When you replace an old gas storage unit, annual hot water energy savings can easily reach hundreds of dollars, especially if you have rooftop solar already.
In postcode 2328, most dwellings are separate houses with three or four bedrooms, so hot water demand tends to be steady rather than extreme. That suits a correctly sized hot water installation beautifully, whether you are looking at a compact heat pump for a couple or a larger solar hot water tank replacement for a busy family. Brands like Rheem heat pump hot water and Sanden heat pump units are popular for their efficiency, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water options are well known choices when you want to make the most of the roof. If you prefer to keep things simple, a quality modern electric hot water installation can still be an energy efficient hot water system when paired with solar.

• Old electric to heat pump hot water system: save roughly $350–$700 per year on bills. • Gas storage to heat pump: save around $250–$600 per year, plus avoid future gas price rises. • Gas to solar hot water system: save about $200–$500 per year, more with good solar exposure. • Old electric to new electric hot water system using rooftop solar: save $200–$450 per year.
When you compare heat pump vs solar hot water, both can be the most efficient hot water system for different homes.
