Swapping an old electric hot water system for a quality heat pump or solar hot water system can cut that chunk of the bill dramatically. As a rough guide, many households see average annual bill savings like:
• Old electric to heat pump hot water system: about $400–$800 a year • Gas to heat pump hot water system: about $300–$700 a year • Gas to solar hot water system: about $300–$700 a year • Old electric to modern electric hot water system run on rooftop solar: about $250–$600 a year

When weighing up heat pump vs solar hot water, it often comes down to roof space, budget and how much sun your roof gets. A heat pump hot water installation can suit shaded or smaller roofs and still deliver a very energy efficient hot water system. A solar hot water installation will usually give the lowest running costs if your roof has good north‑facing exposure. Either way, modern systems are designed to work well with rooftop solar, smart timers and off‑peak tariffs to keep hot water system price and running costs under control.
