When you compare heat pump vs solar hot water, both can dramatically cut running costs compared with a traditional electric hot water system. Typical savings in Cowa look like this:
• Old electric to heat pump: save roughly $350–$700 per year on bills. • Gas to heat pump: save around $250–$600 per year. • Gas to solar hot water: save about $250–$650 per year. • Old electric to modern electric hot water installation with rooftop solar: save $250–$550 per year.
