Hot water systems in Karragarra Island

On Karragarra Island, more homeowners are swapping old gas and tired electric units for an energy efficient hot water system that suits island life. With many residents on fixed incomes and a median household income of just $761 a week, running costs really matter. Smaller households (average size only 1.9 people) still use a lot of energy for showers, washing and cleaning, so upgrading your hot water system is one of the easiest ways to bring bills down.

Karragarra Island is blessed with sunshine. The local weather station records around 18.7 MJ/m² of solar exposure a day on average – roughly 5.2 kWh/m² – which is ideal for both a solar hot water system and a modern heat pump hot water system. That strong solar resource means a solar hot water heating system or high quality heat pump can deliver reliable hot water with far less grid power than an older electric hot water system, especially when paired with rooftop solar.

With more than 4,100 occupied private dwellings and many owned outright, plenty of locals are in a good position to invest in upgrades that cut long‑term costs. Moving from electric hot water vs gas hot water towards efficient all‑electric options is a logical next step in electrifying homes on the bay islands. Annual hot water energy savings can be significant when you replace an old system before it fails, rather than rushing into the cheapest like‑for‑like replacement.

For local homes, a typical heat pump hot water installation or solar hot water tank replacement is sized around actual usage and roof space.
