Hot water systems in Carrajung
Across Carrajung and the wider 3844 area, more households are moving away from old gas and power‑hungry electric hot water towards efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an average household size of about 2.4 people and more than 12,000 occupied dwellings in the postcode, hot water is a big slice of local energy use, so upgrading your hot water system can make a real dent in bills.
Carrajung’s climate is well suited to efficient hot water.

That level of sunshine gives both a solar hot water heating system and a quality heat pump hot water system plenty to work with, especially when paired with rooftop solar. For many owner‑occupiers in the area – nearly 9,000 homes are owned outright or with a mortgage – shifting from older gas or resistive electric to an energy efficient hot water system is a logical next step in cutting running costs and emissions.
Families and retirees are both well represented locally, and many homes have three or four bedrooms, which means regular showers, laundry and dishwashing. In a typical Carrajung home, hot water can be one of the biggest single energy users, so the annual hot water energy savings from an upgrade can be substantial, particularly if you move to the most efficient hot water system your budget allows.
Around 2,236 efficient hot water systems have already been installed in the 3844 postcode, including heat pump hot water installation and solar hot water installation. Install numbers really picked up from 2008, peaking around 2010 and again in 2021, with strong interest continuing through 2022–2024. This steady growth shows more Carrajung households are thinking about electrification, lower running costs and using local sunshine to power their hot water.
