• Old electric to heat pump hot water system: save about $350–$650 per year. • Gas to heat pump hot water system: save about $250–$500 per year. • Gas to solar hot water system: save about $200–$450 per year. • Old electric to modern electric hot water installation with solar: save about $200–$400 per year.
