In the 6065 area, separate houses dominate, and hot water use is a big slice of the electricity bill. Many homes are moving away from gas hot water towards all electric hot water system options that work brilliantly with solar. Local installers are fitting brands like Rheem heat pump hot water and Rheem solar hot water, Rinnai solar hot water and premium Sanden heat pump units, along with Chromagen solar hot water systems, to match different budgets and roof layouts. For some households, a modern electric hot water system with timers and solar control still makes sense, especially when combined with an electric hot water system rebate.

• Old electric to heat pump hot water installation: save roughly $350–$700 per year. • Gas to heat pump vs solar hot water: often $250–$600 per year, depending on gas tariffs. • Gas to solar hot water installation: around $200–$500 per year. • Old electric to modern electric hot water installation with rooftop solar: about $200–$450 per year.
Over time, those savings can easily outweigh the hot water system price.
