Indicative price ranges
Indicative ranges only. These figures are broad planning ranges, not quotes. Prices vary by location, installer, products and site conditions. Always compare itemised quotes.
| Item | Indicative range |
|---|---|
| Supply and install, before incentives | about $3,000 – $6,000 |
| Extras: relocation, electrical work, gas disconnection | varies — ask for itemised pricing |
Depending on your state and what you're replacing, incentives can reduce the price substantially. In some cases offers advertise very low upfront prices — check exactly which product is being installed and what's included.
Running costs
A heat pump typically uses much less electricity than an electric storage system for the same hot water. If you have solar, running it during the day on a timer can cut running costs further.
