Heat Pump vs Gas Hot Water Cost - What’s Better Long-Term?

When comparing heat pump vs gas hot water costs, it’s important to consider both upfront and long-term savings.

Heat Pump Systems

Higher upfront cost, but very low energy usage. They can cut electricity use by up to 70% compared to traditional electric storage systems, making them ideal for energy-conscious homes. STC rebates can also reduce your out-of-pocket cost.

Continuous Flow Systems

Lower purchase price, fast recovery, and reliable performance for high-usage households. Gas is often cheaper than electricity in Perth, but ongoing costs can still add up depending on usage.
