Hot water systems in Goolwa South
In Goolwa South, more locals are swapping old gas and tired electric units for an energy efficient hot water system that keeps bills down and comfort up. With most homes here being separate houses and an average household size of around two people, a right sized hot water system can make a real dent in running costs. Many households are on fixed incomes, with median household income under $1,000 a week, so trimming hot water energy use is a smart next step after insulation and solar.
Our coastal climate is ideal for efficient hot water. The nearby Hindmarsh Island Marina weather station records an average of about 16.8 MJ/m² of sun a day – roughly 4.7 kWh/m² – which is excellent for a solar hot water system or a modern heat pump hot water system. That strong solar exposure means a solar hot water heating system or a quality heat pump can slash the electricity needed to deliver reliable showers all year round. When you look at the high proportion of homes owned outright in 5214, upgrading an ageing electric hot water system before it fails is also a smart way to protect your property and avoid emergency call-outs.
Across the 5214 postcode, efficient hot water systems are steadily appearing on more driveways and roofs. Many homes already have rooftop solar, so pairing that with a heat pump hot water installation or electric hot water installation on a timer lets you soak up cheap daytime solar power instead of paying peak tariffs. Hot water accounts for a big share of household energy use, especially in smaller homes, so switching from gas to a heat pump hot water system or from an old electric unit to a modern, well insulated tank can deliver meaningful savings without changing your lifestyle.
Typical annual bill savings in Goolwa South can look like this:
