcode there are 3,000‑plus occupied dwellings, most of them separate houses with three or four bedrooms, so hot water demand is solid. Families with kids, older couples and working households all need consistent hot water for showers, washing and farm or workshop clean‑ups. That’s why the choice between a heat pump hot water system, solar hot water heating system and a modern electric hot water system really matters. Compared with older gas units, electric hot water vs gas hot water is increasingly coming out in favour of efficient electric, especially when you add solar or off‑peak tariffs.
Average annual bill savings in Bunnan for common upgrade paths can look like this:
