As a guide, moving from an old electric hot water system to a quality heat pump hot water installation can often cut hot water energy use by 60–70%. That can translate into average annual bill savings like:
• Old electric to heat pump: $400–$800 per year • Gas to heat pump: $300–$600 per year • Gas to solar hot water: $250–$550 per year • Old electric to modern electric with solar: $250–$500 per year
These are ballpark figures, but they show why efficient hot water is now seen as one of the best hot water system Australia upgrades for payback and comfort.

Hot Water Rebates, Tariffs & Savings
Across Austinmer, interest is growing in replacing old gas or resistive electric units with efficient options like a heat pump hot water system, a new solar hot water system, or a modern electric hot water system paired with rooftop solar. Homeowners are looking closely at hot water system cost, heat pump hot water price and solar hot water price, and then factoring in rebates and long‑term savings.
