In the 2250 area there are thousands of separate houses, many with three or four bedrooms, so hot water demand is steady all year. A lot of older homes still run gas or resistive electric cylinders, which are far less efficient than today’s options. Modern brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are increasingly visible on local homes, alongside systems such as Chromagen solar hot water and efficient electric storage units. Many residents now pair a heat pump hot water installation or solar hot water installation with existing rooftop solar to soak up excess daytime generation.
Typical annual bill savings in Lisarow for a well‑matched upgrade can look like: • Old electric to heat pump: save roughly $400–$800 per year • Gas to heat pump: save around $300–$600 per year • Gas to solar hot water: save about $250–$550 per year • Old electric to new electric hot water system with solar: save roughly $250–$500 per year
Since 2001, around 1,903 efficient hot water systems have been installed in the 2250 postcode, including both heat pump and solar hot water systems. Installations peaked around 2009–2011, when more than 800 systems went in over just three years, and there has been a steady trickle of new hot water installation work every year since. This long‑term trend shows strong local interest in electrification, lower running costs and moving towards the most efficient hot water system for each home.
