With an average household size of around 2.5 people and more than 14,000 dwellings in the postcode, reliable, affordable hot water is a big part of everyday life.

With a healthy mix of homes owned outright and with a mortgage in 2232, plenty of locals are now looking at long‑term savings rather than just the upfront hot water system price.
Around Wattamolla, hot water energy use can be one of the biggest single loads in the home, particularly in older houses still running gas or a basic electric storage unit. Swapping to the most efficient hot water system you can reasonably afford can cut that usage dramatically. Brands like Rheem heat pump hot water units, Sanden heat pump systems and solar options from Rheem solar hot water or Rinnai solar hot water are popular choices for households wanting an energy efficient hot water system that works with existing or future rooftop solar. For some homes, a modern electric hot water installation set up to run on solar power can beat gas on both cost and emissions, changing the usual electric hot water vs gas hot water equation.

• Old electric to quality heat pump hot water system: about $400–$800 per year • Gas storage to heat pump: about $300–$600 per year • Gas storage to solar hot water system: about $250–$550 per year • Old electric to new electric hot water system with solar: about $250–$500 per year
