With an average household size of around 2.4 people and more than 5,800 families in the postcode, hot water is a big chunk of the power bill. As electricity prices climb and many homes move away from bottled or mains gas, upgrading from an old gas or electric hot water system to a modern, efficient option is becoming the obvious next step.
Corangula is well suited to a solar hot water system or a heat pump hot water system. Nearby Willawarrin records mean daily solar exposure of about 17.1 MJ/m² – roughly 4.75 kWh/m² of sunshine a day over the year – which is excellent for both solar hot water heating systems and high performance heat pumps.

In the 2440 postcode there are 8,170 occupied private dwellings, most of them separate houses with three or four bedrooms, so hot water demand is steady year round. Many of these homes still rely on older electric hot water systems or gas storage units, which are among the most expensive ways to heat water. Replacing them with an energy efficient hot water system – whether that is a heat pump hot water installation, a solar hot water installation or a well controlled electric hot water installation matched to rooftop solar – can shave a big slice off the power bill while improving comfort.
On average, households in areas like Corangula can expect these sorts of annual bill savings when they upgrade their hot water system:
• Old electric to heat pump hot water system: $400–$800 per year • Gas storage to heat pump hot water system: $300–$600 per year • Gas storage to solar hot water system: $300–$700 per year • Old electric to modern electric hot water system with solar: $250–$500 per year
Local homes are choosing reputable brands such as Rheem heat pump hot water units, Sanden heat pump systems, Rinnai solar hot water and Chromagen solar hot water for reliable performance and long warranties. Many households also look for the best heat pump hot water system or the best hot water system Australia wide that suits their roof space, water use and budget, rather than just replacing like-for-like. For some, a high efficiency electric hot water system paired with solar makes sense; for others, a dedicated solar hot water tank replacement or a full heat pump upgrade delivers the most efficient hot water system for their situation.
