Across Casula and the wider 2170 area, more households are switching to energy efficient hot water systems to get away from old gas units and power‑hungry cylinders. With an average household size of around 2.9 people and a big mix of family homes and apartments, reliable hot water is non‑negotiable – but so are power bills when the median household income is about $1,566 a week and mortgages and rent are already high.

Casula’s solar exposure is a real asset. The local Liverpool weather station records mean daily solar energy of about 16.2 MJ/m², which is roughly 4.5 kWh of sun per square metre per day across the year. That is plenty to drive a solar hot water heating system or support a heat pump hot water system running on daytime solar power. With more than 36,000 occupied dwellings in the 2170 postcode and a strong share of homes owned with a mortgage, every percentage point shaved off hot water energy use adds up to serious annual savings for families.
In Casula, hot water demand is steady thanks to a young median age of 35 and thousands of families with children. Hot water typically makes up 20–30% of household energy use, so choosing the most efficient hot water system you can is one of the fastest ways to cut bills. Homeowners are comparing heat pump vs solar hot water, looking at solar hot water vs electric hot water, and weighing up electric hot water vs gas hot water to find the best hot water system Australia can offer for their situation. Brands like Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and premium options such as Sanden heat pump units are all common choices for a modern, energy efficient hot water system in Casula.

Hot Water Rebates, Tariffs & Savings
Around Casula, many households are now looking at replacing old gas or electric units with a heat pump hot water system, a modern electric hot water system or a solar hot water system to get ahead of rising energy prices. Federal incentives such as Small‑scale Technology Certificates (STCs) apply nationwide and can reduce the upfront hot water system price / cost for eligible solar hot water and heat pump units.
