Typical savings for local households can look like this:

• Old electric hot water to heat pump: around $350–$700 a year off bills. • Gas hot water to heat pump: roughly $250–$600 a year saved. • Gas to solar hot water: about $200–$550 a year in bill reductions. • Old electric to modern electric hot water system with solar: around $200–$500 a year, depending on usage and solar size.
